Background art

Smartphones of today need to support numerous frequency bands in the sub 6 GHz (or sub 7 GHz) frequency range including carrier aggregation requirements for aggregation of two or more system bandwidths/bandwidth parts (in different frequency bands or in the same frequency band). Since other requirements, such as requirements of at least 2 receiver antennas (as in e.g., Long-Term Evolution, LTE) and sometimes 4 receiver antennas (e.g., for some frequency bands in New Radio, NR) need to be fulfilled as well, the transceiver architecture will become quite complex.

A solution to handle the frequency band complexity in sub 6 GHz (or in sub 7 GHz) is an architecture with a common transceiver, comprising analog baseband (BB) filters and BB amplifiers, e.g., variable gain amplifiers (VGAs), local oscillators (LO), phase locked loops (PLLs), mixers, up converters, down converters, and possible low noise amplifiers (LNAs), for all sub 6 GHz (or sub 7 GHz) frequency bands. Furthermore, the output (i.e., the transmitted radio signal or the received radio signal) is connected to one or more sub 6 GHz (or sub 7 GHz) front end modules, comprising power amplifiers (PAs), band filters and possible LNAs (for some frequency bands), and duplex filters. The common transceiver is connected, typically via an analog interface, to a baseband (BB) processor comprising analog-to-digital converters (ADCs) and/or digital-to-analog converters (DACs), digital filters and digital processors for further digital processing of the received (and/or the transmitted) signal. The introduction of millimeter wave (mmW) in 5G-NR, increases the capacity of the cellular system (e.g., by off-loading devices to mmW from the sub 6 GHz spectrum) and enables higher transmission rates, e.g., transmission rates of Gb/s.

In order to mitigate the higher path loss in mmW, a higher number of antennas is needed to beamform the signal. Typically, analog beamforming is used. In analog beamforming (BF) the signal from each antenna is combined in the analog domain using phase shifters.

Furthermore, in order to mitigate hand blocking (e.g., when a user blocks an antenna panel, e.g., with a hand) a number (typically 2-4) of antenna panels are needed in the mobile phone. Hence, logic circuits in the mobile phone will need to be able to switch between the different antenna panels and utilize an antenna panel that is not blocked (e.g., in order to transmit/receive a radio signal with higher or sufficient quality).

The state-of-the-art solution of adding mmW transceivers is by down converting the mmW radio signal to a sub 6 GHz signal, at the receiving side, and then feed the down converted signal to a sub 6 GHz transceiver (and up converting a sub 6 GHz signal from the sub 6 GHz transceiver to a mmW radio signal for transmission). Hence, the mmW front ends will not only comprise PAs, LNAs and band filters, but also mixers, up converters, and downconverters, converting the mmW signal to an intermediate frequency (IF) signal.

Figures 4-5 illustrates two prior art solutions, in which a control unit (CU), such as a BB processor, controls the transmission over mmW and sub 6 GHz based on conditions, such as channel conditions. The CU also controls a switch for switching between use of one of two different mmW antenna panels 402, 404 (refer to figure 4) or between use of one of two different mmW front end (Fe) transceivers 502, 504, each Fe transceiver connected to a corresponding antenna panel (refer to figure 5).

Observing figures 4 and 5, it can be deduced that there may be a need for transmission of numerous analog signals in parallel from the BB processor to the sub 6 GHz transceiver and further from the sub 6 GHz transceiver to the sub 6GHz and mmW Fes, e.g., one analog signa l/l i ne for each received and/or for each transmitted radio signal. For 5G-NR at least 4 antenna ports for reception of sub 6 GHz signals are required and at least 2 antenna ports for reception of mmW is needed. Thus, an analog interface (e.g., between the BB processor and the sub 6 GHz transceiver or between the sub 6 GHz transceiver and the sub 6 GHz/mmW Fes) need to support the transmission of at least 6 parallel analog information signals/streams. For each information signal/stream, control information needs to be sent over the interface and hence an increased number of information signals/streams increases the need for I/O pins as well as the need for more ADCs/DACs, thus enlarging a chip/printed circuit board (PCB), comprising the BB processor, and increasing the cost of the chip/PCB/BB processor.

Furthermore, analog beamforming utilizing only 2 or 3 mmW Front ends may not give full advantage of mmW transmission. Therefore, more antenna panel, e.g., 4, for mmW transmission or a digital BF solution may be desirable. However, such solutions may increase the number of analog information signals/streams and consequently the size and cost of the chip/PCB/BB processor. Thus, there may be a need for a method and/or an apparatus enabling the utilization of more antenna panels, e.g., without increasing the size of the chip/PCB/BB processor.

Furthermore, a TNode may be a BS for a neighbouring cell, a BS for a handover (HO) candidate cell, a radio unit (RRU), a distributed unit (DU), another WD (e.g., a remote WD) or a base station (BS) for a (active/deactivated) secondary cell (SCell) or for a serving/primary cell (PCell, e.g., associated with an active TCI state), a laptop, a wireless station, a relay, a repeater device, a reconfigurable intelligent surface, or a large intelligent surface.

Herein is referred to millimetre Wave (mmW) utilization, mmW communication, mmW communication capability and mmW frequency range. The mmW frequency range is from 24.25 Gigahertz (GHz) to 71 GHz or more generally from 24 to 300 GHz. The mmW frequency range may also be referred to as Frequency Range 2 (FR2).

Herein is referred to Frequency range/band 1 (FR1) utilization, FR1 GHz communication, FR1 communication capability and FR1 frequency range/band. FR1 may also be referred to as sub 6 GHz. The sub 6 GHz frequency range/band may comprise the interval from 0.5 to 6 GHz. Furthermore, in some embodiments, FR1 may equally well be referred to as a sub 7 GHz frequency range/band, especially if the range/band comprises one or more ranges/bands in the range from 6 to 7 GHz. The sub 7 GHz frequency range/band may comprise the interval from 0.5 to 7 GHz. Moreover, in some embodiments, FR1 may equally well be referred to as a sub 8 GHz frequency range/band, especially if the range/band comprises one or more ranges/bands in the range from 6 (or 7) to 8 GHz, such as U6G, which comprises a licensed NR band in the range from 6.425 to 7.125 GHz. The sub 8 GHz frequency range/band may comprise the interval from 0.5 to 8 GHz. Thus, FR1 may comprise one or more of sub 6 GHz, sub 7 GHz, and sub 8 GHz (frequency range/band). Alternatively, FR1, the sub 6 GHz, the sub 7 GHz, or the sub 8 GHz frequency range/band may be referred to as a sub mmW frequency range/band.

Below is referred to a "processing unit". The processing unit may be a digital processor. Alternatively, the processor may be a microprocessor, a microcontroller, a central processing unit, a co-processor, a graphics processing unit, a digital signal processor, an image signal processor, a quantum processing unit, or an analog signal processor. The processing unit may comprise one or more processors and optionally other units, such as a control unit.

Below is referred to an "antenna unit". An antenna unit may be one single antenna. However, an antenna unit may also be a dual antenna, such as a dual patch antenna with a first (e.g., horizontal) and a second (e.g., vertical) polarization, thus functioning as two separate antennas or an antenna unit having two ports. Herein is referred to a "filter". A filter is a device or process that removes or adds some features, components, or frequencies from a signal.

Herein is referred to "antenna port". An antenna port comprises one or more antennas or one or more antenna units.

Herein is referred to "analog beamforming", "hybrid beamforming" and "digital beamforming". Digital beamforming means that the beamforming processing, e.g., multiplication of a coefficient, is performed before digital to analog conversion (DAC) for transmission (and after analog to digital conversion, ADC, for reception), i.e., in the digital domain. Analog beamforming means that the beamforming processing, e.g., phase shifting, is performed after DAC for transmission (and before ADC for reception), i.e., in the analog domain. Hybrid beamforming means that some beamforming processing, e.g., phase shifting, is performed after DAC and some beamforming processing, e.g., multiplication of a coefficient, is performed before DAC for transmission (and before and after ADC for reception), i.e., processing in both digital and analog domains.

Below is referred to "analog port". Each transceiver front end may require a set of analog lines. The set of analog lines may comprise two lines, e.g., one for signal and one for ground, or one for transmission and one for reception, or one for negative voltage/potential (V-) and one for positive voltage/potential (V+), one for quadrature (Q) and one for in-phase (I). Alternatively, the set of analog lines may comprise four lines, e.g., one for V- for each of Q and I, and one for V+ for each of Q and I. Furthermore, each transceiver front end may also require one or more separate control lines as indicated in figure IB. However, herein the set of analog lines is referred to as one analog port. Each analog port is associated with a respective transceiver chain (comprising an antenna unit and a transceiver).

Herein is referred to "bandwidth part". A bandwidth part (BWP) is a bandwidth configured for a WD. The BWP is a part/portion of the total/full transmission bandwidth and the WD may be configured to only monitor a BWP (instead of the full transmission bandwidth), due to the fact that the WD cannot receive the full transmission bandwidth (e.g., due to reduced capability of the WD or due to the WD being in a mode of reduced complexity), or in order to save power (e.g., if the WD has capacity for the full transmission bandwidth). Herein is referred to "frequency range configuration". A frequency range configuration may comprise a frequency range, such as a channel bandwidth, system bandwidth or a cell bandwidth, the WD is allowed to utilize or can be configured to utilize.

Herein is referred to "frequency band configuration". A frequency band configuration may comprise one or more frequency bands, such as any of the sub-6 GHz frequency bands nl-nl04 and/or any one or more FR2/mmW frequency bands from 24.25 GHz to 71.0 GHz, the WD is allowed to utilize or can be configured to utilize.

Basic concept

It can be observed that an analog interface between a FR1 transceiver and one or more FR1 transceiver front end (Fes) and/or one or more mmW transceiver Fes may be reused between the FR1 and mmW frequency bands. Then, upon current operation conditions the switch can be set, e.g., such that 2 information streams are allocated for FR1, and 4 information streams are allocated for mmW when the main communication is going through mmW, and such that 4 information streams are allocated for FR1, and 2 information streams are allocated for mmW when the main communication is going through FR1. Such a solution enables multiband (FR1 and FR2) communication, while enabling hybrid beamforming (or digital beamforming), which is much more robust towards non-line of sight (nLoS) and hand blocking, without increasing the number of analog ports for the FR1 transceiver.

Embodiments

In the following, embodiments will be described where figure 1A illustrates method steps of a method 100 according to some embodiments and figure IB illustrates a wireless device 700 according to some embodiments.

The WD comprises a processor, such as a general-purpose processor or a baseband (BB) processor 610. Moreover, in some embodiments, the WD 700 is operatively connected or connectable to a remote transceiver node (TNode). Alternatively, the WD 700 is operatively connected or connectable to two different TNodes. Furthermore, the AHI 630 comprises a transceiver front end (Fe) interface 632.

Furthermore, the AHI 630 comprises a control unit (CU) 638. The method 100 comprises obtaining 110 device status information (for or associated with the WD 700). The device status information may be obtained from a pre-defined rule, such as from a standard.

As another alternative, or in addition, the device status information is obtained from one or more higher layer configurations, such as from a Non-access Stratum (NAS) layer configuration or from an application layer configuration. As yet another alternative, or in addition, the device status information is obtained from a device condition, such as an overheating indication or a BB processor load indicator. In some embodiments, the device status information comprises a configuration. The configuration may be a first configuration (which is) associated with the WD 700 being operatively connected to a first remote transceiver node (TNode), e.g., only. Le., the first configuration specifies how to configure the WD 700 (or components thereof) when/while the WD 700 is operatively connected to a first remote TNode (without being operatively connected to a second remote TNode). Alternatively, the configuration is a second configuration (which is) associated with the WD 700 being operatively connected to a first and a second remote TNode. Le., the second configuration specifies how to configure the WD 700 (or components thereof) when/while the WD 700 is operatively connected to first and second remote TNodes (simultaneously). In some embodiments, "being operatively connected to" comprises (or consists of) being in communication with or having established communication with. In some embodiments, the first configuration is one or more of: a FR1 connection; a mmW connection; a carrier aggregation configuration; a dual connectivity configuration; a frequency band configuration; a frequency range configuration; a bandwidth part configuration; a transmission configuration; and a reception configuration. Furthermore, in some embodiments, the second configuration is one or more of: a FR1 connection; a mmW connection; a carrier aggregation configuration; a dual connectivity configuration; a frequency band configuration; a frequency range configuration; a bandwidth part configuration; a transmission configuration; and a reception configuration. As another alternative, the device status information comprises a signal quality metric for each of the transceiver Fes 640, 650, 660 of the first and second sets, or for each of the transceiver Fes of the first and second sets to be utilized when in the specified configuration (i.e., the first or second configuration), when connected to the first and/or the second remote TNode. In some embodiments, the signal quality metric is one or more of a Signal-to-noise ratio (SNR), a Reference Signal Received Power (RSRP), a Received Signal Strength Indicator (RSSI), and a Reference Signal Received Quality (RSRQ). As yet another alternative, the device status information comprises a spatial three-dimensional (3D) position of the WD 700. E.g., in some embodiments, the WD 700 comprises one or more sensors 720, 722, 724, such as one or more accelerometers, one or more gyroscopes, one or more Global navigation satellite system, GNSS, receivers (e.g., Global Positioning System, GPS, receivers), one or more cameras, one or more finger sensors, one or more fingerprint sensors, one or more touch sensors, and/or one or more radar transceivers. As an example, one or more accelerometers, gyroscopes and/or GPS receivers may be utilized for determining a spatial 3D position of the WD 700. Thus, the spatial 3D position of the WD 700 may be determined based on (in accordance with; in dependence of) the one or more sensors 720, 722, 724, based on (in accordance with; in dependence of) an output of the one or more sensors 720, 722, 724 or based on (in accordance with; in dependence of) a measurement result of the one or more sensors 720, 722, 724. As another example, one or more cameras, one or more finger sensors, one or more fingerprint sensors, one or more touch sensors, and/or one or more radar transceivers may be utilized for determining a spatial 3D position or for providing a better accuracy for a (determined) spatial 3D position. In these embodiments/alternatives, the CU 638 is configured to control the ASA 636 to connect the first subset of the first set and the second subset of the second set to the FR1 transceiver 620 based on (or in accordance with or in dependence of) the first configuration, the second configuration, the signal quality metric and/or the spatial 3D position.

Furthermore, in some embodiments, one of the first and second subset is empty, i.e., there are no transceivers in the first subset or there are no transceivers in the second subset. The number of transceivers comprised in any of the first and second subsets is less than or equal to the number of analog ports. Thus, not all transceivers of the first and second sets will be utilized at the same time (e.g., as there are more transceivers 642, 652, 654, 656, 658 than available analog ports, connected or connectable to the processing unit).

In some embodiments, one or more sensors 720, 722, 724, such as one or more cameras, one or more finger sensors, one or more fingerprint sensors, one or more touch sensors, and/or one or more radar transceivers, may be utilized for determining if one or more antenna ports/units/panels are blocked (e.g., by a hand or finger). This information (whether or not an antenna port/unit/panel is blocked) may then be utilized as device status information (for or associated with the WD 700), i.e., the device status information may comprise information about blocked and/or non-blocked antenna ports/units/panels. Alternatively, the information (whether or not an antenna port/unit/panel is blocked) is utilized to perform an action, such as informing a user of the WD 700 that the user is blocking an antenna port/unit/panel, which otherwise (if not blocked) could have improved reception and/or transmission. In some embodiments, the WD 700 comprises one or more haptic sensors, one or more speakers, and/or one or more displays. The user may, in some embodiments, be informed (that the user is blocking an antenna port/unit/panel) by haptic feedback from one or more haptic sensors. In some embodiments, the haptic sensors are located around the WD 700 and thus, the user will be made aware by the haptic feedback which finger or fingers that are blocking the antenna port/unit/panel. Alternatively, the user may be informed by a beeping sound outputted by the speaker that that the user is blocking an antenna port/unit/panel. Once the blocking finger(s) has been removed, the beeping sound will disappear/be silenced. As another alternative, the speaker may output instructions (in accordance with the information about blocked and/or non-blocked antenna ports/units/panels) for the user. The instructions may be in the form of what part of the WD 700 that should not be covered by a hand, e.g., "please, remove your fingers/hand from the top of the wireless device". As yet another alternative, the user may be informed by a message on the display that the user is blocking an antenna port/unit/panel. The message may be a text message or a graphical message. In some embodiments, the message is a text message in the form of "please, remove your fingers/hand from the top of the wireless device". By giving the user feedback regarding blocking of antenna ports/units/panels, a reduced power consumption as well as an improved reception and/or transmission may be achieved (by enabling the user to mitigate the problem). In some embodiments, credits in a game are given to a user in accordance with fulfilment of the information/recommendations given by the feedback. This may be advantageous, since the system will be more robust, system through-put may be increased and/or power consumption may be reduced.

In some embodiments (e.g., the embodiments in which the device status information comprises a configuration), the method further comprises determining 112 whether the configuration requires the utilization of more transceiver Fes than the BB processor 610 is able to handle and in response to determining that the configuration requires the utilization of more transceiver Fes than the BB processor 610 is able to handle, prioritizing 114 the first set of transceiver Fes or the second set of transceiver Fes based on (in accordance with) one or more prioritization rules, i.e., allocating more, e.g., all available, transceiver Fes to the first set than to the second set and vice versa in accordance with one or more prioritization rules. Prioritization may be necessary due to a limited number of analog connections/ports/lines between the BB processor and the transceiver Fes, via the FR1 transceiver or via transceiver chains. The one or more prioritization rules may be one or more of a pre-determined prioritization rule, a prioritization rule based on the first or the second configuration, and a prioritization rule based on a current channel signal quality. Prioritization may be advantageous, e.g., since more consistent prioritization among devices may be achieved, since a more predictable behaviour on system level is achieved, and/or since the capacity may be improved/increased. In some embodiments, the WD 700 performs the prioritization, e.g., according to a pre-determined prioritization rule, stored at the WD 700. Alternatively, a TNode configures a group of one or more wireless devices, comprising the WD 700, with a prioritization rule, e.g., by transmitting the prioritization rule to the group of one or more wireless devices, and the WD 700 performs prioritization based on the received prioritization rule. This may be advantageous, since more consistent prioritization among the wireless devices connected to the TNode, i.e., the wireless devices of the group of one or more wireless devices, is achieved and/or since capacity of the system is improved/increased.

In some embodiments, e.g., for carrier aggregation and/or dual connectivity, the prioritization rule specifies that receiver requirements, such as quality of service, QoS, requirements, for utilization of primary cell (PCell) are based on or are in accordance with that configured services for current channel characteristics are fulfilled. This may be advantageous, e.g., since a PCell may require more transceivers if the signal quality (e.g., SNR) is low, e.g., lower than a threshold, than if it is high, e.g., higher than a threshold. Furthermore, since the majority of control signalling is on the PCell in these embodiments, a more robust connection may be achieved. In these embodiments, the remaining available analog ports may, in some embodiments, be allocated to SCell frequency bands (for utilization of an SCell).

Furthermore, in some embodiments (e.g., in dual connectivity), the prioritization rule specifies that a PCell is prioritized over a primary secondary cell, PSCel I . Moreover, in some embodiments, the prioritization rule further specifies that the PSCell is prioritized over a first secondary cell, SCell, on a PCell carrier. This may be advantageous, e.g., since such prioritization ensures that a sufficient number of transceivers are allocated to both PCell and PSCell and/or that robust control signalling is achieved for both connections.

In some embodiments, the prioritization rule specifies that a first SCell is prioritized over a second SCell based on a first frequency band associated with the first SCell and/or based on a second frequency band associated with the second SCell. The first frequency band may be a FR1 frequency band, and the second frequency band may be a mmW frequency band. This prioritization rule may be applicable to high reliability low data rate services. Furthermore, such prioritization may be advantageous, e.g., since a more robust transmission and/or a larger coverage is achieved. Alternatively, the first frequency band is a mmW frequency band and the second frequency band is a sub 6GHz frequency band. This may be advantageous, e.g., since higher data rates are typically achieved at mmW, due to larger bandwidth (BW), thus achieving higher user throughput (and/or higher capacity in the system).

Furthermore, in some embodiments, the prioritization rule specifies that a first frequency band (frequency range, bandwidth part, or system bandwidth) is prioritized over a second frequency band (frequency range, bandwidth part, or system bandwidth), and that the first frequency band is wider than the second frequency band. This may be advantageous, since a higher overall data throughput may be achieved.

Moreover, in some embodiments, the prioritization rule specifies that the first subset comprises two or more transceiver front ends and/or that the second subset comprises two or more transceiver front ends. This may be advantageous, e.g., since a more robust connection may be obtained and/or since such prioritization makes multiple input, multiple output (MIMO)/beamforming on both frequency bands possible and/or since the capacity is improved/increased.

In some embodiments, the prioritization rule further specifies that the first subset comprises the two or more transceiver front ends of the first set being associated with lower frequency bands than all other transceiver front ends of the first set (the two transceiver Fes of the first set with the lowest frequency band) and/or that the second subset comprises the two or more transceiver front ends of the second set being associated with lower frequency bands than all other transceiver front ends of the second set (the two transceiver Fes of the second set with the lowest frequency band). Thereby, a more robust system may be obtained.

Furthermore, if it is determined (during determining 112) that the configuration does not require the utilization of more transceiver front ends than the BB processor can handle/manage, no prioritization is performed.

Moreover, the method 100 comprises controlling 120, e.g., by the CU 638, the ASA 636 to connect a first subset of the first set and a second subset of the second set to the analog ports. The controlling 120 is based on (according to or in dependence of) the obtained device status information. Moreover, the number of transceiver Fes comprised in the first subset plus the number of transceiver Fes comprised in the second subset is less than or equal to the third number (of analog ports). Thus, not all transceiver Fes of the first and second sets will be utilized at the same time (e.g., as there are more transceiver Fes than analog ports, connected or connectable to the FR1 transceiver 620, available). As an example, the first set of transceiver Fes may comprise 6 FR1 transceiver Fes (or the first number may be 6), the second set of transceiver Fes may comprise 6 mmW transceiver Fes (or the second number may be 6) and there may be 8 analog ports (or the third number may be 8). Alternatively, the first set of transceiver Fes may comprise 12 FR1 transceiver Fes (or the first number may be 12), the second set of transceiver Fes may comprise 12 mmW transceiver Fes (or the second number may be 12) and there may be 16 analog ports (or the third number may be 16). As yet another alternative, the first set of transceiver Fes may comprise 4 FR1 transceiver Fes (or the first number may be 4), the second set of transceiver Fes may comprise 4 mmW transceiver Fes (or the second number may be 4) and there may be 6 analog ports (or the third number may be 6).

Figure IB illustrates a wireless device (WD) 700 according to some embodiments. The WD 700 comprises a processing unit, such as a baseband processor 610, a control unit or similar controlling circuitry. Furthermore, the WD 700 comprises a FR1 transceiver 620. In some embodiments, the FR1 transceiver 620 comprises one or more phase locked loops (PLLs), one or more local oscillators (LOs), one or more mixers, (possible LNA), one or more analog BB filters, one or more analog IF amplifiers and zero, one or more low noise amplifiers (LNAs). E.g., the FR1 transceiver 620 comprises one PLL, one LO, one mixer, one analog BB filter, one analog IF amplifier for each transceiver chain. The FR1 transceiver 620 is connected to the processor, e.g., to the BB processor 610. Moreover, the WD 700 comprises the analog hardware interface (AHI) 630 described above (the AHI 630 comprising a number of analog ports). The AHI 630 is connected to the FR1 transceiver 620. The WD 700 comprises a first set of transceiver front ends (Fes). The first set of transceiver Fes comprises a first number of FR1 transceiver front ends 640. Each of the first number of FR1 transceiver Fes 640 is connected to the analog hardware interface 630. Furthermore, the WD 700 comprises a second set of transceiver Fes. The second set of transceiver Fes comprises a second number of millimeter wave (mmW) transceiver Fes 650, 660. Each of the second number of mmW transceiver Fes 650, 660 is connected to the analog hardware interface 630. Moreover, in some embodiments, each transceiver 640, 650, 660 is connected or connectable to one or more antenna units 702, 704, 706, 708, 710, 712. Furthermore, in some embodiments, the WD 700 comprises one or more sensors 720, 722, 724. The one or more sensors may be one or more accelerometers, one or more gyroscopes, one or more Global navigation satellite system (GNSS) receivers, one or more cameras, one or more finger sensors, one or more middle finger up sensors, one or more fingerprint sensors, one or more touch sensors, one or more radar transceivers or any combination thereof. In some embodiments, each of the transceiver Fes 640, 650, 660 comprises more than one transceiver (chain), e.g., as shown in figure IB, in which figure the transceiver Fe 640 comprises 4 transceivers (chains) and each of the transceiver Fes 650, 660 comprises 2 transceivers (chains). Alternatively, each of the transceiver Fes 640, 650, 660 comprises more than one transmitter and one receiver. E.g., the transceiver Fe 640 comprises four transceivers or four transmitters and four receivers, whereas each of the transceiver Fes 650, 660 comprises two transceivers or two transmitters and two receivers. Thus, in some embodiments, the transceiver Fe 640 is connected to the antenna units 702, 704, 706, 708, the transceiver Fe 650 is connected to the antenna unit 710, and the transceiver Fe 660 is connected to the antenna unit 712. Furthermore, in some embodiments, the antenna units 710 and 712 comprises more than 2 antennas, such as 4 or 8 antennas. Moreover, in some embodiments, the WD 700 comprises the antenna units 702, 704, 706, 708, 710, 712. As described above the AHI comprises a control unit (CU) 638. Alternatively, the WD 700 comprises the CU 638. As yet another alternative, the CU 638 is comprisable in the WD 700. In some embodiments, the CU 638 is comprised or comprisable in the FR1 transceiver 620 or in the BB processor 610 connected to the FR1 transceiver 620. The CU 638 is configured to control or controls the analog switching arrangement (ASA) 636 of the AHI 630. In some embodiments, the ASA 636 comprises a switch for connecting either the FR1 transceiver Fe 640 (comprising two or more, such as four, transceivers chains/transceivers) or the mmW transceiver Fe 650 (comprising two transceivers chains/transceivers) to two analog ports (whereas all other analog ports are dedicated to a specific FRl/mmW transceiver Fe, e.g., 640, 660) as depicted in figure IB. Alternatively, the ASA 636 may connect any of the analog ports to any of the FRl/mmW transceiver Fes 640, 650, 660. The CU 638 is configured to control the ASA 636 to connect a first subset of the first set and a second subset of the second set to the analog ports based on device status information. The number of transceiver Fes comprised in the first subset plus the number of transceiver front ends comprised in the second subset is less than or equal to the third number, i.e., the number of analog ports of the AHI 630. Furthermore, in some embodiments, the CU 638 is (further) configured to control a fourth number of analog baseband (BB) filters. In some embodiments, the fourth number is equal to the third number. Each analog BB filter is associated with (e.g., connected, or connectable, to) a respective mixer comprised in the FR1 transceiver 620. Moreover, in some embodiments, the CU 638 is configured to adapt an analog BB filter bandwidth (BW) based on (in accordance with/in dependence of) a respective FR1 transceiver Fe, a respective mmW transceiver Fe and/or device status information.

Furthermore, in some of these embodiments, the processing unit is or comprises controlling circuitry configured to cause determination 212 of whether the configuration requires the utilization of more transceiver Fes than the processor (e.g., the BB processor 610) is able to handle/manage. To this end, the controlling circuitry may be associated with (e.g., operatively connectable, or connected, to) a determining unit (e.g., determining circuitry, or a determiner). Moreover, in some embodiments (i.e., the embodiments with determination 212), the processing unit is or comprises controlling circuitry configured to in response to determining (i.e., in response to the determination 212) that the configuration requires the utilization of more transceiver front ends than the processor (e.g., the BB processor 610) is able to handle, cause prioritization 214 of the first set of transceiver Fes or the second set of transceiver Fes based on (or in accordance with or in dependence of) one or more prioritization rules.

Thus, the steps of any methods disclosed herein do not have to be performed in the exact order disclosed, unless a step is explicitly described as following or preceding another step and/or where it is implicit that a step must follow or precede another step. In the same manner, it should be noted that in the description of embodiments, the partition of functional blocks into particular units is by no means intended as limiting. Contrarily, these partitions are merely examples. Functional blocks described herein as one unit may be split into two or more units. Furthermore, functional blocks described herein as being implemented as two or more units may be merged into fewer e.g., a single) unit. Any feature of any of the embodiments/aspects disclosed herein may be applied to any other embodiment/aspect, wherever suitable. Likewise, any advantage of any of the embodiments may apply to any other embodiments, and vice versa. Hence, it should be understood that the details of the described embodiments are merely examples brought forward for illustrative purposes, and that all variations that fall within the scope of the claims are intended to be embraced therein.
