Title:
SYSTEMS AND METHODS FOR QUASI-CO-POLARIZATION DIRECTION INDICATION WITH DUAL-POLARIZED ANTENNAS
Document Type and Number:
WIPO Patent Application WO/2024/077549
Kind Code:
A1
Abstract:
Aspects of the present disclosure are directed to an indication of polarization direction association that indicates an association between a first resource with at least 1 port and a second resource with at least 1 port or between a first resource with at least 1 port and a first port of a second resource with at least 1 port to assist a user equipment (UE) in matching polarization direction with a base station in downlink (DL) reception or uplink (UL) transmission. The first resource may be one of CSI-RS, PDCCH, PDSCH, PUCCH, PUSCH, SRS, or PRACH. The second resource may be one of a SSB, CSI-RS, SRS or PRACH, and the SSB may comprise one or more of PSS, SSS, PBCH, and DMRS for PBCH. Other aspects may include group-based partitioning of antenna ports within a first resource and a second resource for providing a quasi-co-polarization direction association.
