相关申请的交叉引用
本公开主张在2021年08月06日在中国提交的中国专利申请号No.202110904304.0的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,尤其涉及UL定位参考信号的激活方法、装置、终端及网络侧设备。
在第五代移动通信新空口(5th Generation Mobile Communication Technology New Radio,5G NR)定位技术中,重点支持了连接态终端的定位。后续增强中,研究终端在非连接态(包括无线资源控制(Radio Resource Control,RRC)空闲(IDLE)状态和非激活(inactive)状态)下进行定位。网络侧无法确定用户设备(User Equipment,UE)什么时候需要进行上行(Uplink,UL)定位,若网络侧提前激活了UL定位参考信号,会导致额外的功耗和资源浪费;若基于UE自主激活,网络侧无法确定UE何时开始传输UL定位参考信号,这会导致网络侧需要不停的去监听,甚至大范围的接收节点去盲听UL定位参考信号。因此无法确定何时去激活UL定位参考信号,导致终端耗电较高且网络侧资源消耗较高。

下面首先对本公开提供的方案涉及的内容进行介绍。
一、NR RRC状态
NR系统设计了3个RRC状态:空闲(RRC_IDLE)状态、连接(RRC_CONNECTED)状态和非激活(RRC_INACTIVE)状态。当终端和网络之间存在RRC连接时,终端处于连接状态或者非激活状态,否则终端处于空闲状态。RRC状态转换图1所示。在一个时刻,终端只能处于一种RRC状态。
(1)空闲IDLE状态具有以下特点:
终端可以接收基本系统信息,并根据系统配置,终端在空闲状态下也可 以发送SI请求来获取更多的系统消息;
在此状态下,终端通过监听5G-S-TMSI来获取核心网发送的寻呼消息;
使用终端自主控制的移动性管理机制,即在测量基础上终端自主决定进行小区选择和重选。
此时终端通过RRC连接过程转换进入RRC连接态。
(2)非激活INACTIVE状态具有以下特点:
基于网络的配置,执行终端控制的移动性,即终端可以在网络配置的区域内自主移动,无需通知网络;
终端保存AS的上下文;
终端还会通过监听寻呼信道,使用5G系统标识(5G-S-TMSI)接收核心网发起的寻呼消息,使用非激活的无线网络临时标识(Inactive RNTI,I-RNTI)来获取RAN发起的寻呼消息;
执行基于RAN通知区域(RAN-based Notification Area,RNA)的周期性更新,以及当终端移出RAN通知区域时的更新。
二、小数据传输方式(small data transmission,SDT)
NR中正在讨论如何在非激活态发送小数据。当中包括使用RRC signaling传输小数据,以及不使用RRC signaling(即w/o RRC signaling)方式传输小数据。其中使用RRC signaling传输小数据,即RRC Resume Request消息与所要传输的小数据包一起发送给网络侧,触发后续的流程。
当前的讨论过程中,认为使用RRC signaling传输非连接态小数据,当前的服务基站(serving gNB)可能不同于与锚点基站(anchor gNB)。在少量SDT的情况下,可能没有锚点转换的必要性。因此非连接态小数据传输过程中不进行锚点转换也是R17SDT立项中的其中一个目标。
不进行锚点转换情况下非连接态的小数据包只能由锚点gNB进行分组数据汇聚协议层(Packet Data Convergence Protocol,PDCP)的相关操作,包括加/解密和完整性保护/效验等。
三、定位流程如图2所示,概述如下:
基于外部定位服务实体,或者接入和移动管理功能(Access and Mobility Management Function,AMF)内部定位需求(例如为了紧急呼叫定位UE), 或者UE的触发,当前服务AMF收到定位服务请求;
AMF将定位服务请求发给某一个位置管理功能(Location Management Function,LMF);
LMF可能触发与新一代(new generation,NG)-RAN节点之间定位相关的过程,比如获得定位所需的辅助信息或者定位测量结果;LMF与NG-RAN节点之间使用NR定位协议A(NR Positioning Protocol A,NRPPa)进行通信;
LMF也可能触发与UE之间定位相关的过程,比如传输定位辅助信息给UE,获得UE上报的定位测量或者定位估计结果;LMF与UE之间使用定位协议(LTE Positioning Protocol,LPP)进行通过信;
LMF将定位服务响应发送给AMF;
AMF将定位服务响应发送给对应的定位服务触发端。
其中,终端在空闲IDLE状态或者非激活inactive状态UL定位,网络会给终端UE预配置相应的UL定位参考信号,当UE进入空闲IDLE状态或者非激活inactive状态后,基于这些预配置的UL定位参考信号进行上行参考信号的传输,从而减少UE耗电。但当网络为处于空闲IDLE状态或者非激活inactive状态UE预配置了UL定位参考信号后,无法确定何时去激活UL定位参考信号。基于以上,本公开提供了一种UL定位参考信号的激活方法、装置、终端及网络侧设备,用以解决相关技术中当网络为处于空闲IDLE状态或者非激活inactive状态UE预配置了UL定位参考信号后,无法确定何时去激活UL定位参考信号的问题。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
