Description

定位参考信号的传输方法及装置、电子设备及存储介质 技术领域
本公开实施例涉及无线通信领域但不限于无线通信领域，尤其涉及一种定位参考信号(Position Reference Signal，PRS)传输方法及装置、电子设备及存储介质。
背景技术
目前第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)开展了通信协议版本(Release，R)R17的轻型终端(Reduced capability NR devices，Redcap)项目研究，项目目标是再和R15或R16终端共存的情况下，减少UE的复杂度并节省成本。
PRS是上基站发送的下行信号。该PRS可用于UE的定位。但是Redcap UE的提出，会使得PRS的发送适配Redcap UE支持的带宽提出了挑战。
发明内容
本公开实施例提供一种定位参考信号传输方法及装置、电子设备及存储介质。
本公开实施例第一方面提供一种定位参考信号PRS的发送方法，其中，所述方法包括：
根据复合序列，发送复合PRS；

所述复合PRS占用的带宽大于所述截短PRS占用的带宽；且所述复合PRS和所述截短PRS，用于不同类型UE的定位测量。
本公开实施例第二方面提供一种定位参考信号PRS的接收方法，其中，所述方法包括：
根据UE类型，接收复合PRS或者截短PRS；其中，所述复合PRS为根据复合序列发送的；所述截短PRS为所述复合PRS的部分，且是根据所述复合序列的子序列发送的。
本公开实施例第三方面提供一种定位参考信号PRS的发送装置，其中，所述装置包括：
发送模块，被配置为根据复合序列，发送复合PRS；
所述复合序列包含多个子序列；且所述子序列对应的部分所述复合PRS为截短PRS；
所述复合PRS占用的带宽大于所述截短PRS占用的带宽；且所述复合PRS和所述截短PRS，用于不同类型UE的定位测量。
本公开实施例第四方面提供一种定位参考信号PRS的接收装置，其中，所述装置包括：
接收模块，被配置为接收复合PRS或者截短PRS；其中，所述复合PRS为根据复合序列发送的；所述截短PRS为所述复合PRS的部分，且是根据所述复合序列的子序列发送的；

本公开实施例第五方面提供一种通信设备，包括处理器、收发器、存储器及存储在存储器上并能够有所述处理器运行的可执行程序，其中，所述处理器运行所述可执行程序时执行如前述第一方面和/或第二方案提供的方法。
本公开实施例第六方面提供一种计算机存储介质，所述计算机存储介质存储有可执行程序；所述可执行程序被处理器执行后，能够执行如前述 第一方面和/或第二方案提供的方法。
本公开实施例中提供的技术方案，PRS是根据复合序列发送的，PRS为将PRS序列调制到载波上形成的。而复合序列是可以拆分成多个子序列的，如此，整个完整的复合序列对应的PRS为复合PRS，而子序列对应的PRS为截断PRS。如此，基站可以不区分UE类型的，根据复合序列下发PRS，从而简化PRS的发送。于此同时，由于复合PRS和截短PRS都可以用于UE定位测量，因此直接根据复合序列下发的PRS，可以适用于不同类型UE的定位测量，从而使得不同类型UE都能够成功根据接收的PRS完成定位测量。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端110以及若干个基站120。
其中，终端110可以是指向用户提供语音和/或数据连通性的设备。终端110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端110可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代 理(user agent)、用户设备(user device)、或用户终端(user equipment，终端)。或者，终端110也可以是无人飞行器的设备。或者，终端110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线终端。或者，终端110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和终端110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信系统中的核心网设备，比如，该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备130的实现形态，本公开实施例不做限定。
如图2所示，本实施例提供一种PRS的发送方法，其中，所述方法包括：
S110：根据复合序列，发送复合PRS；
所述复合序列包含多个子序列；且所述子序列对应的部分所述复合PRS为截短PRS；
所述复合PRS占用的带宽大于所述截短PRS占用的带宽；且所述复合PRS和所述截短PRS，用于不同类型UE的定位测量。
第一类UE。
本公开实施例提供的PRS的发送方法，可应用于基站中。基站通过PRS的发送，可以辅助UE进行自身的定位测量。例如，UE可以根据接收到的PRS的接收功率等，确定出自身与基站之间的距离。再例如，可 以根据发送PRS的波束的波束方向，还可以确定出UE与基站之间的角度，从而基站通过PRS的发送，可以辅助UE进行自身的定位测量。
在一些实施例中，按照支持的带宽划分UE，至少可分为：第一类UE和第二类UE。
所述第一类UE可为：轻能力新无线设备(Reduced capability NR devices)该轻能力新无线设备又可以简称轻型UE。所述第二类UE可包括：eMBB UE。
在应用过程中，第一类UE和第二类UE的类型可以通过UE的能力(例如，支持的带宽)来区分。此处的所述第一类UE支持的最大带宽小于某些第二类UE支持的最大带宽。
所述复合序列为形成PRS一种序列。复合序列可以拆分成多个子序列。复合序列自身和拆分成的子序列自身都满足通信中对序列的要求。
例如，所述复合序列本身和被拆分后形成截短PRS的子序列都不能是全“1”序列或者全“0”等。
再例如，不同复合序列之间的差异度要足够大，使得UE能够区分当前接收的是哪个PRS序列对应的PRS，则一个复合序列拆分出的多个子序列也是满足差异度足够大，例如，差异度大于阈值，例如，预定个数的比特值不同等，从而使得UE能够正确接收到需要接收的截短PRS。
在一些特定情况下，一个复合序列拆分出的多个子序列可正交。子序列正交是满足差异度足够大的一种体现。
在一个实施例中，若一个复合序列可以拆分成两个子序列，则一个复合序列的长度不小于2个子序列之和。
在另一个实施例中，为了简化基站的PRS发送，第一个子序列的起始位置为复合序列的起始位置开始，和/或，最后一个子序列的终止位置可为复合序列的终止位置结束。
在一些实施例中，子序列中可为复合序列中连续分布的比特形成的；在另一个实施例中，子序列中可为复合序列中离散分布的比特形成的。
例如，复合序列包含2m个比特时，则一个子序列可为2m个比特中的第偶数个比特组合而成，或者，第偶数个比特组合而成。
总之，不同类型的UE可以根据相同的复合序列对应的复合PRS或者截短PRS进行定位，则基站可以进维护一个复合序列的序列集即可，
简化了基站中存储的序列集。
基站形成的一个小区内可包含第一类UE，也可以包含预定类型外的UE。这两种类型的UE支持的带宽是不同。基站在进行PRS发送时，若需要不区分UE类型的进行PRS发送，减少基站在区分UE类型的PRS发送导致的PRS发送复杂度时，还需要确保第一类UE能够接收到该UE，并能够根据该接收的PRS进行定位测量。由于复合PRS和截短PRS都可以用于UE定位测量，因此直接根据复合序列下发的PRS，可以适用于不同类型UE的定位测量，从而使得不同类型UE都能够成功根据接收的PRS完成定位测量。
在一些情况下，基站内多个UE同时需要进行定位时，基站可以根据复合序列广播或组播复合PRS，而不同类型的UE，可以根据基站给自己的PRS配置或者根据自己的类型，选择接收复合PRS或截短PRS，从而基站不仅可以通过PRS的一次性发送，可以辅助多个UE的定位，而且基站还可以通过PRS的一次发送，辅助不同类型UE的定位。在一些实施例中，所述复合序列包括：由所述子序列组合而成；
或者，
所述子序列为：所述复合序列截短形成的。
在一种情况下，基站可以根据序列生成算法，生成所述复合序列，然后将所述复合序列拆分成一个或多个子序列。
在另一种情况下，基站可以根据序列生成算法，生成子序列；然后将多个子序列按照一定的组合策略，组合形成所述复合序列。
在一个实施例中，至少两种不同类型UE包含：第一类UE和第二类UE；所述第一类UE支持的带宽小于所述第二类UE支持的带宽；
所述截短PRS发送占用的带宽，小于或等于所述第一类UE支持的带宽。
若不同类型的UE按照支持的带宽分，至少可以分为两类，且第一类UE支持的带宽较小，为了方便第一类UE的定位，所述截短PRS用于第一类UE的定位，故截短PRS发送占用的带宽小于或等于第一类UE支持的带宽。
例如，第一类UE支持的带宽不大于40M，则所述截短PRS发送占用的带宽小于或等于40M。若所述第一类UE支持的带宽不大于20M，则截短PRS发送占用的带宽小于或等于20M。若第一类UE支持的最大带宽为10M，则节点PRS发送占用的带宽小于或等于10M。
如此，确保截短PRS能够被第一类UE的成功接收。
而复合PRS发送占用的带宽小于或等于第二类UE支持的带宽，从而，能够确保第二类UE可以成功接收到复合PRS，从而实现第二类UE的成功定位。
为了确保PRS的接收功率，确保UE的定位成功进行，在本公开实施例中，则PRS会具有重复配置，该重复配置可用于重复发送PRS。
所述S110可包括：
根据所述复合序列及重复配置，重复发送所述复合PRS；
其中，所述重复配置至少包括：
重复次数，指示所述复合PRS的重复次数；
和/或，
重复资源配置，指示重复所述复合PRS的资源。
若重复次数为M，则PRS会发送M次。
重复资源配置，指示的重复发送复合PRS的时域资源、频域资源、和/或波束资源等。
值得注意的是：为了简化支持带宽小的UE对截短PRS的接收，通常一个子序列对应的截短PRS可设置在一个频段上重复发送，如此，接收截短PRS的UE可以不切换接收频带的情况下，接收所述截短PRS。
当然为了具有频率增益，若具有多次重复发送，可以在不同的频带上发送PRS的不同次。此时，为了简化UE切换频带的接收，不同频带在频域可是连续的。
如图3所示，本实施例提供一种PRS接收方法，其中，包括：
S210：接收复合PRS或者截短PRS；其中，所述复合PRS为根据复合序列发送的；所述截短PRS为所述复合PRS的部分，且是根据所述复合序列的子序列发送的；所述复合PRS占用的带宽大于所述截短PRS占用的带宽；且所述复合PRS和所述截短PRS，用于不同类型UE的定位测量。
在本公开实施例中提供的PRS接收方法，为应用于UE中的方法，该UE可为各种类型的UE，例如，支持大带宽的UE和/或支持小带宽的UE。例如，前述的Redcap UE和/或eMBB UE等。
UE可以根据自己的类型，选择接收复合PRS或者截短PRS。例如，当前UE为支持小带宽的UE，可以选择接收截短PRS，如此，可以根据截短PRS的资源配置进行截短PRS的。若当前UE为支持带宽的UE，可以选择接收复合PRS，例如，可以根据复合PRS的资源配置进行复合PRS的接收。
总之，基站可以根据复合序列下发复合PRS，而不同类型的UE，可 以根据基站的一次复合PRS的下发，进行复合PRS接收或者截短PRS，然后根据接收的PRS进行定位，从而确定出自身与基站之间的相对位置，从而完成自身的定位。
在一些实施例中，所述S210可包括：若所述UE为第一类UE，接收所述截短PRS；若所述UE为第二类UE，接收所述复合PRS；其中，所述第二类UE支持的带宽大于所述第一类UE支持的带宽。
不同类型的UE至少可以分为两类，一类是第一类UE，另一类是第二类UE，第一类UE支持大带宽小于第二类UE，第一类UE支持的带宽小于第二类UE支持的带宽，因此，第一类UE可以接收截短PRS，而支持较大带宽的第二类UE接收复合PRS。
在基站需要辅助多个UE同时进行定位时，可以通过一次复合PRS的发送，辅助多个UE完成定位。

本公开实施例还提供一种PRS传输方法，包括：
根据UE类型，发送PRS；不同类型的UE的PRS的发送方式不同。
例如，针对前述第一类UE，则在第一带宽上重复发送PRS；针对比第一类UE支持带宽大的第二类UE，则在第二带宽上发送PRS。第二带宽大于所述第一带宽。
在一些实施例中，所述第一带宽小于或等于所述第一类UE支持的带宽。
所述第二带宽大于所述第一类UE支持的带宽，且小于或等于第二类UE支持的带宽。
在一些实施例中，所述第二带宽为2倍以上的所述第一带宽。

在另一些实施例中，所述第一带宽和第一时域资源数量对应的总通信资源数量，与第二带宽和第二时域资源数量对应的总通信资源数量可相同。
在一些实施例中，所述第二带宽为2倍所述第一带宽；所述第二时域资源数量为1/2所述第一时域资源数量。
当然在另一些实施例中，所述第一带宽也可以为3/4的所述第二带宽。

例如，时域单位为符号，第二时域资源数量为2，则第一时域资源数量为4，则第二时域资源数量对应的2个符号之间至少间隔2个符号。如此，针对不同类型的UE的PRS传输，可以使用同一个资源池进行传输，如此，不同类型的UE可以共用同一片传输PRS的资源池。
在一些情况下，所述第一类UE包括但不限于：增强移动带宽(enhance Mobile Broadband，eMBB)UE。
例如，针对e,MBB UE的PRS传输，则在1个资源单元(Resource Element，RE)的2个符号上传输，而针对redcap UE的PRS传输，则半个RE上的4个符号上传输。
此处的PRS传输包括：基站的PRS发送和/或UE的PRS接收。
在本公开实施例中，基站和UE，针对不同类型的UE以不用的方式传输PRS，实现了不同类型UE的PRS解耦，从而能够确保每一种UE都能够接收到适合自身定位测量的PRS，实现定位测量。
以下结合上述任意实施例提供几个具体示例：
示例1：
在应用场景中有传感器的设备，视频监控和可穿戴类设备，其带宽要求通常比较低，20-40M，甚至10M的可能。以支持20M带宽的Redcap UE为例。
PRS是3GPP NR空口中基站发送的下行信号，用于定位。众所周知，定位的带宽和精度成正比，因此PRS的带宽从最小24个物理资源块 (Physical Resource Block，PRB)到最大272PRB，通常基站会根据定位精度要求，系统资源的情况，选择合适的带宽，例如，96个PRB，SCS＝30KHz，约35M，并最小配置两个连续的时域符号。
如果要提高精度，则会配置更大的带宽或者更多的时域符号，或者一起(频域带宽的扩展精度提升要高于时域重复)。但是对于Redcap UE受限于UE带宽，同一时间只能配置UE最大支持带宽的PRS的带宽，比如20M，那么精度就会下降很多，为了保证Redcap UE在某些需求下能达到更高的定位精度，需要在PRS的配置上兼容Redcap UE，并尽可能节省资源。
正常UE(即指支持的带宽大于所述redcap UE)两个符号，间隔RE配置即可。因为超过了Redcap UE的带宽，给Redcap UE配置4个符号的小带宽重复，然而这样的定位精度和大带宽比不够，这里给出了一个2倍的例子，也可能是3/4倍的带宽。
示例2：
对于一个带宽为n的PRS序列，基站配置给Redcap UE采用跨符号跳频的方式，即将序列的第一部分配置在第一个符号，第2部分配置到第2个符号的相邻的不同带宽，第3个符号以此类推(如果带宽超过2倍)。
在配置上将PRS的PRS序列分为n个部分；比如图中是2个部分，第一个部分在第一个符号第一频域发送；第二部分在第二符号第二频域发送，以此类推第三，第四符号。
还有一种方案是第一个部分在第一个符号第一频域发送；第二部分在第三符号第二频域发送；第二部分在第二个符号的第一频域发送，如图中的第二个部分。
基站侧保证n个部分中第一部分……第n部分在频域上连续，并保证相邻两个部分中前一个部分的最后一个调制信号的调制相位，和后一个部分的首个调制信号的调制纤维，在调制相位的相位序列上连续，以上两种 配置隐含保证相位连续。
基站也可以不配置相邻两个部分的调制相位在调制相位对应的相位序列上连续，通过多次时域重复的方法；基站也可以不配置相位连续，通过跳频重复的方法配置。
UE侧：UE根据基站的PRS配置进行PRS接收，并进行不同部分的合并解调
