Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of a beam switching capability of the UE that is based at least in part on an antenna subarray from an antenna array of the UE, and communicate, with the base station, using the antenna subarray in accordance with the beam switching capability of the UE, based at least in part on the indication of the beam switching capability of the UE. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- transmitting, to a base station, an indication of a beam switching capability of the UE that is based on an antenna subarray from an antenna array of the UE,
- the antenna subarray being determined based on an architectural constraint of the UE associated with a radio frequency design or a circuit design of the UE, and
- the beam switching capability indicating a maximum number of beam switches that the UE is capable of performing per slot;
- and
- communicating, with the base station, using the antenna subarray in accordance with the beam switching capability of the UE, based on the indication of the beam switching capability of the UE.
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 processors individually or collectively configured to:
- transmit, to a base station, an indication of a beam switching capability of the UE that is based on an antenna subarray from an antenna array of the UE,
- the antenna subarray being determined based on an architectural constraint of the UE associated with a radio frequency design or a circuit design of the UE, and
- the beam switching capability indicating a maximum number of beam switches that the UE is capable of performing per slot;
- and
- communicate, with the base station, using the antenna subarray in accordance with the beam switching capability of the UE, based on the indication of the beam switching capability of the UE.
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:
- transmit, to a base station, an indication of a beam switching capability of the UE that is based on an antenna subarray from an antenna array of the UE,
- the antenna subarray being determined based on an architectural constraint of the UE associated with a radio frequency design or a circuit design of the UE, and
- the beam switching capability indicating a maximum number of beam switches that the UE is capable of performing per slot;
- and
- communicate, with the base station, using the antenna subarray in accordance with the beam switching capability of the UE, based on the indication of the beam switching capability of the UE.
An apparatus for wireless communication, comprising:
- means for transmitting, to a base station, an indication of a beam switching capability of the apparatus that is based on an antenna subarray from an antenna array of the apparatus,
- the antenna subarray being determined based on an architectural constraint of the apparatus associated with a radio frequency design or a circuit design of the apparatus, and
- the beam switching capability indicating a maximum number of beam switches that the apparatus is capable of performing per slot;
- and
- means for communicating, with the base station, using the antenna subarray in accordance with the beam switching capability of the apparatus, based on the indication of the beam switching capability of the apparatus.
