背景技术
第五代蜂窝移动通信(5 thGeneration，5G)R16引入了多种定位技术，可以实现对用户设备(User Equipment，UE)的定位。对于其中的一些定位技术，均需要定位管理功能(Location Management Function，LMF)向UE提供定位辅助信息。此处的LMF为一种通信实体。
因此LMF将定位辅助信息通过长期演进定位协议(Long term evolution Position Protocol，LPP)消息发送给UE。具体的，UE的服务基站以透传的方式通过无线资源控制(Radio Resource Control，RRC)消息将定位辅助信息发送给UE。另外，LMF可以将定位辅助信息通过新空口定位协议A(New Radio Positioning Protocol a，NRPPa)消息发送给基站，然后基站通过***消息以广播的方式发送给UE。

请参考图1，其示出了本公开实施例提供的一种无线通信***的结构示 意图。如图1所示，无线通信***是基于蜂窝移动通信技术的通信***，该无线通信***可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11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11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，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11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通信设备。或者，终端11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12可以是无线通信***中的网络侧设备。其中，该无线通信***可以是***移动通信技术(the 4th generation mobile communication，4G)***，又称长期演进(Long Term Evolution，LTE)***；或者，该无线通信***也可以是5G***，又称新空口(new radio，NR)***或5G NR***。或者，该无线通信***也可以是5G***的再下一代***。其中，5G***中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC***。
其中，基站12可以是4G***中采用的演进型基站(eNB)。或者，基站12也可以是5G***中采用集中分布式架构的基站(gNB)。当基站12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12的具体实现方式不加以限定。
基站12和终端11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***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11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***还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信***中的核心网设备，比如，该网络管理设备13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13的实现形态，本公开实施例不做限定。
图2A所示为：LMF通过NRPPa协议所规定的NRPPa消息，与基站 (包括但不限于gNB)交互PRS定位的各种信息，例如，包括但不限于PRS配置。例如，在图2A中，LMF向gNB请求DL-TDOA请求，该请求也包含了LMF推荐的PRS配置，gNB收到该请求后向LMF发送DL-TDOA响应，该DL-TDOA响应也包含了基站的PRS配置信息，并且同时基站根据PRS配置信息发送PRS。
图2B所示为：LMF通过LPP协议所规定的LPP消息，通过基站的透传直接与UE交互PRS定位的各种信息，例如，包括但不限于PRS配置。
5G R16引入了多种定位技术，可以实现对UE的定位。对于其中的一些定位技术，均需要网络向UE提供定位辅助信息，例如图2C所示，LMF通过LPP消息向UE提供定位辅助信息。另外，LMF也可以通过NRPPa消息将定位辅助信息发功给基站，然后基站通过***消息发送给UE，如图2C所示，可包括：
1.LMF向基站等无线网接入节点发送NRPPa定位辅助消息(NRPPa Assitance Information Control)，例如，图2C所示的5G基站等下一代无线接入网(Next Generation-Radio Access Network，NG-RAN)节点(Node)无线网接入节点；
2.NG-RAN节点向UE发送RRC***信息(RRC System Information)；
3.LMF向接入管理功能(Access Management Function，AMF)发送广播密钥通知((Nlmf_Broadcast_CipheringKeyData Notify(Ciphering Keys)))。所述Ciphering Keys为用于基站广播的信息加密的密钥。
4.NG-RAN节点向LMF发送NRPPa消息反馈(Assistance Information Feedback)，以反馈是否正确接收了LMF发送的信息。但是该步骤是一个可选步骤。
5.LMF向基站等无线网接入节点发送NRPPa定位辅助消息(NRPPa Assitance Information Control)。
6.发送RRC***信息(RRC System Information)。
7.LMF向基站等无线网接入节点发送NRPPa定位辅助消息(NRPPa Assitance Information Control)。
在相关技术中，R16的PRS配置均为静态配置，但是考虑到UE的定位精度需求，以及***开销等问题，动态PRS配置能够在满足高精度定位需求的同时降低***开销，因此需要实现动态的定位广播辅助信息。
如图3A所示，本申请实施例提供一种定位参考信号PRS配置处理方法，其中，应用于定位管理功能LMF，包括：
S110：下发携带有多套PRS配置的第一配置信息，其中，多套PRS配置对应于一个基站或一个TRP；PRS配置用于用户设备UE的定位测量。
如此，一个基站可由多套备选的TPS配置；或者，一个TRP具有多套备选的TPS配置。
该第一配置信息可为LMF下发基站或TPR的，也可是通过基站或TRP透传给UE的。若下发给基站或TPR的，则该第一配置信息可通过NRPPa消息来携带。若LMF直接下发给UE的，则通过LPP消息来携带该第一配置信息。
PRS配置可包括以下至少之一：
PRS资源配置，用于指示定位参考信号的资源位置。
PRS的测量方式配置，用于对PRS的测量方式，包括但不限于：下行链路达到时间差(Downlink-Time Difference of Arrival，DL-TDOA)方式、上行链路达到时间差(UPlink-Time Difference of Arrival，UL-TDOA)方式、下行链路达到角度(Downlink-Arrival of Angle，DL-AOA)方式及增强的小区标识定位方式(Enhanced Cell-IDentifity positioning method，E-CID)的至少其中之一；
测量参数配置，包括但不限于：定位参考信号的参考信号接收功率(Position Reference Signals-Reference Signal Receiving Power，PRS-RSRP)、定位参考信号的参考信号时间差(Position Reference Signals-Reference Signal Time Difference，PRS-RSTD)；
定位服务质量要求配置，包括但不限于：定位精度和/或定位延时。
同时下发多套PRS配置，则可以在进行定位时，选择符合当前定位需求的PRS配置，确保满足定位需求的同时尽可能减少信令开销。
在一些实施例中，不同套PRS配置所满足的定位精度不同；和/或，不同套PRS配置所需的定位开销不同。
由于多套PRS配置，则基站和UE在进行定位测量时，可以选择适用于当前定位需求的PRS配置。
以定位距离来确定定位精度，则定位精度包括：有的定位精度要求定位到10米级别、有的定位精度要求定位到米的级别，有的定位精度要求定位到分米或厘米级别。
以对PRS的信号质量来确定定位精度，则定位精度可包括：PRS的接收功率或者接收质量的精确度需要大大分贝级别或者0.1分贝级别等。
定位开销包括但不限于：
资源开销，例如，收发PRS的时频资源的开销；
信令开销，在收发PRS的下发和定位结果的上报过程中都存在信令开销；
功率开销，例如，发射PRS的功率较大，则功耗开销大。
例如，不同套PRS配置的至少以下之一不同：
PRS的发送周期；
PRS的发送带宽；
PRS的发送资源。
发送周期越大，则相邻两次发送PRS的时间间隔越大。
PRS的发送带宽越大，则发送一次PRS在频域占用的资源就越大。
PRS的发送资源包括但不限于时域资源和/或频域资源。
例如，对定位测量的测量精度，则可能发送的PRS的次数或者资源数量越多。若为了减少信令开销，则可能发送PRS的次数或资源数量就越少。总之，可以根据本次定位或者当前时段内定位需求从多套备用的PRS配置中选择一套PRS配置进行定位测量。
在进行定位测量时，基站发送PRS；UE接收PRS；UE根据对PRS的接收结果，实现对UE的定位。
在一些实施例中，下发携带有多套PRS配置的第一配置信息，包括：向基站或收发点TPR下发携带有第一配置信息的广播辅助消息；和/或，向用户设备UE下发携带有第一配置信息的定位辅助消息。
LMF可以根据对当前待定位的UE的定位需求，并结合当前下发的多套PRS配置中，各套PRS配置能够满足的定位需求，向基站或者TPR或者UE指示当前定位使用的是哪一套PRS配置。例如，方法还包括：下发第一指示信息，其中，第一指示信息，指示从多套PRS配置中选择用于定位的PRS配置。
例如，若第一指示信息是通过LPP消息下发的，则第一指示信息是指示UE从多套PRS配置中选择一套PRS配置用于定位测量。若第一指示信息是通过NRPPa消息下发的，则第一指示信息是用于指示基站或TPR从多套PRS配置中选择一套PRS配置用于定位测量。
此时，在一个实施例中，下发第一指示信息，包括：通过广播辅助消息向基站或TRP下发第一指示信息。
在另一个实施例中，通过定位请求消息向用户设备UE下发第一指示信息，其中，定位请求消息还携带有触发UE定位的触发指令。
在还有一些实施例中，LMF既向基站或TPR下发第一指示信息，也可以同时向UE下发第一指示信息，指示给基站或TPR下发的第一指示信息通过NRPPa消息携带，而给UE的第一指示信息由LPP消息携带。
在一些实施例中，方法还包括：
下发携带有重配置的第二配置信息；第二配置信息包括：至少一套更新后的PRS配置，或，第二指示信息；第二指示信息，指示待更新的至少一套PRS配置。
若该第二配置信息可以直接携带更新后的PRS配置，如此，基站接收到该PRS配置之后，直接可以利用第二配置信息中的PRS配置替换待更新(即失效的)PRS配置。
在一些实施例中，该第二配置信息可以称之为重配置信息。
若该第二配置信息仅携带了第二指示信息，第二指示信息可指示了如何更新之前根据第一配置信息配置的一套或多套PRS配置。例如，该第二指示信息携带更新前后PRS配置的偏移量。例如，PRS配置1，更新前的周期为A；更信后为B；此时第二指示信息可携带B相对于A的偏移量。
方法还包括：向基站或收发点TPR下发携带有第二配置信息的广播辅助消息。
该第二配置信息也可以是通过广播辅助消息下发的。如此，基站或TPR可以通过与LMF之间的NRPPa消息接收到该广播辅助信息。
例如，方法还包括：
接收第二配置信息的确认信息，其中，确认信息，用于指示确定收到第二配置信息。
接收第二配置信息的确认消息，包括：接收基站或TRP发送携带有确认信息的NRPPa消息。
基站或TRP通过确认信息的发送，告知LMF目前接收到第二配置信息，或者，接收到第二配置信息已经更新了基站内的PRS配置。
在一些实施例中，方法还包括：
接收基站或TRP上报的第三指示信息，其中，第三指示信息，指示基站或TPR从多套PRS配置中选择的用于定位的PRS配置。
基站或者TRP可以根据自身当前的负载和/或无线环境，比对各套PRS配置进行定位测量的负载量或者对无线环境的影响，可以选择出适合当前负载状况和/或无线环境的某一套或多套PRS配置作为推荐使用的PRS配置，然后向LMF上报第三指示信息。LMF接收到该第三指示信息之后，可以根据该第三指示信息确定一套用于当前定位的PRS配置。此处的当前定位包括但不限于：本次定位和/或当前时间段内的一次或多个次定位。例如，LMF可以根据第三指示信息向基站下发第一指示信息，第一指示信息中指示的用于定位的PRS配置，可以与第三指示信息指示的PRS配置中的一套或多套相同，也可以不相同。
例如，接收基站或TRP上报的第三指示信息，包括：
在未下发第一指示信息时，从基站或TRP接收第三指示信息；第一指示信息由LMF下发的，且用于指示从多套PRS配置中选择的用于定位的PRS配置。
例如，LMF当前对定位没有明确的需求，可能就不会下发第一指示信息，或者尚未来的及发送第一指示信息时，会去接收基站或TPR发送的第三指示信息。后续LMF可以根据第三指示信息下发第一指示信息。或者，LMF同意基站建议的PRS配置用于定位时，可以通过反馈信息的下发告知基站。
例如，该反馈信息可是确认信息，确认信息用于指示同意基站或TPR建议的PRS配置用于定位。
再例如，该反馈信息可以是否认信息，否认信息表示LMF不同意基站或者TPR通过第三指示信息建议的PRS配置。在这种情况下，LMF可以继续通过第一指示信息的下发，专门指示LMF想要基站或TPR使用的PRS配置。
参考图3B所示，本实施例提供过一种PRS配置处理方法，包括：
S210：向基站或TPR下发NRPPa消息，该NRPPa消息携带有多套PRS配置的第一配置信息。且这多套PRS配置为同一个基站的配置；或者，该多套PRS配置为同一个TPR的配置。
不同套PRS配置所满足的定位精度不同；和/或，不同套PRS配置所需的定位开销不同。
不同套PRS配置的至少以下之一不同：PRS的发送周期；PRS的发送带宽；及PRS的发送资源。
在一些实施例中，基站或TRP接收到的NRPPa消息除了携带第一配置信息以外，还可携带有第一指示信息。该第一指示信息向基站或TPR指示了多套PRS配置中用于当前定位的PRS配置。
当然在一些实施例中，第一指示信息和第一配置信息可以在同一条NRPPa消息中下发，减少LMF和基站或者LMF和TRP之间的交互次数。
在一些实施例中，第一指示信息和第一配置信息可以在不同的NRPPa消息中下发。
例如，若LMF下发第一配置信息的同时，尚未确定第一指示信息，如此，通过两条NRPPa消息分别下发第一配置信息及第一指示信息。
如图3B所示，在一些实施例中，方法还包括：
S220：下发携带有第二配置信息的NRPPa消息；第二配置信息包括：至少一套更新后的PRS配置，或，第二指示信息；第二指示信息，指示待更新的至少一套PRS配置。
在一些实施例中，如图3B所示，方法还包括：
S230：接收第二配置信息的确认信息，其中，确认信息，用于指示确定收到第二配置信息。
在一些实施例中，如图3B所示，方法还包括：
S240：在未下发第一指示信息时，从基站或TRP接收第三指示信息；第一指示信息由LMF下发的，且用于指示从套PRS配置中选择的用于定位的PRS配置。
如图3D所示，本实施例提供一种PRS配置处理方法，包括：
S310：向UE下发定位辅助信息，其中，定位辅助信息由LPP消息携带，该定位辅助信息携带有多套PRS配置的第一配置信息，多套PRS配置对应于一个基站或一个TRP；PRS配置用于用户设备UE的定位测量。
此处的LPP消息是LMF通过基站透传给UE的。
在一些实施例中，定位辅助信息包括定位测量的小区标识和/或定位测量的基站标识；以及，定位测量的定位参考信号的资源位置信息。
在一些实施例中，小区标识可是：最后停留的服务小区或最后停留服务小区的邻小区的标识。
在另一些实施例中，基站标识可为：UE最后停留的服务小区的基站的标识，或者，最后停留服务小区的邻小区的基站的标识。
通过小区标识和/或基站标识，UE可以知道测量对象。在进行定位测量时，是对小区或基站发送的PRS进行测量。故UE在进行定位测量时，是需要了解到PRS的资源位置信息。该资源位置信息指示了PRS发送的时频资源。
不同套PRS配置所满足的定位精度不同；和/或，不同套PRS配置所需的定位开销不同。
例如，不同套PRS配置的至少以下之一不同：PRS的发送周期；PRS的发送带宽；及PRS的发送资源。
在一些实施例中，如图3C所示，方法还包括：
S320：通过定位请求消息向用户设备UE下发第一指示信息。该定位请求消息为LPP消息的一种，原定是用于指示UE进行定位测量的。
例如，UE接收到定位请求消息之后，将根据PRS配置进行定位测量并上报定位结果。在本申请实施例中，由于UE从LMF接收了一个基站或一个TRP的多套PRS配置，在定位请求消息中还携带有指示当前定位使用哪一条PRS配置的第一指示信息。如此，该定位请求消息不仅会出发UE进行定位测量，还会告知UE基于哪一套PRS配置进行定位测量。
例如，UE的定位测量包括但不限于：
UE根据第一指示信息指示的PRS配置，在对应的时频资源上接收基站或TPR下发的PSR。
如图4A所示，本公开实施例提供一种定位参考信号PRS第一配置信息处理方法，其中，包括：
S410：接收携带有多套PRS配置的第一配置信息，其中，多套PRS配置对应于一个基站或一个TRP；PRS配置，用于用户设备UE的定位测量。
LMF会下发携带有多套PRS配置的第一配置信息，如此，基站或者TPR或者UE会接收到同一个基站或者TPR的多套PRS配置。
在一些实施例中，方法还包括：
S420：接收第一指示信息，第一指示信息，用于指示从多套PRS配置中选择用于定位的PRS配置。
接收的多套PRS配置，其中，不同套PRS配置所满足的定位精度不同；和/或，不同套PRS配置所需的定位开销不同。
多套PRS配置的不同，包括但不限于：不同套PRS配置的至少以下之一不同：PRS的发送周期；PRS的发送带宽；PRS的发送资源。
LMF与基站或TPR直接的通信可能遵守的是NRPPa协议，而LMF与UE之间的通信遵守的是LPP协议，故以下区分两种协议所对应的接收主体不同，进行举例说明。
如图4B所示，本申请实施例提供一种应用于基站或者收发节点TRP中的定位参考信号PRS配置处理方法，包括：
S510：接收携带有第一配置信息的广播辅助消息，该第一配置信息携带的多套PRS配置。这多套PRS配置中的多套PRS配置属于同一个基站或者属于同一个TRP。例如，第一配置信息有M套PRS配置，其中，N1套属于基站1，N2套属于基站2。N1和N2都为等于或大于2的正整数。不同基站或TPR的多套PRS配置可以部分相同也可以安全相同。
例如，基站和TPR共S个无线网接入节点接收到该NRPPa消息，则该NRPPa消息携带M套PRS配置的第一配置信息，这M套都属于每一个无线网接入节点，则每一个基站或TPR都有M套PRS配置。当然，也可以是M套中的多套属于其中一部分无线网接入节点，另外多套属于剩余一部分无线网接入节点。
总之，LMF下发给基站或TRP的广播辅助消息中携带的第一配置信息，可包括：给一个基站的多套PRS配置，或者给一个TPR的多套PRS配置。如此，单个基站或者单个TRP接收到的广播辅助消息中携带的第一配置信息，可为LMF为自身配置的多套PRS配置。
不同套的PRS配置的定位精度不同，和/或，定位开销不同。基站在于UE配合进行UE的定位测量时，可以根据当前UE的定位测量的精度需求和/或开销限制等，从多套PRS配置中选择出适合当前定位测量的PRS配置，以满足不同定位测量的定位需求，提高定位测量的服务质量 (Quality of Service，QoS)等。
如图4B所示，方法还包括：
S520：响应于广播辅助消息未携带有第一指示信息，从多套PRS配置选择一套用于定位的PRS配置；其中，第一指示信息由LMF下发的，且用于指示从套PRS配置中选择的用于定位的PRS配置；
S530：上报第三指示信息，其中，第三指示信息，用于指示基站或TPR选择用于定位的PRS配置的。
若NRPPa消息未携带第一指示信息，则基站或TPR自行确定一套用于定位PRS配置，与UE配合进行UE的定位。
此时，基站或TPR会将自行确定的或者建议使用的TPR配置，通过第三指示信息上报。此处上报第三指示信息的也可以是NRPPa消息。
基站或TRP上报了第三指示信息之后，基站或TPR会接收到LMF根据第三指示信息下发的第一指示信息和/或反馈信息，如此，基站或TPR可以根据第一指示信息和/或反馈信息指示的用于定位的PRS配置，知晓本次或当前时段内用于定位的PRS配置。在一些实施例中，广播辅助消息还携带有第一指示信息；方法还包括：根据第一指示信息，从多套PRS配置中选择用于定位的PRS配置。
任意NRPPa消息中携带有第一指示信息，则基站或TPR根据第一指示信息从多套PRS配置中选择出用于定位的PRS配置。此时，基站或TRP可以不用上报第三指示信息。如果当前基站需要配合UE进行定位测量，则根据第一指示信息指示的PRS配置，进行PRS的发送，转发基站通过对PRS定位测量形成的定位结果。例如，通过透传或非透传的方式，将UE的定位结果发送给LMF。此处的定位结果包括但不限于：具体的位置信息(例如，经纬度信息)和/或对PRS的测量结果，例如，PRS的接收功率信息等。
在一些实施例中，如图4C所示，所述方法还包括：
S610：接收RRC连接态的UE发送的按需***on-demand SI的请求信息；
S620：根据第一指示信息及请求信息，通过RRC消息向UE发送携带有用于定位的PRS配置的***消息。
如果基站处于RRC连接态下，则基站或TPR，分别与UE之间的信息交互比较灵活，为了减少信令开销，若接收到UE的请求消息，基站或TPR会结合第一指示信息和请求信息，通过RRC消息仅向UE发送用于定位的PRS配置。
在一些实施例中，如图4D所示，所述方法还包括：
S710：接收UE发送的按需***on-demand SI的请求信息；
S720：基于请求信息，广播携带有第一配置信息的***消息，并发送携带有第四指示信息的RRC消息；其中，第四指示信息是根据第一指示信息确定的，指示从多套PRS配置中选择的用于定位的PRS配置。
基站或TPR接收到请求信息之后，会广播***消息，如此UE根据通过广播的***消息的接收，就知道当前该基站或该TPR的多套PRS配置。基站或TPR还会通过RRC消息下发第四指示信息。此处的第四指示信息和第一指示信息都指向同一套用于定位的PRS配置，但是指示比特的指示方式可能不同，携带第四指示信息和第一指示信息的IE不同。
在本实施例中发送on-demand SI的请求信息的UE可以处于RRC连接态、RRC空闲态或者RRC非激活态。
在一些实施例中，RRC消息包括：
携带有第四指示信息的第一指示IE；其中，第四指示信息是根据第一指示信息确定的，指示从多套PRS配置中选择的用于定位的PRS配置。
在RRC消息中引入了一个专用的第一指示IE，该IE内可包括比特 序列，比特序列中的一个比特可对应于一套PRS配置，可以通过该比特的比特值，指示某一套的PRS配置是否用于定位。
在一些实施例中，请求信息为：UE在基站或TPR未广播包含PRS配置的***消息或者已广播包含多套PRS配置的***消息时发送的。
在一个实施例中，UE收到了LMF下发的触发UE进行定位测量的定位请求消息，但是还不知道PRS配置，此时UE会上报on-demand SI的请求信息。
在另一个实施例中，UE收到了LMF下发的触发UE进行定位测量的定位请求消息，也接收了基站或TPR下发的多套PRS配置，但是当前不知道用哪一套PRS配置进行定位测量，此时，UE均会上报on-demand SI的请求信息。
上述通过上报on-demand SI的请求信息，向基站或TPR请求多套PRS配置，或者，请求第四指示信息的UE，可处于RRC连接态，也可以处于RRC空闲态或者RRC非激活态。
在一些实施例中，方法，还包括：
接收RRC空闲态或RRC非激活态的UE的随机接入请求；
响应于携带有第一配置信息的请求信息的随机接入请求，广播携带有第一配置信息的***消息，并向RRC空闲态或RRC非激活态的UE发送携带有第五指示信息的随机接入响应RAR；其中，第五指示信息是根据第一指示信息确定的，指示从多套PRS配置中选择的用于定位的PRS配置。
若UE处于RRC空闲态或RRC非激活态，UE可以通过随机随机接入过程来下发第一配置信息和/或第五指示信息。
此处的随机接入可为2步随机接入或4步随机接入。
在本申请实施例中，例如，UE通过2步随接入的消息(Message， Msg)A携带请求辅助信息的请求信息。如此，基站或TPR就会接收到MsgA，若发现MsgA中携带有请求信息，则会通过随机接入响应，例如，MsgB向UE返回携带有辅助信息的消息。
在本申请实施例中，例如，UE通过4步随接入的消息(Message，Msg)1携带请求辅助信息的请求信息。如此，基站或TPR就会接收到Msg1，若发现Msg1中携带有请求信息，则会通过随机接入响应，例如，Msg2或Msg4向UE返回携带有辅助信息的消息。
例如，基站在随机接入响应(Random,Access Response,RAR)中携带辅助信息。在RAR的MAC RAR中携带辅助信息。
在一些实施例中，针对请求辅助信息的随机接入请求，随机接入响应中可携带随机接入前导码(Random Access Preamble，RAP)(Identity，ID)标识以及第五指示信息。
在一些实施例中，第五指示信息和第一指示信息的作用相同；但是第五指示信息的信息内容和第一指示信息的信息内容可相同或不同。第五指示信息和第一指示信息的信息格式可相同或不同。
在一些实施例中，RAP ID和第五指示信息可以携带在相同的IE中，例如，携带在原本用于携带RAP ID的IE中预留比特中。
在另一些实施例中，RAR中增加一个新的IE或者单独使用一个专用IE来携带第四指示信息。例如，在一些实施例中，RAR包括：第二指示IE，携带有第五指示信息。
该第二指示IE可为RAR中新增IE或者RAR中预留IE。
在一些实施例中，在RAR中新增MAC子(sub)协议数据单元(Protocol Data Unit，PDU)携带第五指示信息。
在一些实施例中，第二指示IE携带有：用于本次定位的PRS配置的配置标识；其中，多个通信节点共用配置标识所标识的PRS配置；通信 节点为：基站和/或TRP；
或者，
第二指示IE携带有通信节点的节点标识，其中，节点标识与PRS配置具有对应关系。
在一些实施例中，前述的第一指示IE同样可携带有：用于本次定位的PRS配置的配置标识；其中，多个通信节点共用配置标识所标识的PRS配置；通信节点为：基站和/或TRP；或者，第一指示IE同样可携带有通信节点的节点标识，其中，节点标识与PRS配置具有对应关系。
例如，相邻的X个基站有共用的至少一套PRS配置，若使用该套PRS配置进行UE的定位测量时，在第一指示IE和/或第二指示IE中可携带该套PRS配置的配置标识。若此，UE接收到该PRS配置的配置标识时，将认为多个基站或TRP共用这一套PRS配置对其进行定位测量。例如，UE通过与3个基站或TPR的信号交互，完成对自身的定位测量。此时，若UE接收到的第一指示IE携带有一套PRS配置的配置标识，则UE认为3个基站均是采用这一套PRS配置下发PRS，从而进行定位测量。
在有些实施例中，基站的基站标识或TPR的TRP标识，与PRS配置建立有对应关系。不同的通信节点对应的PRS配置可相同或不同。例如但不限于：一个基站或TPR都有默认使用的PRS配置，或者，优先使用的PRS配置，此时，基站或TPR就可以与默认使用的PRS配置或者优先使用的PRS配置建立对应关系。若使用默认PRS配置或者优先PRS配置时，则可以携带作为通信标识的基站标识或者TRP标识就好，如此，UE接收到携带有通信标识的第一指示IE，会根据基站或TPR预先下发的对应关系的指示信息，确定出各个基站或TPR的节点标识确定出使用哪一套PRS配置进行定位测量。
在另一个实施例中，第一指示IE和/或第二指示IE同时携带有节点 标识和配置标识；该节点标识用于指示参与UE定位测量的基站和/或TPR。配置标识可用于指示基站或TPR会使用的PRS配置。
在还有一些实施例中，所述第一指示IE和/或第二指示IE同时携带节点标识和配置标识，且是对应携带节点标识和配置标识；即一个节点标识对应于一个配置标识。例如，(TRP ID1，PRS configuration ID1)；(TRP ID2,PRS configuration ID3)。TRP ID1为TRP1的标识。TRP ID2为TRP的标识。PRS configuration ID1为PRS配置1的标识。PRS configuration ID3为PRS配置3的标识。此时，第一指示IE指示的TPR 1使用PRS配置1；TRP2使用PRS配置3。
在一些实施例中，方法还包括：
接收携带有第二配置信息的广播辅助消息；第二配置信息包括：至少一套更新后的PRS配置，或，第二指示信息；第二指示信息，指示待更新的至少一套PRS配置；
根据第二配置信息，更新至少一套PRS配置。
LMF通过广播辅助信息下发的第一配置信息时，LMF在需要更新一套或多套PRS配置时，会直接通过第二配置信息下发更新后的PRS配置，或者，下发更新一套或多套PRS配置的第二指示信息。
第二指示信息可为指示如何更新一套或多套PRS配置的信息。
在一些实施例中，方法还包括：响应于接收到第二配置信息，上报携带有确认信息的NRPPa消息，其中，确认信息，用于指示确认收到第二配置信息。
通过确认信息用于指示接收到LMF下发的第二配置信息，表明当前基站或TPR接收到第二配置信息，并更新了至少一套PRS配置。
在一些实施例中，广播辅助消息包括：新无线NR下行测量辅助信息单元IE；
其中，NR下行测量辅助IE中的NR下行定位参考信号辅助信息中包含第一配置信息。

在另一个实施例中，方法还包括：

如图4E所示，本公开实施例提供一种PRS配置处理方法，方法应用于用户设备UE中，包括：
S710：接收携带有第一配置信息的定位辅助消息；其中，多套所述PRS配置对应于一个基站或一个TRP；所述PRS配置用于用户设备UE的定位测量。
定位辅助消息为按照LPP协议下发的LPP消息。由LMF直接传输给UE，基站接收到LMF下发的定位辅助消息之后透传给UE。
如此，UE就可以直接从LMF接收到携带有一个基站或一个TRP多套PRS配置的第一配置信息。
在一些实施例中，该PRS第一配置信息处理方法还包括：
S720：接收定位请求消息，其中，定位请求消息包括：触发UE定位的触发指令和第一指示信息；
S730：根据第一指示信息，从多套PRS配置中选择出用于本次定位的PRS配置；
S740：根据触发指令及用于本次定位的PRS配置，进行定位测量。
在一些实施例中，定位请求消息包括：
第三指示IE，携带有第一指示信息。
下发了多套的PRS配置，在触发UE进行定位请求时，通过定位请求消息携带第一指示信息，从而向UE指示下发的多套PRS配置用哪一套进行定位测量。
在一些实施例中，第三指示IE携带有：用于定位的PRS配置的配置标识；其中，多个通信节点共用配置标识所标识的PRS配置；通信节点为：基站和/或TRP；或者，第三指示IE携带有通信节点的节点标识，其中，不同节点标识对应于不同PRS配置。
在一些实施例中，定位辅助消息，包括：
提供辅助数据IE，其中，提供辅助数据IE携带有第一配置信息。
本实施例提供的方法，网络能够更新PRS配置，并且能够快速通知 UE网络更新后的PRS配置，实现了动态的PRS配置，能够满足不同的定位需求，并且能够降低***开销，提升资源利用率。本实施例提供的方案可如下：
步骤1：网络(LMF)向UE发送定位辅助信息(LPP消息)，该定位辅助信息为UE预配置多个TRP的多套下行PRS配置。此处的下行PRS配置为前述任一实施例提供的PRS配置的一种。
例如，以OTDOA定位为例，在定位辅助(LPP Provide Assistance Data)消息中的提供辅助数据(ProvideAssistanceData)IE中存在NR-DL-TDOA-ProvideAssistanceData IE。
NR-DL-TDOA-ProvideAssistanceData IE包含：
NR-DL-PRS-AssistanceDataPerTRP IE，在该IE中，可以为UE配置多个TRP的多套下行PRS配置。
上述多套下行PRS配置能够满足UE不同定位需求和定位精度，例如，多套下行PRS配置包含了不同的PRS发送周期，不同的PRS发送带宽，不同的PRS资源ID等内容。
步骤2：网络向UE发送定位请求消息，在定位请求消息中指示出步骤1中定位辅助消息中的多套PRS配置的一种。
例如，可以通过新增IE，IE的不同取值来指示不同的PRS配置，即定位辅助信息中所有的TRP使用相同的PRS配置；或者新增IE，包含每个TRP ID，且每个TRP ID对应不同的值来指示不同的PRS配置。
步骤3：当UE收到网络发送的定位请求消息后，结合网络发送给UE的定位辅助信息，确定当前网络使用的PRS配置，从而完成定位测量。
步骤4：当网络需要重新配置下行PRS配置时，网络(LMF)向上述发送给UE的辅助信息中的所有基站/TRP发送下行PRS重配置请求(对应于前述实施例的第二配置信息)。
该重配置请求包含PRS第一配置信息，PRS第一配置信息为上述定位辅助信息中的多种PRS配置中的一种。
基站/TRP收到网络(LMF)发送的上述PRS重配置请求后，向网络发送确认消息(NRPPa消息)，并且按照收到的PRS配置发送PRS；
网络在发送给UE的定位请求中指示出更新后的网络的下行PRS配置。
本实施例中，步骤1、步骤2、步骤3及步骤4仅是区分不同的步骤，并不代表步骤的先后关系。
在一种情况下，步骤1至步骤4是顺序执行的。在另一情况下，步骤4可在步骤2和步骤3之前执行。在还有一种情况下，步骤2可在步骤1之前执行；此处的步骤执行顺序仅是举例，具体实现不局限于此。
本实施例通过在定位***消息中包含多套下行PRS配置，并且通过LPP消息，MAC RAR，RRC消息等方式通知UE当前网络所使用的PRS配置。同时，网络可以动态更新定位***消息中的PRS配置。此处的下行PRS配置为前述任一实施例提供的PRS配置的一种。
本实施例提供的方法可如下：
网络(LMF)向基站/TRP发送UE定位所需的广播辅助信息(NRPPa消息)，该广播辅助信息为UE预配置多个TRP的多套下行PRS配置；具体的，可以在定位***消息类型6-1(posSibType6-1)中的NR下行测量辅助IE(NR-DL-Measurement-AD)中的NR下行定位参考信号辅助信息(nr-DL-PRS-Assistance Data)中为多个基站/TRP配置多套下行PRS配置。此处的定位***消息类型6-1(posSibType6-1)为一种***消息。
上述多套下行PRS配置能够满足UE不同定位需求，定位精度和定位类型，例如，多套下行PRS配置包含了不同的PRS发送周期，不同的PRS发送带宽，不同的PRS资源ID等内容。
网络(LMF)可以指示基站/TRP使用多套下行PRS中的一种；具体的，网络可以在上述发送定位广播辅助消息时同时指示出基站/TRP使用某套下行PRS配置。
网络(LMF)向基站/TRP发送定位广播辅助信息重配请求，请求重配置下行PRS配置。具体的，该重配置消息可以为步骤1中同样的方式实现，或者仅仅发送一个指示信息，指示更新为步骤1中所发送的某种配置中的一种。
在一些情况下，由基站决定使用上述多套PRS配置中的一种，并将结果告知LMF。
当基站/TRP收到网络发送的定位所需的广播辅助信息后，则在定位***消息中广播多套下行PRS配置，并可向网络返回确认消息；并且按照步骤2中网络的指示，确定下行PRS配置，发送PRS信号。
一个方式是：网络向UE发送定位请求(例如LPP定位请求消息)，在定位请求消息中指示出步骤1中UE定位所需的广播辅助消息中的多套PRS配置的一种；具体的，可以通过新增IE的方式实现。另一个方式是：当RRC连接态UE通过on-demand SI的方式请求定位***消息时，如果基站使用广播的方式广播UE所请求的定位******，则向UE返回指示信息，指示基站广播的定位辅助信息中的多套PRS配置的一种；如果基站使用专用的方式发送定位***消息，则在该***消息中仅包含网络当前所使用的PRS配置(即多套PRS中的一种)。
又一个方式是：当RRC空闲态或非激活态UE通过on-demand方式请求定位***消息时，则向返回指示信息，指示基站广播的定位辅助信息中的多套PRS配置的一种。具体的，如果UE使用随机接入消息1请求，则基站在发送的MAC RAR中仅包含RAP ID和指示信息(可以通过定义一种新的MAC subPDU格式实现)；如果UE使用RRC***消息请 求(RRCSystemInfoRequest)消息请求定位***消息，则基站返回指示消息，指示基站广播的定位辅助信息中的多套PRS配置的一种。
再例如，上述指示信息可以有如下实现方式：通过新增IE，IE的不同取值来指示不同的PRS配置，即定位辅助信息中所有的TRP使用相同的PRS配置；或者新增IE，包含每个TRP ID，且每个TRP ID对应不同的值来指示不同的PRS配置。
UE根据收到的PRS配置指示信息来确定TRP的PRS配置或者TRP的第一配置信息，完成定位测量。
本实施例提供一种PRS配置处理方法可如下：
LMF向基站发送定位广播辅助信息，定位广播辅助信息中包含3套下行PRS配置，分别对应不同的定位需求，并指示基站当前使用第一种(应用于定位精度要求低，定位类型非紧急等情况，以降低PRS开销，提升***资源利用率)。
基站收到LMF发送的定位广播辅助信息后，在定位***消息中广播三种下行PRS配置，且应用第一种配置。
当需要对UE进行定位时，如果UE通过MSG1请求定位***消息，则基站在MAC RAR种指示基站当前使用的下行PRS配置为第一种。此处的定位***消息为前述***消息的一种，定位***消息为携带有第一配置信息的***消息。
UE根据指示的PRS配置完成定位测量。
如果网络有新的定位需求(例如高精度)，则LMF向gNB指示应用第三种配置，gNB收到请求后使用第三套PRS配置发送PRS。
此时，可以通过上述方式进行PRS配置更新。
如图5所示，本公开实施例提供一种PRS配置处理装置，其中，应用于定位管理功能LMF，包括：
