Abstract

Disclosed in the present application are a positioning measurement method and apparatus, a device and a readable storage medium. The method comprises: a terminal measures a plurality of positioning reference signals in a first positioning measurement window; and the terminal determines location information of the terminal according to the measurement result of the plurality of positioning reference signals.

First claim

The invention claimed is:

1 . A positioning measurement method, comprising:
performing, by a terminal, measurement on a plurality of positioning reference signals within a first positioning measurement window; and determining, by the terminal, location information of the terminal based on measurement results of the plurality of positioning reference signals; wherein the first positioning measurement window is determined based on one or more of the following:
configuration information of the first positioning measurement window;
first request information, wherein the first request information is used to request for the first positioning measurement window; and
wherein the configuration information of the first positioning measurement window comprises: identification information of the first positioning measurement window; time domain information of the first positioning measurement window; and a priority of the first positioning measurement window.

2 . The method according to claim 1 , wherein the first positioning measurement window is determined further based on a plurality of first positioning search windows;
wherein the plurality of first positioning search windows have at least one of the following characteristics: each of a plurality of TRPs is configured with a same or different first positioning search windows; the number of first positioning search windows of the plurality of TRPs is the number of TRP groups; and the plurality of first positioning search windows comprise one or more maximum search ranges, wherein the maximum search range limits a range of the first positioning search window.

3 . The method according to claim 1 , wherein the configuration information of the first positioning measurement window further comprises one or more of the following:
identification information of the first positioning measurement window; time domain information of the first positioning measurement window; frequency domain information of the first positioning measurement window; a priority of the first positioning measurement window; positioning reference signal configuration information of one or more TRPs relative to the first positioning measurement window; or first positioning search window information of a plurality of TRPs relative to the first positioning measurement window.

4 . The method according to claim 3 , wherein the frequency domain information of the first positioning measurement window comprises one or more of the following:
a frequency domain starting point of the first positioning measurement window; bandwidth information of the first positioning measurement window; a frequency domain granularity of the first positioning measurement window; a subcarrier spacing of the first positioning measurement window; and a frequency domain offset of the first positioning measurement window.

5 . The method according to claim 4 , wherein a frequency domain starting point of the first positioning measurement window is a starting point of an active BWP.

6 . The method according to claim 3 , wherein in a case that the first positioning measurement window has been configured for the terminal, the terminal needs to perform radio resource management (RRM) measurement, and the RRM measurement needs to be performed in a measurement gap, requesting, by the terminal, for configuration of a second measurement gap.

7 . The method according to claim 1 , wherein the method further comprises: receiving the configuration information of the first positioning measurement window.

8 . The method according to claim 1 , wherein the time domain information of the first positioning measurement window comprises one or more of the following:
a start time of the first positioning measurement window; a window length of the first positioning measurement window; a time domain type of the first positioning measurement window; a repetition parameter of the first positioning measurement window; and a time interval between repeated first positioning measurement windows.

9 . The method according to claim 1 , wherein the first request information comprises:
measurement configuration information of one or more positioning reference signals.

10 . The method according to claim 1 , wherein the method further comprises:
transmitting the first request information in a first transmission manner; wherein the first transmission manner comprises one or more of the following: uplink control information; radio resource control signaling; media access control control element; long-term evolution positioning protocol; and new radio positioning protocol A.

11 . The method according to claim 1 , wherein the first positioning measurement window is determined further based on a first measurement gap;
wherein information about the first measurement gap comprises one or more of the following: identification information of the first measurement gap; configuration information of the first measurement gap; and a priority of the first measurement gap.

12 . The method according to claim 1 , wherein the performing, by a terminal, measurement on a plurality of positioning reference signals within a first positioning measurement window comprises:
in response to a first event, performing, by the terminal, measurement on the plurality of positioning reference signals within the first positioning measurement window, wherein the first event comprises one or more of the following: a positioning response latency is less than a first threshold; a positioning service latency indicator is less than a second threshold; the positioning service is a specific positioning service; a first measurement gap is unable to satisfy a requirement; request for the first measurement gap fails; one or more positioning reference signals are sent in an active bandwidth part BWP; one or more positioning reference signals are sent in a specific frequency domain range; and configuration of the first measurement gap fails.

13 . The method according to claim 1 , wherein the method further comprises:
in response to a second event, receiving, by the terminal, the configuration information of the first positioning measurement window or sending, by the terminal, first request information, wherein the second event comprises one or more of the following: a positioning response latency is less than a first threshold; a positioning service latency indicator is less than a second threshold; the positioning service is a specific positioning service; a first measurement gap is unable to satisfy a requirement; request for the first measurement gap fails; one or more positioning reference signals are sent in an active bandwidth part BWP; one or more positioning reference signals are sent in a specific frequency domain range; and configuration of the first measurement gap fails.

14 . The method according to claim 1 , wherein the first positioning measurement window and a first measurement gap used for positioning reference signal measurement are not simultaneously configured for the terminal.

15 . The method according to claim 1 , wherein if the first positioning measurement window has been configured for the terminal, the terminal does not request for a first measurement gap used for positioning reference signal measurement or the first measurement gap is not configured.

16 . The method according to claim 1 , wherein if a second measurement gap and the first positioning measurement window have been configured for the terminal,
the first positioning measurement window i
