Claim 9:
10. An apparatus for controlling a first device, comprising:
at least one memory; and
at least one processor operatively coupled to the at least one memory and storing 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.
