Abstract

The present disclosure relates to information processing methods, communications devices, systems, and storage medium. One example method includes generating, by a network device, first configuration information of an uplink reference signal, where the first configuration information includes a first mapping relationship between an uplink reference signal resource and first information, the first information is number information or index information about a downlink reference signal of a location measurement unit (LMU), and the LMU is different from the network device, and sending, by the network device, the first configuration information to a terminal.

First claim

What is claimed is:

1. An information processing method, comprising:
receiving, positioning request information, wherein the positioning request information carries identification information of a location measurement unit;
generating, first configuration information of an uplink reference signal, wherein the first configuration information comprises a first mapping relationship between an uplink reference signal resource and first information, wherein the first information is number information or index information about a downlink reference signal of the location measurement unit, and wherein the location measurement unit is different from network device;
sending, the first configuration information to a terminal device; and
sending, second configuration information to a positioning entity, wherein the second configuration information comprises a second mapping relationship between the uplink reference signal resource and the location measurement unit.

2. The method according to claim 1 , wherein the downlink reference signal is measured by the terminal device.

3. The method according to claim 1 , wherein the
positioning request information is received from the positioning entity and is for the terminal device.

4. The method according to claim 1 , wherein the first configuration information further comprises a second mapping relationship between the uplink reference signal resource and the location measurement unit.

5. The method according to claim 1 , wherein the identification information of the location measurement unit comprises at least one of the following:
a physical cell identifier (PCI);
a cell global identifier;
a frequency;
an indication indicating whether a supplementary uplink (SUL) band is supported; and
a sequence number of the downlink reference signal.

6. The method according to claim 1 , wherein the uplink reference signal is a sounding reference signal (SRS), and wherein the uplink reference signal resource is an SRS resource.

7. The method according to claim 1 , wherein the first mapping relationship comprises a second mapping relationship between the uplink reference signal resource and the location measurement unit.

8. An information processing method, comprising:
receiving first configuration information from a network device, wherein the first configuration information comprises at least a first mapping relationship between an uplink reference signal resource and first information, wherein the first information is number information or index information about a downlink reference signal of a location measurement unit, and wherein the location measurement unit is different from the network device; and
sending, based on the first mapping relationship in the first configuration information, an uplink reference signal on the uplink reference signal resource included in the first mapping relationship and in a beam direction indicated by the first information corresponding to the uplink reference signal resource.

9. The method according to claim 8 , wherein the first configuration information further comprises a second mapping relationship between the uplink reference signal resource and the location measurement unit.

10. The method according to claim 8 , wherein the downlink reference signal is measured by a terminal device.

11. The method according to claim 8 , wherein identification information of the location measurement unit comprises at least one of the following:
a physical cell identifier (PCI);
a cell global identifier;
a frequency;
an indication indicating whether a supplementary uplink (SUL) band is supported; and
a sequence number of the downlink reference signal.

12. The method according to claim 8 , wherein the uplink reference signal is a sounding reference signal (SRS), and wherein the uplink reference signal resource is an SRS resource.

13. The method according to claim 8 , wherein the first mapping relationship comprises a second mapping relationship between the uplink reference signal resource and the location measurement unit.

14. An apparatus, comprising:
at least one processor; and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
receiving, positioning request information, wherein the positioning request information carries identification information of a location measurement unit;
generating first configuration information of an uplink reference signal, wherein the first configuration information comprises a first mapping relationship between an uplink reference signal resource and first information, wherein the first information is number information or index information about a downlink reference signal of the location measurement unit, and wherein the location measurement unit is different from a network device;
sending the first configuration information to a terminal device; and
sending second configuration information to a positioning entity, wherein the second configuration information comprises a second mapping relationship between the uplink reference signal resource and the location measurement unit.

15. An apparatus, comprising:
at least one processor; and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
receiving first configuration information from a network device, wherein the first configuration information comprises at least a first mapping relationship between an uplink reference signal resource and first information, wherein the first information is number information or index information about a downlink reference signal of a location measurement unit, and wherein the location measurement unit is different from the network device; and
sending, based on the first mapping relationship in the first configuration information, an uplink reference signal on the uplink reference signal resource included in the first mapping relationship and in a beam direction indicated by the first information corresponding to the uplink reference signal resource.

16. The apparatus according to claim 15 , wherein the first configuration information further comprises a second mapping relationship between the uplink reference signal resource and the location measurement unit.
