Abstract

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).

First claim

What is claimed is:

1 . A user equipment (UE) for wireless communication, comprising:
one or more memories; and one or more processors coupled to the one or more memories, the one or more memories comprising instructions configurable to be executed by the one or more processors to 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;
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.

2 . The UE of claim 1 ,
wherein the first SS set is disabled for physical downlink control channel repetition.

3 . The UE of claim 1 ,
wherein the second SS set is not linked with the first SS set based at least in part on the recovery search space identifier message conveying the configuration of the first SS set.

4 . The UE of claim 1 ,
wherein the second SS set is not linked to the first SS set for physical downlink control channel repetition.

5 . The UE of claim 1 ,
wherein the second SS set is linked to a third SS set for physical downlink control channel repetition.

6 . The UE of claim 1 ,
wherein the first SS set is a recovery search space identifier configured SS set.

7 . A method of wireless communication performed by a user equipment (UE), comprising:
receiving, 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; monitoring, 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; receiving, in the first monitoring occasion, the first downlink control information (DCI) associated with the beam failure recovery response; monitoring, in a second monitoring occasion, for a second SS set, wherein the first SS set is not linked to the second SS set; and receiving, in the second monitoring occasion, second DCI associated with the second SS set.

8 . The method of claim 7 ,
wherein the first SS set is disabled for physical downlink control channel repetition.

9 . The method of claim 7 ,
wherein the second SS set is not linked with the first SS set based at least in part on the recovery search space identifier message conveying the configuration of the first SS set.

10 . The method of claim 7 ,
wherein the second SS set is not linked to the first SS set for physical downlink control channel repetition.

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;
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.

14 . The non-transitory computer-readable medium of claim 13 ,
wherein the first SS set is disabled for physical downlink control channel repetition.

15 . The non-transitory computer-readable medium of claim 13 ,
wherein the second SS set is not linked with the first SS set based at least in part on the recovery search space identifier message conveying the configuration of the first SS set.

16 . The non-transitory computer-readable medium of claim 13 ,
wherein the second SS set is not linked to the first SS set for physical downlink control channel repetition.

17 . The non-transitory computer-readable medium of claim 13 ,
wherein the second SS set is linked to a third SS set for physical downlink control channel repetition.

18 . The non-transitory computer-readable medium of claim 13 ,
wherein the first SS set is a recovery search space identifier configured SS set.

19 . An apparatus, comprising:
means for receiving, 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; means for monitoring, 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; means for receiving, in the first monitoring occasion, the first downlink control information (DCI) associated with the beam failure recovery response; means for monitoring, in a second monitoring occasion, for a second SS set, wherein the first SS set is not linked to the second SS set; and means for receiving, in the second monitoring occasion, second DCI associated with the second SS set.

20 . The apparatus of claim 19 ,
wherein the first SS set is disabled for physical downlink control channel repetition.

21 . The apparatus of claim 19 ,
wherein the second SS set is not linked with the first SS set based at least in part on the recovery search space identifier message conveying the configuration of the first SS set.

22 . The apparatus of claim 19 ,
wherein the second SS set is not linked to the first SS set for physical downlink control channel repetition.

23 . The apparatus of claim 19 ,
wherein the second SS set is linked to a third SS set for physical downlink control channel repetition.

24 . The apparatus of claim 19 ,
wherein the first SS set is a recovery search space identifier configured SS set.
