具体实施方式
下面将参照附图来说明本发明的实施例。在本发明的一个附图或一种实施方式中描述的元素和特征可以与一个或更多个其它附图或实施方式中示出的元素和特征相结合。应当注意，为了清楚的目的，附图和说明中省略了与本发明无关的、本领域普通技术人员已知的部件和处理的表示和描述。
如图1所示，根据本实施例的用于无线通信的电子装置100包括处理电 路110。处理电路110例如可以实现为特定芯片、芯片组或者中央处理单元(CPU)等。
处理电路110包括范围确定单元111和配置确定单元113。需要指出，虽然附图中以功能块的形式示出了范围确定单元111和配置确定单元113，然而应理解，各单元的功能也可以由处理电路作为一个整体来实现，而并不一定是通过处理电路中分立的实际部件来实现。另外，虽然图中以一个框示出处理电路，然而电子装置可以包括多个处理电路，并且可以将各单元的功能分布到多个处理电路中，从而由多个处理电路协同操作来执行这些功能。
根据本实施例的电子装置100可以被设置在基站侧，并且可以工作为位置管理模块(Location Management Function，LMF)。LMF用于新无线(New Radio，NR)中的移动位置管理，其接收定位需求，并分配定位任务，也可进行位置计算。
定位请求可以在用户侧或网络侧发起。若在用户侧发起，例如，控制平面的接入管理模块(AMF，Access Management Function)收到用户发来的定位请求后，将定位请求相关信息转发给定位服务系统，例如NR中的LMF。定位服务系统完成相关定位操作后将得到的定位信息反馈给AMF，AMF再将信息发送给提出请求的实体。在某些情况下，AMF也可以自己发出定位请求，并要求定位服务系统完成操作。
传统移动通信系统如长期演进(LTE)中的定位采用基于传播延时测量的观察到达时间差(Observed Time Difference Of Arrival，OTDOA)技术，由于LTE使用多天线技术支持最多8天线的TRP配置，还没有应用大规模多天线(Massive MIMO)技术，因此不能形成高度方向性高增益的窄波束。在NR中，采用进行数据传输的波束扫描，5G大规模天线技术可以形成高增益的窄波束，可以用波束的角度信息来实现高精度定位。
在定位方式方面，LTE通信系统使用OTDOA技术通过测量到达时间差来计算用户设备(UE)位置。在波束扫描方面，5G中对于信号传输的波束扫描的最小波束角度受限于基站天线数和基站天线的拓扑结构，且随着波束传播距离的增加，波束增益按指数级减小，波束覆盖范围显著增大从而导致定位位置的误差范围变大。
LTE中使用的OTDOA技术的定位精度十分受限，特别是垂直方向上误差较大。在不同场景下OTDOA(精确同步)垂直方向定位精度最好也要超过10米，水平定位精度在米级以上。NR中若使用波束扫描进行定位，由于 波束的传播特性和基站天线阵列规模限制，对于很多用户特别是离主定位基站距离较远的用户，其能够获得的定位精度不能满足NR定位精度要求。下面在单TRP波束扫描定位场景进行简单计算：假设最窄波束角度为4°，NR定位精度要求为0.5m，若想达到该定位精度，计算得到待定位UE到TRP的距离不能超过7m。虽然多TRP协作波束扫描定位可以提高定位精度，但最终精度仍然受限于最窄波束角度(TRP天线配置)，对于离TRP较远的UE，定位精度更差。
继续参照图1，根据本实施例的电子装置100的范围确定单元111被配置为基于UE关于第一波束扫描的第一测量信息，确定UE的第一位置范围。
配置确定单元113被配置为基于第一位置范围确定波束配置的调整。根据一个实施例，配置确定单元113可以仅在第一位置范围低于预定的精度要求时确定波束配置的调整。
范围确定单元111还被配置为基于UE关于利用经调整的波束配置进行的第二波束扫描的第二测量信息，确定UE的第二位置范围。
根据一个实施例，波束配置可以包括波束方向或波束宽度或波束方向和波束宽度两者。
根据一个实施例，第一位置范围和第二位置范围的确定可以基于UE接收到的最强波束的发射角，或者可以基于最强波束的发射角以及最强波束的接收功率两者。
根据一个实施例，第一测量信息和第二测量信息可以包括UE通过测量波束扫描中各波束的接收功率而确定的具有最大接收功率的波束的信息。
根据一个实施例，波束配置的调整可以包括调整波束方向以使得相邻波束分割第一位置范围。例如，可以将波束方向旋转一定角度，使得相邻波束的分界线分割第一位置范围。
更具体地，波束配置的调整可以包括使得经调整的相邻两个波束平分第一位置范围，例如使得经旋转的相邻两个波束的分界线平分第一位置范围或穿过第一位置范围的中心点。或者，波束配置的调整可以包括使得经调整的(例如经旋转的)波束对第一位置范围分割后所有子区域中的最大面积最小化。
此外，波束配置的调整还可以包括调整波束方向和宽度，使得经调整的(例如经旋转的)相邻波束覆盖第一位置范围。
另外，第二测量信息可以包括通过UE对经调整的(例如经旋转的)至少两个相邻波束进行测量而确定的具有最大接收功率的波束的信息。
图2示出了根据另一个实施例的用于无线通信的电子装置的配置示例。
如图2所示，电子装置200包括处理电路210，处理电路210包括范围确定单元211和配置确定单元213，其分别与前面参照图1描述的范围确定单元111和配置确定单元113类似。此外，处理电路210还包括集合确定单元215。
集合确定单元215被配置为确定无线接入点的第一收/发端(TRP)集合，用于基于第一波束配置进行第一波束扫描。集合确定单元215还被配置为基于第一测量信息确定无线接入点的第二收/发端集合，用于基于第二波束配置进行第二波束扫描。第一收/发端集合和第二收/发端集合分别包括一个或更多个收/发端电路。
根据一个实施例，集合确定单元215可以被配置为将与UE所在小区的主无线接入点邻近的无线接入点的收/发端确定为第一收/发端集合。或者，集合确定单元215可以被配置为根据无线接入点接的收/发端收到UE发送的上行信号的强度确定第一收/发端集合，例如将信号强度高的收/发端确定为第一收/发端集合。

图3示出了根据另一个实施例的用于无线通信的电子装置的配置示例。
如图3所示，电子装置300包括处理电路310，处理电路310包括范围确定单元311和配置确定单元313，其分别与前面参照图1描述的范围确定单元111和配置确定单元113类似。此外，处理电路310还包括精度确定单元315。
精度确定单元315被配置为确定第二位置范围是否满足定位精度要求。在第二位置范围不满足定位精度要求的情况下，可以通过配置确定单元313 进一步确定波束配置的调整。
根据一个实施例，精度确定单元315可以基于以下条件中的一项或更多项确定第二位置范围是否满足定位精度要求：第二位置范围的最大偏移小于定位精度要求的位置偏移；第二位置范围的面积小于定位精度要求的位置不确定面积；以及第二位置范围的各方向加权平均位置偏移小于定位精度要求的加权平均位置偏移。精度确定单元315可以以类似的方式确定第一位置范围是否满足定位精度要求。
接下来，结合具体示例说明根据本发明实施例的波束定位的示例过程。需要指出，在下述示例中包含了本发明上述实施例的多个方面。
图7示出了作为本发明示例实施例的基于旋转波束的基站协作定位的示例过程。
在该协作定位过程中，首先选择初始TRP集合进行波束扫描，确定UE的初始位置范围。接下来，可选地，根据初始位置范围以及定位精度需求，选择新的TRP集合并协作计算各TRP的波束旋转角度和方向。各TRP在确定的波束旋转角度方向上顺序发送两个波束。通过UE反馈波束测量值，在初始位置范围内确定UE的精度位置。最后根据UE定位精度要求，确定是否完成定位。
更具体地，如图7所示，该过程可以相应于UE的定位请求(S701)而开始。此后，基于系统配置，可以在各单元见进行参数交换(S703)。
在S705，主TRP/LMF选定初始TRP集合进行波束扫描，计算初始集合中各TRP的波束宽度。
然后，主TRP/LMF可以将波束宽度下发给初始集合中各TRP并通知各TRP进行波束扫描和UE进行测量(S707)。
接下来，在S709，UE进行波束定位过程，并且在S711将测量信息反馈上报给主TRP/LMF(或初始集合中各TRP)。
在S713，主TRP/LMF(或初始集合中各TRP协作)计算UE初始位置范围。
在S715，主TRP/LMF可以选择新的TRP集合进行旋转波束定位，主TRP/LMF(或新集合中各TRP协作)计算各TRP的波束旋转角度、方向和波束宽度。
若由主TRP/LMF计算，则主TRP/LMF将波束旋转角度等参数下发给新 集合中各TRP(S717)。
在S719，新的TRP集合中各TRP在初始位置范围内协作进行旋转波束定位。
在S721，UE将测量信息反馈上报给主TRP/LMF(或新集合中各TRP)。
在S723，主TRP/LMF(或新集合中各TRP协作)计算UE新的位置范围，并且主TRP或LMF可以根据UE定位精度要求，确定是否完成定位。
如果满足定位精度要求，即不需要进一步进行波束定位(S723中的“否”)，则在S725，将所确定的位置下发给UE。
如果不满足定位精度要求，即需要进一步进行波束定位(S723中的“是”)，则返回步骤S715重复进行定位过程。
接下来，将对根据本发明示例实施例的波束定位过程进行更具体的说明。
当UE定位请求到达LMF后(S701)，系统首先进入初始化阶段。
在S703，UE与LMF可以交换UE所在主TRP的类型、天线阵列形状、覆盖范围等信息。主TRP附近多个TRP也可以将上述信息报告给主TRP或LMF。例如，TRP类型可以是宏基站或小基站，天线阵列形状可以是平面阵列或均匀线性阵列(ULA)等不同拓扑形状。
主TRP或LMF收集完UE附近的多个TRP的信息之后，在S705，根据UE的定位需求，确定参与协作定位的TRP，组成初始TRP集合，并确定每个TRP进行波束扫描的波束宽度。
对于参与波束扫描的初始TRP集合的选择，也可以采用基于参考信号的实际测量方式。具体地，UE可以发送上行参考信号，主TRP附近的各个TRP通过该参考信号测量接收信号的功率等参数。主TRP或LMF在收到各个TRP反馈回来的测量功率值后，选择接收信号功率最强的几个TRP组成初始TRP集合。对于进行波束扫描的TRP具体个数以及各TRP的波束扫描宽度，可以根据定位精度、资源开销等因素而进行确定。
初始TRP集合选定之后，在S707，主TRP或LMF通知初始TRP集合中的各TRP同时进行波束扫描并下发各TRP波束扫描宽度，并且通知UE进行波束测量。
各TRP收到通知后，在S709，在选定的时隙上进行波束扫描。具体地，UE接收到来自初始TRP集合中各TRP波束扫描的波束，测量各波束的接收功率，并将对应各TRP的接收功率最大的波束编号以及最大接收功率上报给 主TRP/LMF或初始集合中各TRP(S711)。
图8示出了TRP的波束扫描过程示例。在该示例中，TRP1顺序发送4个波束，UE分别测量这4个波束的接收功率并找到接收功率最大的波束，例如将该波束编号及功率上报给主TRP或LMF。
返回参照图7，在S713，主TRP或LMF或初始集合中的各TRP可以根据UE上报的各TRP的最强波束以及对应接收功率计算UE位置范围。
在图9所示的示例中，实线指示UE上报的TRP1、TRP2和TRP3的最强波束的范围，其重叠区域即阴影斜线区域被确定为UE的位置范围。若该位置范围符合UE定位精度需求，则可以直接将位置报告给UE。若位置范围不符合UE定位精度需求，则需要进行后续步骤以进一步确定位置范围。
如前所述，位置范围的确定可以基于UE接收到的最强波束的发射角，或者可以基于最强波束的发射角以及最强波束的接收功率两者。
图10、图12和图14示出了基于最强波束的发射角以及最强波束的接收功率两者确定位置范围的示例。
在图10所示的示例中，单个TRP通过波束角度和接收功率的反馈计算UE位置范围，如图中UE2所在的阴影区域所示。
也可以基于针对多个TRP的波束角度和接收功率的反馈来计算UE位置范围。图12示出了基于3个TRP的波束角度和接收功率的反馈计算UE位置范围的示例。
此外，还可以通过宽波束角度和接收功率的反馈计算UE位置范围。图14示出了单个TRP进行宽波束扫描定位后的位置范围，如图中斜线区域所示。
图11和图13示出了基于最强波束的发射角确定位置范围的示例。
在图11所示的示例中，基于2个TRP的波束角度的反馈计算UE位置范围，如图中斜线区域所示。
此外，多个TRP可以进行不同宽度的波束扫描。图13示出了2个TRP进行宽波束扫描定位后的位置范围的示例。如图13所示,TRP 1和TRP 2的波束扫描宽度分别为α°和β°，波束扫描后的位置范围为斜线区域。
继续参照图7，基于在S713中计算的UE位置范围以及定位精度需求，在S715，主TRP/LMF选择用于进行旋转波束协作定位的TRP的数目及位置并将这些TRP加入新的TRP集合，并且主TRP/LMF或新集合中各TRP协 作计算各TRP的波束旋转角度、方向以及波束宽度。
作为示例，波束旋转角度、方向以及波束宽度的确定可以基于以下规则中的一项或更多项：
1)新集合中各TRP相邻两个旋转波束的分界线尽可能平分初始位置范围，或穿过初始位置范围的中心点；
2)新集合中所有TRP协作计算波束旋转角度和方向，使得所有旋转波束对初始位置范围分割后所有子区域中的最大面积最小化；以及
3)新集合中各TRP的相邻两个旋转波束的旋转方向和宽度选择需要覆盖初始位置范围。
图16示出了满足第1)准则的示例，其中TRP 3被主TRP或LMF选择来进行旋转波束定位，根据波束扫描流程之后计算得到的位置范围，并给定位置范围中心的点A，使得TRP 3在旋转波束定位的流程中发送的相邻两个波束的分界线穿过点A，从而得到波束旋转角度β°。主TRP或LMF将计算后的TRP 3的波束旋转角度通知给TRP 3并要求TRP 3进行旋转波束定位，同时通知UE准备进行旋转波束测量(S717)。
下面结合图16说明波束旋转角度计算的一个示例。
假设已用于波束扫描定位的TRP 1、TRP 2和TRP 3的坐标分别为(0,0)、(x2,y2)和(x3,y3)，TRP 1波束扫描阶段的最强波束方向为y轴，TRP 2的最强波束相对于x轴的角度为α°，点A为TRP 1和TRP 2最强波束方向的交点。主TRP或LMF选择TRP 3进行旋转波束定位，确定波束旋转角度的原则是：TRP 3旋转波束方向经过点A。因此，波束旋转角度β°可以按如下公式计算：
Figure PCTCN2019114743-appb-000001
继续参照图7，根据在S715计算出的波束旋转角度，在S719，各TRP针对位置范围分别顺序发送对应波束旋转角度的相邻两个波束，从而进行旋转波束定位。
再次参照图15，TRP 3根据计算出的波束旋转角度β°以及波束宽度，进行旋转波束定位，顺序发送对应于波束旋转角度β°的相邻两个波束。
图17至图19示出了旋转波束定位的示例方式。
在图17所示的示例中，TRP 1在被选择进行波束扫描定位(S709)之后又被选择进行旋转波束定位(S719)。在进行旋转波束定位时，TRP 1顺序发送由波束旋转角度确定的相邻两个波束。
在图18所示的示例中，TRP 1和TRP 2在被选择进行宽波束扫描定位(S709)之后，TRP 3被选择进行窄旋转波束定位(S719)。在进行窄旋转波束定位时，TRP 3向初始位置范围顺序发送由波束旋转角度确定的相邻多个波束。
在图19所示的示例中，单个TRP在被选择通过宽波束角度和接收功率进行宽波束扫描定位(S709)之后，又被选择进行窄旋转波束定位(S719)。在进行窄旋转波束定位时，该TRP向初始位置范围顺序发送由波束旋转角度确定的相邻多个波束。
继续参照图7，UE测量对应各TRP的相邻波束的接收功率，选出各TRP对应更大接收功率的波束，将最强波束编号和接收功率上报给主TRP/LMF或新集合中各TRP(S721)。主TRP/LMF或新集合中各TRP结合该最强波束与波束扫描阶段最强波束联合确定最强虚拟波束。主TRP/LMF或新集合中各TRP根据各TRP的最强虚拟波束以及接收功率协作计算新的位置范围(S723)。
如图20所示，“第一位置不确定性”区域和“第二位置不确定性”区域分别为波束扫描阶段的初始位置范围和旋转波束定位阶段的位置范围，将其重叠区域即“第三位置不确定性”区域确定为UE的位置范围。
在S723中，在计算出UE新的位置范围后，根据UE的定位精度需求，主TRP或LMF可以判断是否完成定位。若新的位置范围符合UE定位精度需求，则主TRP或LMF可以直接将位置报告给UE(S725)；若新的位置范围不符合UE定位精度需求，则返回S715继续进行旋转波束定位。
主TRP或LMF对是否完成定位的判断可以基于计算出的新的位置范围和定位精度要求，并且可以基于以下要求中的一项或更多项：
1)位置范围的最大偏移小于定位精度要求的位置偏移；
2)位置范围的面积小于定位精度要求的位置不确定面积；以及
3)位置范围的各方向加权平均位置偏移小于定位精度要求的加权平均位置偏移。
关于要求1)，再次参照图18进行具体说明。图18示出了为在TRP 1、 TRP 2被选择进行宽波束扫描定位之后，TRP 3被选择进行窄旋转波束定位。在进行窄旋转波束定位时，TRP 3向初始位置范围顺序发送由波束旋转角度确定的相邻多个波束。在TRP 3完成旋转波束定位之后，TRP协作计算新的位置范围如图中“第二位置不确定性”区域所示。
基于该位置范围，可以计算得到最大偏移为“第二位置不确定性”区域中的虚线对角线所示，假设新的位置范围的最大偏移(虚线对角线)为3m，而定位精度要求的位置偏移为5m，则该位置范围满足定位精度要求，直接将位置报告给UE，定位流程结束。
下面参照图21进一步说明该步骤。
假设同一个TRP先后被选择进行宽波束扫描定位和窄旋转波束定位，宽波束定位后的初始位置范围如图中“第一位置不确定性”区域所示，窄旋转波束定位后新的位置范围如图中“第二位置不确定性”区域所示。假设“第二位置不确定性”区域的位置范围仍然不满足UE定位精度要求，主TRP或LMF需要继续选择新的TRP集合做旋转波束定位。若同一个TRP被选择进行旋转波束定位，最后计算得到图中“第三位置不确定性”区域为新的位置范围，且满足UE定位精度要求，则将该位置范围下发给待定位的UE。
需要指出，本发明不限于上述示例中的具体细节。

使得定位精度不受基站天线数(波束角度分辨率)限制；
使得远距离定位精度显著提高；
