Description

一种信息更新方法、装置、用户设备、基站及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种信息更新方法、装置、用户设备、基站及存储介质。
背景技术
在卫星通信系统中，通常会引入小区特定偏移值(cell-specific offset)和UE(User Equipment，终端设备)特定偏移值(UE-specific offset)来补偿传输时延。
相关技术中，该小区特定偏移值会随着卫星移动发生更新，由此基站通常会通过向UE发送更新后的系统信息来向UE指示更新后的小区特定偏移值。
但是，相关技术中，处于同一小区内的各个UE与基站之间的距离不同，从而使得各个UE对于基站发送的更新后的系统信息的接收时间也不相同。也即是，各个UE获取到更新后的小区特定偏移值的时间不同。此时，会使得基站进入一模糊期，在该模糊期内，对于基站而言，其与不同UE进行通信时，不同UE所使用的小区特定偏移值不同(即基站不明确UE所使用的是哪个小区特定偏移值)，则会影响通信的可靠性。

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实施例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、本公开实施例的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”及“若”可以被解释成为“在……时”或“当……时”或“响应于确定”。
图1a为本公开实施例提供的一种相关技术的信息更新方法中UE与基站之间的通信示意图，如图1a所示，小区内距离基站较近的近端UE会先接收到基站发送的更新后的系统信息，小区内距离基站较远的远端UE会后接收到基站发送的更新后的系统信息。其中，基于各个UE接收到更新后的系统信息的时间点不同，则会使得基站存在一模糊期，在该模糊期内：近端UE已经获取到更新后的小区特定偏移值，并使用该更新后的小区特定偏移值与基站进行通信，远端UE还未获取到更新后的小区特定偏移值，而是使用更新前的小区特定偏移值与基站进行通信，则会导致通信可靠性较低。基于此，本发明提出了一种信息更新方法、装置、用户设备、基站及存储介质，以解决相关技术中的信息更新方法易导致通信可靠性较低的技术问题。
下面参考附图对本公开一个实施例所提供的信息更新方法、装置、用户设备、基站及存储介质进行详细描述。
图1b为本公开一个实施例所提供的一种信息更新方法的流程示意图，该方法由支持卫星通信的UE执行，如图1b所示，该信息更新方法可以包括以下步骤：
步骤101、接收基站发送的更新后的小区特定偏移值。
在本公开的一个实施例之中，该基站可以是支持卫星通信的基站，该UE可以是指向用户提供语音和/或数据连通性的设备。终端设备可以经RAN(Radio Access Network，无线接入网)与一个或多个核心网进行通信，UE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(remoteterminal)、接入终端(access terminal)、用户装置(user terminal)或用户代理(useragent)。或者，UE也可以是无人飞行器的设备。或者，UE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终端。或者，UE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。
其中，在本公开的一个实施例之中，基站会通过系统信息向UE发送小区特定偏移值，具体可以将小区特定偏移值包含于系统信息中。以及，需要说明的是，基站通过系统信息向UE发送了一小区特定偏移值之后，若基站所处的卫星通信场景中的卫星相对于小区发生了移动，则基站需要更新小区特定偏移值，并需要通过更新后的系统信息向UE发送更新后的小区特定偏移值。
基于此，基站可以基于UE和基站所处的卫星通信场景来确定是否指示UE更新小区特定偏移值。
具体而言，在本公开的一个实施例之中，基站会基于星历信息确定基站和UE所处的卫星通信场景，其中，若基站确定出UE和基站所处的卫星通信场景为GEO(Geostationary Earth Orbit，静止地球轨道) 场景，则说明卫星相对于地静止，此时基站不需要指示UE进行小区特定偏移值的更新，即基站不向UE发送更新后的小区特定偏移值。当基站确定出UE和基站所处的卫星通信场景为NGSO(Non-GeoStationary Orbit，非对地静止轨道)场景时，则说明卫星相对于地会发生移动，此时，若卫星相对于地发生了移动，则基站需要通过更新后的系统信息向UE发送更新后的小区特定偏移值。
步骤102、接收基站发送的用于指示时间偏移值和/或时间窗口的配置信息。
其中，在本公开的一个实施例之中，该时间偏移值可以用于指示更新后的小区特定偏移值的延迟生效时间，时间窗口可以用于指示更新后的小区特定偏移值无效时间。以及，关于时间偏移值和时间窗口的详细介绍会在后续实施例进行描述。
进一步地，在本公开的一个实施例之中，UE接收基站发送的用于指示时间偏移值和/或时间窗口的配置信息的方法可以包括以下至少一种：
接收基站通过用户设备特定(UE-specific)信令发送的配置信息；
接收所述基站通过公共(common)信令发送的配置信息。
步骤103、基于时间偏移值和/或时间窗口使用更新后的小区特定偏移值。
其中，关于步骤103的详细介绍会在后续实施例描述。
此外，需要说明的是，在本公开的一个实施例之中，上述步骤101-步骤103的执行顺序仅为本公开示例的一种执行顺序，并不是固定的先后顺序。例如，在本公开的一个实施例之中，上述的步骤101和步骤102之间并不存在固定先后顺序，其中，可以先执行步骤101，再执行步骤102，也可以先执行步骤102，在执行步骤101。
综上所述，在本公开一个实施例所提供的信息更新方法之中，UE会接收基站发送的用于指示时间偏移值和/或时间窗口的配置信息，其中，该时间偏移值用于指示更新后的小区特定偏移值的延迟生效时间，时间窗口用于指示更新后的小区特定偏移值的无效时间。当UE接收到基站发送的更新后的小区特定偏移值时，会基于该时间偏移值和/或时间窗口来使用该更新后的小区特定偏移值。由此可知，本公开实施例之中，具体是通过时间偏移值和/或时间窗口来确定更新后的小区特定偏移值的生效时间，以确保小区内各个UE基于更新后的小区特定偏移值向基站发送上行信息时，基站对于不同UE使用的小区特定偏移值有相同的理解，保证通信的可靠性。
图2a为本公开一个实施例所提供的一种信息更新方法的流程示意图，该方法由支持卫星通信的UE执行，如图2a所示，该信息更新方法可以包括以下步骤：
步骤201、接收基站发送的更新后的小区特定偏移值。
其中，关于步骤201的相关介绍可以参考上述实施例描述，本公开实施例在此不做赘述。
步骤202、接收基站发送的用于指示时间偏移值的配置信息。
在本公开的一个实施例之中，该时间偏移值可以用于指示更新后的小区特定偏移值的延迟生效时间。
其中，在本公开的一个实施例之中，该时间偏移值可以是基站基于其覆盖范围内信号传输的RTT(Round Trip Time，往返时延)确定的。并且，在本公开的一个实施例之中，小区内不同的UE对应的时间偏移值会有所不同。以及，在本公开的一个实施例之中，该时间偏移值的大小可以与UE和基站之间的距离成反比。例如，距离基站越远的UE对应的时间偏移值越小，距离基站越近的UE对应的时间偏移值越大。
进一步地，在本公开的一个实施例之中，该时间偏移值可以为一固定值。在本公开的另一个实施例之中，该时间偏移值可以为一可配置值。
步骤203、基于时间偏移值使用更新后的小区特定偏移值。
其中，在本公开的一个实施例之中，基于时间偏移值使用更新后的小区特定偏移值的方法可以包括：接收到更新后的小区特定偏移值之后，在该时间偏移值之内使用更新前的小区特定偏移值与基站进行通信，且/或，在延迟了该时间偏移值之后，使用更新后的小区特定偏移值与基站进行通信。
需要说明的是，在本公开的一个实施例之中，该时间偏移值应当满足以下条件：该时间偏移值使得基站对于小区内各个UE所使用的小区特定偏移值有相同的理解。即，小区内的各个UE在延迟了对应的时间偏移值之后使用更新后的小区特定偏移值与基站进行通信时，对于基站而言不存在模糊期，该模 糊期为：由于小区内各个UE与基站之间的距离差异等原因导致各个UE接收到更新后的小区特定偏移值的时间点不同，从而对于基站而言所存在一段时期，在该时期内，小区内的不同UE与基站进行通信时所使用的小区特定偏移值不同。例如，小区内的部分UE(如与基站距离较近的近端UE)利用更新后的小区特定偏移值与基站进行通信，小区内的另一部分UE(如与基站距离较近的远端UE)利用更新前的小区特定偏移值与基站进行通信。
示例的，图2b为本公开实施例提供的一种信息更新方法时UE与基站之间的通信示意图，如图2b所示，基站确定出更新后的系统信息，该更新后的系统信息中包括有更新后的小区特定偏移值，之后，基站会向小区内的各个UE广播该更新后的系统信息，其中，近端UE会先接收到该更新后的系统信息，远端UE会后接收到该更新后的系统信息，以及，当各个UE接收到该更新后的系统信息后，会解析该更新后的系统信息以得到更新后的小区特定偏移值，以及，各个UE在得到更新后的小区特定偏移值之后，并不会立刻基于该更新后的小区特定偏移值与基站进行通信，而是会先基于更新前的小区特定偏移值与基站进行通信，当延迟了对应的时间偏移值之后，再基于更新后的小区特定偏移值与基站进行通信，由此可以确保基站对于小区内各个UE所使用的小区特定偏移值有相同的理解，避免了模糊期的出现，确保了通信的可靠性。
综上所述，在本公开一个实施例所提供的信息更新方法之中，UE会接收基站发送的用于指示时间偏移值和/或时间窗口的配置信息，其中，该时间偏移值用于指示更新后的小区特定偏移值的延迟生效时间，时间窗口用于指示更新后的小区特定偏移值的无效时间。当UE接收到基站发送的更新后的小区特定偏移值时，会基于该时间偏移值和/或时间窗口来使用该更新后的小区特定偏移值。由此可知，本公开实施例之中，具体是通过时间偏移值和/或时间窗口来确定更新后的小区特定偏移值的生效时间，以确保小区内各个UE基于更新后的小区特定偏移值向基站发送上行信息时，基站对于不同UE使用的小区特定偏移值有相同的理解，保证通信的可靠性。
图3为本公开一个实施例所提供的一种信息更新方法的流程示意图，该方法由支持卫星通信的UE执行，如图3所示，该信息更新方法可以包括以下步骤：
步骤301、接收基站发送的更新后的小区特定偏移值。
其中，关于步骤301的相关介绍可以参考上述实施例描述，本公开实施例在此不做赘述。
步骤302、接收基站发送的用于指示时间窗口的配置信息。
在本公开的一个实施例之中，该时间窗口可以用于指示更新后的小区特定偏移值的无效时间。步骤303、基于时间偏移值使用更新后的小区特定偏移值。
其中，在本公开的一个实施例之中，基于时间偏移值使用更新后的小区特定偏移值的方法可以包括：在该时间窗口内使用UE特定偏移值(UE-specific offset)与基站进行通信；在时间窗口之后使用更新后的小区特定偏移值与基站进行通信。在该时间窗口之前使用更新前的小区特定偏移值进行通信。
进一步地，上述的“在该时间窗口内使用UE特定偏移值与基站进行通信”的方法可以包括以下至少一种：
方法一、在该时间窗口内，UE基于UE特定偏移值来执行需要使用小区特定偏移值的通信操作；
方法二、在该时间窗口内，UE不执行需要使用cell-specific offset的通信操作。
以及，在本公开的一个实施例之中，上述的通信操作具体可以为UE与基站之间的上行操作和/或下行操作。
需要说明的，在本公开的一个实施例之中，该时间窗口应当满足以下条件：该时间窗口使得基站对于小区内各个UE所使用的小区特定偏移值有相同的理解。即，小区内的各个UE在延迟了时间窗口之后使用更新后的小区特定偏移值与基站进行通信时，对于基站而言不存在模糊期，该模糊期为：由于小区内各个UE与基站之间的距离差异导致各个UE接收到更新后的小区特定偏移值的时间点不同，从而对于基站而言所存在一段时期，在该时期内，小区内的不同UE与基站进行通信时所使用的小区特定偏移值不同。例如，小区内的部分UE(如与基站距离较近的近端UE)利用更新后的小区特定偏移值与基站进行通信，小区内的另一部分UE(如与基站距离较近的远端UE)利用更新前的小区特定偏移值与基站进行通信。
此外，应理解，UE特定偏移值可以通过根据协议约定而确定，也可以通过信令发送而确定，或者根据其它方式而确定，本公开对此不作限制。
综上所述，在本公开一个实施例所提供的信息更新方法之中，UE会接收基站发送的用于指示时间偏移值和/或时间窗口的配置信息，其中，该时间偏移值用于指示更新后的小区特定偏移值的延迟生效时间，时间窗口用于指示更新后的小区特定偏移值的无效时间。当UE接收到基站发送的更新后的小区特定偏移值时，会基于该时间偏移值和/或时间窗口来使用该更新后的小区特定偏移值。由此可知，本公开实施例之中，具体是通过时间偏移值和/或时间窗口来确定更新后的小区特定偏移值的生效时间，以确保小区内各个UE基于更新后的小区特定偏移值向基站发送上行信息时，基站对于不同UE使用的小区特定偏移值有相同的理解，保证通信的可靠性。
图4a为本公开一个实施例所提供的一种信息更新方法的流程示意图，该方法由支持卫星通信的UE执行，如图4a所示，该信息更新方法可以包括以下步骤：
步骤401a、接收基站通过UE specific信令发送的用于指示时间偏移值的配置信息。
其中，关于步骤401a的相关介绍可以参考上述实施例描述。综上所述，在本公开一个实施例所提供的信息更新方法之中，UE会接收基站发送的用于指示时间偏移值的配置信息，其中，该时间偏移值用于指示更新后的小区特定偏移值的延迟生效时间。当UE接收到基站发送的更新后的小区特定偏移值时，会基于该时间偏移值来使用该更新后的小区特定偏移值。由此可知，本公开实施例之中，具体是通过时间偏移值来确定更新后的小区特定偏移值的生效时间，以确保小区内各个UE基于更新后的小区特定偏移值向基站发送上行信息时，基站对于不同UE使用的小区特定偏移值有相同的理解，保证通信的可靠性。

图8为本公开一个实施例所提供的一种信息更新方法的流程示意图，该方法由支持卫星通信的基站执行，如图8所示，该信息更新方法可以包括以下步骤：
步骤801、确定时间偏移值和/或时间窗口。
在本公开的一个实施例之中，基站可以基于其覆盖范围内信号传输的最大RTT来确定时间偏移值。其中，在本公开的一个实施例之中，时间偏移值可以用于指示更新后的小区特定偏移值的延迟生效时间。并且，在本公开的一个实施例之中，小区内不同的UE对应的时间偏移值会有所不同。以及，在本公开的一个实施例之中，该时间偏移值的大小可以与UE和基站之间的距离成反比。例如，距离基站越远的UE对应的时间偏移值越小，距离基站越近的UE对应的时间偏移值越大。
需要说明的是，在本公开的一个实施例之中，该时间偏移值应当满足以下条件：该时间偏移值使得基站对于小区内各个UE所使用的小区特定偏移值有相同的理解。即，小区内的各个UE在延迟了对应的时间偏移值之后使用更新后的小区特定偏移值与基站进行通信时，对于基站而言不存在模糊期，该模糊期为：由于小区内各个UE与基站之间的距离差异导致各个UE接收到更新后的小区特定偏移值的时间点不同，从而对于基站而言所存在一段时期，在该时期内，小区内的不同UE与基站进行通信时所使用的小区特定偏移值不同。例如，小区内的部分UE(例如与基站距离较近的近端UE)利用更新后的小区特定偏移值与基站进行通信，小区内的另一部分UE(例如与基站距离较近的远端UE)利用更新前的小区特定偏移值与基站进行通信。
进一步地，在本公开的一个实施例之中，该时间偏移值可以为一固定值。在本公开的另一个实施例之中，该时间偏移值可以为一可配置值。

在本公开的一个实施例之中，基站向UE发送用于指示时间偏移值和/或时间窗口的配置信息的方法可以包括：

步骤803、向UE发送更新后的小区特定偏移值。
其中，在本公开的一个实施例之中，基站可以是基于UE和基站所处的卫星通信场景，并基于该卫星通信场景来确定是否指示UE更新小区特定偏移值。
具体而言，在本公开的一个实施例之中，基站会基于星历信息确定基站和UE所处的卫星通信场景，其中，若基站确定出UE和基站所处的卫星通信场景为GEO场景，则基站不指示UE进行小区特定偏移值的更新，即基站不向UE发送更新后的小区特定偏移值。若基站确定出UE和基站所处的卫星通信场景为NGSO场景，则基站会向UE发送更新后的特定偏移值。
