定时误差关联信息的发送方法及装置
相关申请的交叉引用
本公开要求于2021年08月06日提交的申请号为202110904103.0，发明名称为“定时误差关联信息的发送方法及装置”的中国专利申请的优先权，其通过引用方式全部并入本文。
技术领域
本公开涉及无线通信技术领域，尤其涉及一种定时误差关联信息的发送方法及装置。
背景技术
在相关的定位方法中，UL-TDOA(Uplink-Time Difference Of Arrival，上行链路到达时间差)定位方法是一种重要的定位方法，其工作原理是：UE(User Equipment，用户设备或用户终端或终端设备)发送SRS-Pos(Sounding Reference Signal for Positioning，用于定位的探测参考信号)，UE附近的TRP(Transmit and Receive Point，收发点)接收并测量SRS-Pos的TOA(Time Of Arrival，到达时间)，TRP将获取的SRS-Pos的UL RTOA(Uplink Relative Time Of Arrival，上行相对到达时间)上报给LMF(Location Management Function，定位管理功能单元或定位服务器)，由LMF利用UL RTOA，得到UE与各TRP之间的距离。然后结合其他已知信息(例如TRP的地理坐标)，计算出UE的位置。
如上所述，对于UL-TDOA定位方法，在相关协议中，在计算UL RTOA等定位时间测量值时，协议中假设在天线连接器(Antenna Connector)位置进行时间测量，但是，实际上信号的时间测量位置在基带单元，因此存在时间测量误差，该误差对于SRS-Pos信号发送与信号接收都存在，被称为是发 送定时误差与接收定时误差。所述定时误差的存在，会导致包括UL-TDOA在内的所有基于时间的定位的测量结果不准确，从而影响了最终的定位精度。而且，这种收发定时误差与硬件链路有关并且是时变的，即不同射频链路或者不同时刻的测量结果，具有不同的收发定时误差。那么，当UE通过不同的射频链路或在不同的时刻发送SRS-Pos资源，该SRS-Pos资源会具有不同的发送定时误差，因而导致定位服务器LMF的定位精度低。

本公开实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并 不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在相关技术中NR(NR Radio Access，新无线接入技术)UL-TDOA定位方法中，UE服务基站先要给UE配置发送SRS-Pos的时间和频率资源，并将SRS-Pos的配置信息通知LMF。LMF将SRS-Pos的配置信息发给UE周围的TRP。各TRP根据SRS-Pos的配置信息去检测UE发送的SRS-Pos并获取SRS-Pos到达时间与TRP本身UL RTOA。UL-TDOA一般采用基于网络的定位方式，即各TRP将所测量的UL RTOA传送给LMF，由LMF利用各TRP提供的UL RTOA以及其他已知信息(例如TRP的地理坐标)来计算UE的位置。
UL-TDOA可采用与DL-TDOA(Downlink-Time Difference Of Arrival，下行到达时间差)类似的方法计算UE的位置。设共有N个TRP通过测量某个UE发送的SRS-Pos获得N个UL RTOA测量值RTOAi(i＝1,…,N)，RTOAi主要取决于UE与TRPi的距离、UE时钟与TRPi的时钟之间的时偏以及测量误差。若从这N个TRP中选某个TRP(例如TRPj)做为参考TRP，并用其余TRP测量的UL RTOA减去参考TRPj测量的UL RTOA，便得到N-1个的TDOA:TDOA_(i,j)＝RTOA_i-RTOA_j(i＝1,..,N；i≠j)。若TRPi的时钟与TRPj的时钟完全同步，则TDOA_(i,j)(当转换为距离时)代表了UE到TRPi与UE到参考TRPj的距离之差(若TRPi的时钟与TRPj的时钟不是完全同步，则TDOA_(i,j)还包括TRPi的时钟与TRPj的时钟之间的时偏)。UE与各TRP之间时偏的影响已在相减时被消除了。于是，与RSTD(Reference Signal Time Difference，参考信号时间差)测量类似，由每个TDOA_(i,j)测量值可构成一条双曲线：双曲线的焦点为TRPi和TRPj，双曲线的点到TRPi和TRPj的距离差为TDOA_(i,j)，UE位置为双曲线上的某个点。于是，与DL-TDOA类似，UE的位置可由计算N-1个TDOA测量值所构成的N-1个双曲线方程得到。如图1所述，示例由3个TRP获得UL-TDOA测量值来进行UE的2维定位的例子。
在相关技术中，如上所述，对于UL-TDOA定位方法，在相关协议中， 在计算UL RTOA等定位时间测量结果时，协议中假设在天线连接器(Antenna Connector)位置进行时间测量，但是，实际上信号的时间测量位置在基带单元，因此存在时间测量误差，该误差对于SRS-Pos信号发送与信号接收都存在，被称为是发送定时误差与接收定时误差。所述定时误差的存在，会导致包括UL-TDOA在内的所有基于时间的定位测量的测量结果不准确，从而影响了最终的定位精度。而且，这种收发定时误差与硬件链路有关并且是时变的，也就是说不同射频链路或者不同时刻的测量结果，具有不同的收发定时误差。那么，当UE通过不同的射频链路或在不同的时刻发送SRS-Pos资源，该SRS-Pos资源就会具有不同的发送定时误差，因此，就有必要将SRS-Pos资源与发送定时误差之间的关联信息通知给LMF，协助LMF完成定位计算。
在相关技术中，在UL-TDOA定位方法中，协议中并没有规定UE如何将SRS-Pos与发送定时误差之间的关联信息上报给定位服务器，包括LMF如何向UE请求该关联信息，UE如何向LMF上报该关联信息，以及关联信息具体包含有哪些内容以及关联信息的格式设计等。
因此提出了本公开的一种定时误差关联信息的发送方法，本公开的核心思想是UE将SRS-Pos资源或SRS-Pos资源集与发送定时误差信息之间的关联信息，直接或者间接上报给网络设备，协助网络设备完成UE定位。

具体的，在终端设备具有提供关联信息能力的情况下，在所述相应消息中携带所述关联信息，以免LMF或基站再发请求给终端提供关联信息，更有效网络利用资源。
LMF发送能力请求，UE上报能力方案，其流程示意图如图3所示。其中，关于UE上报能力的方案，主要有两种：
上报方案1：LMF向UE发送能力请求信令(NR-UL-RequestCapabilities-r17)，其中携带关联信息请求。在该信令中，LMF会请求UE的能力，并询问UE是否具有提供关联信息的能力。
UE在UE能力上报信令(NR-UL-SRS-Capability-r17)中，上报其是否具有提供关联信息的能力。
上报方案2：LMF向UE发送能力请求信令(NR-UL-RequestCapabilities-r17)，其中携带关联信息请求。在该信令中，LMF会请求UE的能力，并询问UE是否具有提供关联信息的能力。
UE在UE能力上报信令(NR-UL-SRS-Capability-r17)中，上报其是否 具有提供关联信息的能力，如果具有提供关联信息的能力，则直接在能力上报信令中提供该关联信息。
也就是说，相比上报方案1，上报方案2中UE不但会提供其是否具有提供关联信息的能力，而且如果UE具有该能力的情况下，还会直接在能力上报信令中提供该关联信息。通过这种方式，可以提前将关联信息上报给LMF，方便LMF做下一步的处理。
