1. A user equipment (UE), comprising:
a transceiver configured to transmit and receive wireless signals in communication with a base station; and
one or more processors configured to:
receive, from the base station, a configuration signal that includes a plurality of activated transmission configuration indicator (TCI) states for a Control Resource Set (CORESET);
decode, using a quasi-colocation provided by each of the plurality of activated TCI states, a physical downlink control channel (PDCCH);
configure a plurality of beams based on the decoded PDCCH, each of the plurality of beams corresponding to each of the plurality of activated TCI states; and
combine the plurality of beams into an aggregate beam.
