Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes the positioning method, the positioning apparatus and the electronic device according to the present invention with reference to fig. 1 to 5.
The positioning method provided by the embodiment of the invention can be applied to a base station in a networking mode of a 5G NR (New Radio) system.
The Base station includes a BBU (Building Base band Unit), an RRU (Remote Radio Unit), and an LMF (Location Management Function server).
The positioning method of the embodiment of the invention mainly comprises a step 110, a step 120, a step 130 and a step 140.
Step 110, the BBU controls the M RRUs to respectively send downlink positioning reference signals DL PRS with different time parameters to the user equipment UE at different times.
It should be noted that, in the NR system, when a plurality of RRUs are connected to one BBU, different DL PRS (Downlink Position Reference Signal) parameters are configured for the plurality of RRUs.
In the related art, a plurality of RRUs are all used as radio frequency extensions of one BBU, and a UE (User Equipment) can only use the plurality of RRUs as one cell, and cannot distinguish which RRUs transmit the same DL PRS sent by the plurality of RRUs.
In this embodiment, different configured DL PRS parameters may have the same subcarrier spacing, CP type, center frequency point, PointA, PRS bandwidth, and starting PRB location. However, the BBU may configure that PRS signals corresponding to M different DL PRS positioning frequency layer parameters do not overlap in the time domain.
Time domains of PRS signals corresponding to the M different DL PRS positioning frequency layer parameters may be configured. I.e. the periods may be the same but offset differently or the periods may be different but offset to ensure different times of transmission.
In other words, each RRU is configured with DL PRS parameters having different time parameters, as shown in fig. 2 and fig. 3, each RRU corresponds to each configured DL PRS positioning frequency layer parameter one to one, and the BBU controls each RRU to sequentially transmit different DL PRS to the UE from 1-M according to a time sequence, where M is a positive integer less than or equal to M.
In this case, the UE may receive, at a corresponding time point, the DL PRS transmitted by each RRU according to the advanced configuration of the base station, and detect and determine measurement information of the RRU corresponding to each DL PRS.
And step 120, each RRU receives the measurement information of all RRUs reported by the UE and reports the measurement information of all RRUs to the BBU.
It can be understood that the measurement information of all RRUs is obtained by the UE receiving and measuring all DL PRSs.
And the UE detects and reports the measurement information of the RRUs corresponding to the DL PRS to all the RRUs after receiving the DL PRS at different time points, and the RRUs report the currently received measurement information of the RRUs to the BBU.
It can be understood that the BBU may mark the identifiers of the M connected RRUs, and the position information and the transmitting antenna angle information of each RRU as a TRP (Transmit-Receive Point), so as to determine the corresponding relationship between each RRU and the measurement information.
And step 130, the BBU determines the measurement information corresponding to each RRU, and reports the measurement information corresponding to each RRU to the LMF.
It can be understood that the BBU may determine the measurement information corresponding to each RRU according to a plurality of measurement information reported by the RRUs.
The measurement information of the RRU includes a downlink reference signal time difference of arrival DL RSTD and a downlink reference signal received power DL RSRP.
In this embodiment, the BBU may determine the measurement information corresponding to each RRU according to the reporting time of the measurement information of all the RRUs.
It should be noted that the BBU controls the M RRUs to respectively send DL PRS to the UE at different times, and the BBU can determine a time sequence corresponding to each RRU, and further determine measurement information of each RRU according to the reporting time of the measurement information of all the RRUs.
In this embodiment, according to the DL PRS parameters configured for the RRUs in advance, the measurement information of each RRU determined by the UE can be determined.
After determining the measurement information of each RRU, the BBU may send the measurement information corresponding to each RRU to the LMF.
Step 140, the LMF determines the location information of the UE according to the measurement information corresponding to each RRU and the location information of each RRU;
it is understood that the LMF may use DL TDOA (Downlink Time Difference of Arrival) or DL AOD (Downlink Angle of Departure) to perform UE positioning.
In some embodiments, DL TDOA may be utilized for location of the UE.
In this embodiment, the LMF calculates the distance difference from the UE to the RRU according to the DL RSTD in the measurement information corresponding to each RRU and the reporting time of the measurement information of each RRU, that is, by measuring the time difference between the arrival of the signal at the mobile phone and the two neighboring base stations.
In this case, the UE is located on a hyperbolic curve with multiple RRUs as the focal points and the distance differences as the fixed differences. When M is 3, two or more hyperbolas can be formed by three RRUs, and the intersection point is the two-dimensional position coordinate of the UE.
Namely, the position information of each RRU is used to determine the curve position corresponding to each RRU, and further determine the intersection point position of the curve, i.e. the two-dimensional position coordinate of the UE.
In other words, the LMF may determine the location information of the coincidence location of the curve locations corresponding to all the RRUs as the location information of the UE.
In this embodiment, the position of the UE can be determined by the reporting time difference of different RRUs, thereby achieving positioning of the UE.
In other embodiments, the DL AOD may be utilized for positioning of the UE.
In this embodiment, both the UE and the RRUs adopt multi-antenna configuration, and the LMF determines the transmitting antenna angle of each RRU according to the measurement information downlink reference signal received power DL RSRP corresponding to each RRU.
The LMF may determine the location information of the UE according to the transmit antenna angles of all RRUs.
In this embodiment, the sending antenna angle can be determined by DL RSRP of different RRUs, and then the position of the UE is determined, and further positioning of the UE is achieved.
It should be noted that, according to the specification of 3GPP R16 TS38.331, the UE can configure 4 DL PRS positioning frequency layer parameters at most, and the UE can report 4 DL RSTDs/RSRP at most.
When the UE is located through DL TDOA, at least three RRUs are needed to achieve location, so M may be 3 or 4.
According to the positioning method provided by the embodiment of the invention, the BBU controls the plurality of RRUs to respectively send the DL PRSs to the UE at different moments, and the corresponding relation between the measurement information of the UE and each RRU can be determined according to different reported time sequences, so that the LMF can determine the position information of the UE.

According to the positioning device provided by the embodiment of the invention, the BBU controls the plurality of RRUs to respectively send the DL PRSs to the UE at different moments, and the corresponding relation between the measurement information of the UE and each RRU can be determined according to different reported time sequences, so that the LMF can determine the position information of the UE.
