1. A method comprising:
reporting, by a wireless device, a capability of the wireless device for multiple candidate beam set monitoring;
receiving, by the wireless device, a radio resource control (RRC) message comprising:
a serving beam set;
a plurality of candidate beam sets, wherein:
each candidate beam set, of the plurality of candidate beam sets, comprises a plurality of candidate beams; and
each of the plurality of candidate beams is associated with a corresponding one of a plurality of downlink (DL) candidate reference signals (RSs); and
a monitoring priority configuration of the plurality of candidate beam sets;
detecting, by the wireless device, a beam failure of the serving beam set;
selecting, in response to the detecting, a first candidate beam set from the plurality of candidate beam sets based on the monitoring priority configuration of the plurality of candidate beam sets;
selecting a first DL candidate RS from first DL candidate RSs associated with the selected first candidate beam set based on a channel quality of the first DL candidate RS being greater than a threshold; and
transmitting a preamble associated with the first DL candidate RS for beam failure recovery.
