Title:
BEAM MANAGEMENT PROCEDURE FOR A USER EQUIPMENT GROUP
Document Type and Number:
WIPO Patent Application WO/2023/240519
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communication are described. In some examples, a user equipment (UE) may transmit, to a network entity, signaling including an indication of a group configuration for a UE group. The group configuration may include a group leader UE, one or more group member UEs, and an identifier mapping between the group leader UE and the one or more group member UEs. The group member UEs may be within a quasi co-location threshold of the group leader UE. The UE may perform a beam management procedure to measure multiple transmit beams and identify a transmit beam for communications between the network entity and the UE group. The UE may transmit the message indicating the transmit beam to the network entity. The methods, systems, and devices described herein may reduce beam management efforts for group member UEs, thus reducing power consumption and latency in beam management procedures.
