Abstract
A resource selection method, an apparatus, and a device, where the method includes determining, by first user equipment (UE), parameter information of a sensing window, where the parameter information includes at least one of a start time, a time span, or a quantity, sensing, by the first UE, the resource in the sensing window according to the parameter information of the sensing window, and selecting, by the first UE, a resource according to a sensing result.
Claims20
A resource selection method implemented by a user equipment (UE), wherein the resource selection method comprises:
- determining, according to a first resource reservation interval, parameter information of a sensing window, wherein the parameter information comprises a start time and/or a quantity of the sensing window, and wherein the first resource reservation interval is a time interval between reserved data transmission resources;
- performing, according to the parameter information, resource sensing in the sensing window;
- and
- selecting, according to a result of the resource sensing, a resource.
A resource selection method implemented by a base station, wherein the resource selection method comprises:
- determining one or more first resource reservation intervals, wherein each first resource reservation interval is a time interval between reserved data transmission resources;
- and
- sending, to a user equipment (UE), first indication information, wherein the first indication information indicates the one or more first resource reservation intervals, wherein the one or more first resource reservation intervals are configured to be used for the UE to determine parameter information of a sensing window, and wherein the parameter information comprises a start time and/or a quantity of the sensing window.
A resource selection method implemented by a base station, wherein the resource selection method comprises:
- determining a plurality of second resource reservation intervals, wherein the second resource reservation interval is a time interval between reserved data transmission resources;
- and
- sending, to a user equipment (UE), second indication information, wherein the second indication information indicates the plurality of second resource reservation intervals, wherein the plurality of second resource reservation intervals are configured to be used for the UE to determine one or more first resource reservation intervals, wherein the one or more first resource reservation intervals is a subset of the plurality of second resource reservation intervals, wherein the one or more first resource reservation intervals are configured to be used for the UE to determine parameter information of a sensing window, and wherein the parameter information comprises a start time and/or a quantity of the sensing window.
User equipment (UE), comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the UE to:
- determine, according to a first resource reservation interval, parameter information of a sensing window, wherein the parameter information comprises a start time and/or a quantity of the sensing window, and wherein the first resource reservation interval is a time interval between reserved data transmission resources;
- perform, according to the parameter information, resource sensing in the sensing window;
- and
- select, according to a result of the resource sensing, a resource.
A base station, comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the base station to:
- determine a plurality of second resource reservation intervals, wherein the second resource reservation interval is a time interval between reserved data transmission resources;
- and
- send, to a user equipment (UE), second indication information, wherein the second indication information indicates the plurality of second resource reservation intervals, wherein the plurality of second resource reservation intervals are configured to be used for the UE to determine one or more first resource reservation intervals, wherein the one or more first resource reservation intervals is a subset of the plurality of second resource reservation intervals, wherein the one or more first resource reservation intervals are configured to be used for the UE to determine parameter information of a sensing window, and wherein the parameter information comprises a start time and/or a quantity of the sensing window.
