1. A method comprising:
receiving, by a wireless device, one or more messages comprising one or more configuration parameters for a cell, wherein the one or more configuration parameters indicate:
transmission configuration indicator (TCI) states for decoding physical downlink shared channel (PDSCH); and
a sounding reference signal (SRS) resource;
receiving a medium access control control element (MAC CE) activating one or more TCI states of the TCI states;
in response to the one or more configuration parameters not indicating a spatial relation for the SRS resource and not indicating a control resource set in the cell, determining a spatial domain transmission filter based on a reference signal in an activated TCI state, wherein the activated TCI state has the lowest TCI state index among one or more TCI state indexes of the one or more TCI states; and
transmitting, via the SRS resource, an SRS with the spatial domain transmission filter.
