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.
Claims30
A user equipment (UE) for wireless communication, comprising:
- memory;
- one or more processors coupled to the memory;
- and
- instructions stored in the memory and operable, when executed by the one or more processors, to cause the UE to:
- receive configuration information that configures one or more scheduling request resources dedicated to per beam group beam failure recovery scheduling requests;
- detect beam failure for a first beam group in a cell including the first beam group and a second beam group;
- and
- transmit a beam failure recovery request for the first beam group based at least in part on the configuration information and a determination of uplink resource availability in the second beam group, wherein:
- the beam failure recovery request includes a beam failure recovery scheduling request, and
- the beam failure recovery scheduling request is transmitted on a beam of the second beam group using a physical uplink control channel (PUCCH) scheduling request resource dedicated to beam failure recovery for the first beam group.
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving configuration information that configures one or more scheduling request resources dedicated to per beam group beam failure recovery scheduling requests;
- detecting beam failure for a first beam group in a cell including the first beam group and a second beam group;
- and
- transmitting a beam failure recovery request for the first beam group based at least in part on the configuration information and a determination of uplink resource availability in the second beam group, wherein:
- the beam failure recovery request includes a beam failure recovery scheduling request, and
- the beam failure recovery scheduling request is transmitted on a beam of the second beam group using a physical uplink control channel (PUCCH) scheduling request resource dedicated to beam failure recovery for the first beam group.
A non-transitory computer-readable medium storing one or more instructions for wireless communication 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 dedicated to per beam group beam failure recovery scheduling requests;
- detect beam failure for a first beam group in a cell including the first beam group and a second beam group;
- and
- transmit a beam failure recovery request for the first beam group based at least in part on the configuration information and a determination of uplink resource availability in the second beam group, wherein:
- the beam failure recovery request includes a beam failure recovery scheduling request, and
- the beam failure recovery scheduling request is transmitted on a beam of the second beam group using a physical uplink control channel (PUCCH) scheduling request resource dedicated to beam failure recovery for the first beam group.
An apparatus for wireless communication, comprising:
- means for receiving configuration information that configures one or more scheduling request resources dedicated to per beam group beam failure recovery scheduling requests;
- means for detecting beam failure for a first beam group in a cell including the first beam group and a second beam group;
- and
- means for transmitting a beam failure recovery request for the first beam group based at least in part on the configuration information and a determination of uplink resource availability in the second beam group, wherein:
- the beam failure recovery request includes a beam failure recovery scheduling request, and
- the beam failure recovery scheduling request is transmitted on a beam of the second beam group using a physical uplink control channel (PUCCH) scheduling request resource dedicated to beam failure recovery for the first beam group.
