ANTENNA SELECTION IN IDLE MODE

WIPO Patent Application WO/2024/082126

A1

Method and apparatus for antenna selection in idle mode. The apparatus measures a channel condition for each of a plurality of antennas at a UE. The apparatus dynamically selects, while in a RRC idle mode, at least one antenna from the plurality of antennas based on the channel condition. The apparatus may terminate measurement of the channel condition for each of the plurality of antennas in response to the channel condition on two active antennas being greater than a first threshold T0 and a PDSCH result comprises a CRC pass rate of 100%. The apparatus may trigger a measurement across the plurality of antennas in response to the channel condition across a first pair of active antennas is less than a second threshold (T1). The apparatus may determine whether a second pair of antennas have channel conditions greater than the second threshold.
