Abstract

A positioning method includes: transmitting or receiving, by a terminal, first information; and performing, by the terminal, a positioning operation based on the first information, where the first information includes at least one of the following: configuration information of first positioning reference signals, where the configuration information includes at least one of the following: activation state configuration information, reporting state configuration information, first time domain offset information, second time domain offset information, or configuration information of beam switching or QCL switching; or activation information, where the activation information is used to activate transmission of a first target positioning reference signal, and/or the activation information is used to activate reporting of a second target positioning reference signal, where the first target positioning reference signal includes one or more of the first positioning reference signals, and the second target positioning reference signal includes one or more of the first positioning reference signals.

First claim

What is claimed is:

1 . A positioning method, wherein the method comprises:
receiving, by a terminal, first information; and performing, by the terminal, a positioning operation based on the first information; wherein the first information comprises:
configuration information of first positioning reference signals, wherein the configuration information of the first positioning reference signals comprises at least one of the following: activation state configuration information, reporting state configuration information, first time domain offset information, second time domain offset information, or configuration information of beam switching or quasi-co-location (QCL) switching; the configuration information of the first positioning reference signals further comprises: configuration information of a first configuration window, and the configuration information of the first configuration window comprises at least one of the following:
the first configuration window of a positioning reference signal indicated by first identification (ID) information;
start time information of the first configuration window;
window length information of the first configuration window; or
period information of the first configuration window;

or
activation information, for activating measurement or reporting of a second target positioning reference signal, wherein the second target positioning reference signal comprises one or more of the first positioning reference signals;
wherein the activation information comprises at least one of the following:
a second bit string used to indicate activating a target measurement gap (MG); or
a sixth bit string used to activate or switch to a first target configuration window, wherein the first target configuration window is associated with the first configuration window; and

wherein the first configuration window includes at least one of the following: a search window, a measurement window, an MG window, or a reporting window.

2 . The method according to claim 1 ,
wherein the activation state configuration information comprises at least one of the following: at least one piece of first activation state information, wherein one piece of first activation state information is associated with one or more first positioning reference signal groups, wherein a first positioning reference signal group comprises at least one positioning reference signal in the first positioning reference signals; at least one piece of first activation state information, wherein one piece of first activation state information is associated with first positioning reference signals of one or more first unit resources, wherein a first unit resource comprises at least the following: a positioning reference signal resource, a positioning reference signal resource set, a positioning reference signal resource corresponding to one transmission reception point (TRP), and a positioning reference signal resource corresponding to one frequency layer; or at least one first activation state list, wherein the first activation state list is used to record an association relationship between the first activation state information and the first positioning reference signal group; and/or the reporting state configuration information comprises at least one of the following: at least one piece of second activation state information, wherein one piece of second activation state information is associated with one or more second positioning reference signal groups, wherein a second positioning reference signal group comprises at least one positioning reference signal in the first positioning reference signals; at least one piece of second activation state information, wherein one piece of second activation state information is associated with first positioning reference signals corresponding to one or more of the first unit resources; or at least one second activation state list, wherein the second activation state list is used to record an association relationship between the second activation state information and the second positioning reference signal group.

3 . The method according to claim 2 , wherein a first positioning reference signal in the first positioning reference signal group and/or a first positioning reference signal in the second positioning reference signal group comprise at least one of the following: an aperiodic positioning reference signal, a semi-static positioning reference signal, a periodic positioning reference signal, or an on-demand positioning reference signal;
or a positioning reference signal in the first positioning reference signal group and/or a positioning reference signal in the second positioning reference signal group satisfy one of the following: having a same signal time domain type; having a same bandwidth part (BWP) ID; having a same frequency layer; having a same time domain parameter, wherein the time domain parameter comprises at least one of the following: period, slot offset, muting parameter, or number of repetitions; belonging to a same positioning reference signal resource set; belonging to a same active group setting; having a same group ID; having a same resource parameter, wherein the resource parameter comprises at least one of the following: beam, beam group, resource set ID, resource ID, or quasi-co-location (QCL) information; belonging to one or more first unit resources, wherein the first unit resource comprises one of the following: the positioning reference signal resource, the positioning reference signal resource set, the positioning reference signal resource corresponding to one TRP, and the positioning reference signal resource corresponding to one frequency layer; having a same reporting type; having a same reporting configuration; having a same measurement type; having a same measurement configuration; having a same reporting group; and having a same measurement group; or one piece of the first activation state information is associated with one or more first positioning reference signal groups, wherein the first positioning reference signal group is associated with one or more first settings, and a first setting comprises: a positioning reference signal reporting setting and/or a positioning reference signal resource setting; and/or one piece of the second activation state information is associated with one or more second positioning reference signal groups, wherein the second positioning reference signal group is associated with one or more second settings, and a second setting is associated with one or a group of first settings.

4 . The method according to claim 2 , wherein the first activation state list and/or the second activation state list comprises at least one of the following:
a semi-static activation state list, wherein a positioning reference signal in the semi-static activation state list is a semi-static positioning reference signal; an aperiodic activation state list, wherein a positioning reference signal in the aperiodic activation state list is an aperiodic positioning reference signal; or an on-demand activation state list, wherein a positioning reference signal in the on-demand activation state list is an on-demand positioning reference signal; or the positioning reference signal resource setting comprises one or a group of first unit resources, wherein the first unit resource comprises one of the following: a positioning reference signal resource, a positioning reference signal resource set, a positioning reference signal resource corresponding to one TRP, and a positioning reference signal resource corresponding to one frequency layer; or positioning reference signals contained in one positioning reference signal resource set satisfy one of the following: having a same signal time domain type; havin
