1. A method comprising:
receiving, by a wireless device from a base station, configuration parameters indicating transmission configuration indication (TCI) state pools, wherein each TCI state pool, of the TCI state pools, comprises TCI states, and wherein the TCI state pools comprise at least a first TCI state pool and a second TCI state pool;
selecting the first TCI state pool from the TCI state pools;
transmitting, to the base station, a first indication of the first TCI state pool;
receiving, from the base station, a second indication of the second TCI state pool in response to transmitting the first indication of the first TCI state pool; and
determining, based on one or more second TCI states of the second TCI state pool, an uplink spatial domain filter for transmission of uplink signals or a downlink spatial domain filter for reception of downlink signals.
