Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine to switch from a first beamforming mode to a second beamforming mode, wherein one of the first beamforming mode and the second beamforming mode is a digital beamforming mode, and wherein the other of the first beamforming mode and the second beamforming mode is an at least partially analog beamforming mode; and perform a communication using the second beamforming mode. Numerous other aspects are provided.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive a request to switch from a first beamforming mode to a second beamforming mode, wherein one of the first beamforming mode and the second beamforming mode is a digital beamforming mode, and wherein the other of the first beamforming mode and the second beamforming mode is a hybrid beamforming mode or an analog beamforming mode;
- and
- perform a communication using the second beamforming mode.
An apparatus for wireless communication at a base station, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- transmit a request to a user equipment (UE) indicating to switch from a first beamforming mode to a second beamforming mode, wherein one of the first beamforming mode and the second beamforming mode is a digital beamforming mode, and wherein the other of the first beamforming mode and the second beamforming mode is an analog beamforming mode or a hybrid beamforming mode;
- and
- transmit, to the UE, configuration information configuring the UE to switch from the first beamforming mode to the second beamforming mode.
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving a request to switch from a first beamforming mode to a second beamforming mode, wherein one of the first beamforming mode and the second beamforming mode is a digital beamforming mode, and wherein the other of the first beamforming mode and the second beamforming mode is a hybrid beamforming mode or an analog beamforming mode;
- and
- performing a communication using the second beamforming mode.
A method of wireless communication performed by a base station, comprising:
- transmitting a request to a user equipment (UE) indicating to switch from a first beamforming mode to a second beamforming mode, wherein one of the first beamforming mode and the second beamforming mode is a digital beamforming mode, and wherein the other of the first beamforming mode and the second beamforming mode is an analog beamforming mode or a hybrid beamforming mode;
- and
- transmitting, to the UE, configuration information configuring the UE to switch from the first beamforming mode to the second beamforming mode.
