定位参考信号处理方法、终端及网络侧设备
相关申请的交叉引用
本申请要求于2021年07月29日提交的申请号为2021108655656，发明名称为“定位参考信号处理方法、终端及网络侧设备”的中国专利申请的优先权，其通过引用方式全部并入本申请。
技术领域
本申请属于通信技术领域，具体涉及一种定位参考信号处理方法、终端及网络侧设备。
背景技术
在未来通信***中，非授权频段(unlicensed band)可以作为授权频段(licensed band)的补充帮助运营商对服务进行扩容。为了与新空口(New Radio,NR)部署保持一致并尽可能的最大化基于NR的非授权接入，非授权频段可以工作在5GHz，37GHz和60GHz频段。非授权频段的大带宽(80或者100MHz)能够减小基站和用户设备(User Equipment，UE)的实施复杂度。由于非授权频段由多种无线接入技术(Radio Access Technology，RATs)共用，例如无线保真(Wireless Fidelity，WiFi)，雷达，长期演进辅助授权接入(Long Term Evolution Licensed Assisted Access，LTE-LAA)等，因此在某些国家或者区域，非授权频段在使用时必须符合规则(regulation)以保证所有设备可以公平的使用该资源，例如先听后说(listen before talk，LBT)，最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等规则。当传输节点需要发送信息时，需要先做LBT时，对周围的节点进行功率检测 (energy detection，ED)，当检测到的功率低于一个门限时，认为信道为空(idle)，传输节点可以进行发送。反之，则认为信道为忙，传输节点不能进行发送。传输节点可以是基站，UE，WiFi接入点(Access Point，AP)等等。传输节点开始传输后，占用的信道时间COT不能超过MCOT。
常用的LBT的类型(category)可以分为category 1，category 2和category4。Category1 LBT是传输节点不做LBT，即no LBT或者立即传输(immediate transmission)。Category 2 LBT是一次(one-shot)LBT，即传输节点在传输前做一次LBT，信道为空则进行传输，信道3为忙则不传输。Category 4 LBT是基于回退(back-off)的信道侦听机制，当传输节点侦听到信道为忙时，进行回退，继续做侦听，直到侦听到信道为空。对于基站，category2 LBT应用于发现参考信号(Discovery Reference Signal，DRS)without物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、category 4 LBT应用于PDSCH/下行控制信息(Downlink Control Information,DCI)/扩展DCI(extended DCI,eDCI)。对于UE，category4 LBT对应于type1上行信道接入步骤(UL channel access procedure)，category2 LBT对应于type2 UL channel access procedure。此外，在非授权新无线(New Radio Unlicense，NR-U)***中，新增加了一种category2 LBT，对应于16us的间隔gap。
利用非授权频段的载波传输定位参考信号能够进一步提高定位的精度。非授权频段定位参考信号(Positioning Reference Signal，PRS)的传输主要会受到LBT的影响，比如，基站只有在LBT成功之后，才能发送PRS。因此，需要考虑如何提高非授权频段定位参考信号的传输效率。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long  Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)***，还可用于其他无线通信***，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他***。本申请实施例中的术语“***”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的***和无线电技术，也可用于其他***和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)***，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR***应用以外的应用，如第6代(6 th Generation，6G)通信***。
图1示出本申请实施例可应用的一种无线通信***的结构图。无线通信***包括终端11、接入网设备12和核心网设备13。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装、游戏机等。需要说明的是，在本申请实施例并不限定终端11的具体类型。接入网设备12也可以称为无线接入网设备或无线接入网(Radio Access Network,RAN)，接入网设备12可以为基站，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节 点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR***中的基站为例，但是并不限定基站的具体类型。核心网设备13也可以称为核心网(Core Network,CN)或5G核心(5G core，5GC)网，核心网设备13可以包含但不限于如下至少一项：核心网节点、核心网功能、移动管理实体(Mobility Management Entity，MME)、接入移动管理功能(Access Management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户平面功能(User Plane Function，UPF)、策略控制功能(Policy Control Function、PCF)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)、边缘应用服务发现功能(Edge Application Server Discovery Function，EASDF)、应用功能(Application Function，AF)、位置服务器等。需要说明的是，在本申请实施例中仅以5G***中的核心网设备为例，但是并不限定此为限。
非授权频段定位参考信号(Positioning Reference Signal，PRS)的传输主要会受到LBT的影响，比如，gNB只有在LBT成功之后，才能发送PRS。因此，为了提高定位时PRS发送成功的几率，可能需要引入PRS候选位置的概念。即，在多个候选位置发送PRS，那么即使某些候选位置由于LBT未成功不能发送PRS，剩下的候选位置也会有发送PRS的机会。
另外，考虑到sidelink定位中，PRS的传输在非授权频段，而PRS的控制可在授权频段。因此，还可以考虑在授权频段指示非授权频段的PRS传输，进一步提升***的灵活性和完整性。
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定位参考信号处理方法进行详细地说明。
图2为本申请实施例提供的定位参考信号处理方法的流程示意图之一，如图2所示，该方法包括以下步骤：
步骤200、第一终端获取定位参考信号PRS的候选位置；
步骤201、根据所述候选位置，执行第一操作；
其中，所述第一操作包括以下至少一项：
检测PRS是否存在；
对PRS进行测量和/或处理。
其中，定位参考信号PRS不限于Uu的PRS，sidelink的PRS。
本申请方案中，定位参考信号PRS为用于定位的参考信号，这里PRS还可以换成其他用于定位的参考信号，包含但不限于信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)，同步信号块(Synchronization Signal and PBCH Block,SSB)，追踪参考信号(Tracking Reference Signal，TRS),解调参考信号(Demodulation reference signal，DMRS)至少之一。值得指出的是，本申请实施例仅以PRS为例对定位参考信号的处理方法做示例性说明，其他用于定位的参考信号的实现方式亦可参照相同方式实现，故不再一一举例说明。
NR重新设计了基于NR***的下行定位参考信号NR DL PRS。
PRS支持在频率范围1(Frequency range 1，FR1)最大100M以及频率范围2(Frequency range 2，FR2)最大400M传输。NR PRS带宽配置与部分带宽(Bandwidth Part，BWP)配置无关，当PRS带宽大于BWP带宽时，支持UE使用测量间隙Measurement Gap对PRS进行测量。
PRS支持波束赋形，因此引入了PRS 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 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 Signal，RS)作为空间准共站址(Quasi-collocation，QCL)参考信号。
PRS支持交错的图样pattern并且支持灵活的pattern配置。PRS resource的comb结构可以支持{2,4,6,12}；symbol数至少可以支持{2,4,6,12}。目前支持的symbol数与comb size的组合如表1所示。
表1 symbol数与comb size
  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}
为了减小小区间的干扰，扩展了LTE中muting相关的技术。
候选位置也可以称为候选窗，包含时域和/或频域候选位置。
可以理解的是，第一终端根据PRS的候选位置，检测PRS是否存在，进一步对PRS进行测量和/或处理，以提高非授权频段中定位参考信号传输成功的机会。
其中，所述候选位置表示所述PRS的传输机会。候选位置表示PRS的可能传输位置。
每个候选位置代表一次(时间连续的)定位参考信号传输机会，可能存在定位参考信号的传输。
可选地，所述候选位置信息由网络设备配置，网络设备预配置，第二终端配置，或协议预定义。
例如，通过LTE定位协议(LTE Positioning Protocol，LPP)配置，或者sidelink中的资源池配置获得。所述网络设备可以是第一网络设备(位置服务器)，或者第二网络设备(基站)。
可选地，第二终端是Sidelink中的另一个UE，或者RSU，或者sidelink中的控制节点。
可选地，检测PRS是否存在是指在候选位置对PRS进行检测。
可选地，在检测到PRS之后，第一终端对PRS进行测量和/或处理。其中，对PRS进行处理是先将PRS缓存下来，再进行时域或频域计算。或者，同时缓存和处理，或者直接处理。
可选地，所述候选位置的特征包括以下至少一项：
候选位置个数，其中，候选位置个数可以是一个或多个；
候选位置为周期性，半持续性或非周期性；
候选位置的配置单位，包括以定位频率层，发送接收点，定位参考信号资源集，定位参考信号资源，终端或终端组为一个单位进行配置；
候选位置标识；
候选位置时间戳；
最大预留reserve数。
可选地，若候选位置为周期性或半持续，候选位置周期与PRS周期相同；一个周期内有1个或多个候选位置。
可选地，候选位置以定位频率层为单位(per positioning frequency layer)进行配置，或者以发送接收点为单位(per TRP)进行配置，或者以定位参考信号资源集为单位(per PRS resource set)进行配置，或者以定位参考信号资源为单位(per PRS resource)进行配置，或者以终端或终端组为单位(per UE或者UE group)进行配置。那么，候选位置关联对应的标识，如frequency layer ID,TRP ID,PRS resource set ID,PRS resource ID,UE ID或UE group ID至少之一，可选的，这些标识可以包含在候选位置的配置中。
可选地，比如一个周期内的候选位置标识从0到N-1，其中，N为一个周期内的候选位置个数，候选位置标识可包含在候选位置配置中。
可选地，候选位置时间戳对应的时间为候选位置最早，最晚，正中间或任意的子帧subframe或时隙slot或符号symbol对应的索引index。比如：UE指示候选位置关联的信息时，会携带候选位置的时间戳。所述时间戳根据上述方式确定。
