Abstract

Claims (67)

1. A method of processing transmission power level information, performed by a first user equipment (UE), comprising:

determining transmission power level information based on a correspondence between transmission power levels and transmission power regions; and

sending the transmission power level information to a second UE, and

wherein said determining the transmission power level information based on the correspondence between transmission power levels and transmission power regions comprises at least one of:

in response to determining that the first UE and the second UE are synchronized through a base station, determining the transmission power level information based on the correspondence sent by the base station; or

in response to determining that the first UE and the second UE are synchronized through an object other than a base station, determining the transmission power level information based on the correspondence that is pre-configured.

2. The method of processing transmission power level information according to claim 1 , wherein said sending the transmission power level information to the second UE comprises:

sending, to the second UE, sidelink control information (SCI) carrying the transmission power level information.

3. The method of processing transmission power level information according to claim 1 , further comprising:

receiving the correspondence sent by the base station;

or,

obtaining the correspondence, wherein the correspondence is pre-configured.

4. The method of processing transmission power level information according to claim 1 , wherein said determining the transmission power level information based on the correspondence between transmission power levels and transmission power regions comprises:

obtaining the transmission power level information by querying the correspondence based on a transmission power at which the first UE transmits sidelink data.

5. A method of processing transmission power level information, being applicable to a second user equipment (UE), comprising:

receiving transmission power level information sent by a first UE;

determining a transmission power region corresponding to the transmission power level information based on a correspondence between transmission power levels and transmission power regions; and

determining, from the transmission power region, a first transmission power of first sidelink data transmitted from the first UE, and

wherein said determining the transmission power region corresponding to the transmission power level information based on the correspondence between transmission power levels and transmission power regions comprises at least one of:

in response to determining that the first UE and the second UE are synchronized through a base station, determining the transmission power region corresponding to the transmission power level information based on the correspondence sent by the base station; or

in response to determining that the first UE and the second UE are synchronized through an object other than the base station, determining the transmission power region corresponding to the transmission power level information based on the correspondence that is pre-configured.

6. The method of processing transmission power level information according to claim 5 , wherein said receiving the transmission power level information sent by the first UE comprises:

receiving sidelink control information (SCI) sent by the first UE, wherein the transmission power level information is carried in the SCI.

7. The method of processing transmission power level information according to claim 5 , further comprising:

after receiving the transmission power level information, measuring a sidelink channel to obtain a reference signal receiving power (RSRP) of the sidelink channel; and

determining a path loss of the sidelink channel based on the RSRP and the first transmission power of the first sidelink data transmitted from the first UE.

8. The method of processing transmission power level information according to claim 7 , further comprising:

controlling, based on the path loss, a second transmission power at which second sidelink data is transmitted to the first UE.

9. The method of processing transmission power level information according to claim 5 , further comprising:

receiving the correspondence between transmission power levels and transmission power regions which is sent by the base station;

or,

obtaining the correspondence between transmission power levels and transmission power regions which is pre-configured.

10. An apparatus for processing transmission power level information, comprising:

one or more processors; and

a memory for storing executable instructions for the one or more processors;

wherein the one or more processors are configured to implement, when executing the executable instructions, the method of processing transmission power level information according to claim 1 .

11. An apparatus for processing transmission power level information, comprising:

one or more processors; and

a memory for storing executable instructions for the one or more processors;

wherein the one or more processors are configured to:

receive transmission power level information sent by a first user equipment (UE);

determine a transmission power region corresponding to the transmission power level information based on a correspondence between transmission power levels and transmission power regions; and

determine, from the transmission power region, a first transmission power of first sidelink data transmitted from the first UE;

wherein the one or more processors are further configured to at least one of:

in response to determining that the first UE and a second UE are synchronized through a base station, determine the transmission power region corresponding to the transmission power level information based on the correspondence sent by the base station; or

in response to determining that the first UE and the second UE are synchronized through an object other than the base station, determine the transmission power region corresponding to the transmission power level information based on the correspondence that is pre-configured.

12. A non-transitory computer readable storage medium storing executable instructions therein, wherein when being executed by one or more processors, the executable instructions enable the one or more processors to perform the method of processing transmission power level information according to claim 1 .

13. A non-transitory computer readable storage medium storing executable instructions therein, wherein when being executed by one or more processors, the executable instructions enable the one or more processors to perform the method of processing transmission power level information according to claim 5 .

14. The apparatus for processing transmission power level information according to claim 10 , wherein the one or more processors are further configured to:

send, to the second UE, sidelink control information (SCI) carrying the transmission power level information.

15. The apparatus for processing transmission power level information according to claim 10 , wherein the one or more processors are further configured to:

receive the correspondence sent by the base station;

or,
