Summary: | Systems and methods are disclosed for signaling for supporting joint and separate downlink/uplink Transmission Configuration Indication (TCI) operations. In one embodiment, a method performed by a User Equipment (UE) comprises receiving a Medium Access Control (MAC) Control Element (CE) message from a network node and receiving a Downlink Control Information (DCI) from the network node comprising a TCI field set to one of a plurality of TCI field codepoints. The MAC CE maps TCI states to at least some of the TCI field codepoints. The MAC CE comprises a first field that indicates whether a first TCI state indicated by the MAC CE that is mapped to a first TCI field codepoint in the DCI is a downlink (DL) TCI state or an uplink (UL) TCI state and information that indicates whether a DL TCI state, UL TCI state, or both are indicated for the first TCI field codepoint. |
