技术领域
本申请涉及通信技术领域，尤其涉及一种TSN参考时间的时延补偿方法、装置及设备。
背景技术
5G网络从时间敏感型网络(timesensitive network，TSN)时钟获得TSN参考时间再发送到TSN工作域，用作TSN工作域的时延校正。TSN参考时间在5G网络中的传输会经历时延，因此TSN参考时间需要经过校正后再用于TSN工作域的时间参考。
目前一般认为可基于时间提前量(TA)对TSN参考时间进行校正。但是目前基于TA对TSN参考时间进行校正存在以下两个问题，导致基于TA的补偿精度会出现误差：
(A)TA的评估和产生完全属于基站实现，基站为一个终端产生TA时，瞄准的上行时隙或符号的接收信号到达时间不一定正好是下行时隙的结束时间。
(B)根据目前的TA的颗粒度，TA的误差在[-8,+8]·T C/2 μ，目前参考子载波间隔(SCS)＝15KHz,μ＝0,TA的精度误差在260ns，考虑其他误差，目前普遍认为经过一次5G空口传输的时延误差在540ns。

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地描述，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。

以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如，可以按不同于所描述的次序来执行所描述的方法，并且可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
请参见图1，图1示出本申请实施例可应用的一种无线通信***的框图。无线通信***包括终端11和网络侧设备12。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)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本申请实施例中并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信***中的基站(例如：eNB、WLAN接入点、或其他接入点等)，或者为位置服务器(例如：E-SMLC或LMF(Location Manager Function))，其中，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，但是本申请实施例并不限定基站的具体类型和具体通信***。
如图2所示，为时间敏感型网络(timesensitive network，TSN)参考时钟从TSN工作域(右侧)经5G网络传输到TSN终端站(end stations)(左侧)的情形。网络侧TSN翻译器(NW-TT)会记录收到TSN参考时间的时间点(即ingress time)，该时间点以5GS(即5G***)的内部时间记录；当该参考时间传输到左侧UE后，设备端TSN转换器(DS-TT)会记录接收到TSN参考时间的时间点(即egress time)，该时间点同样以5GS的内部时间记录，后 者减去前者的时间差可以用来补偿TSN参考时间在5G网络的传输时延，两者的精确度决定了5G网络传输时延估计的精确度。TSN终端站使用经过时延补偿的TSN参考时间来校对其当地时钟。在参考子载波间隔(sub-carrier space，SCS)是15KHz的情况下，一次空口传输带来的时延误差是540ns。其中，gNB为基站，5G GM(Grandmaster)为5G***时钟，UPF(User Plane Function)为用户面功能实体，TSN GM为TSN参考时钟，TSN working Domain为TSN工作域。
5G网络传输时延补偿的精确度影响TSN参考时间校对的精确度。当前5G网络传输时延较大一部分来自空口，图2中显示了TSN参考时间从NW-TT(network time translator)到DS-TT(device side time translator)经历了一次空口传输。
此外如图3所示，TSN参考时间在5G网络中从NW-TT到DS-TT经历两次空口传输，带来的总的时延估计误差为1080ns，再加上有线部分的每跳时延估计误差是40ns，导致最大时延误差超出允许的最大时延误差——900ns。
目前，时间提前量(Timing Advance，TA)用来校正UE的上行发送时间，使得上行发送信号到达基站接收机后，上行信号的起始点跟基站设定的上行信号的接收起始点相匹配。在基站中，理想的情况是上行信号到达的起始点正好是下行发送信号的起点；然而，基站的上下行时隙时间对齐的程度当前协议并没有规定，原则上基站可以根据其收发信机的状态调整限制和基带数字信号处理器的处理时序限制，在一定范围内(如循环前缀(Cyclic Prefix，CP)之内)确定想要的上行信号到达时间，然后通过TA命令把上行信号到达时间调整到目标时间点。此时，TA体现的不仅有电波在空口的传输时延，还有基站想要到达的上下行时间偏移。图4显示了TA调整上行发送时间和真实传输时延(Td)的关系示例：基站想要的上行信号到达时间点滞后与下行时隙结束点Δ，假设UE通过TA/2来确定相对于下行时隙接收起点的提前量，则TA/2＝Td-Δ/2。其中，gNB DL TX timing为基站下行发送时间，gNB UL RX timing为基站上行接收时间，UE DL RX timing为终端下行接收时间，UE UL TX timing为终端上行发送时间，PDSCH为物理下行链路共享信道，PUSCH为物理上行链路共享信道。在另外一些情况下，基站的下行发送定时 会出现偏差，即基站下行信号的发送时序跟理想的定时时序有一些偏移，这些偏移可以是基站内部的射频单元引起，如发射天线之间的不完全同步会导致发射信号偏移，另外不同载波之间由于硬件性能的限制不完全同步等。
5G网络从TSN时钟获得TSN参考时间再发送到TSN工作域，用作TSN工作域的时延校正。TSN参考时间在5G网络中的传输会经历时延，因此TSN参考时间需要经过校正后再用于TSN工作域的时间参考。
目前一般认为可基于TA/2对TSN参考时间进行校正。但是目前基于TA对TSN参考时间进行校正存在以下两个问题，导致基于TA的补偿精度会出现误差：
(A)TA的评估和产生完全属于基站实现，基站为一个UE产生TA时，瞄准的上行时隙或符号的接收信号到达时间不一定正好是下行时隙的结束时间。
(B)根据目前的TA的颗粒度，TA的误差在[-8,+8]·T C/2 μ，目前参考SCS＝15KHz,μ＝0,TA的精度误差在260ns，考虑其他误差，目前普遍认为经过一次5G空口传输的时延误差在540ns。
基于问题A，目前的TA反映的不仅仅是电波在空口的传播时延，且反映了基站收发的时间关系；基于问题B，TA的精度相对于TSN参考时间在5G网络传输中允许的误差范围来说，比较大；综合考虑以上两个因素，基于TA的TSN参考时间传输时延补偿需要改进。
另外，在TSN参考时间经历两次空口传输时，带来的时延补偿误差会超过900ns的上限，需要增强。
本申请实施例提供一种时间敏感型网络TSN参考时间的时延补偿方法，如图5所示，包括：

Z＝μ+TA/2；
Z＝μ。
一些实施例中，在所述终端到网络侧设备的路损小于预设门限值时，Z＝μ。
一些实施例中，若所述终端获取到的时延补偿参数包括***消息中的第一时延补偿参数和所述第一专用信令中的第二时延补偿参数，所述终端优先使用所述第二时延补偿参数计算所述时延补偿值。
本申请实施例还提供了一种时间敏感型网络TSN参考时间的时延补偿方法，如图6所示，包括：
步骤201：网络侧设备向终端发送TSN参考时间的时延补偿参数。
在本申请实施例中，网络侧设备向终端发送TSN参考时间的时延补偿参数，终端根据时延补偿参数生成TSN参考时间的时延补偿值，这样可以通过额外的时延补偿来提高TSN参考时间经历无线通信网络传输到TSN工作域终端的时延补偿精度。
一些实施例中，所述网络侧设备向终端发送TSN参考时间的时延补偿参数包括以下至少一项：
通过***消息向所述终端广播所述时延补偿参数；
向所述终端发送第一专用信令，所述第一专用信令中携带所述时延补偿参数；
向所述终端发送切换请求响应消息，所述切换请求响应消息中携带所述时延补偿参数。具体地，可以是切换请求响应消息中包含切换命令，切换命令中携带所述时延补偿参数。
一些实施例中，所述***消息包括多个小区标识及与所述小区标识一一对应的时延补偿参数。
一些实施例中，所述第一专用信令包括以下至少一项：
无线资源控制RRC信令；
媒体接入控制MAC控制元素CE；
物理下行链路控制信道PDCCH承载的信令。
一些实施例中，所述网络侧设备向终端发送TSN参考时间的时延补偿参数之前，所述方法还包括：
接收所述终端发送的时延补偿配置请求，请求获取所述时延补偿参数。
一些实施例中，所述时延补偿参数包括以下至少一项：
由网络侧设备定时带来的偏移，包括上下行信号的时间偏移量μ，下行 发送时间偏移量，和/或上下行信号的时间偏移量与下行发送时间偏移量之和；
时间提前量TA精度误差补偿参数Ω。
一具体实施例中，网络侧设备(比如基站)可以通过***消息广播一个时延补偿量μ，用来补偿上下行信号的时间偏移量，这个时间偏移量对同一小区的所有UE是一致的，基站可以进行周期性的广播，节省信令开销，当然基站也可以通过专用信令将上下行信号的时间偏移量μ分别发送给每个终端。工业物联网(I-IoT)终端在收到上下行信号的时间偏移量μ后，可以通过以下两种方法生成TSN参考时间的时延补偿值：
方法1：基于收到的TA命令和上下行信号的时间偏移量μ生成TSN参考时间的时延补偿值。TSN参考时间的时延补偿值＝TA/2+μ。
方法2：不考虑TA，仅基于上下行信号的时间偏移量μ进行补偿：时延补偿值＝μ；这一方式适用于I-IoT终端距离基站较近，即到基站的路损小于预设门限的情形。
一具体示例中，可以在***信息块(System Information Block，SIB)中添加时延补偿参数。
另一具体示例中，在EN-DC(EUTRA-NR Dual Connection，以EUTRA为主，NR为辅的双连接)模式下，LTE cell可以为一个或多个NR cell广播时延补偿参数，多个NR cell的时延补偿参数可以放在一条消息中广播，每个NR cell的时延补偿参数对应一个小区标识和时延补偿值。
作为另外一种广播方式，基站可以使用PDCCH向多个I-IoT终端或小区所有的I-IoT终端广播时延补偿参数，比如上下行信号的时间偏移量μ。
另一具体实施例中，可以利用专用信令发送时延补偿参数，基站可以通过RRC信令，MAC CE或PDCCH向单个I-IoT终端发送时延补偿参数包括上下行信号的时间偏移量μ和/或TA精度误差补偿参数Ω，利用该时延补偿参数有如下实现方式：
方式1：时延补偿参数Ω仅补偿除上下行时间偏移之外的时延误差，例如TA精度误差；在这种情况下，I-IoT终端需要联合考虑***消息提供的上下行信号的时间偏移量μ(如果有)、TA和TA精度误差补偿参数Ω来生成TSN参考时间的时延补偿值:TSN参考时间的时延补偿值＝μ+TA/2+Ω；
方式2：该时延补偿参数Ω同时补偿上下行时间偏移和TA精度误差；在这种情况下，I-IoT终端需要联合考虑TA和时延补偿参数Ω来生成TSN参考时间的时延补偿值:TSN参考时间的时延补偿值＝Ω+TA/2；
方式3：专用信令中的时延补偿参数包括：上下行信号的时间偏移量μ，TA精度误差补偿参数Ω。跟方式1中类似，I-IoT终端需要联合考虑这两个参数和TA确定TSN参考时间的时延补偿值。对于同一个时延补偿参数，如果I-IoT终端收到***消息广播的对应于该参数的配置和专用信令发送的对应于该参数的配置，则I-IoT终端应该优先使用专用消息对该参数的配置。
方式4：对方式1、2和3，I-IoT终端在确定TSN参考时间的时延补偿值时，不考虑TA。这一方式适用于I-IoT终端距离基站较近，即到基站的路损小于预设门限的情形。
另外，I-IoT终端在初始接入5G***时，可以请求服务基站发送该时延补偿参数的配置或在接入流程中服务基站主动向I-IoT终端发送该时延补偿参数的配置。
另一个方面，I-IoT终端从一个5G小区切换到另一个5G小区(即目标5G小区)时，目标5G小区可以在切换请求响应消息(即切换命令)中包含所述时延补偿参数。I-IoT终端在与目标小区建立连接后，使用切换命令中收到的时延补偿参数生成TSN参考时间的时延补偿值。
另一具体实施例中，所述时延补偿参数也可以用来补偿基站的其他定时误差，例如下行发送时间偏移带来的误差。时延补偿参数可以包括下行发送时间偏移量(即下行帧开头的偏移)，I-IoT终端接收到TSN参考时间后，根据一个无线帧的开头来确定TSN和时延补偿值来确定有效TSN参考时间。基站在上述实施例中发给UE的时延补偿参数μ或Ω中，可以把下行帧开头的偏移也考虑进去。
上述实施例以NR I-IoT环境为例进行说明，本实施例的技术方案同样适用于TSN参考时间在LTE网络传输的时间补偿。
需要说明的是，本申请实施例提供的TSN参考时间的时延补偿方法，执行主体可以为TSN参考时间的时延补偿装置，或者该TSN参考时间的时延补偿装置中的用于执行加载TSN参考时间的时延补偿方法的模块。本申请实 施例中以TSN参考时间的时延补偿装置执行加载TSN参考时间的时延补偿方法为例，说明本申请实施例提供的TSN参考时间的时延补偿方法。
