Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit, to a network entity, a first signal including a request to update a resolution of a phase shifting operation associated with beam-based communications. The UE may receive, from the network entity, a second signal approving the request. The UE may communicate using a beam according to an updated resolution of the phase shifting operation based on the second signal approving the request. Additionally, or alternatively, the UE may transmit a first signal including a request to suspend a beam refinement process based on the resolution of the phase shifting operation. The UE may receive a second signal approving the request to suspend the beam refinement process. The UE may communicate with the network entity using a beam based on suspending further beam refinement in response to the second signal.

A first wireless device may transmit, to a second wireless device, capability control signaling indicating a first quantity of beam switches is supported within a first time period for a first antenna subarray, a first antenna module, or both, of the first wireless device. The first wireless device may receive from the second wireless device in accordance with the capability control signaling, a grant scheduling one or more messages and indicating a set of beams of the first wireless device over which to communicate the one or more messages in respective transmission time intervals (TTIs) of the first time period. The first wireless device may then transmit or receive, over the first time period using the first antenna subarray, the first antenna module, or both, the one or more messages using the set of beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information indicating a set of component carriers (CCs) associated with the UE. The UE may receive, from the base station, a message that activates or deactivates one or more CCs of the set of CCs. The UE may communicate, with the base station, after receiving the message, using one or more activated CCs of the set of CCs over a tuned radio frequency (RF) bandwidth that is based on receiving the message and based on the one or more activated CCs. Numerous other aspects are provided.
