1. A method comprising:
receiving, by a wireless device, at least one configuration parameter for a beam failure recovery (BFR) procedure of a plurality of cells, wherein the at least one configuration parameter indicates:
first candidate reference signals (RSs) for a first cell of the plurality of cells; and
second candidate reference signals (RSs) for a second cell of the plurality of cells; and
based on detection of beam failure of the plurality of cells, transmitting a BFR medium access control (MAC) control element (CE) indicating the detection of the beam failure of the plurality of cells, wherein the BFR MAC CE comprises:
a first field associated with a candidate RS identifier (ID) indication, wherein the first field is for the first cell of the plurality of cells, and wherein a first value for the first field has a value of zero that indicates no candidate RS, among the first candidate RSs, has a reference signal received power (RSRP) equal to or higher than a first RSRP threshold; and
a second field associated with a candidate RS ID indication, wherein the second field is for a second cell of the plurality of cells, and wherein a second value for the second field is configured to indicate information associated with a candidate RS, among the second candidate RSs, with an RSRP above a second RSRP threshold.
