Claims (15)

1. A user equipment, UE, comprising: a memory (1804G); and one or more processors (1803E) configured to, when executing instructions stored in the memory, cause the UE to: determine (1410) an initial candidate set including all candidate consecutive slot resources in a resource selection window for an unlicensed spectrum sidelink, SL-U, transmission using consecutive slot resources; remove (1460) consecutive slot resources, from the initial candidate set, based on a reference signal received power, RSRP, threshold measured during a sensing window corresponding to the resource selection window; and report (1490), based on a number of consecutive slot resources of a consecutive slot SL transmission being less than a number of consecutive slot resources of the initial candidate set remaining in the resource selection window, the consecutive slot resources remaining in the resource selection window for higher layer processing, wherein the reporting is based on a single priority value associated with the consecutive slot resources for the SL-U transmissions.
2. The UE of claim 1, wherein the UE is to remove consecutive slot resources, from the initial candidate set, when the consecutive slot resources have not been monitored by the UE with a supported periodical extension.
3. The UE of claim 1, wherein the UE is to remove consecutive slot resources, from the initial candidate set, when the consecutive slot resources overlap with any single-slot resource reserved by another UE with an RSRP above the RSRP threshold.
4. The UE of claim 3, wherein the UE is to remove the consecutive slot resources, from the initial candidate set, when the consecutive slot resources overlap with any single-slot resource reserved by another UE and associated with a priority value satisfying certain criteria.
5. The UE of claim 1, wherein when the number of consecutive slot resources, of a consecutive slot SL transmission, is equal to or greater than the number of consecutive slot resources, of the initial candidate set, remaining in the resource selection window, increase the RSRP threshold and determine the number of consecutive slot resources, of the initial candidate set, remaining in the resource selection window based on the increased RSRP threshold.
6. The UE of claim 1, wherein a channel occupancy time, COT, for the consecutive slot SL transmission is not modified by reserved SL-U resources within the COT.
7. The UE of claim 1, wherein a total duration of a channel occupancy time for the consecutive slot SL transmission is extended by reserved SL-U resources within the COT.
8. The UE of claim 1, wherein a total duration of a channel occupancy time for the consecutive slot SL transmission is stopped by reserved SL-U resources within the COT.
9. A method, performed by a user equipment, UE, the method comprising: Determining (1410) an initial candidate set including all candidate consecutive slot resources in a resource selection window for an unlicensed spectrum sidelink, SL-U, transmission using consecutive slot resources; removing (1460) consecutive slot resources, from the initial candidate set, based on a reference signal received power, RSRP, threshold measured during a sensing window corresponding to the resource selection window; and reporting (1490), based on a number of consecutive slot resources of a consecutive slot SL transmission being less than a number of consecutive slot resources of the initial candidate set remaining in the resource selection window, the consecutive slot resources remaining in the resource selection window for higher layer processing, wherein the reporting is based on a single priority value associated with the consecutive slot resources for the SL-U transmission.
10. The method of claim 9, further comprising: removing consecutive slot resources, from the initial candidate set, when the consecutive slot resources have not been monitored by the UE with a supported periodical extension.
11. The method of claim 9, wherein the UE is to remove consecutive slot resources, from the initial candidate set, when the consecutive slot resources overlap with any single-slot resource reserved by another UE with an RSRP above the RSRP threshold.
12. The method of claim 11, wherein the UE is to remove the consecutive slot resources, from the initial candidate set, when the consecutive slot resources overlap with any single-slot resource reserved by another UE and associated with a priority value satisfying certain criteria.
13. The method of claim 9, wherein when the number of consecutive slot resources, of a consecutive slot SL transmission, is equal to or greater than the number of consecutive slot resources, of the initial candidate set, remaining in the resource selection window, increase the RSRP threshold and determine the number of consecutive slot resources, of the initial candidate set, remaining in the resource selection window based on the increased RSRP threshold.
14. The method of claim 9, wherein a total duration of a channel occupancy time, COT, for the consecutive slot SL transmission is not modified by reserved SL-U resources within the COT.
15. The method of claim 9, wherein a total duration of a channel occupancy time for the consecutive slot SL transmission is extended by reserved SL-U resources within the COT.
