Abstract
Proposed is a method for operating a first device (100) in a wireless communication system. The method may comprise the steps of: triggering resource re-evaluation or pre-emption; and determining at least one second candidate slot for performing sensing related to the resource re-evaluation or the pre-emption, wherein the number of at least one first candidate slot related to an initial resource selection is greater than or equal to a first threshold, the number of the at least one second candidate slot is greater than or equal to a second threshold value, and the first threshold value is different from the second threshold value.
Claims14
A method comprising:
- obtaining a configuration related to a resource pool;
- triggering resource selection for an inter-user equipment (UE) physical control channel resource or an inter-UE physical shared channel resource for transmitting a medium access control (MAC) protocol data unit (PDU) to a second device, within the resource pool;
- determining at least one first candidate slot for first sensing related to the resource selection,
- wherein a number of the at least one first candidate slot is greater than or equal to a first threshold value;
- selecting a first inter-UE physical control channel resource or a first inter-UE physical shared channel resource for transmitting the MAC PDU, based on the first sensing;
- detecting a collision for the first inter-UE physical control channel resource or the first inter-UE physical shared channel resource;
- triggering resource re-evaluation or pre-emption based on the collision, after the resource selection;
- and
- determining at least one second candidate slot for performing second sensing related to the resource re-evaluation or the pre-emption,
- wherein a number of the at least one second candidate slot is greater than or equal to a second threshold value, and
- wherein the second threshold value is smaller than the first threshold value.
