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

Claim 6:
7. A first device for performing sidelink communication, comprising:
at least one transceiver;
at least one memory; and
at least one processor operatively coupled to the at least one transceiver and the at least one memory,
wherein the at least one memory stores instructions that, based on being executed by the at least one processor, perform operations comprising:
reserving transmission resources including a first sidelink (SL) resource based on a first priority value;
obtaining a medium access control (MAC) protocol data unit (PDU) that can be transmitted through the first SL resource, wherein the MAC PDU is related to a second priority value;
determining a pre-emption of the first SL resource based on the second priority value;
selecting a second SL resource different from the first SL resource based on the pre-emption of the first SL resource; and
transmitting the MAC PDU to a second device through the second SL resource,
wherein the determining of the pre-emption of the first SL resource comprises:
determining a candidate resource set for resource reselection;
determining whether the first SL resource is excluded from the candidate resource set based on the second priority value; and
determining a pre-emption of the first SL resource based on a determination that the first SL resource is excluded from the candidate resource set,
wherein the second SL resource is selected from the candidate resource set.
