Patent ID: 11889443
Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 13:
14. A first device configured to perform wireless communication, the first device comprising:
one or more memories storing instructions;
one or more transceivers; and
one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
obtain information related to a sidelink (SL) bandwidth part (BWP);
obtain SL synchronization priority order information which is set to Global Navigation Satellite Systems (GNSS)-based synchronization;
obtain information representing whether or not base station (BS)-related synchronization references are disabled to be selected;
detect a synchronization signal transmitted through the SL BWP by GNSS-related synchronization references or other user equipments (UEs), based on the information representing that the BS-related synchronization references are disabled to be selected; and
perform synchronization with one synchronization reference, based on the synchronization signal, among the GNSS-related synchronization references or the other UEs,
wherein, based on the SL synchronization priority order information set to the GNSS-based synchronization, synchronization references include the GNSS-related synchronization references, the BS-related synchronization references, and the other UEs,
wherein the GNSS-related synchronization references include a UE directly synchronized with a GNSS, and a UE indirectly synchronized with the GNSS, and
wherein the BS-related synchronization references include a BS, a UE directly synchronized with the BS, and a UE indirectly synchronized with the BS.
