本申请涉及通信领域,尤其涉及一种5G场景下的定位方法、定位平台及用户终端。This application relates to the field of communications, and in particular to a positioning method, positioning platform, and user terminal in a 5G scenario.
随着无线通信的快速发展,智能手机、平板电脑等智能无线用户终端(user equipment,UE)已经成为人们生活、工作中不可或缺的工具。上述UE的大规模普及催生了各种基于无线定位的位置服务。如:商场室内导航、精准位置广告推送、老人和小孩实时位置监控、大数据分析数字足迹及与网络优化相关的无线定位服务。目前大部分室内、室外定位方法是基于无线接入点,如无线2G、3G、4G、5G、WiFi、WLAN等接入点,来实现定位。With the rapid development of wireless communication, smart wireless user equipment (UE) such as smart phones and tablet computers have become indispensable tools in people's lives and work. The large-scale popularization of the aforementioned UE has given birth to various location services based on wireless positioning. Such as: shopping mall indoor navigation, accurate location advertising push, real-time location monitoring of the elderly and children, big data analysis of digital footprint and wireless location services related to network optimization. At present, most indoor and outdoor positioning methods are based on wireless access points, such as wireless 2G, 3G, 4G, 5G, WiFi, WLAN and other access points to achieve positioning.
其中,一种常用的定位方法是利用无线网络小区位置进行定位,即增强型小区ID(enhanced cell-ID,ECID)定位,基本原理是:根据UE所处服务小区的服务小区ID(即cell-ID)及服务小区方向角的朝向来确定UE的位置。每个蜂窝小区都有一个唯一的小区ID,当UE在某个小区注册后,在系统的数据库中就会将该UE与该小区ID对应起来,只要知道该小区所处的中心位置和小区的覆盖半径、小区方向角的朝向,就知道UE所处的大致范围,如图1所示,基于UE(以手机为例)上报上来的测量报告(measurement report,MR)中服务小区的ID结合工程参数中服务小区的位置和服务小区方向角的朝向,就可确定手机所处的位置范围。但该方法定位的精度差,且严重依赖该服务小区的覆盖范围大小,一般定位精度在数百米,在小区分布较少的地区(如郊区、农村)难以获得理想的定位精度。另外,由于在无线通信环境中,接收信号强度指示(received signal strength indicator,RSSI)可以通过UE的MR快速获取,所以利用RSSI进行指纹匹配就成为无线定位中最经济和常用的另一方法,该方法称为指纹定位(也可称为无线信号特征匹配),具体方式是:事先记录巨量的确定位置点所处的小区ID和接收信号强度(received signal strength,RSS)(也可称为指纹信息),通过用新加入UE所处位置的小区ID、RSSI对比拥有巨量小区ID、RSS的数据库(也可称为指纹库),从而确定该UE的位置。例如图2中的UE(以手机为例)所处的位置点均被小区1、小区2、小区3的无线网络覆盖,这三个小区在该位置点对应的RSS分别为RSS1、RSS2、RSS3,通过对比手机所处的小区ID、RSSI与该位置点指纹库中的小区ID、RSS,从而确定手机所处的位置。指纹定位在网络2G、3G、4G、WiFi中均有应用,但是2G、3G、4G、WiFi中指纹库是由小区ID和小区的RSS组成,指纹相对单一。并且,2G、3G、4G、WiFi指纹库的定位精度受MR中小区个数的影响较为严重,小区数目越少,定位精度越差。Among them, a commonly used positioning method is to use the cell location of the wireless network to perform positioning, that is, enhanced cell ID (enhanced cell-ID, ECID) positioning. The basic principle is: according to the serving cell ID (ie cell- ID) and the orientation of the serving cell direction angle to determine the location of the UE. Each cell has a unique cell ID. When a UE is registered in a certain cell, the UE will be associated with the cell ID in the system database, as long as the center position of the cell and the cell ID are known. The coverage radius and the orientation of the cell direction angle will know the approximate range of the UE, as shown in Figure 1, based on the ID combination project of the serving cell in the measurement report (MR) reported by the UE (taking a mobile phone as an example) The location of the serving cell and the direction of the serving cell in the parameters can determine the location range of the mobile phone. However, the positioning accuracy of this method is poor, and it is heavily dependent on the coverage area of the serving cell. Generally, the positioning accuracy is hundreds of meters, and it is difficult to obtain ideal positioning accuracy in areas with less cell distribution (such as suburbs and rural areas). In addition, because in the wireless communication environment, the received signal strength indicator (RSSI) can be quickly obtained through the MR of the UE, the use of RSSI for fingerprint matching has become another most economical and commonly used method in wireless positioning. The method is called fingerprint positioning (also called wireless signal feature matching), and the specific method is to record in advance the cell ID and received signal strength (received signal strength, RSS) (also called fingerprint). Information), the location of the UE is determined by comparing the database with a huge number of cell IDs and RSS (also called fingerprint database) with the cell ID and RSSI where the UE is located. For example, the location of the UE in Figure 2 (taking a mobile phone as an example) is covered by the wireless networks of
上述定位方法均是基于无线2G、3G、4G、5G、WiFi、WLAN等接入点来实现定位的,并且定位精度受多方因素影响,导致定位精度不高。The above positioning methods are all based on wireless 2G, 3G, 4G, 5G, WiFi, WLAN and other access points to achieve positioning, and the positioning accuracy is affected by many factors, resulting in low positioning accuracy.

The fingerprint library is the combination of the fingerprint information of each location point in the SrvNR and/or NeighNR wireless coverage area of the UE and the known location information of the corresponding location point. Yes, the fingerprints described in the embodiments of the present application refer to radio fingerprints, which are used to identify radio characteristics (such as the strength of a radio signal), etc. The fingerprint information of each location point is different.

In addition, in order to achieve higher positioning accuracy, the fingerprint library may also include at least one of the first SSB-RSRQ and the first SSB-SINR. ②. When only CSI-RS information is used for positioning, the fingerprint library contains at least the following core information: it must include the GPS information of each location point, and it must include a SrvNR serving cell ID and corresponding CSI-RS information (that is, at least Including CSI-RS ID, CSI-RS RSRP). In addition, similarly, in order to make the positioning accuracy higher, the fingerprint library may also include: CSI-RS SINR. ③. When the first SSB information and the CSI-RS information are used for positioning at the same time, the fingerprint database can contain the information described in ① and ② at the same time. The details are not repeated here, so that the positioning of each position point The more content contained in the information, the higher the positioning accuracy.
在本申请上述实施方式中,指纹信息以及目标定位信息的最小粒度为SrvNR的第一SSB信息(即至少包括N个第一SSB-ID以及对应的N个第一SSB-PSRP)和/或CSI-RS信息(即至少包括P个CSI-RS ID以及对应的P个CSI-RS RSRP),这就使得指纹库的数据更为详细和广泛,这与2G、3G、4G、WiFi等单纯利用小区ID和RSS来构建指纹,粒度更小,可获得的指纹库定位精度更高,并且可以解决5G场景下的单站(即只有一个NR)定位。In the foregoing embodiments of this application, the minimum granularity of fingerprint information and target location information is the first SSB information of SrvNR (that is, at least including N first SSB-IDs and corresponding N first SSB-PSRPs) and/or CSI -RS information (that is, including at least P CSI-RS IDs and corresponding P CSI-RS RSRPs), which makes the data of the fingerprint database more detailed and extensive, which is the same as 2G, 3G, 4G, WiFi and other simple use of cell ID and RSS are used to construct fingerprints, the granularity is smaller, the available fingerprint library positioning accuracy is higher, and it can solve the single-site (that is, only one NR) positioning in the 5G scenario.
需要说明的是,该指纹库除了可以利用SrvNR的第一SSB信息和/或CSI-RS信息定位之外,还可以联合NeighNR的第二SSB信息一起定位,以进一步提高定位精度,因此该指纹库还可以进一步包括:一个或多个NeighNR对应的邻小区ID及对应NeighNR的第二SSB信息(即包含第二SSB-ID、第二SSB-PSRP、第二SSB-RSRQ及第二SSB-SINR中的至少一个)。It should be noted that, in addition to positioning using the first SSB information and/or CSI-RS information of SrvNR, the fingerprint library can also be combined with NeighNR's second SSB information to further improve the positioning accuracy. Therefore, the fingerprint library It may further include: one or more neighbor cell IDs corresponding to NeighNR and second SSB information corresponding to NeighNR (that is, including the second SSB-ID, the second SSB-PSRP, the second SSB-RSRQ, and the second SSB-SINR At least one of).
在本申请上述实施方式中,指纹信息以及目标定位信息的最小粒度为SrvNR的第一SSB信息(即至少包括N个第一SSB-ID以及对应的N个第一SSB-PSRP)和NeighNR的第二SSB信息(即至少包括M个第二SSB-ID以及对应的M个第二SSB-PSRP),还可以包括CSI-RS信息(即至少包括P个CSI-RS ID以及对应的P个CSI-RS RSRP),相比上述单站定位,指纹粒度又更小,并且相比2G、3G、4G、WiFi等单站场景只有一个小区ID和一个小区RSS指纹区分度更高,定位精度也更高。In the above-mentioned embodiments of this application, the smallest granularity of fingerprint information and target location information is the first SSB information of SrvNR (that is, at least including N first SSB-IDs and corresponding N first SSB-PSRPs) and NeighNR Two SSB information (that is, at least M second SSB-IDs and corresponding M second SSB-PSRPs), and CSI-RS information (that is, at least P CSI-RS IDs and corresponding P CSI-RS- RS RSRP), the fingerprint granularity is smaller than the above single-site positioning, and compared with single-site scenarios such as 2G, 3G, 4G, WiFi, etc., there is only one cell ID and one cell RSS fingerprint. The discrimination is higher, and the positioning accuracy is also higher. .
还需要说明的是,该指纹库事先构建于该定位平台。定位平台获取到目标定位信息后,会将该目标定位信息与指纹库中的指纹信息一一比对,直到匹配上对应的目标指纹信息,之后定位平台根据该目标指纹信息确定对应的目标已知位置信息,进一步就可确定该目标已知位置信息为UE所处的目标位置。这里需要注意的是,如何根据指纹库进行定位的算法有多种实现方式,可以采用业内经典定位算法,具体此处不做限定。It should also be noted that the fingerprint library is built on the positioning platform in advance. After the positioning platform obtains the target positioning information, it will compare the target positioning information with the fingerprint information in the fingerprint database until the corresponding target fingerprint information is matched. Then the positioning platform determines the corresponding target according to the target fingerprint information. The location information can further determine that the known location information of the target is the target location where the UE is located. It should be noted here that there are multiple implementation methods for the positioning algorithm based on the fingerprint database, and the industry classic positioning algorithm can be used, which is not limited here.
B、角度定位。B. Angle positioning.
首先定位平台根据配置信息确定波束信息,波束信息包括波束(Beam)个数以及每个波束所指向的角度,每个波束都对应有一个Beam-ID(也可称为BeamID),每个波束所指向的角度可以通过天线方向图获取,每个Beam-ID都可以唯一映射为一个SSB-ID(也可称为SSBID)或唯一映射为一个CSI-RS ID,该唯一映射的方式可以有多种,具体此处不做限定。示例性的,以BeamID唯一映射为SSBID为例,图7给出了一个NR下行八个波束的波束形状,图8给出了对应图7的八个波束的指向角度。并给出了对应图7、图8中BeamID与SSBID 的对应关系以及每个波束的指向角度,如表1所示:First, the positioning platform determines the beam information according to the configuration information. The beam information includes the number of beams and the angle at which each beam is pointed. Each beam corresponds to a Beam-ID (also known as BeamID). The pointing angle can be obtained through the antenna pattern. Each Beam-ID can be uniquely mapped to an SSB-ID (also known as SSBID) or uniquely mapped to a CSI-RS ID. The unique mapping method can be multiple , The specifics are not limited here. Exemplarily, taking the unique mapping of BeamID to SSBID as an example, FIG. 7 shows the beam shape of an NR downlink eight beams, and FIG. 8 shows the pointing angles of the eight beams corresponding to FIG. 7. And the corresponding relationship between BeamID and SSBID in Figure 7 and Figure 8 and the pointing angle of each beam are given, as shown in Table 1:
表1:BeamID、SSBID的对应关系以及每个Beam的指向角度Table 1: Correspondence between BeamID and SSBID and the pointing angle of each Beam
之后,该定位平台就可以根据该波束信息和该目标定位信息确定UE的角度信息,最后,根据角度信息和事先获取到的UE与对应的SrvNR的距离信息确定UE所处的目标位置。需要说明的是,定位平台事先获取到的该UE与对应SrvNR的距离信息可以通过多种方式测量得到,具体此处不做限定。例如,可以基于TA和/或PA等得到。这里还需要说明的是,定位平台利用角度定位可以是只利用SrvNR进行角度定位,也可以是SrvNR联合和NeighNR一起进行角度定位,具体此处不做限定。以下示例几种角度定位的具体实施方式:After that, the positioning platform can determine the angle information of the UE according to the beam information and the target positioning information, and finally, determine the target position of the UE according to the angle information and the distance information between the UE and the corresponding SrvNR obtained in advance. It should be noted that the distance information between the UE and the corresponding SrvNR obtained in advance by the positioning platform can be measured in a variety of ways, and the details are not limited here. For example, it can be obtained based on TA and/or PA. It should also be noted here that the angular positioning of the positioning platform may be only the use of SrvNR for angular positioning, or the combination of SrvNR and NeighNR for angular positioning, which is not specifically limited here. The following examples illustrate several specific implementations of angular positioning:
1)定位平台仅利用SrvNR进行角度定位。1) The positioning platform only uses SrvNR for angular positioning.
当定位平台仅利用SrvNR进行角度定位时,上述波束信息就为该UE所处SrvNR下行波束的第一波束信息,上述角度信息也就为UE相对于该SrvNR的第一角度信息。具体的,当目标定位信息为服务小区ID以及第一SSB信息时,那么定位平台可以根据第一波束信息和第一SSB信息将每个第一SSB-ID都唯一映射为一个对应的第一Beam-ID,从0开始标记,最大标记为N-1,N为大于等于1的正整数,同时将第一SSB-RSRP对应修改为第一Beam-RSRP,假设第一SSB信息中SSB-ID有八个(即N=8),则第一SSB-ID、第一Beam-ID、第一SSB-RSRP以及第一Beam-RSRP的关系如下表2所示:When the positioning platform only uses SrvNR for angular positioning, the above beam information is the first beam information of the SrvNR downlink beam where the UE is located, and the above angle information is also the first angle information of the UE relative to the SrvNR. Specifically, when the target positioning information is the serving cell ID and the first SSB information, the positioning platform can uniquely map each first SSB-ID to a corresponding first beam according to the first beam information and the first SSB information -ID, marked from 0, the maximum mark is N-1, N is a positive integer greater than or equal to 1, and the first SSB-RSRP is correspondingly modified to the first Beam-RSRP, assuming that the SSB-ID in the first SSB information has Eight (ie N=8), the relationship between the first SSB-ID, the first Beam-ID, the first SSB-RSRP and the first Beam-RSRP is shown in Table 2 below:
表2:第一SSB-ID、第一Beam-ID、第一SSB-RSRP以及第一Beam-RSRP的映射关系Table 2: The mapping relationship of the first SSB-ID, the first Beam-ID, the first SSB-RSRP and the first Beam-RSRP
之后,定位平台将该第一波束信息、第一Beam-ID以及第一Beam-RSRP根据预设算法确定UE的角度信息。在本申请实施例中,如图9所示,可以基于但不限于如下公式计算UE相对SrvNR的角度信息:After that, the positioning platform determines the angle information of the UE according to the preset algorithm based on the first beam information, the first Beam-ID, and the first Beam-RSRP. In the embodiment of the present application, as shown in FIG. 9, the angle information of the UE relative to the SrvNR can be calculated based on but not limited to the following formula:
其中, 为该UE相对SrvNR的角度, 为N个波束在天线方向图中的角度, 具体的角度数据可以根据天线方向图计算得到(如图8中示意的天线方向图), 为对应SrvNR的公参小区方位角,可以通过配置信息中的NR工程参数获取,P scaleNorm可以为所有波束(即N个波束)预处理之后的数据。例如,P scaleNorm可以是通过能量归一化处理之后的数据,也可以是基于其他估算算法(如波束子空间估算算法、随机森林回归法等)对所有N个波束处理之后的数据,具体此处不做限定。 among them, Is the angle of the UE relative to SrvNR, Is the angle of the N beams in the antenna pattern, The specific angle data can be calculated according to the antenna pattern (the antenna pattern as shown in Figure 8), The azimuth angle of the common reference cell corresponding to the SrvNR can be obtained through the NR engineering parameters in the configuration information, and P scaleNorm can be data preprocessed by all beams (ie, N beams). For example, P scaleNorm can be the data processed by energy normalization, or it can be the data processed by all N beams based on other estimation algorithms (such as beam subspace estimation algorithm, random forest regression method, etc.), specifically here Not limited.
最后,根据上述公式计算得到的UE相对SrvNR的角度信息和定位平台事先获取到的UE与对应SrvNR的距离信息确定UE所处的目标位置。Finally, the target position of the UE is determined according to the angle information of the UE relative to the SrvNR calculated by the above formula and the distance information between the UE and the corresponding SrvNR obtained in advance by the positioning platform.
需要说明的是,当目标定位信息为服务小区ID以及CSI-RS信息时,定位平台获取UE相对SrvNR的角度信息与上述类似,具体此处不予赘述。It should be noted that when the target positioning information is the serving cell ID and the CSI-RS information, the acquisition of the UE's angle information relative to the SrvNR by the positioning platform is similar to the above, and the details are not repeated here.
在本申请上述实施方式中,首先将UE中MR的第一SSB信息映射为波束信息,结合SrvNR下行每个波束的指向角度可以精确估计UE相对SrvNR的方向。2G、3G、4G等场景小区覆盖范围宽广,单纯利用MR中的小区信息预测方位角误差大。而在5G场景下,NR下行覆盖被划分为多个波束,每个波束所覆盖的区域范围小,且波束所覆盖的角度固定,就可利用MR中的SSB-ID和SSB-RSRP(或利用CSI-RS ID和CSI-RS RSRP)间接计算UE相对NR的角度。预测角度更精准,定位精度更高。In the foregoing implementation manners of the present application, the first SSB information of the MR in the UE is first mapped to beam information, and the direction of each beam of the SrvNR downlink can be combined to accurately estimate the direction of the UE relative to the SrvNR. 2G, 3G, 4G and other scenarios have a wide coverage of cells, and the azimuth error is large to predict by simply using cell information in MR. In the 5G scenario, the NR downlink coverage is divided into multiple beams. The area covered by each beam is small and the angle covered by the beam is fixed. The SSB-ID and SSB-RSRP in MR can be used (or use CSI-RS ID and CSI-RS RSRP) indirectly calculate the UE relative NR angle. The prediction angle is more accurate and the positioning accuracy is higher.
2)定位平台利用SrvNR和NeighNR进行角度定位。2) The positioning platform uses SrvNR and NeighNR for angular positioning.
在本申请实施方式中,目标定位信息除了包括服务小区ID、第一SSB信息(或CSI-RS信息)之外,还包括邻小区ID、第二SSB信息,波束信息除了包括SrvNR下行波束的第一波束信息之外,还包括NeighNR下行波束的第二波束信息,角度信息除了包括UE相对于SrvNR的第一角度信息之外,还包括该UE相对于NeighNR的第二角度信息。In the embodiments of this application, the target positioning information includes not only the serving cell ID and the first SSB information (or CSI-RS information), but also the neighbor cell ID and the second SSB information. The beam information includes the second SrvNR downlink beam. In addition to the beam information, it also includes the second beam information of the NeighNR downlink beam. In addition to the first angle information of the UE relative to the SrvNR, the angle information also includes the second angle information of the UE relative to the NeighNR.
首先,定位平台基于第一SSB信息或CSI-RS信息估算UE相对SrvNR的第一角度信息,定位平台基于第一SSB信息或CSI-RS信息估算UE相对SrvNR的第一角度信息与上述类似,此处不予赘述。之后,定位平台基于第二SSB信息估算UE相对NeighNR的第二角度信息,具体的估算方法可以是:First, the positioning platform estimates the first angle information of the UE relative to the SrvNR based on the first SSB information or CSI-RS information, and the positioning platform estimates the first angle information of the UE relative to the SrvNR based on the first SSB information or CSI-RS information, which is similar to the above. I will not repeat it here. After that, the positioning platform estimates the second angle information of the UE relative to NeighNR based on the second SSB information. The specific estimation method may be:
定位平台根据第二波束信息和第二SSB信息将每个第二SSB-ID都唯一映射为一个对应的第二Beam-ID,从0开始标记,最大标记为M-1,M为大于等于1的正整数,同时将第二SSB-RSRP对应修改为第二Beam-RSRP,假设第二SSB信息中SSB-ID有两个(即M=2),则第二SSB-ID、第二Beam-ID、第二SSB-RSRP以及第二Beam-RSRP的关系如下表3所示:The positioning platform uniquely maps each second SSB-ID to a corresponding second Beam-ID according to the second beam information and the second SSB information, starting from 0, marking the maximum mark as M-1, and M being greater than or equal to 1. At the same time, the second SSB-RSRP is correspondingly modified to the second Beam-RSRP. Assuming that there are two SSB-IDs in the second SSB information (ie M=2), then the second SSB-ID and the second Beam- The relationship among ID, second SSB-RSRP, and second Beam-RSRP is shown in Table 3 below:
表3:第二SSB-ID、第二Beam-ID、第二SSB-RSRP以及第二Beam-RSRP的映射关系Table 3: The mapping relationship between the second SSB-ID, the second Beam-ID, the second SSB-RSRP, and the second Beam-RSRP
之后,定位平台根据该第二波束信息、第二Beam-ID以及第二Beam-RSRP根据预设算法确定UE相对NeighNR的第二角度信息。在本申请实施例中,如图10所示,可以基于但不限于如下公式计算UE相对NeighNR的第二角度信息:After that, the positioning platform determines the second angle information of the UE relative to the NeighNR according to the second beam information, the second Beam-ID, and the second Beam-RSRP according to a preset algorithm. In the embodiment of the present application, as shown in FIG. 10, the second angle information of the UE relative to the NeighNR can be calculated based on but not limited to the following formula:
其中, 为该UE相对NeighNR的角度, 为M个波束在天线方向图中的第二角度, 具体的角度数据可以根据天线方向图计算得到(如图8中示意的天线方向图), 为对应NeighNR的公参小区方位角,可以通过配置信息中的NR工程参数获取,P scaleNorm可以为所有波束(即M个波束)预处理之后的数据。例如,P scaleNorm可以是通过能量归一化处理之后的数据,也可以是基于其他估算算法(如波束子空间估算算法、随机森林回归法等)对所有M个波束处理之后的数据,具体此处不做限定。 among them, Is the angle of the UE relative to NeighNR, Is the second angle of the M beams in the antenna pattern, The specific angle data can be calculated according to the antenna pattern (the antenna pattern as shown in Figure 8), The azimuth angle of the common reference cell corresponding to NeighNR can be obtained through the NR engineering parameter in the configuration information, and P scaleNorm can be data after preprocessing of all beams (ie, M beams). For example, P scaleNorm can be the data processed by energy normalization, or it can be data processed by all M beams based on other estimation algorithms (such as beam subspace estimation algorithm, random forest regression method, etc.). Not limited.
需要注意的是,如果NeighNR只有一个波束,则估算的UE相对NeighNR的第二角度信息可以按照如下方式得到:It should be noted that if NeighNR has only one beam, the estimated second angle information of the UE relative to NeighNR can be obtained as follows:
需要说明的是,在图10中,仅示意出了一个NeighNR,实际上NeighNR可以有多个,UE针对每一个NeighNR的角度信息都可以利用上述方式获取,最后根据上述公式计算得到的UE相对每一个NeighNR的第二角度信息,并结合已计算得到的UE相对SrvNR的第一角度信息,同时利用定位平台事先获取到的UE与对应的SrvNR的距离信息就确定UE所处的目标位置。It should be noted that in Figure 10, only one NeighNR is shown. In fact, there can be multiple NeighNRs. The UE's angle information for each NeighNR can be obtained in the above manner. Finally, the UE calculated according to the above formula is relative to each The second angle information of a NeighNR is combined with the calculated first angle information of the UE relative to the SrvNR, and the distance information between the UE and the corresponding SrvNR obtained in advance by the positioning platform is used to determine the target location of the UE.
需要说明的是,由于UE中的MR无法获取NeighNR的CSI-RS信息,也就是说目标定位信息中不包含NeighNR的CSI-RS信息,因此UE相对NeighNR的第二角度信息只能基于第二SSB信息获取。It should be noted that since the MR in the UE cannot obtain the CSI-RS information of NeighNR, that is, the target positioning information does not contain the CSI-RS information of NeighNR, so the second angle information of the UE relative to NeighNR can only be based on the second SSB Access to information.
在本申请上述实施方式中,5G场景下定位平台基于第一SSB信息或CSI-RS信息获取到UE相对于SrvNR的第一角度信息之后,还可以进一步计算得到UE相对于NeighNR的第二角度信息,利用多个角度信息定位UE的目标位置,定位精度更高。In the foregoing embodiments of this application, after the positioning platform in the 5G scenario obtains the first angle information of the UE relative to the SrvNR based on the first SSB information or the CSI-RS information, it can further calculate the second angle information of the UE relative to NeighNR. , Using multiple angle information to locate the target position of the UE, with higher positioning accuracy.
还需要说明的是,在本申请的一些实施方式中,定位平台根据目标定位信息和配置信息确定UE所处的目标位置之后,还可以进一步将该目标位置发送至UE,以使得UE可以随时获知自身所处的目标位置,提高用户使用体验。It should also be noted that in some embodiments of the present application, after the positioning platform determines the target position of the UE according to the target positioning information and configuration information, it may further send the target position to the UE so that the UE can know at any time The target location of oneself can improve the user experience.
本申请实施例可以根据上述定位方法示例对定位平台以及UE进行功能模块的划分,例如,可以对应各个功能划分各个功能模块,也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现,也可以采用软件功能模块的形式实现。需要说明的是,本申请实施例中对模块的划分是示意性的,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式。The embodiment of the present application may divide the positioning platform and the UE into functional modules according to the above positioning method examples. For example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The above-mentioned integrated modules can be implemented in the form of hardware or software functional modules.
