R16中DL-PRS的配置流程介绍如下:
(1)、LMF从基站获取到基站预配置的DL-PRS资源后,基于这些DL-PRS配置信息来为UE配置相应的DL-PRS资源。
基站中每个TRP配置相应的DL-PRS资源。当有定位业务到达时,LMF从基站获取基站预配置的DL-PRS的配置信息。当LMF获取到基站的能力信息后,LMF从DL-PRS配置信息中选取部分DL-PRS资源,并将其作为定位辅助数据的一部分以通过提供辅助数据(ProvideAssistanceData)消息下发给UE,如图1所示。或者,当LMF收到UE的请求辅助数据(RequestAssistanceData) 消息后,LMF从DL-PRS配置信息中选取部分DL-PRS资源,并将其作为定位辅助数据的一部分以通过ProvideAssistanceData消息下发给UE,如图2所示。
A、LMF主动提供定位辅助数据信息给UE。
步骤1:LMF主动发送携带了DL-PRS配置信息的ProvideAssistanceData消息给UE。
B、UE从LMF请求获取定位辅助数据信息。
步骤1:UE发送RequestAssistanceData消息给LMF。
步骤2:LMF收到该消息后,发送ProvideAssistanceData消息给UE作为相应,其中携带DL-PRS的配置信息。
(2)、LMF获取基站预配置的DL-PRS资源。
基站配置相应的DL-PRS资源,当LMF需要获取基站配置的DL-PRS资源时,LMF发送TRP信息请求(Information Request)消息,请求获取基站下的TRP配置的DL-PRS资源,如图3所示。
步骤1:LMF发送TRP Information Request消息给基站(NG-RAN node),请求获取基站下的TRP配置的DL-PRS资源。
步骤2:基站发送TRP信息响应(information Response)响应消息给LMF,并在响应消息中携带基站下的不同TRP配置的PRS资源的配置信息。
下行RAT相关的定位技术主要是基于下行定位参考信号(DL-PRS)来进行测量,并依据测量结果来计算获取相应的位置信息。但是,即使当前没有定位业务或者存在未被终端使用的DL-PRS时,基站中的每个TRP仍然会传输其预配置的所有的DL-PRS信号,这种情况下,会造成PRS资源的浪费。另外,基站中的TRP在配置PRS时是基于每个cell来配置的,会导致UE的定位精度不够,导致定位失败。
本申请实施例提供的技术方案中,LMF基于预配置的可用的PRS配置信息,进一步可以根据本地策略,以及来自UE或其他网络节点的辅助信息,来触发PRS配置变更,从而实现灵活动态的配置DL-PRS,以提高网络效率, 和保障定位精度。其中,所述预配置的可用的PRS配置信息,可以是预配置的可动态变更的PRS配置信息,即可以随时根据需要进行变更,不是预先固定设置好的。
下面分别从不同设备侧进行具体说明。
LMF侧行为:
当有定位业务需求(来自核心网,例如AMF发送的定位业务需求)时,针对与该定位业务需求关联的小区或TRP,LMF基于预配置的可动态变更(即可以随时更新的,不是预先固定配置无法更新的)的PRS配置信息,根据本地策略(具体可以根据实际需要而定,本申请不进行限制),结合定位业务的QOS(Quality of Service,服务质量)需求,例如:精度,时延等,产生针对UE的PRS配置信息,并通过LPP(LTE Positioning Protocol,LTE位置协议):提供辅助数据(Provide Assistance Data)消息或其他新定义的消息发送给UE,该消息包括以下至少一项(即所述PRS配置信息包括以下至少一项):
动态配置的DL-PRS资源对应的部分带宽(BWP)标识(ID);
动态配置的DL-PRS资源对应的定位频率层ID;
动态配置的DL-PRS资源对应的基站ID;
动态配置的DL-PRS资源对应的TRP ID;
动态配置的DL-PRS资源集ID;
动态配置的DL-PRS资源ID;
动态配置的DL-PRS资源周期的集合;
动态配置的DL-PRS资源周期使用的重复次数的集合;
动态配置的DL-PRS资源静默格式(muting pattern)的集合。
需要说明的是,关于本申请实施例中所述的动态配置,所谓动态用来说明这样的配置是可以动态改变的,而不是一次配完永远固定不变,而所谓配置用来说明这样的行为:发送方在消息中携带一些参数(上述任一所述参数),而接收方根据这些参数完成指定的行为。也就是说,本申请实施例中所述PRS配置信息,都是可以动态变更的,不是固定不变的,用于指示接收方执行相 应的操作。
当LMF基于预配置的可动态变更的PRS配置信息,决定配置或变更该PRS配置信息相关的小区或TRP(即PRS资源分配对象)上的PRS配置资源时,LMF产生针对该小区或TRP的PRS配置信息,并通过NRPPa(NR Positioning Protocol A,NR位置协议A):位置信息请求(POSITIONING INFORMATION REQUEST)或其他类似的消息发送给gNB,该消息包括以下至少一项(即所述PRS配置信息包括以下至少一项):
添加或变更或删除的DL-PRS资源对应的BWP ID;
添加或变更或删除的DL-PRS资源对应的定位频率层ID;
添加或变更或删除的DL-PRS资源对应的基站ID;

若LMF收到gNB发送的NRPPa:位置信息响应(POSITIONING INFORMATION RESPONSE)或其他类似的消息,则:
若返回的是配置成功或部分成功信息,则根据这些信息,从配置成功的PRS资源中选择针对相应UE的PRS配置或变更信息。其中,基站反馈的成功,可能是全部成功,也可能是部分成功,例如:配了10个RB,但仅成功5个RB,但在选择将使用的PRB时,只能从成功的资源中选择;变更信息,是相对先前的配置资源的变更(包括删除或添加),例如:先前配置了PRB1,2,3,而变更信息可能是删除了PRB 2,或增加了PRB 4。
若返回的是配置失败信息,则从其他实际可用的PRS资源中选择针对相应UE的PRS配置或变更信息,或者根据本地策略(具体可以根据实际需要而定,本申请不进行限制),选择其他定位方法(具体可以根据实际需要而定,本申请不进行限制)等。
可选的,移动性管理功能实体(Access and Mobility Management Function,AMF)向LMF发送的定位请求消息中,包含UE的优先级信息,这样,LMF在进行动态的PRS资源配置时,可依据此优先级信息,决定配置合适的PRS资源给gNB和UE。
可选的,当LMF基于预配置的可动态变更的PRS配置信息,决定逐个(per)UE地配置或变更关联小区或TRP上的PRS配置资源时,LMF产生针对该关联小区或TRP的Per UE(即针对每一UE)的PRS配置信息,并通过NRPPa:POSITIONING INFORMATION REQUEST或其他类似的消息发送给gNB,该消息包括以下至少一项(即所述PRS配置信息包括以下至少一项):

添加或变更或删除的Per UE的DL-PRS资源重复次数的集合;
添加或变更或删除的DL-PRS资源muting pattern的集合;
可选地,还包含UE的优先级信息。
若LMF收到gNB发送的NRPPa:POSITIONING INFORMATION RESPONSE或其他类似的消息,则:
根据消息中携带的per UE的PRS资源配置结果,从配置成功的PRS资源中选择针对相应UE的PRS配置或变更信息。
若返回的是配置失败信息,则从其他实际可用的PRS资源中选择针对PRS资源配置失败的UE的PRS配置或变更信息,或者根据本地策略(具体可以根据实际需要而定,本申请不进行限制),选择其他定位方法(具体可以根据实际需要而定,本申请不进行限制)等。
