In order to make those skilled in the art better understand the technical solutions of the embodiments of the present invention, the following description is made.
An Observed Time Difference of Arrival (OTDOA) is a positioning method defined in 3GPP protocol specifications. The basic principle of OTDOA is: a User terminal (UE) measures Downlink Positioning Reference Signals (PRS) transmitted from multiple Transmission Points (TPs), and possibly also Downlink Reference Signals (DL-RS), to obtain Reference Signal Time Difference (RSTD) measurements of arrival at the UE, and reports them to a positioning server in the network to estimate the location of the UE. The Location server is called a Local Management Function (LMF) in a next Generation Radio Access Network (NG-RAN).
In the OTDOA Positioning process, the LMF needs to obtain OTDOA auxiliary information associated with a cell from a Base Station (BS) through a Positioning Protocol specified by 3GPP, such as NRPPa (NR Positioning Protocol a), for example: physical cell ID, antenna location and PRS configuration of the cell, etc. Then, the UE obtains OTDOA assistance information for supporting RSTD measurement from the LMF through a Positioning Protocol specified by 3GPP, for example, LPP (LTE Positioning Protocol).
The basic positioning flow of OTDOA including "positioning information transmission process triggered by UE" and "positioning information transmission process triggered by LMF" includes the following 11 steps:
(1) after the UE establishes a connection with the BS, the UE is in a radio resource control CONNECTED (RRC _ CONNECTED) state.
(2) The positioning server sends a 'request positioning capability' message to the UE, and the request UE informs the server of the positioning functions which can be supported by the UE.
(3) The UE sends a "provide location capability" message in response to the location server. And reporting the positioning capability supported by the NG-RAN OTDOA by the UE, namely the terminal, through the positioning capability providing message.
(4) When downlink positioning assistance data is needed, the UE sends a "request positioning assistance data" message to the positioning server. The message includes a request for the positioning server to provide OTDOA assistance data.
(5) The positioning server sends an "OTDOA INFORMATION REQUEST (NRPPa OTDOA INFORMATION REQUEST)" message to the BS requesting the BS to provide downlink positioning assistance data, such as PRS configuration data.
(6) The BS sends an "OTDOA information response (NRPPa OTDOA information response)" message to the location server. Providing the requested downlink positioning assistance data, including the PRS configuration data, to a positioning server.
(7) The positioning server provides positioning assistance data requested by the UE in a "provide positioning assistance data" message, which carries PRS configuration data.
(8) The location server sends a "request location information" message to the UE. The message requests the UE to measure the downlink PRS of the BS and to reply with the measured positioning measurement values.
(9) The UE measures downlink signals with positioning assistance data (e.g., PRS configuration data) to obtain positioning measurement values (e.g., RSTD).
(10) The UE sends a "provide positioning information" message to the positioning server, which includes positioning measurement values (e.g., RSTD) obtained by measuring the downlink PRS.
(11) The positioning server calculates the position of the UE by using the positioning measurement value obtained by the UE.
It should be noted that, in time, (5) and (6) have no tandem relationship with (1) to (4). Namely: (5) and (6) may occur before, after, or simultaneously with (1) through (4).
The "LMF triggered location information transmission procedure" includes all 11 steps; the "UE triggered positioning information transmission procedure" includes 10 steps in addition to (8).
The transmission process of the positioning information in the LTE system is described above, but there is no relevant scheme for the NR system to report the positioning measurement quantity.
Based on this, as shown in fig. 2, an embodiment of the present invention provides a method for reporting a positioning measurement quantity, which is applied to a terminal, and includes:
step 201: and acquiring measurement configuration information, wherein the measurement configuration information comprises S Positioning Reference Signal (PRS) resources and the reported number K of target measurement quantities.

Further, the value of M is equal to the number of the first target measurement quantities in the N target measurement quantities;

The method for reporting positioning measurement quantity of the present invention is described with reference to the following embodiments.
The first embodiment is as follows:
the network side configures the terminal to measure S-30 PRS resources corresponding to different or same cells, and reports K-20 RSTD measurement values of different cells.
(1) The terminal receives the configuration of the network, measures each PRS resource respectively, and obtains the measurement results of the time of arrival (TOA) of 25 different cells (N is less than or equal to S).
(2) And the terminal calculates N-1-24 RSTD measurement values according to the N-25 TOA results, wherein each RSTD measurement value is the difference between the TOA value of the resource and the TOA value of the reference resource.
(3) And the terminal determines an RSTD measurement quality indicator corresponding to each of the N-1-24 RSTD measurement values and used for indicating the quality of the RSTD measurement. For example, the predefined RSTD measurement quality indication in the system is divided into a first level and a second level, wherein the first level has a better quality than the second level.

The terminal reports only the first level of M-6 RSTDs indicating the measurement quality to the network side, and simultaneously reports M-6 to the network. Since the number M of RSTDs reported by the terminal side is smaller than the number of RSTDs configured by the network side, in order to enable the network side to decode correctly, M ═ 6 needs to be reported to the network as a first part, and RSTDs need to be reported to the network as a second part.

In this embodiment, the terminal reports the measurement quantities smaller than the network side configuration quantity, that is, the target measurement quantity with the measurement quality indication of the first level is reported to the terminal, so as to reduce the reporting overhead of the terminal.
Example two:
The network side configures the terminal to measure S-30 PRS resources corresponding to different or same cells, and reports K-20 RSTD measurement values of different cells.
(1) The terminal receives the configuration of the network, measures each PRS resource respectively, and obtains the measurement results of the time of arrival (TOA) of 25 different cells (N is less than or equal to S).
(2) And the terminal calculates N-1-24 RSTD measurement values according to the N-25 TOA results, wherein each RSTD measurement value is the difference between the TOA value of the resource and the TOA value of the reference resource.
(3) And the terminal determines an RSTD measurement quality indicator corresponding to each of the N-1-24 RSTD measurement values and used for indicating the quality of the RSTD measurement. For example, the predefined RSTD measurement quality indication in the system is divided into a first level and a second level, wherein the first level has a better quality than the second level.
