Definition

The IE BeamFailureRecoveryRSConfig is used to configure the UE with candidate beams for beam failure recovery in case of beam failure detection. See also TS 38.321 [3], clause 5.17.

    rsrp-ThresholdBFR-r16               RSRP-Range                                                               OPTIONAL, -- Need M

Fields (3)

FieldDescription
rsrp-ThresholdBFR-r16
RSRP-Range · OPTIONAL Need M
L1-RSRP threshold used for determining whether a candidate beam may be included by the UE in MAC CE for BFR (see TS 38.321 [3] and TS 38.213 [13], clause 6). The network always configures this parameter in every instance of this IE.
candidateBeamRS-List-r16
SEQUENCE (SIZE(1..maxNrofCandidateBeams-r16)) OF CandidateBeamRS-r16 · OPTIONAL Need M
A list of reference signals (CSI-RS and/or SSB) identifying the candidate beams for recovery. The network always configures this parameter in every instance of this IE.
candidateBeamRS-List2-r17
SEQUENCE (SIZE(1..maxNrofCandidateBeams-r16)) OF CandidateBeamRS-r16 · OPTIONAL Need R
A list of reference signals (CSI-RS and/or SSB) identifying the candidate beams for recovery.
