Abstract

The present invention relates to the field of communications technologies, and provides a positioning method, a terminal, and a network device. The positioning method includes: obtaining positioning information, where the positioning information includes priority information related to a positioning signal, and/or measurement time information of a positioning signal; and determining the positioning signal based on the positioning information.

First claim

What is claimed is:

1. A positioning method, performed by a terminal and comprising:
obtaining positioning information, wherein the positioning information comprises priority information related to a positioning signal, and measurement time information of the positioning signal; and
determining the positioning signal based on the positioning information;
wherein the determining the positioning signal based on the positioning information comprises:
measuring a positioning reference signal (PRS) based on measurement time information in configuration information of the PRS and configuration information of a target priority of the PRS;
wherein, the priority information related to the positioning signal comprises a priority relation between the positioning signal and another signal or between the positioning signal and data service;
the method further comprises:
dropping low-priority data, in a case that the positioning signal overlaps the low-priority data.

2. The positioning method according to claim 1 , wherein before the obtaining positioning information, the method further comprises:
sending a positioning request, wherein the positioning request comprises a request for positioning the terminal, and/or a positioning assistance data request.

3. The positioning method according to claim 1 , wherein the positioning information comprises at least one of the following:
configuration information of a positioning signal with a target priority;
configuration information of a positioning signal configured based on a geographical location;
configuration information related to cancellation of repeated signal transmission;
configuration information related to cancellation of a measurement gap;
configuration information related to reduction of a quantity of measurements;
configuration information of a default positioning signal;
configuration information of a preconfigured positioning signal;
configuration information of an aperiodic positioning signal; and
measurement time information.

4. The positioning method according to claim 1 , wherein the measurement time information is configuration information of at least one measurement time window.

5. The positioning method according to claim 4 , wherein the configuration information of the at least one measurement time window further comprises start time information of the at least one measurement time window; and
the start time is determined based on following:
an offset relative to a system frame number or a slot number of a serving cell or base station.

6. The positioning method according to claim 4 , wherein the configuration information of the at least one measurement time window includes duration information of the at least one measurement time window.

7. The positioning method according to claim 1 , wherein the priority information related to the positioning signal comprises priority information of the positioning signal; and
a time-frequency resource corresponding to a positioning signal with a target priority satisfies at least one of the following conditions:
the time-frequency resource corresponding to the positioning signal with the target priority is allowed to be occupied by a data service whose priority is the target priority;
the time-frequency resource corresponding to the positioning signal with the target priority is not allowed to be occupied by a data service whose priority is lower than the target priority; and
the time-frequency resource corresponding to the positioning signal with the target priority is not allowed to be occupied by a signal whose priority is lower than the target priority.

8. The positioning method according to claim 1 , wherein the positioning information comprises configuration information of the positioning signal, and the configuration information of the positioning signal comprises at least one of the following:
a quantity of orthogonal frequency division multiplexing (OFDM) symbols of the positioning signal is 1 or 2; and
the positioning signal supports a cyclic shift greater than 12.

9. The positioning method according to claim 1 , wherein in a case in which the positioning information comprises the priority information related to the positioning signal, after validity of a positioning signal with a target priority expires, a default configuration or another configuration is restored.

10. The positioning method according to claim 1 , wherein the positioning information comprises uplink resource configuration information;
wherein a configuration mode of the uplink resource configuration information comprises one of the following:
the uplink resource configuration information is configured based on configuration information of the positioning signal and/or the measurement time information of the positioning signal;
the uplink resource configuration information is configured based on an uplink resource request; and
the uplink resource configuration information is preconfigured by a protocol or a higher layer.

11. The positioning method according to claim 1 , wherein the determining the positioning signal based on the positioning information comprises:
determining a to-be-measured positioning signal based on the positioning information; or
determining a to-be-sent positioning signal based on the positioning information.

12. The positioning method according to claim 1 , wherein the positioning signal is an aperiodic sounding reference signal SRS with a target priority; and
after the determining the positioning signal based on the positioning information, the method further comprises:
sending the aperiodic sounding reference signal (SRS) to a network device based on the positioning information.

13. The positioning method according to claim 1 , wherein the measurement is performed only on a current bandwidth part.

14. A terminal, comprising a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein when the computer program is executed by the processor, steps of a positioning method are implemented, wherein the method comprises:
obtaining positioning information, wherein the positioning information comprises priority information related to a positioning signal, and measurement time information of the positioning signal; and
determining the positioning signal based on the positioning information;
wherein the determining the positioning signal based on the positioning information comprises:
measuring a positioning reference signal (PRS) based on measurement time information in configuration information of the PRS and configuration information of a target priority of the PRS;
wherein, the priority information related to the positioning signal comprises a priority relation between the positioning signal and another signal or between the positioning signal and data service;
the method further comprises:
dropping low-priority data, in a case that the positioning signal overlaps the low-priority data.

15. The terminal according to claim 14 , wherein the measurement time information is configuration information of at least one measurement time window.

16. The terminal according to claim 15 , wherein the configuration information of the at least one measurement time window further comprises start time information of the at least one measurement time window; and
the start time is determined based on following:
an offset relative to a system frame number or a slot number of a serving cell or base station.

17. A network device, comprising a memory, a processor, and a computer program stored in th
