Abstract
A method for determining a reference resource includes: a first terminal determines a resource pool where a reference resource set is located, and determines, in a resource selection window, a first resource set belonging to the resource pool; the first terminal excludes resources from the first resource set based on detected Sidelink Control Information (SCI) and a measured Sidelink Reference Signal Received Power (SL-RSRP) to obtain a second resource set, where the second resource set is a resource set adaptable to be used by a second terminal; and the first terminal indicates the second resource set to the second terminal.
Claims18
A method for determining a reference resource, comprising:
- determining, by a first terminal, a resource pool where a reference resource set is located, and determining, in a resource selection window, a first resource set belonging to the resource pool;
- excluding, by the first terminal, resources from the first resource set based on detected Sidelink Control Information (SCI) and a measured Sidelink Reference Signal Received Power (SL-RSRP) to obtain a second resource set, wherein the second resource set is a resource set adaptable to be used by a second terminal;
- and
- indicating, by the first terminal, the second resource set to the second terminal,
- wherein the method further comprises:
- determining, by the first terminal, at least one SL-RSRP threshold, wherein the at least one SL-RSRP threshold is used by the first terminal to exclude the resources,
- wherein determining, by the first terminal, the at least one SL-RSRP threshold comprises:
- determining, by the first terminal, a first SL-RSRP threshold based on a first parameter and a second parameter,
- wherein the first parameter is a priority of data to be sent by the second terminal, and the second parameter is a priority indicated in SCI received by the first terminal,
- wherein excluding, by the first terminal, the resources from the first resource set based on the detected SCI and the measured SL-RSRP to obtain the second resource set comprises:
- a first step that the first terminal performs a first exclusion operation on the first resource set;
- a second step that the first terminal performs a second exclusion operation on the first resource set;
- and
- a third step that the first terminal performs a third exclusion operation on the first resource set based on the first SL-RSRP threshold, the detected SCI and the measured SL-RSRP,
- wherein after the first step, the second step and the third step are performed, a set of remaining resources is a second resource set.

A first terminal, comprising:
- a processor, and a memory configured to store computer instructions executable by the processor,
- wherein the processor is configured to perform operations of:
- determining a resource pool where a reference resource set is located, and determine, in a resource selection window, a first resource set belonging to the resource pool;
- excluding resources from the first resource set based on detected Sidelink Control Information (SCI) and a measured Sidelink Reference Signal Received Power (SL-RSRP) to obtain a second resource set, wherein the second resource set is a resource set adaptable to be used by a second terminal;

- a first step that the first terminal performs a first exclusion operation on the first resource set;
- a second step that the first terminal performs a second exclusion operation on the first resource set;
- and
- a third step that the first terminal performs a third exclusion operation on the first resource set based on the first SL-RSRP threshold, the detected SCI and the measured SL-RSRP,
- wherein after the first step, the second step and the third step are performed, a set of remaining resources is a second resource set.
