Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure a medium access control control element (MAC-CE) to indicate beam failure information for one or more serving cells, wherein the beam failure information is associated with at least one of a first transmit-receive point (TRP) or a second TRP of the one or more serving cells. The UE may transmit the MAC-CE to a base station via at least one serving cell. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- configuring a medium access control control element (MAC-CE) to indicate beam failure information for one or more serving cells, the MAC-CE comprising:
- a first set of one or more bits indicating whether a beam failure has occurred on the one or more serving cells;
- a second set of one or more bits indicating whether a subsequent set of bits indicates a single new beam or multiple new beams;
- and
- a third set of one or more bits indicating whether the single new beam or the multiple new beams is associated with a first transmit-receive point (TRP) or a second TRP;
- and
- transmitting the MAC-CE to a base station via at least one serving cell.
A method of wireless communication performed by a base station, comprising:
- receiving a medium access control control element (MAC-CE) to indicate beam failure information for one or more serving cells, the MAC-CE comprising:
- a first set of one or more bits indicating whether a beam failure has occurred on the one or more serving cells;
- a second set of one or more bits indicating whether a subsequent set of bits indicates a single new beam or multiple new beams;
- and
- a third set of one or more bits indicating whether the single new beam or the multiple new beams is associated with a first transmit-receive point (TRP) or a second TRP;
- and
- performing a beam failure recovery operation based at least in part on the beam failure information.
A user equipment (UE) for wireless communication, comprising:
- one or more memories;
- one or more processors coupled to the one or more memories;
- and
- instructions stored in the one or more memories and operable, when executed by the one or more processors, to cause the UE to:
- configure a medium access control control element (MAC-CE) to indicate beam failure information for one or more serving cells, the MAC-CE comprising:
- a first set of one or more bits indicating whether a beam failure has occurred on the one or more serving cells;
- a second set of one or more bits indicating whether a subsequent set of bits indicates a single new beam or multiple new beams;
- and
- a third set of one or more bits indicating whether the single new beam or the multiple new beams is associated with a first transmit-receive point (TRP) or a second TRP;
- and
- transmit the MAC-CE to a base station via at least one serving cell.
A base station for wireless communication, comprising:
- one or more memories;
- one or more processors coupled to the one or more memories;
- and
- instructions stored in the one or more memories and operable, when executed by the one or more processors, to cause the base station to:
- receive a medium access control control element (MAC-CE) to indicate beam failure information for one or more serving cells, the MAC-CE comprising:
- a first set of one or more bits indicating whether a beam failure has occurred on the one or more serving cells;
- a second set of one or more bits indicating whether a subsequent set of bits indicates a single new beam or multiple new beams;
- and
- a third set of one or more bits indicating whether the single new beam or the multiple new beams is associated with a first transmit-receive point (TRP) or a second TRP;
- and
- perform a beam failure recovery operation based at least in part on the beam failure information.
