Configuration of beam failure recovery search space set for physical downlink control channel repetition
The present disclose generally relates to wireless communication. In some aspects, a user equipment (UE) may receive information configuring a first search space (SS) set and a second SS set, wherein the first SS set is linked with the second SS set for physical downlink control channel (PDCCH) repetition, and wherein the first SS set is a recovery search space identifier configured SS set. The UE may monitor for a first one or more PDCCH candidates in the first SS set and a second one or more PDCCH candidates in the second SS set, wherein the first one or more PDCCH candidates and the second one or more PDCCH candidates are occurrences of a beam failure recovery response downlink control information (DCI).

receive, in a recovery search space identifier message, configuration information identifying a configuration of a first search space (SS) set, wherein the first SS set is configured for beam failure recovery monitoring;
monitor, in a first monitoring occasion, for first downlink control information (DCI) associated with a beam failure recovery response in the first SS set without monitoring for repetition, wherein the first SS set is not linked with another SS set;
receive, in the first monitoring occasion, the first downlink control information (DCI) associated with the beam failure recovery response;
monitor, in a second monitoring occasion, for a second SS set, wherein the first SS set is not linked to the second SS set; and
receive, in the second monitoring occasion, second DCI associated with the second SS set.

11 . The method of claim 7 ,
wherein the second SS set is linked to a third SS set for physical downlink control channel repetition.
12 . The method of claim 7 ,
wherein the first SS set is a recovery search space identifier configured SS set.
13 . A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
receive, in a recovery search space identifier message, configuration information identifying a configuration of a first search space (SS) set, wherein the first SS set is configured for beam failure recovery monitoring;
monitor, in a first monitoring occasion, for first downlink control information DCI) associated with a beam failure recovery response in the first SS set without monitoring for repetition, wherein the first SS set is not linked with another SS set;
