多端口定位参考信号测量方法、装置及通信设备
相关申请的交叉引用
本申请主张在2021年12月30日在中国提交的中国专利申请No.202111658923.2的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于无线通信技术领域，具体涉及一种多端口定位参考信号测量方法、装置及通信设备。
背景技术
目前的通信协议中，仅支持单端口的定位参考信号，这使得定位精度不够准确。人工智能(Artificial Intelligence，AI)定位中，需要测量多个端口的定位参考信号，多个端口的定位参考信号的测量结果有利于提升定位精度。旁链路(Sidelink)中，终端可能存在分布式天线，分布式天线可能对应不同端口或端口组。离开角(Angle Of Departure，AOD)定位场景中，多端口的定位参考信号能够通过相位计算的方式，精确地得到AOD。因此，后续的基于定位参考信号的定位方案中，对多个端口的定位参考信号设计有需求。
基于新空口的车用无线通信技术(New Radio-vehicle to everything，NR-V2X)定义了两种资源分配模式(mode)，一种是mode1，为基站调度资源；另一种是mode2，终端(User Equipment，UE)自己决定进行传输时使用的资源，此时资源信息可能来自基站的广播消息或者预配置的信息。UE如果工作在基站范围内并且与基站有无线资源控制(Radio Resource Control，RRC)连接，可以是mode1和/或mode2，UE如果工作在基站范围内但与基站没有RRC连接，只能工作在mode2。如果UE在基站范围外，则只能工作在mode2，根据预配置的信息来进行车用无线通信技术(Vehicle to everything，V2X)传输。在mode1情况下，现有技术不支持sidelink定位，且也没有sidelink定位时信号调度的相关方案。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的多端口定位参考信号测量方法、装置及通信设备进行详细地说明。
下面首先对本申请相关的通信名词进行简单介绍。
(1)新无线(New Radio，NR)定位标准化进展
NR重新设计了基于NR系统的下行定位参考信号NR DL PRS，包括以下内容：
1)目前协议中，定位参考信号仅支持单端口。
2)定位参考信号(Positioning Reference Signal，PRS)可以来自多个发送接收点(Transmission Reception Point，TRP)，多个TRP可以来自服务小区或非服务小区。UE对多个TRP的PRS进行测量，随后进行定位测量上报或进行定位计算。
3)PRS支持在FR1最大100M以及FR2最大400M传输。NR PRS带宽配置与带宽部分(Bandwidth Part，BWP)配置无关，当PRS带宽大于BWP带宽时，支持用户设备(User Equipment，UE)使用测量间隔(Measurement Gap)对PRS进行测量。
4)PRS支持波束赋形，因此引入了PRS资源(resource)的概念。PRS resource ID可以对应1个TRP中的1个波束。1个或多个PRS resource可以组成1个PRS资源集(resource set)，或者说1个PRS resource set内可以包含1个或多个PRS resource。一个TRP可以包含1个或多个PRS resource。同时，为了增加UE的可听性，支持PRS波束扫描以及PRS波束重复。另外，支持PRS参考邻小区参考信号(Reference Signals，RS)作为空间准共址(Quasi Co-Location，QCL)参考信号。
5)PRS支持交错的图样(pattern)并且支持灵活的pattern配置。PRS resource的梳状(comb)结构可以支持{2,4,6,12}；符号(symbol)数可以支持{2,4,6,12}。目前支持的symbol数与comb size的组合如表1所示：
表1
  2 symbols 4 symbols 6 symbols 12 symbols
Comb-2 {0,1} {0,1,0,1} {0,1,0,1,0,1} {0,1,0,1,0,1,0,1,0,1,0,1}
Comb-4 NA {0,2,1,3} NA {0,2,1,3,0,2,1,3,0,2,1,3}}
Comb-6 NA NA {0,3,1,4,2,5} {0,3,1,4,2,5,0,3,1,4,2,5}
Comb-12 NA NA NA {0,6,3,9,1,7,4,10,2,8,5,11}
不同comb结构下典型的PRS pattern如图2所示。
(2)PRS端口
长期演进(Long Term Evolution，LTE)只支持单端口的PRS发送，NR Rel-16定位讨论了是否支持单端口和两端口PRS的发送。但由于两端口的PRS将引入更多的资源开销，且并没有足够的论证，最后Rel-16只通过了支持单端口的PRS。
(3)PRS序列
UE应假设参考信号序列r(m)定义为：
Figure PCTCN2022143574-appb-000001
其中，伪随机序列c(i)在第5.2.1节中定义。伪随机序列发生器应初始化为：
Figure PCTCN2022143574-appb-000002
其中，
Figure PCTCN2022143574-appb-000003
为时隙号，下行链路PRS序列ID
Figure PCTCN2022143574-appb-000004
由高层参数dl-PRS-SequenceID给出，l是序列映射到的时隙内的OFDM符号。
PRS序列为Gold序列并进行正交相移键控(Quadrature Phase Shift Keying，QPSK)调制获得。其中，Gold序列的初始化函数为c init，它的设计要求区分每个TRP的PRS，保持各个TRP的DL PRS之间的干扰随机化和良好的序列互相关特性。
(4)PRS映射
对于配置的每个下行链路PRS资源，UE应假设序列r(m)用因子β_"PRS"缩放，并根据以下等式映射到资源单元(k,l) p,μ:
Figure PCTCN2022143574-appb-000005
当满足以下条件时：
资源单元(k,l) p,μ位于为其配置UE的下行链路PRS资源所占用的资源块内；
符号l不被服务小区用于从同一服务小区发送的下行链路PRS的任何同步信号/物理广播信道块((Synchronization Signal，SS)/(Physical Broadcast Channel，PBCH))块或非服务小区的任何SS/PBCH块使用，其时频位置由更高层提供给UE用于从同一非服务小区发送的下行链路PRS；
时隙号满足第7.4条中的条件7.4.1.7.4.
(5)多端口信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)设计
多个端口的CSI-RS可以分为不同的码分复用(Code Domain Multiplexing，CDM)group，其中不同的CDM group的CSI-RS时频位置可以不同；一个CDM group占用时域和/或频域连续的资源单元(Resource Element，RE)位置，且一个CDM group中不同的端口通过频域正交码(FD-OCC)和/或时域正交码(TD-OCC)区分，占用相同的时域和频域位置，请参考表2：
表2
Figure PCTCN2022143574-appb-000006
(6)CSI-RS序列设计
UE应假设参考信号序列 r(m)定义为:
Figure PCTCN2022143574-appb-000007
其中，伪随机序列c(i)在第5.2.1节中定义。伪随机序列发生器应初始化为：
Figure PCTCN2022143574-appb-000008
在每个OFDM符号的开头，其中
Figure PCTCN2022143574-appb-000009
是无线电帧内的时隙编号，是时隙内的OFDM符号编号，等于高层参数scramblingID或sequenceGenerationConfig。
(7)CSI-RS映射
对于每个配置的CSI-RS，UE应假设序列r(m)被映射到资源元素(k,l) p,μ，根据：
Figure PCTCN2022143574-appb-000010
当满足以下条件时：
资源单元(k,l) p,μ在UE配置的CSI-RS资源占用的资源块内k＝0的参考点是公共资源块0中的子载波0。ρ的值由CSI-RS-ResourceMapping IE或CSI-RS-CellMobility IE中的高层参数给出，端口数X由高层参数nrofPorts给出。
