1. A method comprising:
receiving, by a wireless device from a base station, one or more messages comprising configuration parameters indicating:
a sounding reference signal (SRS) resource set;
a plurality of reference signals (RSs); and
an uplink transmission configuration indication (TCI) state comprising a configuration of one or more RSs of the plurality of RSs;
receiving a downlink control information comprising an SRS resource indicator (SRI) and an uplink TCI indicator (UL-TCI), wherein:
the SRI indicates one or more SRS resources of the SRS resource set; and
the UL-TCI indicates an uplink transmission configuration indication state;
in response to the SRI being equal to a predefined value, determining an uplink spatial domain transmission filter based on the one or more SRS resources of the SRS resource set; and
transmitting, via a physical uplink shared channel, a transport block with the uplink spatial domain transmission filter.
