US 12,016,019 B2 · Multiple TRP PDSCH scheduling using DCI without TCI field

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.

Dependent claims

An apparatus for wireless communication at a user equipment (UE), comprising:

memory;
and
at least one processor coupled to the memory and configured to:
receive a single downlink control information (DCI) from one transmission and reception point (TRP) of a base station or multiple DCIs from multiple TRPs of the base station that do not contain a transmission configuration indicator (TCI) state;
and
receive physical downlink shared channel (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, wherein the TCI state for each of the multiple TRPs is based on TCI states for a previous PDSCH in a same bandwidth part (BWP) or in a same carrier component (CC).
