Description

无线通信的方法、终端设备和网络设备 技术领域

背景技术
在新无线(New Radio，NR)系统中，终端设备按照一定时序关系进行传输，例如，若终端设备在时隙n上收到第一下行传输，第一下行传输可以关联时隙n+K上的第一上行传输。
为了克服非地面通信网络(Non-Terrestrial Networks，NTN)系统中的大传输时延，在NTN系统中引入偏移参数K offset，并将该K offset参数应用到相关的时序关系中。具体地，对于初始接入过程的终端设备，使用小区专用时序偏移值(cell specific K_offset)确定用于上行传输的时序关系。初始接入完成后，终端设备需要根据终端设备专用时序偏移值(UE specific K_offset)确定用于上行传输的时序关系。由于在NTN系统中，网络设备是移动的，可能存在UE specific K_offset和cell specific K_offset不同的情况，此情况下，如何配置UE specific K_offset以保证终端设备正常工作是一项亟需解决的问题

具体地，可以将图2至图3中的卫星替换为UAS平台。例如，UAS平台包括但不限于高空平台站(High Altitude Platform Station，HAPS)。
为便于理解本申请实施例，下面对NTN系统中与小区覆盖范围相关的内容进行说明。
图4是本申请实施例提供的NTN系统下的小区覆盖范围的示意图。
如图4所示，卫星(或UAS平台)的视野取决于天线图和最小仰角，卫星(或UAS平台)在其视野范围内针对给定服务区域生成多个波束，其中每一个波束的覆盖范围可以称为小区覆盖范围且波束通常为椭圆形。
需要说明的是，为便于说明，图4仅示出了一个波束的覆盖范围，在其他可替代实施例中，可以由多个波束形成多个小区，本申请对此不作具体限定。除非特别说明，在下文实施例中，网络设备的覆盖范围可以指卫星的所有波束的覆盖范围。
LEO卫星小区场景可以包括地球移动小区(Earth moving cells)场景和地球固定小区(Earth fixed cells)场景，其中，Earth moving cells场景是指随着卫星移动，小区也随着移动，卫星和小区之间的相对位置保持不变。Earth fixed cells场景是指随着卫星移动，小区在地面上的位置是固定的，但是，由于卫星是高速运动的，因此，卫星覆盖的该固定小区的大小或角度会发生变化。
与传统NR采用的蜂窝网络相比，NTN中终端设备与卫星之间的定时提前(timing advance，TA)调整量更大。因此，需要引入时序偏移值以增强上下行时序关系，避免时序关系混乱。例如，假设网 络设备调度终端设备在时隙n发送上行数据，此时，终端设备需要增强到时隙n+Koffset上发送上行数据，以避免终端设备的上行发送发生在下行调度之前。其中，Koffset为增强的时序偏移值，且Koffset大于或等于终端设备的TA。
例如，对于初始接入过程的终端设备，由于网络设备缺少该终端设备的相关信息，因此可以通过系统消息配置一个小区专用时序偏移值(cell specific K_offset)。初始接入完成后，终端设备需要根据终端设备专用时序偏移值(UE specific K_offset)确定用于上行传输的时序关系。由于在NTN场景中，网络设备是移动的，可能存在某一时刻的UE specific K_offset大于当前的cell specific K_offset的情况，进而导致终端设备失去连接而不能正常工作，因此，如何配置合适的小区专用时序偏移值以保证终端设备的正常工作是一项亟需解决的问题。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图5是根据本申请实施例的无线通信的方法200的示意性流程图，如图5所示，该方法200包括如下内容：
S210，终端设备接收网络设备的第一指示信息和第二指示信息，其中，所述第一指示信息用于指示目标小区专用时序偏移值，所述第二指示信息用于指示差分终端设备专用时序偏移值；
S220，所述终端设备根据所述目标小区专用时序偏移值和所述差分终端设备专用时序偏移值，确定目标终端设备专用时序偏移值。
在一些实施例中，该方法200可以应用于NTN系统，例如LEO卫星小区场景，或者，网络设备和终端设备之间的RTT较大的其他场景。也即，网络设备可以为NTN系统中的网络设备，例如卫星。
在一些实施例中，第一指示信息是通过系统消息或MAC CE发送的。
在一些实施例中，第二指示信息是通过MAC CE发送的。
可选地，差分终端设备专用时序偏移值(记为differential UE specific K_offset)可以是网络设备根据小区专用时序偏移值(记为cell specific K_offset)和当前时刻的终端设备专用时序偏移值(记为UE specific K_offset)确定的。例如，differential UE specific K_offset为cell specific K_offset减去UE specific K_offset的差值。
在一些实施例中，该终端设备根据目标小区专用时序偏移值和差分终端设备专用时序偏移值，确定目标终端设备专用时序偏移值，可以包括：
将目标小区专用时序偏移值和差分终端设备专用时序偏移值的差值确定为目标终端设备专用时序偏移值。即UE specific K_offset＝cell specific K_offset-differential UE specific K_offset。
因此，在本申请实施例中，连接态的终端设备可以根据目标小区专用时序偏移值和差分终端设备专用时序偏移值，确定目标终端设备专用时序偏移值，进一步基于该目标终端设备专用时序偏移值进行上行传输，有利于保证终端设备和网络设备之间的时序关系。
为降低网络设备指示differential UE specific K_offset的复杂度，定义differential UE specific K_offset的取值为大于或等于0的值。但是，一些场景中，网络设备是移动的，例如Earth fixed cells场景，可能存在某一时刻的UE specific K_offset大于当前的cell specific K_offset的情况，此情况下，根据上述差分方式网络设备无法给终端设备配置一个正确的UE specific K_offset，基于该技术问题，在本申请实施例中，进一步对目标小区专用时序偏移值的配置进行了设计以保证网络设备基于差分方式能够给终端设备配置一个正确的UE specific K_offset，保证终端设备的正常工作。
在本申请一些实施例中，目标小区专用时序偏移值可以根据以下中的至少一项确定：
第一取值范围，该第一取值范围为小区专用时序偏移值可配置的取值范围；
网络设备的运动位置；
网络设备的覆盖范围；
所述网络设备的运行时间信息。
也即，目标小区专用时序偏移值可以是周期性更新的，或者，基于运动轨迹更新的，或者，基于覆盖范围更新的。
基于上述信息确定给终端设备配置的目标小区专用时序偏移值有利于保证给终端设备配置的cell specific K_offset在一段运行轨迹，或者一定的覆盖范围，或者一段时间内是最大的cell specific K_offset，即UE specific K_offset小于或等于该cell specific K_offset，这样，基于差分方式，网络设备可以得到一个非负的differential UE specific K_offset。
应理解，在本申请实施例中，网络设备在不同的运行位置可能对应不同的覆盖范围，或者说，对应不同的小区。例如，对于Earth moving cells场景，随着卫星移动，小区也随着移动，又例如，对于 Earth fixed cells场景，随着卫星移动，小区在地面上的位置是固定的，但是，卫星和小区之间的角度会发生变化。
可选地，在一些实施例中，网络设备的运行时间信息可以指绝对时间信息，例如当前时刻，或者，也可以指相对时间信息，例如当前时刻在网络设备的一个运行周期中的相对时间信息。例如，该网络设备的运行时间信息可以指24小时中的某个时刻。又例如，一个运行周期是8小时，该网络设备的运行时间信息可以指当前时刻在8小时中的相对时间。
以下，结合具体实施例，说明目标小区专用时序偏移值的确定方式。
实施例1：目标小区专用时序偏移值根据第一取值范围确定。
在该实施例一中，小区专用时序偏移值对应一个可选的取值范围，即第一取值范围。
在一些实施例中，目标小区专用时序偏移值是第一取值范围中的最大的小区专用时序偏移值。
通过配置目标小区专用时序偏移值为第一取值范围中的最大值，有利于保证无论网络设备运行到哪个位置，cell specific K_offset均大于UE specific K_offset，即differential UE specific K_offset为正值，从而能够可以根据差分方式获得合理的UE specific K_offset，以保证终端设备的正常工作。
在一些实施例中，第一取值范围是预定义的，或者是网络设备配置的。
例如，如图6所示，第一取值范围是0～1023ms，此情况下，网络设备可以配置目标小区专用时序偏移值为1023ms。
在一些实施例中，第一取值范围与应用场景相关。例如，在GEO场景，该第一取值范围可以为[239]–[542]ms，在MEO场景，该第一取值范围可以为[47]–[395]ms，在LEO场景，该第一取值范围可以为[4]–[49]ms等，或者，所有场景采用相同的取值范围，例如均采用[0]–[542]ms或[0]–[1023]ms的取值范围。
在一些实施例中，第一取值范围的最大值可以是根据网络设备和终端设备之间的最大往返时延(Round Trip Time，RTT)和最小RTT确定。例如，根据网络设备的运行轨迹和小区中的终端设备之间的最大RTT和最小RTT的差值确定。
作为示例而非限定，网络设备和终端设备之间的最大RTT可以为服务链路和馈电链路在仰角等于10度时的RTT，网络设备和终端设备之间的最小RTT可以为服务链路和馈电链路在仰角等于90度时的RTT。
在另一些实施例中，第一取值范围的最大值可以是根据网络设备的运行轨迹和小区中的终端设备之间的最大RTT确定。例如，根据网络设备的运行轨迹和小区的中心位置的终端设备之间的最大RTT确定，或者根据网络设备的运行轨迹和小区的边缘位置的终端设备之间的最大RTT确定。
采用此方式配置目标小区专用时序偏移值的鲁棒性较强，网络设备只需在初始接入阶段进行目标小区专用时序偏移值的配置，不必随着网络设备的运动轨迹或覆盖范围等更新目标小区专用时序偏移值，有利于降低网络设备实现的复杂度，同时降低信令开销。
实施例2：目标小区专用时序偏移值是根据网络设备的运行位置确定的。
由于网络设备的运行轨迹是椭圆形，网络设备在不同的运行位置与小区内的终端设备之间的RTT会有差异，因此，所适用的小区专用时序偏移值也会有差异。因此，网络设备可以基于运行位置，给网络设备配置合适的小区专用时序偏移值。
在一些实施例中，网络设备可以根据运行位置对应的目标运行轨迹分段确定目标小区专用时序偏移值。
例如，可以将网络设备的运行轨迹划分为多个运行轨迹分段，每个运行轨迹分段对应相应的最大小区专用时序偏移值。这样，网络设备可以根据其运行位置对应的运行轨迹分段确定给终端设备配置的目标小区专用时序偏移值。
具体而言，由于网络设备的运行轨迹是已知的，将网络设备的运行轨迹进行分段，进一步确定每个运行轨迹分段对应的最大小区专用时序偏移值，这样，网络设备可以基于运行轨迹分段进行小区专用时序偏移值的更新。
在一些实施例中，每个运行轨迹分段对应的最大小区专用时序偏移值可以是根据该运行轨迹分段中的每个运行位置和网络设备在该运行位置对应的覆盖范围内的终端设备之间的最大RTT确定的。
应理解，该网络设备在该运行位置对应的覆盖范围可以指网络设备在该运行位置对应的小区。
例如，可以根据运行轨迹分段中的所有运行位置和对应覆盖范围内的终端设备之间的最大RTT中的最大值确定该运行轨迹分段对应的最大小区专用时序偏移值。
或者，根据运行轨迹分段中的每个运行位置对应的最大小区专用时序偏移值确定。例如，可以将该运行轨迹分段中的所有运行位置对应的最大小区专用时序偏移值中的最大值确定为该运行轨迹分段对应的最大小区专用时序偏移值。
可选地，网络设备在该运行位置对应的覆盖范围内的终端设备可以是小区的中心位置的终端设备，或者，也可以是小区的边缘位置的终端设备，例如小区内距离该运行位置最远的位置上的终端设备。
作为示例，一个运行轨迹分段包括n个运行位置，每个运行位置对应一个覆盖范围，运行位置k对应覆盖范围k，其中，k＝1,2,……,n，网络设备可以确定该n个运行位置中的每个运行位置和对应的覆盖范围内的终端设备之间的最大RTT。
例如，在网络设备处于运行位置1时，若覆盖范围1内的位置1处的终端设备和网络设备之间的RTT最大，则该运行位置1对应的最大小区专用时序偏移值根据该位置1处的终端设备和运行位置1的网络设备之间的RTT确定，其他运行位置对应的最大小区专用时序偏移值的确定方式类似，进一步可以将所有运行位置对应的最大小区专用时序偏移值中的最大值确定为该运行轨迹分段对应的最大小区专用时序偏移值。或者，网络设备可以确定在n个运行位置中的每个运行位置时，终端设备和网络设备之间的最大RTT，进一步基于该每个运行位置对应的最大RTT中的最大值，确定该运行轨迹分段对应的最大小区专用时序偏移值。
因此，当网络设备运行到某个运行轨迹分段时，由于该运行轨迹分段对应的最大小区专用时序偏移值是根据该运行轨迹分段中的网络设备和终端设备之间的最大RTT确定的，有利于保证无论网络设备运行到该运行轨迹分段中的哪个位置，cell specific K_offset均大于UE specific K_offset，即differential UE specific K_offset为正值，从而能够根据差分方式获得一个合理的UE specific K_offset，以保证终端设备的正常工作。
如图7所示，网络设备在t0到t1的运行轨迹对应第一运行轨迹分段，在t1到t2的运行轨迹对应第二运行轨迹分段，其中，第一运行轨迹分段和第二运行轨迹分段分别对应一个最大小区专用时序偏移值。
其中，第一运行轨迹分段对应的最大小区专用时序偏移值可以根据网络设备第一运行轨迹分段中的每个运行位置和对应覆盖区域中的终端设备之间的RTT确定，或者说，根据第一运行轨迹分段中的每个运行位置对应的最大小区专用时序偏移值确定。第二运行轨迹分段对应的最大小区专用时序偏移值可以根据网络设备第二运行轨迹分段中的每个运行位置和对应覆盖区域中的终端设备之间的最大RTT确定，或者说，根据第二运行轨迹分段中的每个运行位置对应的最大小区专用时序偏移值确定。
假设网络设备在t0的运行位置对应的最大小区专用时序偏移值是cell specific K_offset 1，在t1的运行位置对应的最大小区专用时序偏移值是cell specific K_offset 2，其中，cell specific K_offset 2大于cell specific K_offset 1，则可以确定cell specific K_offset 2为第一运行轨迹分段对应的最大小区专用时序偏移值。假设网络设备在t2的运行位置对应的最大小区专用时序偏移值是cell specific K_offset 3，其中，cell specific K_offset 3大于cell specific K_offset 2，则可以确定cell specific K_offset 3为第二运行轨迹分段对应的最大小区专用时序偏移值。
因此，当网络设备在运行到第一运行轨迹分段时，给终端设备配置的目标小区专用时序偏移值为cell specific K_offset 2，当网络设备在运行到第二运行轨迹分段时，给终端设备配置的目标小区专用时序偏移值为cell specific K_offset 3，即网络设备运行到某个运行轨迹分段中时，给终端设备配置的小区专用时序偏移值是该运行轨迹分段对应的最大小区专用时序偏移值，有利于保证无论网络设备运行到该运行轨迹分段中的哪个位置，cell specific K_offset均大于UE specific K_offset，即differential UE specific K_offset为正值，从而能够保证根据差分方式获得一个合理的UE specific K_offset，以保证终端设备的正常工作。
因此，在本申请实施例中，网络设备可以基于运行轨迹更新小区专用时序偏移值。例如，网络设备在运行到下一个运行轨迹分段时，将小区专用时序偏移值更新为该运行轨迹分段所对应的最大小区专用时序偏移值。
实施例3：目标小区专用时序偏移值是根据网络设备的覆盖范围确定的。
在一些实施例中，网络设备的运行轨迹可以对应多个覆盖范围，每个覆盖范围对应一个最大小区专用时序偏移值。
在一些场景中，在网络设备运行时，网络设备的覆盖范围可能会随着网络设备的移动而发生变化，因此，网络设备和终端设备之间的RTT也可能发生变化，因此，可以基于网络设备的覆盖范围，给终端设备配置合适的小区专用时序偏移值。
在一些实施例中，网络设备在一段运行轨迹内对应的覆盖范围内可以认为是不变的，或者，在一段时间内对应的覆盖范围可以认为是不变的。
在一些实施例中，可以根据网络设备和其覆盖范围内的终端设备之间的最大RTT确定目标小区 专用时序偏移值。
具体地，由于网络设备的运行轨迹是已知的，因此网络设备在运行轨迹中对应的覆盖范围也是已知的，因此，可以根据网络设备和该网络设备的覆盖范围内的终端设备之间的最大RTT确定每个覆盖范围对应的最大小区专用时序偏移值。
可选地，网络设备的覆盖范围内的终端设备可以是小区的中心位置的终端设备，或者，也可以是小区的边缘位置的终端设备，例如小区内距离该运行位置最远的位置上的终端设备。
因此，在本申请实施例中，当网络设备的覆盖范围发生更新时，网络设备配置该更新后的覆盖范围对应的最大小区专用时序偏移值，有利于保证更新后的覆盖范围内的cell specific K_offset大于UE specific K_offset，即differential UE specific K_offset为正值，从而能够根据差分方式获得一个合理的UE specific K_offset，以保证终端设备的正常工作。
如图8所示，网络设备的覆盖范围为覆盖范围1时，可以配置目标小区专用时序偏移值为该覆盖范围1对应的最大小区专用时序偏移值。
其中，覆盖范围1对应的最大小区专用时序偏移值可以根据网络设备和该覆盖范围1中的终端设备之间的RTT确定。例如，可以根据网络设备和该覆盖范围1内的终端设备之间的最大RTT确定。
假设网络设备和覆盖范围1内的位置1处的终端设备之间的RTT对应cell specific K_offset 1，网络设备和覆盖范围内的位置2处的终端设备之间的RTT对应cell specific K_offset 2，……，网络设备和覆盖范围内的位置n处的终端设备之间的RTT对应cell specific K_offset n，若cell specific K_offset n是上述cell specific K_offset中的最大值，即网络设备和覆盖范围内的位置n处的终端设备之间的RTT最大，则可以确定该覆盖范围1对应的最大小区专用时序偏移值为cell specific K_offset n。
因此，当网络设备的覆盖范围为覆盖范围1时，给终端设备配置的目标小区专用时序偏移值为cell specific K_offset n，有利于保证cell specific K_offset均大于UE specific K_offset，即differential UE specific K_offset为正值，从而能够根据差分方式获得一个合理的UE specific K_offset，保证终端设备的正常工作。
因此，在本申请实施例中，网络设备可以基于覆盖范围更新小区专用时序偏移值，例如，覆盖范围发生变更时，将目标小区专用时序偏移值更新为变更后的覆盖范围所对应的最大小区专用时序偏移值。
实施例4：目标小区专用时序偏移值是根据所述网络设备的运行时间信息确定的。
由于网络设备的运行轨迹是已知的，网络设备在不同的时间点的运行位置，或者覆盖范围是已知的。即根据该网络设备的运行时间信息可以确定该网络设备的运行位置，或覆盖范围。因此，网络设备可以基于运行时间信息给终端设备配置合适的小区专用时序偏移值配置。
在一些实施例中，网络设备可以根据网络设备的运行时间信息对应的时间段确定目标小区专用时序偏移值。
例如，可以将网络设备的一个运行周期(例如绕地球运行一周所花费的时间)划分为多个时间段，每个时间段对应一个相应的最大小区专用时序偏移值。这样，网络设备可以根据网络设备当前的运行时间信息在一个运行周期中所对应的时间段确定给终端设备配置的目标小区专用时序偏移值。
在一些实施例中，该时间段可以和实施例2中的运行轨迹分段对应，或者，和实施例3中的覆盖范围对应。即在不同的时间段内，可以认为网络设备运行在不同的运行轨迹分段，或者，对应不同的覆盖范围。
在一些实施例中，每个时间段对应的最大小区专用时序偏移值根据所述网络设备在该时间段对应的覆盖范围内的终端设备和该网络设备之间的最大RTT确定。
例如，每个时间段对应的最大小区专用时序偏移值可以是根据该时间段内的每个运行位置和网络设备在该运行位置对应的覆盖范围内的终端设备之间的最大RTT确定的。
作为示例，可以根据时间段内的所有运行位置和对应覆盖范围内的终端设备之间的最大RTT中的最大值确定该时间段对应的最大小区专用时序偏移值。
在另一些实施例中，每个时间段对应的最大小区专用时序偏移值根据该时间段内的每个运行位置对应的最大小区专用时序偏移值确定。例如，可以将该时间段内的所有运行位置对应的最大小区专用时序偏移值中的最大值确定为该时间段对应的最大小区专用时序偏移值。
可选地，网络设备在该运行位置对应的覆盖范围内的终端设备可以是小区的中心位置的终端设备，或者，也可以是小区的边缘位置的终端设备，例如小区内距离该运行位置最远的位置上的终端设备。
如图9所示，假设t0～t1的时间段对应的最大小区专用时序偏移值为cell specific K_offset 2，其中，cell specific K_offset 2是这一段时间内对应的最大的小区专用时序偏移值，t1～t2的时间段对应的最大 小区专用时序偏移值为cell specific K_offset 3，其中，cell specific K_offset 3是这一段时间内对应的最大的小区专用时序偏移值。
那么在t0～t1的时间段，网络设备给终端设备配置的目标小区专用时序偏移值为cell specific K_offset 2，在t1～t2的时间段，网络设备给终端设备配置的目标小区专用时序偏移值为cell specific K_offset 3，这样可以保证在一段时间内，cell specific K_offset均大于UE specific K_offset，从而能够根据差分方式获得一个合理的UE specific K_offset，以保证终端设备的正常工作。
因此，在本申请实施例中，网络设备可以周期性地更新小区专用时序偏移值，例如，到达下一个时间段时，将目标小区专用时序偏移值更新为下一个时间段所对应的最大小区专用时序偏移值。
综上所述，在本申请实施例中，目标小区专用时序偏移值可以是周期性更新的，例如，到达下一个时间段时，将目标小区专用时序偏移值更新为该下一个时间段所对应的最大小区专用时序偏移值，或者，目标小区专用时序偏移值也可以是基于运行轨迹更新的，例如，当网络设备运行至下一个运行轨迹分段时，将目标小区专用时序偏移值更新为下一个运行轨迹分段对应的最大小区专用时序偏移值，或者，目标小区专用时序偏移值也可以是基于覆盖范围更新的，例如，当网络设备的覆盖范围变更时，将目标小区专用时序偏移值更新为变更后的覆盖范围对应的最大小区专用时序偏移值。
在本申请一些实施例中，第一指示信息是基于事件触发发送的。即目标小区专用时序偏移值可以是基于事件触发更新的。
在一些实施例中，该事件可以指导致小区专用时序偏移值需要更新的任意事件，例如，网络设备运行至另一个运行轨迹分段，或者，网络设备的覆盖范围变更，或者，运行至进入下一个时间段等。
在一些实施例中，该第一指示信息可以是在差分终端设备专用时序偏移值满足第一条件的情况下发送的。差分终端设备专用时序偏移值满足第一条件可以认为当前的UE specific K_offset较大(或者，随着网络设备的运行会越来越大，或者说，UE specific K_offset进入增大的趋势)，需要增大cell specific K_offset，以保证cell specific K_offset大于UE specific K_offset，即differential UE specific K_offset为正值。
在一些实施例中，第一指示信息是在differential UE specific K_offset大于或等于第一阈值的情况下发送的。differential UE specific K_offset大于或等于第一阈值时，随着网络设备的移动，可以认为UE specific K_offset会随着增大(即UE specific K_offset进入增大的趋势)，此情况下，将cell specific K_offset更新为更大的值，有利于保证cell specific K_offset大于UE specific K_offset，即differential UE specific K_offset为正值。
在一些实施例中，第一阈值是预定义的，或者是网络设备配置的。
在一些实施例中，第一阈值是第二取值范围的最大值，所述第二取值范围是差分终端设备专用时序偏移值可配置的取值范围。
例如，第二取值范围为0～63ms，则第一阈值可以为63ms。
在一些实施例中，第二取值范围是预定义的，或者是网络设备配置的。
在一些实施例中，第一指示信息是在小区专用时序偏移值和参考小区专用时序偏移值(记为reference cell specific K_offset)的差值大于或等于第二阈值的情况下发送的。
可选地，参考小区专用时序偏移值根据网络设备的覆盖范围内的参考点和网络设备之间的往返时延确定。
可选地，如图10所示，该参考点可以是小区的中心点，或者，也可以是小区中距离网络设备最近的点，或者小区中距离网络设备最远的点。
在一些实施例中，reference cell specific K_offset和cell specific K_offset的差值大于或等于第二阈值时，随着网络设备的移动，可以认为UE specific K_offset会随着增大(即UE specific K_offset进入增大的趋势)，此情况下，将cell specific K_offset更新为更大的值，有利于保证cell specific K_offset大于UE specific K_offset，即differential UE specific K_offset为正值。
应理解，在本申请实施例中，在基于事件触发确定发送第一指示信息时，第一指示信息所指示的目标小区专用时序偏移值可以根据前述实施例1至实施例4所述方式确定，或者，也可以是比当前使用的小区专用时序偏移值更大的一个时序偏移值，本申请对此不作限定。
综上所述，网络设备通过将cell specific K_offset配置为cell specific K_offset可配置范围内的最大值，或者，根据网络设备的运行轨迹，覆盖范围或时间信息给终端设备配置cell specific K_offset，有利于保证给终端设备配置合理的cell specific K_offset，进而保证UE specific K_offset小于cell specific K_offset，即differential UE specific K_offset为正值，从而保证根据差分方式获得一个合理的UE specific K_offset，保证终端设备的正常工作。
