Title:
METHOD AND APPARATUS FOR A RESOURCE RE-EVALUATION OR PRE-EMPTION CHECKING PROCEDURE
Document Type and Number:
WIPO Patent Application WO/2024/026716
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to methods and apparatuses of a channel occupancy time (COT) sharing mechanism for a sidelink groupcast. According to some embodiments of the disclosure, a user equipment (UE) may include a transceiver; and a processor coupled to the transceiver. The processor may be configured to: perform a resource re-evaluation procedure or a pre-emption checking procedure to determine whether a candidate resource within a set of candidate resources for the UE is available, wherein the candidate resource is selected or reserved by the UE for a sidelink transmission on an unlicensed spectrum; and in response to determining that the candidate resource is unavailable, exclude the candidate resource from the set of candidate resources.
