SYSTEMS AND METHODS FOR QUASI-CO-POLARIZATION DIRECTION INDICATION WITH DUAL-POLARIZED ANTENNAS

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 an 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.
