1. An apparatus, comprising:
a processor configured to, when executing instructions stored in a memory, perform operations comprising:
communicate with a cellular network via a plurality of transmission and reception points (TRPs);
receive, from the cellular network, a configuration of a first control resource set (CORESET) comprising an indication of a rule for selecting a transmission control indication (TCI) state from a generic plurality of TCI states for downlink communication from the plurality of TRPs;
receive, from the cellular network, an indication of an activated plurality of unified TCI states for downlink communication from the plurality of TRPs;
select, based on the rule, a TCI state for control channel monitoring for the first CORESET from the activated plurality of TCI states;
monitoring a control channel for the first CORESET using the selected TCI state;
receiving, from at least one TRP of the plurality of TRPs and using the selected TCI state, a control channel message; and
exchanging data with the cellular network according to the control channel message.
