Updating active tci state for single-pdcch based multi-trp pdsch or multi-pdcch based multi-trp pdsch

Abstract

Systems and methods are disclosed herein for updating an active Transmission Configuration Indication (TCI) state for single- or multi-Physical Downlink Control Channel (PDCCH) based multi-Transmission/Reception Point (TRP) Physical Downlink Shared Channel (PDSCH) transmissions. In one embodiment, a method performed by a wireless communication device comprises receiving a Medium Access Control (MAC) Control Element (CE) comprising information that activates one or more TCI states for a particular serving cell and/or bandwidth part (BWP) of the wireless communication device that is configured for multi-PDCCH based multi-PDSCH transmission and maps at most one of the activated TCI states to each codepoint for a Downlink Control information (DCI) TCI field. The method further comprises receiving a PDCCH comprising a DCI in which the DCI TCI is set to a particular codepoint and determining the activated TCI state used for a PDSCH scheduled by the DCI based on the information comprised in the DCI.
