[0129] For UE-assisted positioning, including additional measurements, the UE can report a total of 8 RSRPs. For UE-based positioning, it depends on the UE implementation.
[0130] 1.4 Method for AoD accuracy optimization based on beam pattern and RSRP
[0131] like Figure 3 As shown, the thin solid line and the thick solid line are the two-dimensional beam patterns of beam1 and beam2, respectively. The horizontal axis corresponds to the beam angle, and the vertical axis corresponds to the normalized beam response.
[0132] The UE receives m PRS and obtains m RSRPs based on the measurements of the m PRS. If the UE selects n RSRPs from the m RSRPs to report, then an n-dimensional vector [RSP1 RSRP2 ……RSRPn] can be formed based on these n RSRPs.
[0133] On the LMF side, given the beam pattern of the transmit beam corresponding to each PRS, if the angle granularity is 1, then the beam response of the transmit beam of the PRS corresponding to these n RSRPs can be obtained at 360 angles. This beam response vector is [BeamResponse1 BeamResponse1 …… BeamResponsen]. The Euclidean distance between these two vectors (the RSRP vector and the beam response vector reported by the UE) is calculated, and the angle corresponding to the vector with the smallest Euclidean distance is the AOD angle to be measured.
[0134] For details, please refer to [link / reference]. Figure 4 When the selected n RSRPs include the strongest PRS and adjacent PRSs, the optimization accuracy is high. For example, when the actual AOD corresponds to the beam highlighted in black in the figure, the measured RSRP of the PRS corresponding to the highlighted beam is the strongest. In this case, if the measured RSRPs of the PRS corresponding to the adjacent beams, such as the beams on both sides of the highlighted beam, are also reported, the AOD optimization accuracy is high.
[0135] However, when the UE reports the RSRP of the PRS, it cannot definitively determine which PRS transmission beams are adjacent or superior. If the reported PRS transmission beam angles differ significantly, or if adjacent beams are not included, the optimization effect is significantly reduced when the LMF uses RSRP for AOD optimization. Furthermore, the number of RSRPs reported by each UE at each Transmit and Receive Point (TRP) is uncertain, with a maximum of eight. Even when the reported RSRPs include those of adjacent beams, reporting only a smaller number of RSRPs can still achieve good AOD optimization performance.
[0136] Please refer to Figure 5 This application provides a positioning method, including:
[0137] Step 51: The terminal determines the target positioning reference signal;
[0138] In this embodiment of the application, the number of target positioning reference signals determined by the terminal can be one or more.
[0139] Step 52: The terminal determines the first measurement information of the target positioning reference signal, and / or reports the first measurement information of the target positioning reference signal, wherein the first measurement information is used to determine the terminal location information;
[0140] The target positioning reference signal is determined according to at least one of the following methods:
[0141] Predefined rules;
[0142] The network side sends first auxiliary information, which is used to configure information related to the positioning reference signal beam.
[0143] The network side sends a first request message, which is used to indicate the positioning reference signal or configuration update that the network side expects to report.
[0144] In this embodiment of the application, the terminal is instructed to measure and / or report first measurement information of which target positioning reference signals is more conducive to improving positioning accuracy by means of at least one of predefined rules, network-side configuration and network-side request, so that the UE can determine better positioning reference signals, measure and / or report the first measurement results of these positioning reference signals, thereby improving the accuracy of AOD.
[0145] (a) The content of the first measurement information will be explained below.
[0146] In this embodiment of the application, optionally, the first measurement information includes at least one of the following:
[0147] 1) RSRP information;
[0148] 2) Phase information;
[0149] 3) First diameter RSRP information;
[0150] The RSRP in the current protocol is the RSRP of PRS (average or weighted RSRP of multipaths), the first path RSRP information is the RSRP of the first path measured by the UE, and the reference path RSRP information is the RSRP of a certain reference path measured by the UE. They are all obtained based on path measurements.
[0151] 4) First-diameter phase information;

[0162] 3) The first path is the path with the smallest delay among the first detected paths of several PRS resources or SRS resources. The first detected path under each PRS resource or SRS resource, that is, the path with the smallest distance between the time of receiving the path and the start time of subframe i, is the first path of that PRS resource or SRS resource. Subframe i is the subframe that receives the PRS resource or SRS resource. The path with the smallest delay among the first detected paths is the first path.
[0163] 4) The first path is the path with the smallest delay among the first detected paths of several PRS resources or SRS resources. The first detected path under each PRS resource or SRS resource, that is, the path with the smallest distance between the time of receiving the path and the start time of symbol i, is the first path of that PRS resource or SRS resource. Here, symbol i is the subframe in which the PRS resource or SRS resource is received. The path with the smallest delay among the first detected paths is the first path.

[0170] 2) Linear average of the phase values of the resource elements carrying the DL PRS reference signal of the RSRP measurement configuration on the first diameter within the considered measurement frequency bandwidth.
[0171] 3) The phase value of the DL PRS reference signal carrying the RSRP measurement configuration on the first path of each resource element within the considered measurement frequency bandwidth.
[0172] The definition of the initial diameter angle includes one of the following:
[0173] 1) The arrival / departure angle of the first diameter relative to a reference direction, which may be in the global coordinate system (GCS) or in the local coordinate system (LCS);
[0174] The definition of initial diameter RSTD includes one of the following:
[0175] 1) The relative time difference between downlink subframes between transmission point (TP) j and reference TP i is defined as TSubframeRxj - TSubframeRxi, where downlink subframe j and downlink subframe i are the subframes of the first path of the received positioning reference signal, respectively.
[0176] 2) The relative time difference of downlink symbols between transmission point (TP) j and reference TP i is defined as TSubframeRxj - TSubframeRxi, where downlink symbol j and downlink symbol i are the symbols of the first path of the received positioning reference signal, respectively.
[0177] The definition of TOA (Total Angle of Appearance) includes one of the following:
[0178] 1) The relative time difference between the start of subframe i received by receiver point (RP) j and the reference time, where subframe i is the first subframe in which the positioning reference signal is received;
[0179] 2) The relative time difference between the start of symbol i received by receiver point (RP) j and the reference time, where symbol i is the symbol of the first path of the received positioning reference signal.
[0180] In this embodiment of the application, optionally, the first precoding matrix information is used to determine angle information, including at least one of the following:
[0181] The index of the largest precoding matrix in RSRP;
[0182] The index of the precoding matrix with the largest first path in RSRP;
[0183] Index of the precoding matrix with the maximum bandwidth in RSRP;
[0184] The index of the precoding matrix with the largest bandwidth in the first path RSRP;
[0185] The index of the largest narrowband precoding matrix in RSRP;
[0186] The index of the narrowband precoding matrix with the largest first-path RSRP;
[0187] Precoding matrix index;
[0188] RSRP corresponding to the precoded matrix index;
[0189] The first path RSRP corresponding to the precoding matrix index;
[0190] Adjacent precoding matrix index;
[0191] RSRP corresponding to adjacent precoding matrix indices;
[0192] The first path RSRP corresponding to adjacent precoding matrix indices;
[0193] Wideband precoding matrix index;
[0194] RSRP corresponding to the wideband precoding matrix index;
[0195] The first path RSRP corresponding to the wideband precoding matrix index;
[0196] Adjacent wideband precoding matrix index;

[0204] The first path RSRP corresponding to the adjacent narrowband precoding matrix index.
[0205] The precoding matrix and angle information are in one-to-one correspondence. It can be understood that one precoding matrix corresponds to one angle. By searching the precoding matrix, each precoding matrix and channel can calculate an RSRP (energy), or each precoding matrix and first path channel can calculate a first path RSRP (first path energy). The angle corresponding to the precoding matrix with the largest energy is the estimated angle of arrival. The energy values and index values of adjacent precoding matrices help to further improve positioning accuracy.
[0206] Optionally, the adjacent precoding matrices are indicated by at least one of the following methods:
[0207] 1) Indicated by indexing through the Precoding Matrix Indicator (PMI);
[0208] For example, precoding matrices with adjacent indices are called adjacent precoding matrices, such as precoding matrices with indices 1, 2, and 3.
[0209] 2) By the angle indication corresponding to the pre-encoded matrix.
[0210] For example, if the angles corresponding to the precoding matrices are adjacent, and there are a total of 360 precoding matrices with corresponding angles of 0, 1, 2, ..., 359, then the precoding matrices with angles of 1, 2, and 3 degrees are adjacent precoding matrices.
[0211] The first measurement information in the above embodiments is typically used in the AOD positioning method.

[0619] 1) A list of horizontal positioning reference signal identification information, such as {PRS resource ID1, PRS resource ID2, ..., PRS resource IDn}, indicating the ID of the PRS that is adjacent to or better than dl-PRS-Resource ID-r16 in the horizontal direction.
[0620] 2) A list of vertical positioning reference signal identification information, such as {PRS resource ID1, PRS resource ID2, ..., PRS resource IDn}, indicating the ID of the PRS that is vertically adjacent to or better than dl-PRS-Resource ID-r16.
[0621] 3) A list of three-dimensional orientation positioning reference signal identification information, such as {PRS resource ID1, PRS resource ID2, ..., PRS resource IDn}, indicating the IDs of PRS that are adjacent to or better than dl-PRS-Resource ID-r16 in the three-dimensional direction.
[0622] Sending beam index information includes at least one of the following:
[0623] 1) Transmit beam indexes in the horizontal direction. If there are 8 beam angles in the horizontal direction, the beams are indexed in a certain order. For example, the beam index of the first beam in the horizontal direction is 1, the beam index of the second beam is 2, and so on, until the beam index of the eighth beam is 8. If the beam index of the first positioning reference signal measured by the UE is 3, then the PRS corresponding to the two horizontal beam indices (1 and 2) adjacent to 3 is the adjacent PRS or a better PRS in the horizontal direction.
[0624] 2) Vertical beam index transmission. If there are 8 beam angles in the vertical direction, the beams are indexed in a certain order. For example, the beam index of the first beam in the vertical direction is 1, the beam index of the second beam is 2, and so on, until the beam index of the eighth beam is 8. If the beam index of the first positioning reference signal measured by the UE is 3, then the PRS corresponding to the two vertical beam indices (1 and 2) adjacent to 3 are the adjacent PRS or a better PRS in the vertical direction.
[0625] 3) Three-dimensional beam indexing. Method 1 uses a horizontal-vertical beam index group. If there are 8 beam angles in the horizontal direction and 8 beam angles in the vertical direction, there are a total of 64 three-dimensional beam angles. The beams are indexed in a certain order. For example, the beam index for [the first beam angle in the horizontal direction and the beam angle for the first beam in the vertical direction] is [1,1], the beam index for [the first beam angle in the horizontal direction and the beam angle for the second beam in the vertical direction] is [1,2], ..., the beam index for [the first beam angle in the horizontal direction and the beam angle for the eighth beam in the vertical direction] is [1,8], ..., the beam index for [the fourth beam angle in the horizontal direction and the beam angle for the fourth beam in the vertical direction] is [4,4], ..., the beam index for [the eighth beam angle in the horizontal direction and the beam angle for the eighth beam in the vertical direction] is [8,8]. If the three-dimensional beam index of the first positioning reference signal measured by the UE is [3,4], then the PRS corresponding to the four beam indices adjacent to [3,4] ([2,4], [4,4], [3,2], [3,5]) are adjacent PRS or better PRS in the three-dimensional direction. Method two involves transmitting beam indices in the three-dimensional direction. For example, if the 64 beams are numbered in a certain order, such as starting from the smallest angle, corresponding to 64 three-dimensional direction transmission beam indices, if the beam index of the first positioning reference signal measured by the UE is 12, then the PRS corresponding to the two three-dimensional beam indices adjacent to 12 (11 and 13) are adjacent PRS or better PRS in the three-dimensional direction.
