为了理解本申请实施例,对本申请相关的定位辅助信息进行说明。
定位辅助信息中包含终端设备需要执行测量的下行位置参考信号(positioning reference signals,PRS)配置。不同的PRS配置是绑定在给定范围内的传输点TRP和给定频带上的,即不同位置上的TRP具有不同的PRS配置。这样,通过测量不同位置的TRP发送的不同的PRS,终端设备可以确定与不同TRP的相对位置或者相对角度,进而用于终端设备的定位。因为电磁波衰落的本身特性,随着终端设备离PRS信号作用的区域越来越远,来自给定TRP的PRS信号强度逐渐变小,从而无法为定位功能提供有效帮助。反之,如果终端设备始终在给定区域里移动,那么终端设备接收到的定位辅助信息也应该是有效的(只要TRP没有结束PRS信号的发送)。
在一些场景中,为定位辅助信息引入了相应的有效区域的概念。
首先,网络设备将预配置的定位辅助信息和相应的有效区域(由小区列表所定义)发送至终端设备。在后续每一次定位会话到来时,终端设备判断当前驻留小区是否属于有效区域内。如果属于有效区域内,终端设备则可以直接应用之前获得的定位辅助信息,而不是从网络设备重新获取新的定位辅助信息。这样的话,在定位会话阶段,可以缩短两次定位管理功能(Location Management Function,LMF)和终端设备之间的信令传输时延。
另外,网络设备也可以预配置多个有效区域的下行定位辅助信息,并将其发送给终端设备。当终 端设备在不同的区域移动时,终端设备可以直接使用所处区域关联的下行定位辅助信息直接进行定位测量。这样,也可以降低定位会话阶段中的信令传输时延。
在一些场景中,网络通过长期演进定位协议(Evolution Positioning Protocol,LPP)提供位置信息的消息(ProvideLocationInformation msg)为终端设备配置定位TRP及有关参考信号配置。
在预配置过程中,网络设备还需要将有效区域配置给终端设备。例如,预配置DL-PRS辅助信息,其中包括有效区域信息,例如通过区域ID(Area ID)表示。
在一些情况中,单个区域的组成可以是一个小区列表(cell list)。也就是说,当终端设备驻留在属于小区列表中的小区上时,终端设备可以应用预配置的DL-PRS辅助信息。
在一个区域内,终端设备通过对分布在不同位置的TRP执行下行参考信号测量,获得信号测量结果,如下行相对信号时间差(downlink relative signal time difference,DL RSTD)。最终,定位***依据测量结果对终端设备进行定位。
以DL PRS为例,DL PRS的配置信息由LMF通过LPP信令提供给终端设备。DL PRS的参数配置是采用了四层信令结构,从顶层到底层表示为:
定位频率层(Positioning Frequency Layer,PFL)最多4层;
TRP,最多64个每频率层;
DL PRS资源集(PRS resource set)最多两个每TRP每定位频率层;
DL PRS资源(PRS resource)最多64个每资源集每TRP每频率层。
针对每个PFL,终端设备所配置的是多个TRP发送在同样频率点的DL PRS信号。针对每个TRP可以配置一个或者两个DL PRS资源集,该一个或者两个DL PRS资源集配置了该TRP在某个频率点上发送的所有的DL PRS资源。而每个DL PRS资源集中可以配置多个DL PRS资源,每个DL PRS资源可以代表一个TRP的发送波束而不同的DL PRS资源可以代表这个TRP的不同发送波束。
终端设备通过对不同的TRP发送的参考信号执行测量,获得测量结果例如DL RSTD,该测量结果用于推导定位结果。
在一些场景中,最多可以为一个终端设备提供4个PFL的DL PRS配置。每一个PFL的参数结构中可以提供以下PRS信号的配置参数:
PRS信号的子载波间隔。
PRS信号的循环前缀(cyclic prefix,CP)长度。
PRS的频域资源带宽:这个参数取值是分配给PRS信号的物理资源块(Physical Resource Block,PRB)个数。可选地,PRS资源带宽最小值可以是24个PRB,颗粒度是4个PRB,而PRS资源带宽最大值可以是272个PRB。
PRS资源的频域起始频率位置:这个参数用于指示PRS信号在频域分配的起始PRB的索引号。PRB的索引号是相对于PRS的频域参考点A(PointA)所定义的。
PRS信号的频域参考点PointA。
PRS信号的梳齿尺寸(Comb-N)。
对于每个PFL,所配置的上述PRS参数可以应用在这个PFL所包含的所有PRS资源上。也就是说,在一个PFL中,来自多个不同TRP的所有PRS信号会使用同样的子载波间隔、CP长度,同样的梳齿尺寸,发送在同样的频率子带上,并且占用完全一样的带宽。这样的设计可以支持UE能够同时接收并测量发送同样频点上的来自多个不同的TRP的PRS信号。
TRP层的参数包括一个用于唯一识别该定位TRP的ID参数,该TRP的物理小区ID,该TRP的NR小区全局标识(NR Cell Global Identifier,NCGI)以及该TRP的绝对无线频道编号(Absolute Radio Frequency Channel Number,ARFCN)。每个TRP层可以最多配置2个DL PRS资源集。DL PRS资源集层参数可以配置了以下参数,其中,该参数可以应用到该DL PRS资源集所包含的所有的DL PRS资源。
DL PRS资源集合识别ID(nr-DL-PRS-ResourceSetID)。
DL PRS的传输周期和时隙偏移(dl-PRS-Periodicity-and-ResourceSetSlotOffset)。这个参数定义了包含在该DL PRS资源集中的所有DL PRS资源的时域发送行为。可配置的DL PRS的传输周期最小值是4毫秒,而最大值是10240毫秒。DL PRS的配置支持灵活的子载波间隔,包括15KHz,30KHz,60KHz和120KHz。在不同的子载波间隔情况下,可配置的DL PRS传输周期值范围是一样的。
DL PRS资源的重复因子(dl-PRS-ResourceRepetitionFactor):这个参数定义了一个PRS资源在每个PRS周期内的重复传输次数。同一个DL PRS资源的重复传输可以被UE用来聚合多次传输的DL PRS信号能量从而可以增加DL PRS的覆盖距离和增加定位精度。在FR2***中,DL PRS资源的重复传输可以被UE用来做接收波束扫描操作。UE可以用不同的接收波束来接收同一个DL PRS 资源的重复传输从而找到最佳的TRP发送波束和UE接收波束匹配。另外一方面,DL PRS资源的重复发送会增加PRS的开销。在一些场景中,DL PRS资源的重复因子取值为1,2,4,6,8,16和32。
DL PRS资源重复发送的时间间隔(dl-PRS-ResourceTimeGap):这个参数定义了同一个PRS资源的连续两次重复传输之间的时隙数。
DL PRS的静默(muting)配置:这个参数用来定义DL PRS信号在某些分配时频资源上不发送(称为muting)。muting是指DL PRS信号并不会在所有的分配的时频资源上发送,而是有意在某些指定的时频资源上不发送。这么做的目的一方面可以规避和其他信号比如同步信号块(Synchronization Signal Block,SSB)的冲突,另一方面可以规避不同TRP发送的信号之间的干扰,例如有意在某些时刻上关掉某个TRP的DL PRS发送从而使得UE能够收到来自较远的TRP的DL PRS信号。
DL PRS资源所占的OFDM符号数(dl-PRS-NumSymbols):这个参数定义了一个DL PRS资源在一个时隙内部所分配的OFDM符号数量。
如前所述,在一个DL PRS资源集这层配置里面所配置的所有参数会应用到这个资源集里面所包含的所有DL PRS资源。因此,在同一个DL PRS资源集里面的所有的DL PRS资源会以同样的周期发送,同样的重复传输次数,以及占用同样数量的OFDM符号。
每个DL PRS资源会配置如下的参数:
一个DL PRS资源识别ID(nr-DL-PRS-ResourceID);
DL PRS的序列ID(dl-PRS-SequenceID);
DL PRS的起始频域资源单元偏移(dl-PRS-CombSizeN-AndReOffset):这个参数定义了DL PRS资源在一个时隙内的第一个分配的OFDM符号上资源映射所用的频域资源单元偏移值。根据这个参数以及TS38.211里面规范的相对偏移值,UE就可以确定每个OFDM符号上资源映射所使用的频域资源单元偏移值;
DL PRS的资源时隙偏移(dl-PRS-ResourceSlotOffset):这个参数定义相对于DL PRS资源集的时隙偏移。这个参数可以确定每个DL PRS资源所处的时隙位置;
DL PRS的OFDM符号偏移(dl-PRS-ResourceSymbolOffset):这个参数定义了一个DL PRS资源在一个时隙内的时频资源分配位置,例如,该参数用于指示在一个时隙内的起始OFDM符号索引号;
DL PRS的QCL信息(dl-PRS-QCL-Info):这个参数提供了DL PRS信号的准共址信息(Quasi Co-Location,QCL)。
对于每个DL PRS资源,可以根据其对应的参数进行区分。
在一些场景中,例如覆盖范围外(out-of-coverage)场景下,终端设备无法接收到DL PRS,此情况下,如何进行准确的定位是一项亟需解决的问题。
图2是根据本申请实施例的无线通信的方法200的示意***互图,如图2所示,该无线通信的方法200可以包括至少部分内容:
S201,终端设备获取第一信息,第一信息包括第一配置信息,第一配置信息为至少一个锚点终端的侧行相关配置;

终端设备对目标网络设备发送的参考信号执行测量得到的测量结果。
应理解,本申请实施例可以应用于网络覆盖范围外(out-of-coverage)场景,或者,也可以应用于网络覆盖范围内场景,本申请对此不作限定。
在本申请实施例中,锚点终端可以是用于辅助终端设备定位的、在侧行链路或侧行通信频段上可以发送参考信号或者对接收的参考信号执行测量的终端。
在一些实施例中,锚点终端可以为路边单元(Road Side Unit,RSU)。
在一些实施例中,RSU的位置是固定的,相对于基于移动终端或网络设备进行定位,基于RSU对终端设备进行定位,有利于保证定位结果的精确度。
可选地,RSU是车载容迟网络中部署在路边进行辅助通信的设施,RSU与骨干网直接连接,并且可以与车载容迟网络中的车辆进行无线通信。
相对于车载容迟网络中的车辆,RSU具有更好的通信能力、覆盖范围和传输速度,而且可以同时与多个车辆进行通信。此外,RSU还有较大的存储空间,可以存储信息,提高通信概率。因此,通过在道路交通***中部署相关的RSU,一方面,能够有效地解决车载设备的互联网接入问题,另一方 面,也能极大地增加车载设备之间的通信机会,通过RSU缓存消息,实现车辆与车辆之间消息的高效传递。
在一些实施例中,第一信息是网络设备配置的。
例如,核心网设备可以通过接入网设备(例如基站)将第一信息发送给终端设备。
具体例如,核心网设备可以通过LPP信令(例如LPP ProvideAssistanceData)将第一信息发送给终端设备。

在一些实施例中,所述至少一个锚点终端的标识信息可以为能够唯一标识锚点终端的任意标识。
作为示例,锚点终端的标识信息可以为5G全局唯一标识临时终端标识(5G Globally Unique Temporary UE Identity,5G-GUTI)或5G缩短的临时移动用户标识码(5G Shorted Temporary Mobile Subscriber Identity,5G-S-TSMI)等。
在一些实施例中,锚点终端的侧行相关的参考信号配置可以用于配置参考信号的发送方式和/或发送资源等。

在一些实施例中,侧行相关的参考信号可以包括但不限于:

在一些实施例中,时间同步组的标识信息可以用于标识一个时间同步组,一个时间同步组可以包括一个或多个锚点终端,属于同一时间同步组的锚点设备之间建立时间同步。也就是说,属于同一时间同步组的锚点设备之间的时间同步是有保障的。
在一些实施例中,每个时间同步组可以对应一个第一指示信息,即第一指示信息可以是per时间同步组粒度的,每个时间同步组对应的第一指示信息用于指示该时间同步组中的锚点终端是否与网络设备时间同步。可选地,这里的网络设备可以指接入网设备,例如基站,比如终端设备当前驻留小区的基站。
例如,若一个时间同步组对应的第一指示信息指示与网络设备时间同步时,则该时间同步组的所有锚点终端均与网络设备时间同步。
在一些实施例中,每个锚点终端可以对应一个第二指示信息,即第二指示信息可以是per锚点终端粒度的,每个锚点终端对应的第二指示信息用于指示该锚点终端是否与网络设备时间同步。可选地,这里的网络设备可以指接入网设备,例如基站,比如终端设备当前驻留小区的基站。
例如,若一个锚点终端对应的第二指示信息指示与网络设备时间同步时,则该锚点终端与网络设备时间同步。
