Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, based at least in part on at least one of a plurality of conditions being met, to switch from a static analog beamforming codebook to a dynamic analog beamforming beam weight calculation for selecting beam weights for communications between the UE and a base station. The UE may select the beam weights for the communications using the dynamic beam weight calculation. The UE may communicate, using the beam weights, with the base station. Numerous other aspects are described.
Claims30
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- determine, based at least in part on at least one of a plurality of conditions being met, to switch from using a static analog beamforming codebook to using a dynamic analog beam weight calculation for selecting beam weights for communications between the UE and a network entity;
- select the beam weights for the communications using the dynamic analog beam weight calculation;
- and
- communicate, using the beam weights, with the network entity.
A network entity for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- transmit, to a user equipment (UE), configuration information indicating that the UE is to switch, based at least in part on at least one of a plurality of conditions being met, from using a static analog beamforming codebook to using a dynamic analog beam weight calculation for selecting beam weights for communications between the UE and the network entity;
- receive, from the UE, a request for one or more reference signals associated with the dynamic analog beam weight calculation;
- and
- transmit, to the UE, the one or more reference signals.
A method of wireless communication performed by a user equipment (UE), comprising:
- determining, based at least in part on at least one of a plurality of conditions being met, to switch from using a static analog beamforming codebook to using a dynamic analog beamforming beam weight calculation for selecting beam weights for communications between the UE and a network entity;
- selecting the beam weights for the communications using the dynamic analog beam weight calculation;
- and
- communicating, using the beam weights, with the network entity.
