Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect beam failure for a first beam group in a cell including the first beam group and a second beam group. The UE may selectively transmit a beam failure recovery request for the first beam group based at least in part on a determination of uplink resource availability in the second beam group. Numerous other aspects are described.
Claims20
An apparatus for wireless communication at a user equipment (UE), comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, which, individually or in any combination, are operable to cause the apparatus to:
- receive configuration information that configures one or more scheduling request resources for per beam failure detection (BFD) reference signal set beam failure recovery scheduling requests;
- detect beam failure on a BFD reference signal set of a cell;
- and
- transmit, using a physical uplink control channel (PUCCH) scheduling request resource for beam failure recovery for the BFD reference signal set, a beam failure recovery scheduling request for the BFD reference signal set based at least in part on the configuration information.
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving configuration information that configures one or more scheduling request resources for per beam failure detection (BFD) reference signal set beam failure recovery scheduling requests;
- detecting beam failure on a BFD reference signal set of a cell;
- and
- transmitting, using a physical uplink control channel (PUCCH) scheduling request resource for beam failure recovery for the BFD reference signal set, a beam failure recovery scheduling request for the BFD reference signal set based at least in part on the configuration information.
A non-transitory computer-readable medium storing a set of instructions for wireless communication, 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 configuration information that configures one or more scheduling request resources for per beam failure detection (BFD) reference signal set beam failure recovery scheduling requests;
- detect beam failure on a BFD reference signal set of a cell;
- and
- transmit, using a physical uplink control channel (PUCCH) scheduling request resource for beam failure recovery for the BFD reference signal set, a beam failure recovery scheduling request for the BFD reference signal set based at least in part on the configuration information.
