1. A method comprising:
receiving, by a wireless device, one or more configuration parameters indicating a plurality of beam failure detection sets of a cell, wherein the plurality of beam failure detection sets comprise a first beam failure detection set of the cell and a second beam failure detection set of the cell;
receiving, based on a first transmission configuration indicator (TCI) state and a second TCI state, one or more first signals via a control resource set (CORESET);
transmitting, based on a beam failure associated with the first beam failure detection set, an uplink signal indicating a candidate reference signal;
receiving a response to the uplink signal; and
after receiving the response, receiving, based on the candidate reference signal and the second TCI state, one or more second signals via the CORESET.
