TECHNIQUES FOR COHERENT JOINT TRANSMISSION FOR A MULTI-TRANSMIT AND RECEIVE POINT (TRP) WITH A DIFFERENT PHYSICAL CELL IDENTIFIER (PCID) BY USING A TYPE-II PORT SELECTION CODEBOOK

Abstract:

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, related to techniques for multiple transmission and reception point (TRP) transmission of channel state information reference signal (CSI-RS) resources. In one aspect, a user equipment (UE) can receive a CSI-RS resource including a first CSI-RS port on a first beam from a first cell of a network entity, the CSI-RS resource including a second CSI-RS port of the second cell on a second beam from a second cell of the network entity. In another aspect, a network entity can transmit, on a first beam from a first cell to a UE, a CSI-RS resource including a first CSI-RS port of the first cell, and transmit, on a second beam from a second cell to the UE, the CSI-RS resource including a second CSI-RS port of the second cell.
