CONFIGURATION OF BEAM FAILURE RECOVERY SEARCH SPACE SET FOR PHYSICAL DOWNLINK CONTROL CHANNEL REPETITION
Various aspects of the present disclosure generally relate 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).

8 . The UE of claim 6 , wherein a beam failure recovery identified beam is applied to the first one or more PDCCH candidates in the first SS set and not the second one or more PDCCH candidates in the second SS set.
9 . The UE of claim 6 , wherein a first beam failure recovery identified beam is applied to the first one or more PDCCH candidates in the first SS set and a second beam failure recovery identified beam is applied to the second one or more PDCCH candidates in the second SS set, and wherein the first beam failure recovery identified beam is different from the second beam failure recovery identified beam.
10 . The UE of claim 1 , wherein a quantity of indicated beam failure recovery identified beams is based at least in part on a quantity of beams associated with a physical random access channel communication.
11 . The UE of claim 1 , wherein a quantity of indicated beam failure recovery identified beams is based at least in part on a quantity of physical random access channel communications that are configured.
12 . The UE of claim 8 , wherein the memory further comprises instructions executable by the one or more processors to cause the UE to:
receive a physical downlink shared channel using a quasi-co-location parameter associated with the first one or more PDCCH candidates in the first SS set.
13 . The UE of claim 1 , wherein the memory further comprises instructions executable by the one or more processors to cause the UE to:
receive a physical downlink shared channel using quasi-co-location parameters associated with the first one or more PDCCH candidates in the first SS set and the second one or more PDCCH candidates in the second SS set.
14 . A method of wireless communication performed by a user equipment (UE), comprising:
receiving 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; and
monitoring 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).
15 . The method of claim 14 , wherein the first SS set and the second SS set are associated with a common control resource set (CORESET).
16 . The method of claim 15 , wherein the first one or more PDCCH candidates and the second one or more PDCCH candidates are associated with a common quasi-co-location (QCL) parameter.
17 . The method of claim 15 , wherein a quasi-co-location (QCL) parameter of the common CORESET is based at least in part on a corresponding QCL parameter of a reference signal associated with a new identified beam after beam failure recovery detection.
