具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
需要说明的是，本申请中所有获取信号、信息或数据的动作都是在遵照所在地国家相应的数据保护法规政策的前提下，并获得由相应装置所有者给予授权的情况下进行的。
为了保证上行正交性，基站要求来自同一子帧但使用不同频域资源的不同用户设备的信号到达基站的时间基本上是对齐的。基站只要在循环前缀(CP，Cyclic Prefix)范围内接收到用户设备发送的上行数据，就能够正确的解码上行数据。因此，在相关技术的上行同步机制中，基站通过向用户设备指示定时提前(TA，Timing Advance)量化值，来使得基站调整上行传输定时，进而使得来自同一子帧的不同用户设备的信号到达基站的时间都落在CP范围内。
目前，一种受网络控制的中继设备有望成为用来扩大小区覆盖范围的关键技术，可以称之为受网络控制的中继设备、能定向放大信号的中继设备、智能中继设备、网络辅助的中继设备、可控制的中继设备等等，以下均以中继设备代指。中继设备可以由两部分组成：RU(repeater unit)和MT(mobile terminal)，MT用来接收并处理基站发送的控制信号，具有部分UE的功能；RU用来转发来自基站或者UE的信号。
通过中继设备转发用户设备或基站发送的信号，能够有效地扩大小区的覆盖范围。而在使用中继设备转发信号的情况下，将影响相关技术中的上行同步机制。
为了解决上述问题，本公开实施例提供一种传输定时调整方法、装置。下面先介绍本公开实施例的实施环境。
图1是根据一示例性实施例示出的一种无线通信系统的示意图，如图1所示，该通信系统中包括若干个用户设备11、中继设备12以及基站13。
其中，用户设备11可以是指向用户提供语音和/或数据连通性的设备。用户设备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。用户设备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，用户设备11也可以是无人飞行器的设备。或者，用户设备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，用户设备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。
该中继设备12可以包括RU(repeater unit，响应单元)和MT(mobile terminal，移动终端)，MT用来接收并处理基站发送的控制信号，具有部分终端的功能；RU用来转发来自基站或者终端的信号。
此外，智能超表面(RIS，reconfigurable intelligent surface)，或者IRS(Intelligent Reflection Surface)也被称为“可重构智能表面”或者“智能反射表面”。RIS或者IRS可以灵活部署在无线通信传播环境中，并实现对反射或者折射电磁波的频率、相位、极化等特征的操控，从而达到重塑无线信道的目的。具体地，RIS可以通过预编码技术，将入射到其表面的信号反射到特定的方向，从而增强接收端信号强度，实现对信道的控制。
由于一般中继设备和RIS在网络交互时具有类似的特性，因此，中继设备12还可以是RIS以及IRS。
基站13可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(New Radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。
其中，基站13可以是4G系统中采用的演进型基站(eNB)。或者，基站13也可以是 5G系统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13的具体实现方式不加以限定。
各个用户设备11均能够与中继设备12通过无线空口建立无线连接，中继设备12也能够通过无线空口与基站13建立通信连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(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。
参照图1，用户设备11的信号经过中继设备12转发才能到达基站13，类似的，基站13发送的信号通过中继设备12转发才能到达用户设备11。值得说明的是，同一基站覆盖范围内的用户设备可以包括通过中继设备进行辅助通信的用户设备以及不需要通过中继设备进行辅助通信的设备，图1是以通过中继设备进行辅助通信的用户设备11进行的示意。
图2是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图2所示，包括：
S201、基站确定第一传输时延和第二传输时延，该第一传输时延为用户设备与中继设备之间的传输时延，该第二传输时延为该中继设备与该基站之间的传输时延。
S202、基站根据该第一传输时延和该第二传输时延向该用户设备发送定时提前TA量化值，该TA量化值用于该用户设备调整传输定时。
本公开实施例提供的传输定时调整方法的执行主体可以为基站。其中，该基站与中继设备通信连接，并，该中继设备与用户设备通信连接。本公开实施例中的基站可以是如图1所示的无线通信系统中的基站13，中继设备可以是图1所示的无线通信系统中的中继设备12，用户设备可以是图1所示的无线通信系统中的任意一个用户设备11。
在本公开实施例中，基站通过确定用户设备与中继设备之间的第一传输时延，以及，中继设备与基站之间第二传输时延，基于两条通信链路的传输时延向用户设备发送TA量化值以使得用户设备调整传输定时，以使得通信系统中存在中继设备时，基站可以准确地调整用户设备的传输定时，使得不同用户设备的信号到达基站的时间上是对齐的，避免因使用中继设备导致用户设备发送的信号无法实现上行同步。
图3是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图3所示，包括：
S301、基站确定第一传输时延和第二传输时延，该第一传输时延为用户设备与中继设备之间的传输时延，该第二传输时延为该中继设备与该基站之间的传输时延。
S302、基站根据该第一传输时延和该第二传输时延向该用户设备发送媒体接入控制层随机接入响应MAC RAR，该MAC RAR包括TA量化值，其中，该TA量化值占用12比特，该TA量化值的取值范围为0至N1，其中，N1大于3846且小于4096。
该MAC RAR(MAC payload for Random Access Response)可以是基站响应于用户设备的随机接入请求而发送的，用于在随机接入过程中调整用户设备的传输定时。该MAC RAR中包括的TA量化值可以是用于调整用户设备的传输定时的绝对量，即用户设备根据该TA量化量可以直接对用户设备当前的传输定时进行替换。例如，用户设备可以基于如下公式进行传输定时T TA的计算：
T TA＝(N TA+N TA,offset)*T c；
其中，N TA是该TA量化值，N TA,offset是基站发送的时间偏移量化值的和值，T c为预定 义的时间单位。
其中，参照图17所示的相关技术中的MAC RAR的示意图，MAC RAR包括Timing Advance Command(定时提前指令)字段，该字段可以包括TA量化值，在相关技术中，MAC RAR中的TA量化值的范围为(0～3846)，占用12比特。
此外，参照图17，MAC RAR还包括R(Reserved，保留)字段、UL Grant(up-link grant，上行链路授权)字段以及Temporary C-RNTI(临时C-RNTI)字段，其中，R字段为保留位，在相关技术中设置为“0”，UL Grant字段占用27比特，Temporary C-RNTI字段占用16比特。
采用上述方案，通过将MAC RAR中的TA量化值的取值范围由0～3846扩大到0至N1，N1大于3846且小于4096，有效地扩大了用户设备可调整的TA范围以适应存在中继设备的通信系统。即针对由于中继设备的使用造成的总的传输延时的增加问题，本实施例通过扩大TA量化值的取值范围，使得用户设备传输定时的调整范围更大，避免了因使用中继设备导致用户设备发送的信号无法实现上行同步的问题。
图4是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图4所示，包括：
S401、基站确定第一传输时延和第二传输时延，该第一传输时延为用户设备与中继设备之间的传输时延，该第二传输时延为该中继设备与该基站之间的传输时延。
S402、基站根据该第一传输时延和该第二传输时延向该用户设备发送媒体接入控制层控制单元MAC CE，该MAC CE包括TA量化值，其中，该TA量化值占用12比特，该TA量化值的取值范围为0至N2，其中，N2大于3846且小于4096。
该MAC CE用于在随机接入过程完成后的业务过程中调整用户设备的传输定时。该MAC CE可以是Timing Advance Command MAC CE(相对定时提前指令MAC CE)，该MAC CE中包括的TA量化值可以是用于调整用户设备的传输定时的绝对量。也可以是Absolute Timing Advance Command MAC CE(绝对定时提前指令MAC CE)，该MAC CE中包括的TA量化值也可以是用于调整用户设备的传输定时的相对量，例如用户设备可以基于如下公式对用户设备当前的传输定时N TA_old进行调整：
N TA_new＝N TA_old+(T A-x)*16*64/2 μ；
T A是用于调整用户设备的传输定时的相对量，x＝(M-1)/2，子载波间隔SCS为15*2 μ，M为T A的最大取值。
参照图18所示的相关技术中的相对定时提前指令MAC CE的示意图，该相对定时提前指令MAC CE包括TAG ID字段以及Timing Advance Command(定时提前指令)字段，其中，TAG ID字段用于表示被寻址TAG的TAG身份，该字段占用2比特。Timing Advance Command字段包括TA量化值，该字段占用6比特，该TA量化值的取值范围为0至61。
参照图19所示的相关技术中的绝对定时提前指令MAC CE的示意图，该绝对定时提前指令MAC CE包括多个R字段，即预留字段，以及Timing Advance Command(定时提前指令)字段。该Timing Advance Command字段包括TA量化值，该字段占用12比特，该TA量化值的取值范围为0至3846。
采用上述方案，通过将MAC CE中的TA量化值由范围(0～3846)扩大至0至N2，N2大于3846且小于4096，有效地扩大了用户设备可调整的TA范围以适应存在中继设备的通信系统。即针对由于中继设备的使用造成的总的传输延时的增加问题，本实施例通过扩大TA量化值的取值范围，使得用户设备传输定时的调整范围更大，避免了因使用中继设备导致用户设备发送的信号无法实现上行同步的问题。
图5是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图5所示，包括：
S501、基站确定第一传输时延和第二传输时延，该第一传输时延为用户设备与中继设备之间的传输时延，该第二传输时延为该中继设备与该基站之间的传输时延。
S502、该基站根据该第一传输时延和该第二传输时延向该用户设备发送媒体接入控制层随机接入响应MAC RAR，该MAC RAR包括TA量化值，其中，该TA量化值占用X1比特，其中，X1大于12。
采用上述方案，通过将MAC RAR的TA量化值占用的比特数提高至X1比特，使得该TA量化值相较于相关技术占用比特数更多，能够有效地实现TA量化值的范围的扩大，以使得用户设备可调整的TA范围能够适应存在中继设备的通信系统。
在一个示例中，该方法还包括：通过扩大该MAC RAR的大小，增加该TA量化值占用的比特。
参照图17所示的MAC RAR的示意图，可以将Timing Advance Command字段占用的比特数扩大至13或更多，并保持其他字段占据的比特数不变。采用本方案，通过增加MAC RAR占用的字节数，可以在不改变原有MAC RAR的结构的情况下，实现TA量化值的范围的扩大。
在另一个示例中，该方法还包括：保持该MAC RAR的大小不变，通过占用MAC RAR中的预留字段增加该TA量化值占用的比特。
参照图17所示的MAC RAR的示意图，可以将R字段并入Timing Advance Command字段，以实现预留字段的占用，进而增加TA量化值占用的比特。采用本方案，通过占用MAC RAR中的预留字段以增加TA量化值占用的比特，可以在保持原有MAC RAR的占用的总字节数的情况下，实现TA量化值的范围的扩大。
在又一些示例中，该TA量化值的取值范围为0至N3，其中，N3大于4096。
本领域技术人员应理解，TA量化值的取值范围与其所占用的比特数相关，例如，在TA量化值仅占用12比特时，能够表征的最大值即为4096，如果将TA量化值占用的比特数扩大至大于12时，则该TA量化值的最大值则可以大于4096。采用上述方案，在TA量化值占用的比特数大于12的情况下，该TA量化值能够的取值范围可以大于4096，以适应存在中继设备的通信系统，避免了因使用中继设备导致用户设备发送的信号无法实现上行同步的问题。

其中，该MAC CE可以是绝对定时提前指令MAC CE，该MAC CE中的TA量化值可以用于调整用户设备当前的传输定时的绝对量。
采用上述方案，通过将MAC CE的TA量化值占用的比特数提高至X2比特，使得该TA量化值相较于相关技术占用比特数更多，能够有效地实现TA量化值的范围的扩大，以实现用户设备可调整的TA范围能够适应存在中继设备的通信系统。
在一个示例中，该方法还包括：保持该MAC CE的大小不变，通过占用MAC CE中的预留字段增加该TA量化值占用的比特。
示例地，参照图19所示的相关技术中的绝对定时提前指令MAC CE的示意图，该MAC CE指令包括4个R字段，即预留字段，采用上述示例中的方案，则可以将4个预留字段中的任意一个或多个并入Timing Advance Command字段，以实现预留字段的占用，进而 增加TA量化值占用的比特。例如，若占用一个预留字段，则Timing Advance Command字段占用的比特数则可以加一，此时TA量化值占用的比特数X2＝13。采用本方案，通过占用MAC CE中的预留字段以增加TA量化值占用的比特，可以在保持原有MAC CE的占用的总字节数的情况下，实现TA量化值的范围的扩大。
在另一个示例中，该方法还包括：通过扩大该MAC CE的大小，增加该TA量化值占用的比特。
示例地，参照图19所示的MAC CE的示意图，可以将Timing Advance Command字段占用的比特数扩大至13，并保持其他字段占用的比特数。采用本方案，通过增加MAC CE占用的字节数，可以在不改变原有MAC CE的结构的情况下，实现TA量化值的范围的扩大。
在又一个示例中，该TA量化值的取值范围为0至N3，其中，N3大于4096。
本领域技术人员应理解，TA量化值的取值范围与其所占用的比特数相关，例如，在TA量化值仅占用12比特时，能够表征的最大值即为4096，如果将TA量化值占用的比特数扩大至大于12时，则该TA量化值的最大值则可以大于4096。采用上述方案，通过将TA量化值占用的比特数扩大至大于12，使得该TA量化值的取值范围可以大于4096，以适应存在中继设备的通信系统，避免了因使用中继设备导致用户设备发送的信号无法实现上行同步的问题。
图7是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图7所示，包括：
S701、基站确定第一传输时延和第二传输时延，该第一传输时延为用户设备与中继设备之间的传输时延，该第二传输时延为该中继设备与该基站之间的传输时延。
S702、基站根据该第一传输时延和该第二传输时延向该用户设备发送媒体接入控制层控制单元MAC CE，该MAC CE包括TA量化值，其中，该TA量化值占用X3比特，其中，X3大于6，该TA量化值是用于调整该用户设备当前的传输定时的相对量。
采用本方案，通过将MAC CE中用于调整用户设备当前的传输定时的相对量的TA量化值占用的比特数提高至X3比特，使得该TA量化值相较于相关技术占用比特数更多，能够有效地实现TA量化值的范围的扩大，以实现用户设备可调整的TA范围能够适应存在中继设备的通信系统。
示例地，参照图18所示的相关技术中的相对定时提前指令MAC CE的示意图，可以将该MAC CE中的Timing Advance Command字段占用的比特数增加至7或者更多。
在一个示例中，该TA量化值的取值范围为0至M，其中，M大于63。
本领域技术人员应理解，TA量化值的取值范围与其所占用的比特数相关，例如，在TA量化值仅占用6比特时，能够表征的最大值即为64，如果将TA量化值占用的比特数扩大至大于6时，则该TA量化值的最大值则可以大于64。采用上述方案，通过将TA量化值占用的比特数扩大至大于6比特，能够使得该TA量化值的取值范围可以大于63，以适应存在中继设备的通信系统，避免了因使用中继设备导致用户设备发送的信号无法实现上行同步的问题。

S802、基站向该用户设备发送该第一传输时延的量化值和该第二传输时延的量化值。
其中，第一传输时延的量化值以及第二传输时延的量化值可以是通过不同的信令发送的，例如第一传输时延的量化值是基于MAC RAR发送至用户设备的，第二传输时延的量 化值是基于MAC CE发送至用户设备的。或者，该第一传输时延的量化值以及第二传输时延的量化值也可以是通过同一信令发送的，例如，某一MAC RAR中可以包括第一传输时延的量化值，以及第二传输时延的量化值。示例地，在该信令的Timing Advance Command字段的前L个比特用于表征第一传输时延的量化值，其他比特用于表征第二传输时延的量化值，用户终端即可以基于该MAC RAR确定第一传输延时的量化值以及第二传输时延的量化值。其中，L小于该Timing Advance Command字段占用的比特数，该Timing Advance Command字段占用的比特数大于12。
此外，第一传输时延的量化值可以是用于调整用户设备的传输定时的绝对量，也可以是用于调整用户设备的传输定时的相对量。第二传输时延的量化值可以是用于调整用户设备的传输定时的绝对量，也可以是用于调整用户设备的传输定时的相对量。
并且，在第一传输延时的量化值是用于调整用户设备的传输定时的绝对量的情况下，该第一传输延时的量化值占用的比特数可以为12，也可以大于12。在第一传输延时的量化值是用于调整用户设备的传输定时的相对量的情况下，该第一传输延时的量化值占用的比特数可以为6，也可以大于6。在第二传输延时的量化值是用于调整用户设备的传输定时的绝对量的情况下，该第二传输延时的量化值占用的比特数可以为12，也可以大于12。在第二传输延时的量化值是用于调整用户设备的传输定时的相对量的情况下，该第二传输延时的量化值占用的比特数可以为6，也可以大于6。
用户终端基于第一传输时延的量化值以及第二传输时延的量化值的和值，即可以得到在对应的通信系统中的整体的TA量化值的大小，因此，基站通过第一传输时延的量化值以及第二传输时延的量化值，能够扩大用户终端用于调整传输定时的TA量化值的取值范围，以适应存在中继设备的通信系统，避免了因使用中继设备导致用户设备发送的信号无法实现上行同步的问题。

S903、通过第二TA信令向该用户设备发送该第二传输时延，该第二TA信令包括第二标识和该第二传输时延。
示例地，该第一TA信令以及第二TA信令可以均为相对定时提前指令MAC CE，参照图18，第一标识以及第二标识可以存储于信令中的TAG ID字段，例如，在基站发送的MAC CE中，TAG ID字段中的信息为00的情况下，则该TAG ID表征该MAC CE信令为第一TA信令，在该MAC CE信令中的Timing Advance Command字段表征的信息即为第一传输时延的量化值；TAG ID字段中的信息为01的情况下，则该TAG ID表征该MAC CE信令为第二TA信令，该MAC CE信令中的Timing Advance Command字段表征的信息即为第二传输时延的量化值。
或者，该第一TA信令以及第二TA信令也可以是MAC RAR，或者绝对定时提前指令MAC CE，具体的实施方案本公开在此不再赘述。
采用上述方案，通过在第一传输时延的第一TA信令以及第二传输时延对应的第二TA信令中添加第一标识以及第二标识，以使得用户设备能够根据该第一标识以及第二标识确定其接收到的信令对应的量化值是第一传输时延对应的量化值还是第二传输时延对应的量化值，进而更加准确地得到该用户终端在通信系统中整体的TA量化值，并更准确地对传输定时进行调整。

示例地，参照图17所示的MAC RAR的示意图，可以将Timing Advance Command字段占用的比特数扩大至13或更多至X1比特，并保持其他字段占据的比特数。通过增加MAC RAR占用的字节数，可以在不改变原有MAC RAR的结构的情况下，实现TA量化值的范围的扩大。
示例地，参照图17所示的MAC RAR的示意图，可以将R字段并入Timing Advance Command字段，以实现预留字段的占用，进而增加TA量化值占用的比特至X1比特。通 过占用MAC RAR中的预留字段以增加TA量化值占用的比特，可以在保持原有MAC RAR的占用的总字节数的情况下，实现TA量化值的范围的扩大。
在一个示例中，TA量化值的取值范围为0至N3，其中，N3大于4096。采用该方案，在TA量化值占用的比特数大于12的情况下，该TA量化值能够的取值范围可以大于4096，以适应存在中继设备的通信系统，避免了因使用中继设备导致用户设备发送的信号无法实现上行同步的问题。
图14是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图14所示，该方法包括：
S1401、用户设备从基站发送的媒体接入控制层控制单元MAC CE中获取TA量化值，其中，该TA量化值占用X2比特，其中，X2大于12。
S1402、用户设备根据该TA量化值调整传输定时。
其中，该MAC CE可以是绝对定时提前指令MAC CE，该MAC CE中的TA量化值是用于调整用户设备当前的传输定时的绝对量。即用户设备根据该TA量化量可以直接对用户设备当前的传输定时进行替换。例如，用户设备可以基于如下公式进行传输定时T TA的计算：
T TA＝(N TA+N TA,offset)*T c；
其中，N TA是该TA量化值，N TA,offset是基站发送的时间偏移量化值的和值，T c为预定义的时间单位。
采用上述方案，通过将MAC CE的TA量化值占用的比特数提高至X2比特，使得该TA量化值相较于相关技术占用比特数更多，能够有效地实现TA量化值的范围的扩大，以实现用户设备可调整的TA范围能够适应存在中继设备的通信系统。
示例地，参照图19所示的相关技术中的绝对定时提前指令MAC CE的示意图，该MAC CE指令包括4个R字段，即预留字段，则可以将4个预留字段中的任意一个或多个并入Timing Advance Command字段，以实现预留字段的占用，进而增加TA量化值占用的比特。例如，若占用一个预留字段，则Timing Advance Command字段占用的比特数则可以加一，此时TA量化值占用的比特数X2＝13。采用本方案，通过占用MAC CE中的预留字段以增加TA量化值占用的比特，可以在保持原有MAC CE的占用的总字节数的情况下，实现TA量化值的范围的扩大。
在一个示例中，TA量化值的取值范围为0至N3，其中，N3大于4096。
本领域技术人员应理解，TA量化值的取值范围与其所占用的比特数相关，例如，在TA量化值仅占用12比特时，能够表征的最大值即为4096，如果将TA量化值占用的比特数扩大至大于12时，则该TA量化值的最大值则可以大于4096。采用上述方案，通过将TA量化值占用的比特数扩大至大于12，使得该TA量化值的取值范围可以大于4096，以适应存在中继设备的通信系统，避免了因使用中继设备导致用户设备发送的信号无法实现上行同步的问题。
图15是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图15所示，该方法包括：
S1501、用户设备从基站发送的媒体接入控制层控制单元MAC CE中获取TA量化值，其中，该TA量化值占用X3比特，其中，X3大于6，该TA量化值的取值范围为0至M，其中，M大于63。
S1502、用户设备根据该TA量化值将传输定时调整为N TA_new。
其中，N TA_new＝N TA_old+(T A-x)*16*64/2 μ；
N TA_old为该用户设备在调整之前的传输定时，T A为该TA量化值，x＝(M-1)/2，子载波间隔为15*2 μ。
其中，该MAC CE为相对定时提前指令MAC CE，该MAC CE中的TA量化值是用于调整用户设备当前的传输定时的相对量。
通过将MAC CE中用于调整用户设备当前的传输定时的相对量的TA量化值占用的比特数提高至X3比特，使得该TA量化值相较于相关技术占用比特数更多，能够有效地实现TA量化值的范围的扩大，以实现用户设备可调整的TA范围能够适应存在中继设备的通信系统。
并且，本领域技术人员应理解，TA量化值的取值范围与其所占用的比特数相关，例如，在TA量化值仅占用6比特时，能够表征的最大值即为64，如果将TA量化值占用的比特数扩大至大于6时，则该TA量化值的最大值则可以大于或等于64。通过将TA量化值占用的比特数扩大至大于6比特，能够使得该TA量化值的取值可以大于63。
采用上述方案，通过获取基站发送的MAC CE并获取取值范围被扩大的TA量化值，并基于该TA量化值，按照上述公式对用户终端的传输定时进行调整，能够使得该用户终端能够在应用中继设备的场景下，仍可以准确地基于该传输定时实现信号的上行同步。
图16是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图16所示，该方法包括：
S1601、用户设备接收基站发送第一传输时延的量化值和第二传输时延的量化值。
S1602、用户设备根据该第一传输时延的量化值N TA#1和该第二传输时延的量化值N TA#2将传输定时调整为T TA。
其中，T TA＝(N TA#1+N TA#2+N TA,offset)*T c；
N TA,offset为该基站发送的时间偏移量化值，T c为预定义的时间单位。
其中，上述第一传输时延的量化值以及第二传输时延的量化值可以是基站发送的，并且，第一传输时延的量化值以及第二传输时延的量化值可以是通过不同的信令发送的，例如第一传输时延的量化值是基于MAC RAR通过第一TA信令发送至用户设备的，第二传输时延的量化值是基于MAC CE通过第二信令发送至用户设备的。或者，该第一传输时延的量化值以及第二传输时延的量化值也可以是通过同一信令发送的，即，该第一TA信令和第二TA信令可以是相同的信令。
例如，某一MAC RAR中可以包括第一传输时延的量化值，以及第二传输时延的量化值。示例地，在该信令的Timing Advance Command字段的前L个比特用于表征第一传输时延的量化值，其他比特用于表征第二传输时延的量化值，用户终端即可以基于该MAC RAR确定第一传输延时的量化值以及第二传输时延的量化值。其中，L小于该Timing Advance Command字段占用的比特数，该Timing Advance Command字段占用的比特数大于12。
采用上述方案，用户设备通过接受基站发送的用户设备与中继设备之间的第一传输时延的量化值，以及中继设备与基站之间第二传输时延的量化值，并基于上述公式，可以计算得到新的传输定时，并根据该传输定时进行调整，进而保证该用户设备基于调整后的传输定时发送的信号能够实现上行同步，确保了用户终端在包括中继设备的通信系统中能够有效的发送信号。
进一步，上述用户设备在接收到基站发送的信令之后，还可以根据信令中的标识，确定该信令为第一TA信令或者第二TA信令，其中第一TA信令包括第一传输时延，第二TA信令包括第二传输时延。用户设备基于第一TA信令，以及第二TA信令，即可以得到第一传输时延的TA量化值N TA#1，以及第二传输时延的TA量化值N TA#2。
