Contention window adjustment for multiple transmit receive points

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may transmit a first physical downlink shared channel (PDSCH) communication to a user equipment (UE), wherein the first PDSCH communication includes a first set of layers for a codeword, and wherein a second set of layers for the codeword are transmitted to the UE in a second PDSCH communication from a second TRP. The first TRP may receive from the UE, acknowledgement or negative acknowledgement (ACK/NACK) information corresponding to the codeword. The first TRP may adjust a contention window size based at least in part on a determination that a condition, associated with the ACK/NACK information, is satisfied. Numerous other aspects are provided.
