Title:
BEAM APPLICATION TIME WITH BANDWIDTH PART SWITCHING IN WIRELESS COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2023/178642
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described that provide for determination of timing for application of a beam based on a beam switch indication and a switch of a bandwidth part (BWP) of a frequency bandwidth that is used for communications between a user equipment (UE) and a network entity. A UE may receive a beam switch indication to switch beamformed wireless communications from a first beam to a second beam. The UE may also determine that a BWP switch is to be performed prior to using the second beam, and may use the second beam and the new BWP based on a beam application time associated with the second beam, where the beam application time is based on a channel parameter (e.g., a sub-carrier spacing) of the first bandwidth part or the second bandwidth part.
