下面结合附图对本申请所提出的一种定时关系调整方法及其装置进行详细的介绍。
图2为本申请一实施例的一种定时关系调整方法的流程示意图，该方法应用于网络设备，如图2所示，该方法包括：
S10，向终端设备指示至少一个服务波束的时间偏移，其中，时间偏移用于对网络设备与终端设备之间的定时关系进行调整。
在第五代移动通信技术(fifth-generation，5G)新的无线技术(NewRadio，NR)中，使用高频进行信号传输时，其传输路径穿透损耗等较大，覆盖范围较小。为了提高覆盖范围，5G通信一般采用多个服务波束(beam)的传输方式提升信号强度。目前，基于单beam的传输方式即全向传输方式，可以同时覆盖整个方向，但各个方向的覆盖半径较小。基于多beam的传输方式的覆盖半径较大，但每个beam需要在不同的时间轮询，会带来一定的时延，即发生了一定的时长的时间偏移。本申请中，不并限制beam的传输方式，即服务波束可为一个或多个。
可选地，服务波束的时间偏移包括以下中的至少一项：
服务波束的偏移参数；
服务波束的偏移参数与基准偏移参数之间的偏移量；
基准偏移参数和服务波束的偏移参数与基准偏移参数之间的偏移量。
图3是一种网络设备侧上下行定时对齐传输数据的示意图，图4是一种网络设备侧上下行定时不对齐传输数据的示意图。如图3和图4所示，在网络设备侧上下行定时传输数据时，会发生上下行数据传输的时延，对于该时延，可以采用引入时间偏移来补偿传输时延，可选地，可以将该时间偏移记为Koffset(时间偏移参数)。为此，网络设备需要将补偿时间偏移的Koffset发送给终端设备，以便于终端设备基于时间偏移对网络设备与终端设备之间的定时关系进行调整。
可选地，终端设备基于时间偏移对网络设备与终端设备之间的定时关系进行调整可以应用在下行控制信息(Downlink Control Information，DCI)调度的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输；混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈信息的传输以及多址接入信道控制单元(Multiple Access Channel Control Element，MAC CE)的传输等。
本申请实施例提出了一种定时关系调整方法，通过向终端设备指示至少一个服务波束的时间偏移，其中，时间偏移用于对网络设备与终端设备之间的定时关系进行调整。本申请解决由于卫星高速移动带来的终端设备与网络设备间的定时关系调整的问题，保证在卫星通信场景下数据交互的可靠性。
图5为本申请一实施例的一种定时关系调整方法的流程示意图，该方法应用于网络设备，如图5所示，该方法包括：
S20，显式或隐式向终端设备指示至少一个服务波束的时间偏移。
本申请实施例提出的网络设备向终端设备指示服务波束的时间偏移包括两种形式，分别为显式指示和隐式指示。其中，服务波束可为一个或多个。其中，时间偏移用于对网络设备与终端设备之间的定时关系进行调整。其中，显式指示可以理解为网络设备通过消息直接向终端设备发送服务波束的时间偏移，即网络设备直接在消息中携带服务波束的时间偏移；隐式指示可以理解为网络设备通过其他参数指示服务波束的时间偏移，即网络设备并不直接将服务波束的时间偏移直接发送给终端设备。其他参数例如可以为频率或者RNTI等参数，其他参数与时间偏移之间存在映射关系，终端设备可以基于该映射关系获取到服务波束的时间偏移。
可选地，当网络设备采用显式指示向终端设备指示服务波束的时间偏移时，可通过群组共用下行控制信息向终端设备发送时间偏移集合。
可选地，当网络设备采用隐式指示向终端设备指示服务波束的时间偏移时，可通过随机接入响应向终端设备指示服务波束的时间偏移。
终端设备在确定服务波束的时间偏移之后，可以基于时间偏移对网络设备与终端设备之间的定时关系进行调整。
本申请实施例提出了一种定时关系调整方法，通过向终端设备指示至少一个服务波束的时间偏移，其中，时间偏移用于对网络设备与终端设备之间的定时关系进行调整。本申请解决由于卫星高速移动带来的终端设备与网络设备间的定时关系调整的问题，保证在卫星通信场景下数据交互的可靠性。

服务波束为多个时，不同的服务波束对应有不同的时间偏移。
以服务波束的时间偏移集合包括服务波束的偏移参数为例，即时间偏移集合可包括具体的时间偏移参数Koffset的值。比如说，时间偏移集合可记为{Koffset1，Koffset2，Koffset3…KoffsetN}。其中，Koffset1对应服务波束1的时间偏移参数，Koffset2对应服务波束2的时间偏移参数，KoffsetN对应服务波束N的时间偏移参数。
以服务波束的时间偏移集合包括服务波束的偏移参数与基准偏移参数之间的偏移量为例，设置一个基准偏移参数，将该基准偏移参数记为Koffset0，同时获取每个服务波束的时间偏移参数Koffset与基准偏移参数Koffset0的差值，将该差值作为每个服务波束的时间偏移参数Koffset与基准偏移参数Koffset0的偏移量。比如说，时间偏移集合可记为{偏移值1，偏移值2…偏移值N}。其中，偏移值1对应服务波束1的时间偏移参数Koffset与基准偏移参数Koffset0的偏移量，偏移值2对应服务波束2的时间偏移参数Koffset与基准偏移参数Koffset0的偏移量，偏移值N对应服务波束N的时间偏移参数Koffset与基准偏移参数Koffset0的偏移量。
以服务波束的时间偏移集合包括基准偏移参数和服务波束的偏移参数与基准偏移参数之间的偏移量为例，设置一个基准偏移参数，将该基准偏移参数记为Koffset0，同时获取每个服务波束的时间偏移Koffset与基准偏移参数Koffset0的差值，将该差值作为每个服务波束的时间偏移Koffset与基准偏移参数Koffset0的偏移量。比如说，时间偏移集合可记为{Koffset0，偏移值1，偏移值2…偏移值N}。其中，Koffset0为预先设置的基准偏移参数，偏移值1对应服务波束1的时间偏移参数Koffset与基准偏移参数Koffset0的偏移量，偏移值2对应服务波束2的时间偏移参数Koffset与基准偏移参数Koffset0的偏移量，偏移值N对应服务波束N的时间偏移参数Koffset与基准偏移参数Koffset0的偏移量。
