Title:

METHODS AND APPARATUSES FOR SIDELINK BEAM MANAGEMENT

Document Type and Number:

WIPO Patent Application WO/2023/197120

Kind Code:

A1

Abstract:

Embodiments of the present disclosure relate to methods and apparatuses for sidelink (SL) beam management. According to an embodiment of the present disclosure, a user equipment (UE) can include: a processor configured to: obtain configuration information for beam pairing based on configuration or pre-configuration, wherein the configuration information includes at least one of: a configuration for sidelink beam pairing block (S-BPB); a configuration for sidelink beam pairing reference signal (sl-BP-RS); a configuration for sidelink beam pairing feedback (sl-BP-FB); or association pattern (s) between occasions for sl-BP-RS and sl-BP-FB; and determine resource (s) for transmitting sl-BP-RS (s) based on the obtained configuration information in response to the UE becoming a UE for transmitting sl-BP-RS (s); a transmitter coupled to the processor and configured to: transmit the sl-BP-RS (s) on the determined resource (s); and a receiver coupled to the processor and configured to: receive sl-BP-FB (s) based on the obtained configuration information and the sl-BP-RS (s); wherein the processor is further configured to identify beam (s) of the UE based on the sl-BP-FB (s).
