Claim 11:
12. A modem platform to be employed by a user equipment (UE), the modem platform comprising:
baseband circuitry to:
detect a beam failure in a secondary cell (SCell),
determine candidate beams of the SCell on which to camp based on measurement of corresponding Beam Failure Detection (BFD) reference signals (RSs), wherein the determination of the candidate beams includes:
determine the corresponding of BFD-RSs to measure based on a received BFD configuration,
perform measurement of the corresponding of BFD-RSs, and
determine the candidate beams to be beams associated with the measured BFD-RSs having a signal strength above a configured threshold, and
generate a Beam Failure Recovery (BFR) Medium Access Control (MAC) Control Element (CE) to include reference signal identifiers (IDs) of respective candidate beams whose corresponding BFD-RSs have a signal strength above a configured threshold; and
radiofrequency (RF) circuitry coupled with the baseband circuitry, the RF circuitry to:
transmit the BFR MAC CE to a Radio Access Network (RAN) node over the SCell or a primary cell (PCell) associated with the SCell, and
receive a BFR configuration in a BFR Control Resource Set (CORESET) of a Physical Downlink Control Channel (PDCCH) on the SCell that is quasi co-located (QCL′d) with a candidate beam indicated by the BFR MAC CE, the BFR configuration to include parameters for use of the candidate beam.
