为便于更好的理解本申请实施例,对本申请相关的定位技术进行说明。
位置是日常生活中不可或缺的应用之一,大家对于定位的延迟和准确性要求也越来越严格。在许多定位应用中,精确定位通常是通过多种技术的组合来实现的。比如,1、基于全球导航卫星系统(Global Navigation Satellite System,GNSS)提供户外场景中的位置信息;2、无线电技术(例如LTE网络,提供多种选项来定位用户,无线网络,地面信标系统,等等);3、惯性测量单元(Inertial Measurement Units,IMU)或传感器(例如基于加速计追踪用户位置、陀螺仪、磁力仪或利用大气压力传感器进行垂直定位)。这些技术都有望在未来实现准确的用户定位方面发挥重要作用。
第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)新空口(New Radio,NR)系统的增强定位能力带来额外的增益。低频段和高频段(即FR1和FR2)的操作和大量天线阵列的使用提供了额外的自由度,大大提高了定位精度。基于观测到达时间差(Observed Time Difference of Arrival,OTDOA)和上行到达时间差(Uplink Time Difference of Arrival,UL-TDOA)、小区标识(Cell-ID)或增强的小区标识(E-Cell-ID)等定位技术,利用大带宽(低频段以及高频段)进行时间测量为用户定位带来了更好的性能。利用大规模(massive)天线系统(如多入多出(multiple in multiple out,MIMO)),通过结合时间测量以及传播信道的空间和角度域来实现更准确的用户位置。
版本15(release15,Rel-15)NR定位课题定义了Cell-ID(包括部分小区标识)以及基于长期演进定位协议(Evolution Positioning Protocol,LPP)的独立的(independent)无线接入技术(Radio Access Technology,RAT)(RAT-independent)定位方法。版本16(release16,Rel-16)主要研究NR独立布网(standalone)RAT-dependent定位方法,包括下行到达时间差(Downlink Time Difference of Arrival,DL-TDOA),下行离开角(Downlink Angle of Departure,DL-AoD),UL-TDOA,上行离开角(Uplink Angle of Departure,UL-AoD),往返传输时间(Round Trip Time,RTT)以及E-Cell-ID等。
3GPP R17的定位项目主要考虑从提高精度,降低时延以及提高终端侧和网络侧效率这几个方面来增强定位方法以及相关的参考信号。
为了提高效率,降低时延以及提高定位精度,R17NR定位(positioning)提出了一种增强,按需PRS(on-demand PRS),主要增益包括以下几方面:
效率(Efficiency),按需下行PRS(DL-PRS)避免了在特定时间或网络特定区域不需要终端设备定位的情况下不必要的开销、能源浪费等。在波束形成的DL-PRS的情况下,在所有波束扫描方向上的DL-PRS传输可能导致DL-PRS的不必要传输。
延迟(Latency),当前的DL-PRS配置可能不足以满足位置服务(Location Services,LCS)客户端的响应时间要求;例如,周期性可能太大。
精度(Accuracy),当前的DL-PRS配置可能不足以满足LCS客户端的精度要求;例如,可能带宽太小,重复次数太少等。
为便于更好的理解本申请实施例,对本申请相关的下行定位参考信号进行说明。
下行定位参考信号主要包括PRS,在Rel-16中,PRS是由LMF实体统一配置并由LPP消息发送给终端设备。具体来说,各个基站(如gNB)或传输接收点(Transmission Reception Point,TRP)将自己可以发送的PRS配置上报给LMF实体,LMF实体协调多个gNB/TRP上报的PRS配置并基于这些配置生成最终的PRS配置信息发送给终端设备以及gNB/TRP。
由于不同终端以及不同的定位请求有不同的精度要求,统一配置的PRS配置可能无法满足个别终端以及个别应用对于精度的需求;另一方面,对于当前没有定位需求的终端,网络侧持续发送PRS也会带来额外的功耗开销。On-demand PRS的主要思想就是可以基于终端/LMF实体的需求来请求合适的PRS配置,使得网络侧在以最小发送功耗的基础上最大限度满足精度的需求。
在一些实现方式中,On-demand PRS的流程可以如图2所示。具体的,图2所示的On-demand PRS的流程可以包括如下步骤:
S11-a,终端设备发起按需PRS请求;
S11-b,LMF实体发起按需PRS请求;
S12-a,LMF实体向服务小区基站发送PRS配置更新请求;
S12-b,LMF实体向服务小区的邻小区基站发送PRS配置更新请求;
S13-a,服务小区基站向LMF实体发送PRS配置更新响应;
S13-b,服务小区的邻小区基站向LMF实体发送PRS配置更新响应;
S14,LMF实体向终端设备发送新的PRS配置信息。
需要说明的是,S11-a与S11-b可以仅执行其一,也可以同时执行。
在另一些实现方式中,上述图2中的基站也可以是TRP。
若终端设备或LMF实体发起了on-demand PRS请求,网络需要向每个gNB/TRP请求配置的修改以及更新,gNB/TRP收到请求后还需要一一反馈LMF实体,这无疑带来了额外的信令开销。为了解决此问题,本申请提出了一种激活/去激活on-demand PRS的方案。
以下通过具体实施例详述本申请的技术方案。
图3是根据本申请实施例的无线通信的方法200的示意性流程图,如图3所示,该方法200可以包括如下内容中的至少部分内容:
S210,LMF实体向至少一个接入网设备发送第一信息;其中,该第一信息用于指示激活目标PRS配置信息。
在本申请实施例中,在终端设备或LMF实体发起按需PRS(on-demand PRS)请求之后,LMF实体可以向至少一个接入网设备发送第一信息,以指示该至少一个接入网设备激活目标PRS配置信息。
在一些实施例中,在执行S210之前,LMF实体接收终端设备发送的请求信息,该请求信息用于请求按需进行PRS配置。也即,在执行S210之前,终端设备发起了按需PRS(on-demand PRS)请求。
在一些实现方式中,该请求信息包括当前业务类型或定位精度对应的PRS配置信息,或者,该请求信息包括当前业务类型或定位精度对应的PRS配置信息的索引。也即,终端设备可以基于当前业务类型或定位精度确定需要请求的PRS配置信息。
在一些实现方式中,在该请求信息包括当前业务类型或定位精度对应的PRS配置信息的索引的情况下,网络预配置了多套PRS配置信息及其对应的索引(index)给终端设备,从而,终端设备基于当前业务类型或定位精度的需求向网络请求相应的PRS配置对应的索引(index)。
在一些实现方式中,该请求信息可以包括所请求的PRS配置信息的具体参数,具体包括但不限于以下至少一种:
周期变化量(Changes to periodicity),例如周期的增加或减少量;

打开/关闭TRP/小区的某些PRS配置,或,去激活TRP/小区的某些PRS配置;例如在测量高干扰时,打开/关闭TRP/小区的某些PRS配置,或,去激活TRP/小区的某些PRS配置。
在一些实施例中,在执行S210之前,LMF实体发起按需PRS配置请求。也即,在执行S210之前,LMF实体发起了按需PRS(on-demand PRS)请求。
在本申请实施例中,LMF实体指示激活目标PRS配置信息之后,至少一个接入网设备无需针对激活指示进行响应,LMF实体也无需等待每个接入网设备发送的反馈,避免了终端设备、LMF实体、接入网设备之间不必要的信令开销,从而优化通信系统性能。
在一些实施例中,该至少一个接入网设备包括以下至少之一:
终端设备的服务小区内的基站、终端设备的服务小区内的TRP、终端设备的服务小区的邻小区内的基站、终端设备的服务小区的邻小区内的TRP。

需要说明的是,网络预配置了多套PRS配置信息及其对应的索引(index)给至少一个接入网设备,此种情况下,LMF实体向至少一个接入网设备发送的第一信息中可以包括该目标PRS配置信息的索引,该至少一个接入网设备可以基于该目标PRS配置信息的索引获取或识别对应的目标PRS配置信息。
在一些实施例中,该LMF实体向终端设备发送第二信息,其中,该第二信息包括该目标PRS配置信息或该目标PRS配置信息的索引。从而,终端设备可以获知LMF实体确定激活的PRS配置信息或PRS配置信息的索引,基于激活的PRS配置信息进行PRS测量,以及基于PRS测量结果进行定位估计。
其中,该第二信息可以是针对按需PRS(on-demand PRS)请求的响应。
需要说明的是,网络预配置了多套PRS配置信息及其对应的索引(index)给终端设备,此种情况下,LMF实体向终端设备发送的第二信息中可以包括该目标PRS配置信息的索引,终端设备可以基于该目标PRS配置信息的索引获取对应的目标PRS配置信息。
在一些实施例中,在执行S210之前,LMF实体可以基于至少一个接入网设备支持的PRS能力或配置,给终端设备和/或至少一个接入网设备预配置多套PRS配置信息及其对应的索引(index)。具体地,可以通过如下步骤实现:
该LMF实体获取该至少一个接入网设备支持的PRS能力或配置;
该LMF实体根据该至少一个接入网设备支持的PRS能力或配置,生成多个PRS配置信息和该多个PRS配置信息的索引;
该LMF实体向该至少一个接入网设备发送第三信息,和/或,该LMF实体向终端设备发送第三信息,其中,该第三信息用于指示该多个PRS配置信息和该多个PRS配置信息的索引。
也即,在本申请实施例中,终端设备、接入网设备(如基站或TRP)、LMF实体三方可以基于PRS能力或配置进行协调,以预配置多套PRS配置信息及其对应的索引。
在一些实施例中,在执行S210之后,该LMF实体接收该至少一个接入网设备发送的第四信息;其中,该第四信息用于指示拒绝激活该目标PRS配置信息,或者,该第四信息用于指示更新该至少一个接入网设备支持的PRS能力或配置。
需要说明的是,该第四信息用于指示拒绝激活该目标PRS配置信息,也即,该至少一个接入网设备拒绝激活LMF实体指示激活的目标PRS配置信息。此种情况下,可能是目标PRS配置信息发生了变更,或者,目标PRS配置信息不是优选的PRS配置信息。
在一些实施例中,在该第四信息用于指示更新该至少一个接入网设备支持的PRS能力或配置的情况下,该LMF实体需要重新生成PRS配置信息,以及将新的PRS配置信息及其对应的索引指示给终端设备和该至少一个接入网设备。
因此,在本申请实施例中,在终端设备或LMF实体发起On-demand PRS请求之后,LMF实体可以激活目标PRS配置信息,无需等待每个基站或TRP发送的PRS配置更新反馈,避免了终端设备、LMF实体、基站或TRP之间不必要的信令开销,从而优化通信系统性能。
