Abstract:
Aspects presented herein may enable a UE and/or a base station to identify a TCI state for each of the multiple TRPs when the DCI does not include a TCI state. For examples, aspects presented herein may enable the UE and/or the base station to identify TCI states from different TRPs based at least in part on one of a default beam rule, the TCI state used for transmitting PDCCH, or the TCI state used for transmitting previous/last PDSCH. In one aspect, an apparatus receives a single DCI from one TRP of a base station or multiple DCIs from multiple TRPs of the base station that do not contain a TCI state. Then the apparatus receive PDSCH from the multiple TRPs of the base station based on a TCI state in which the PDSCH is to be transmitted from each of the multiple TRPs of the base station.
