1. A wireless device comprising:
a wireless transceiver;
at least one processor; and
a memory storing instructions that, when executed by the at least one processor, cause the wireless device to:
receive, from a base station, at least one Radio Resource Control (RRC) message, wherein the at least one RRC message comprises:
first configuration information indicating a Transmission Configuration Index (TCI) state list of a first cell; and
second configuration information indicating a TCI state list of a second cell;
receive, from the base station and via the second cell, a first Medium Access Control (MAC) Control Element (CE), wherein the first MAC CE comprises an identifier associated with the first configuration information and associated with a first TCI state identifier, and wherein the first TCI state identifier indicates a first TCI state of the TCI state list of the first cell;
monitor, based on the first MAC CE and based on the first TCI state, Physical Downlink Control Channel (PDCCH) associated with the first cell;
receive, from the base station and via the first cell, a second MAC CE, wherein the second MAC CE comprises an identifier associated with the second configuration information and associated with a second TCI state identifier, and wherein the second TCI state identifier indicates a second TCI state of the TCI state list of the second cell; and
monitor, based on the second MAC CE and based on the second TCI state, PDCCH associated with the second cell.
