Abstract
Method of resource selection where a selection window with a total number of resources is set. The method includes setting a sensing window and monitoring slots by decoding a physical sidelink control channel (PSCCH) and measuring a reference signal received power (RSRP), setting a threshold, excluding any restricted resources from the total number of resources, excluding any occupied resources from the total number of resources, and determining if an initial number of remaining resources is greater than or equal to an initial percentage of the total number of resources.
Claims20
A method comprising:
- measuring, by a user equipment (UE), a reference signal received power (RSRP) of one or more slots;
- determining, by the UE, that the RSRP is greater than a threshold and, in response to determining that the RSRP is greater than the threshold, excluding one or more resources from a total number of resources associated with a selection window;
- determining, by the UE, whether a number of remaining resources, after excluding the one or more resources from the total number of resources, is smaller than a percentage of the total number of resources, wherein the percentage is selected from a preconfigured set, based on a traffic priority;
- and
- performing, by the UE, one of:
- increasing the threshold if the number of remaining resources is smaller than the percentage of the total number of resources;
- or
- reporting the remaining resources to a higher layer if the number of remaining resources is not smaller than the percentage of the total number of resources.
A user equipment (UE) device configured to:
- measure a reference signal received power (RSRP) of one or more slots;
- determine whether the RSRP is greater than a threshold;
- exclude one or more resources from a total number of resources associated with a selection window if the RSRP is greater than the threshold;
- determine whether a number of remaining resources is smaller than a percentage of the total number of resources, wherein the percentage is selected from a preconfigured set, based on a traffic priority;
- increase the threshold if the number of remaining resources is smaller than the percentage of the total number of resources;
- report the remaining resources to a higher layer if the number of remaining resources is not smaller than the percentage of the total number of resources.
