Unified Transmission Configuration Indication States for Multipoint Downlink Operation Using Single Control Information

A method, comprising:

• receiving, from a cellular network, an indication of a plurality of active transmission configuration indication (TCI) states for downlink (DL) communication, wherein the plurality of active TCI states is associated with a plurality of transmission and reception points (TRPs);
• receiving, from the cellular network, configuration of a first resource group for DL control communication operation, the configuration of the first resource group comprising an indication of a rule to select a TCI state for monitoring the first resource group;
• selecting, based at least in part on the configuration of the first resource group, a first TCI state of the plurality of active TCI states for monitoring the first resource group;
• and
• monitoring a control channel on the first resource group using the first TCI state.

An apparatus, comprising:

• a processor configured to, when executing instructions stored in a memory, perform operations comprising:
• receiving, from a cellular network, an indication of a plurality of active transmission configuration indication (TCI) states for downlink (DL) communication, wherein the plurality of active TCI states is associated with a plurality of transmission and reception points (TRPs);
• receiving, from the cellular network, an indication of a rule to select a TCI state for receiving channel state information (CSI) reference signals (CSI-RS);
• selecting, based at least in part on the rule, a first TCI state of the plurality of active TCI states for receiving CSI-RS;
• and
• receiving CSI-RS using the first TCI state from a first TRP of the plurality of TRPs.
