Abstract

The present disclosure relates to wireless communication methods and apparatuses. In one example method, a first device determines a positioning manner based on a positioning requirement on a first terminal device and a second terminal device, where the positioning manner includes at least one of the following manners: performing positioning through a first interface between the first terminal device and a corresponding access network device, performing positioning through a second interface between the second terminal device and a corresponding access network device, or performing positioning through a third interface between the first terminal device and the second terminal device. The first device sends first information according to the positioning manner, where the first information is used to perform positioning in the positioning manner.

First claim

1 . A wireless communication method, wherein the method comprises:
determining, by a first device, a positioning manner based on a positioning requirement on a first terminal device and a second terminal device, wherein the positioning manner comprises at least one of the following manners: performing positioning through a first interface between the first terminal device and a corresponding access network device; performing positioning through a second interface between the second terminal device and a corresponding access network device; or performing positioning through a third interface between the first terminal device and the second terminal device; and sending, by the first device, first information according to the positioning manner, wherein the first information is used to perform positioning in the positioning manner.

2 . The method according to claim 1 , wherein the positioning requirement comprises obtaining at least one of the following position information: first position information of the first terminal device, second position information of the second terminal device, relative position information between the first terminal device and the second terminal device, relative distance information between the first terminal device and the second terminal device, or relative angle information between the first terminal device and the second terminal device.

3 . The method according to claim 1 , wherein the determining, by a first device, a positioning manner based on a positioning requirement comprises:
determining, by the first device, the positioning manner based on first capability information, second capability information, and the positioning requirement, wherein: the first capability information indicates at least one of the following information: at least one positioning manner supported by the first terminal device, location precision corresponding to each of the at least one positioning manner supported by the first terminal device, a location algorithm corresponding to each of the at least one positioning manner supported by the first terminal device, a latency corresponding to each of the at least one positioning manner supported by the first terminal device, a type of an interface between the first terminal device and the second terminal device, a discovery mode supported by the first terminal device, or a communication capability of the interface between the first terminal device and the second terminal device; and the second capability information indicates at least one of the following information: at least one positioning manner supported by the second terminal device, location precision corresponding to each of the at least one positioning manner supported by the second terminal device, a location algorithm corresponding to each of the at least one positioning manner supported by the second terminal device, a latency corresponding to each of the at least one positioning manner supported by the second terminal device, the type of the interface between the second terminal device and the first terminal device, a discovery mode supported by the second terminal device, or the communication capability of the interface between the first terminal device and the second terminal device.

4 . The method according to claim 3 , wherein before the determining, by a first device, a positioning manner, the method further comprises:
sending, by the first device, a query message, wherein the query message is used to request at least one of the first capability information or the second capability information; and receiving, by the first device, the at least one of the first capability information or the second capability information in response to the query message.

5 . The method according to claim 2 , wherein the positioning manner is performing positioning through the third interface, the positioning requirement comprises at least one of the following: the relative position information, the relative distance information, or the relative angle information, and the method further comprises:
when the positioning performed through the third interface fails, determining, by the first device, that the positioning manner is performing positioning through the first interface and performing, by the first device, positioning through the second interface.

6 . The method according to claim 3 , wherein the positioning requirement further comprises at least one of the following information: a precision requirement, a latency requirement, or a quality of service (QOS) level requirement, and the method further comprises:
receiving, by the first device, a location request message from a second device, wherein the location request message comprises at least one of the following information: the positioning requirement, identification information of the first terminal device, identification information of the second terminal device, the first capability information, the second capability information, a location service identifier, trigger condition information, or action information, wherein the location service identifier indicates a service that requests the position information, wherein the trigger condition information indicates at least one of the first terminal device or the second terminal device to perform a first action when the position information meets a first condition, and wherein the action information indicates the first action.

7 . The method according to claim 1 , wherein the first device is a third terminal device, and the sending, by the first device, first information according to the positioning manner comprises:
sending, by the first device, the first information to at least one of the first terminal device or the second terminal device according to the positioning manner; or sending, by the first device, the first information to a location management network element according to the positioning manner.

8 . The method according to claim 1 , wherein the first device is a location management network element, and the sending, by the first device, first information according to the positioning manner comprises:
sending, by the first device, the first information to at least one of the first terminal device or the second terminal device according to the positioning manner.

9 . The method according to claim 1 , wherein the first device is the first terminal device, and the sending, by the first device, first information according to the positioning manner comprises:
sending, by the first device, the first information to the second terminal device; or sending, by the first device, the first information to a location management network element.

10 . The method according to claim 2 , wherein the method further comprises:
receiving, by the first device, the position information; receiving, by the first device, measurement information corresponding to the position information; or receiving, by the first device, measurement information corresponding to the position information, and determining, by the first device, the position information based on the measurement information.

11 . The method according to claim 10 , wherein the method further comprises:
sending, by the first device, the measurement information or the position information.

12 . A communication apparatus, comprising:
at least one of processor; and at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to enable the apparatus to perform operations comprising: determining a positioning manner based on a positioning requirement on a first terminal device and a second terminal device, wherein the p
