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。
目前，3GPP正在研究NTN技术。在NTN系统中，一般采用卫星通信的方式向地面UE提供通信服务。相对于地面蜂窝网通信，卫星通信具有很多独特的优点。首先，卫星通信不受用户地域的限制；例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备的区域，或者由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此，在理论上地球上每一个角落都可以被卫星通信覆盖。其次，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都能够以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区之间的数字鸿沟，促进这些地区的发展。再次，卫星通信距离远，且通信距离增大时通讯成本没有明显增加。最后，卫星通信的稳定性高，不受自然灾害的限制。
通信卫星按照轨道高度的不同分为低地球轨道(Low-Earth Orbit，LEO)卫星、中地球轨道(Medium-Earth Orbit，MEO)卫星、地球同步轨道(Geostationary Earth Orbit，GEO)卫星、高椭圆轨道(High Elliptical Orbit，HEO)卫星等等。目前阶段主要研究的是LEO和GEO。
LEO
低轨道卫星高度范围为500千米(km)～1500km，相应轨道周期约为1.5小时～2小时。UE间单跳通信的信号传播延迟一般小于20毫秒(ms)。最大卫 星可视时间20分钟。信号传播距离短，链路损耗少，对UE的发射功率要求不高。
GEO
地球同步轨道卫星，轨道高度为35786km，围绕地球旋转周期为24小时。UE间单跳通信的信号传播延迟一般为250ms。
为了保证通信卫星的覆盖以及提升整个卫星通信系统的系统容量，通信卫星采用多波束覆盖地面，一颗通信卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
目前，存在至少两种NTN场景：基于透传载荷(payload)的NTN场景和基于再生载荷的NTN场景。图1示出了一种基于透传载荷的NTN场景的示意图，图2示出了一种基于再生载荷的NTN场景的示意图。
NTN网络由以下网元组成：
·1个或者多个网络设备16：用于连接卫星14和地面上的数据网络18；
·馈线链路(Feeder Link)：用于网络设备16和卫星14之间通信的链路；
·服务链路(Service Link)：用于UE 12和卫星14之间通信的链路；
·卫星14：从其提供的功能上可以分为透传载荷和再生载荷这两种。
·透传载荷：只提供无线频率滤波，频率转换和放大的功能。只提供信号的透明转发，不会改变其转发的波形信号。
·再生载荷：除了提供无线频率滤波，频率转换和放大的功能，还可以提供解调/解码，路由/转换，编码/调制的功能。其具有基站的部分或者全部功能。
·ISL(Inter-Satellite Links，星间链路)：存在于再生载荷的NTN场景中。
在NTN系统中，UE的上行同步需要卫星星历和公共定时提前参数信息。其中，卫星星历用于补偿Service Link的时延；commonTA参数信息用于补偿FeederLink的时延。
上述卫星星历和commonTA参数信息会放在NTN-SIB中发送，这些信息的生效时间有两种指示方式：
方式1：显性指示，卫星星历和commonTA参数信息的生效时间是NTN-SIB中包含的epochtime所指示的下行子帧的起始位置。其中，指示的Epochtime是系统帧号(System Frame Number，SFN)+子帧号(subframenumber)。
方式2：隐性指示，卫星星历和commonTA参数信息的生效时间是NTN-SIB所在的系统信息窗(System Informationwindow，SIwindow)的终止位置。
由于卫星星历和common TA参数信息都是时变的，因此只在一定时间内是有效的，其有效时间段也会在NTN-SIB里进行通知。如果卫星星历和common TA参数信息的epoch time采用显示指示的方式来指示，那么存在这样的情况，UE在第一接收时间T11上读取包含上行同步辅助信息的NTN-SIB，获取到上一次的卫星星历和common TA参数信息的第一生效时间T12和第一有效时间长度，UE可以推算出第一失效时间T13；在第一失效时间T13之前的第二接收时间T21上读取新的NTN-SIB，获取到新的卫星星历和common TA参数信息的第二生效时间T22，而第二生效时间T22是超过第一失效时间T13的，这样就会造成一段模糊时间T1，如图3所示。在上述模糊时间内，UE行为尚未定义。
图4示出了本公开一个示例性实施例提供的终端行为的确定方法的流程图，该方法应用于NTN场景中，由UE执行，该方法包括：
步骤201，确定在模糊时间内的终端行为。
终端在存在模糊时间的情况下，确定在模糊时间内的终端行为。其中，模糊时间为上一个上行同步辅助信息的第一失效时间与当前上行同步辅助信息的第二生效时间之间的第一时间段。示例性的，第一时间段包括上一个上行同步辅助信息的第一失效时间与当前上行同步辅助信息的第二生效时间之间的间隔时间的部分或者全部。
上行同步辅助信息用于上行同步。上行同步是指在同一小区中，使用同一时隙的不同位置的终端发送的上行信号同时到达网络设备的接收天线，即同一时隙不同终端的信号达到网络设备的接收天线时保持同步。在上行同步的场景中，终端在上一个上行同步辅助信息的第一失效时间与当前上行同步辅助信息的第二生效时间之间存在模糊时间的情况下，确定在模糊时间内的终端行为。示例性的，上行同步辅助信息携带在系统信息块中。
示例性的，模糊时间为上一个上行同步辅助信息的第一失效时间与当前上行同步辅助信息的第二生效时间之间的全部间隔时间，终端确定在上述全部间隔时间内的终端行为。或者，模糊时间为上一个上行同步辅助信息的第一失效时间与当前上行同步辅助信息的第二生效时间之间的部分间隔时间，终端确定在上述部分间隔时间内的终端行为。
可选地，终端行为(UE behavior)包括以下至少一项：
·通知无线资源控制(Radio ResourceControl，RRC)层释放RRC连接，终端进入RRC空闲态或者RRC休眠态。
在终端处于RRC连接态(也即RRC_connected态)的情况下，终端确定在模糊时间内的终端行为是通知RRC层释放RRC连接，从RRC连接态切换至RRC空闲态(也即RRC_idle态)或者RRC休眠态(也即RRC_inactive态)。
·清空混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)缓存。
终端确定在模糊时间内的终端行为是清空HARQ缓存。
·在配置有物理上行控制信道(Physical Uplink Control CHannel，PUCCH)的情况下，通知RRC层释放PUCCH。
终端在配置有PUCCH的情况下，确定在模糊时间内的终端行为是通知RRC层释放PUCCH。
·在配置有探测参考信号(Sounding Reference Signal，SRS)的情况下，通知RRC层释放SRS。
终端在配置有SRS的情况下，确定在模糊时间内的终端行为是通知RRC层释放SRS。
·清空预配置的下行传输。
终端在预配置有下行传输的情况下，确定在模糊时间内的终端行为是清空预配置的下行传输。
示例性的，下行传输包括物理下行共享信道和/或物理下行控制信道上的传输。
·清空预配置的上行传输。
终端在预配置有上行传输的情况下，确定在模糊时间内的终端行为是清空预配置的上行传输。
示例性的，上行传输包括物理上行共享信道和/或物理上行控制信道上的传输。
·清空用于半静态信道状态信息(Channel State Information，CSI)上报的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)资源。
终端确定在模糊时间内的终端行为是清空用于半静态CSI上报的PUSCH资源。其中，半静态是指对CSI的周期性的上报。
·维护定时提前组(TimeAdvance Group，TAG)的N TA，N TA是网络设备指示终端的下行链路和上行链路之间的定时提前。
其中，TAG是指一个定时提前对应的一组载波。维护TAG的N TA，也即是保留一组载波对应的N TA。终端确定在模糊时间内的终端行为是维护TAG的N TA。
·确定时间校准定时器(time Alignment Timers)已超时。
终端确定在模糊时间内的终端行为是确定时间校准定时器已超时。其中，时间校准定时器是监测上行时间同步的定时器。
可选地，当前上行同步辅助信息的第二生效时间是指上述第二生效时间所指示的下行子帧的起始位置。
综上所述，本实施例提供的终端行为的确定方法，在上行同步场景下，终端在上一个上行同步辅助信息的第一失效时间与当前上行同步辅助信息的第二生效时间之间存在模糊时间的情况下，可以确定在模糊时间内的终端行为，用于支持模糊时间内的终端行为的确定。
示例性的，终端在获取到系统信息块之后，首先确定是否存在模糊时间，因此，步骤201可以包括步骤301，如图5所示，步骤如下：
步骤301，在第二生效时间满足模糊时间的存在条件的情况下，确定在模糊时间内的终端行为。
终端确定当前上行同步辅助信息的第二生效时间满足模糊时间的存在条件，之后确定在模糊时间内的终端行为。
可选地，上述模糊时间的存在条件包括以下至少一种：
·第二生效时间晚于第一失效时间。
也即当前上行同步辅助信息的第二生效时间晚于上一个上行同步辅助信息的第一失效时间。
·第一时间晚于第一失效时间，第一时间是第二生效时间减去当前上行同步辅助信息的有效时间段后的时间。
也即第一时间是当前上行同步辅助信息的第二生效时间减去当前上行同步辅助信息的有效时间段后的时间。
示例性的，终端确定当前上行同步辅助信息的第二生效时间晚于上一个上行同步辅助信息的第一失效时间，则确定在模糊时间内的终端行为。
或者，终端确定第一时间晚于上一次上行同步辅助信息的第一失效时间，则确定在模糊时间内的终端行为。
可选地，在当前上行同步辅助信息的第二生效时间晚于上一个上行同步辅助信息的第一失效时间的情况下，第一时间段是上一个上行同步辅助信息的第一失效时间与当前上行同步辅助信息的第二生效时间之间的间隔时间。示例性的，如图3所示，上一个上行同步辅助信息的第一失效时间T13与当前上行同步辅助信息的第二生效时间T22之间的全部间隔时间即是模糊时间T1。
可选地，在第一时间晚于上一个上行同步辅助信息的第一失效时间的情况下，第一时间段是上一个上行同步辅助信息的第一失效时间与当前上行同步辅助信息的第二生效时间之间的间隔时间，如图3所示。
或者，在第一时间晚于上一个上行同步辅助信息的第一失效时间的情况下，第一时间段是上一个上行同步辅助信息的第一失效时间与第一时间之间的间隔时间，也即模糊时间是上一个上行同步辅助信息的第一失效时间与当前上行同步辅助信息的第二生效时间之间的部分间隔时间，如图6所示，第一时间T23是当前上行同步辅助信息的第二生效时间T22减去当前上行同步辅助信息的有效时间段T24之后的时间，上一个上行同步辅助信息的第一失效时间T13与第一时间T23之间的间隔时间即是模糊时间T2。
在一些实施例中，终端确定了模糊时间内的终端行为之后，在模糊时间内执行确定出的终端行为；进一步地，在当前上行同步辅助信息的第二生效时间后的随机接入时机(Random Access CHanneloccasion，RACHoccasion)发送前导(preamble)信号，发起随机接入过程。可选地，终端在随机接入时机使用系统消息块中的当前上行同步辅助信息确定第一定时提前(Timing Advance，TA)，并基于该第一定时提前发送前导信号，从而发起随机接入过程。
示例性的，上述系统信息块包括主系统信息块(Master Information Block，MIB)和SIB。终端在随机接入时机使用NTN-SIB中的当前上行同步辅助信息确定第一定时提前，并基于第一定时提前发送前导信号，从而发起随机接入过程。其中，NTN-SIB可以是SIBx，x的取值为{1,2,3,4,5,6,7,8,9,10,11,…}中的任意一个。
综上所述，本实施例提供的终端行为的确定方法，在当前上行同步辅助信息的第二生效时间符合模糊时间的存在条件的情况下，确认在模糊时间内的终端行为，定义了模糊时间、以及模糊时间的存在条件。
图7示出了本公开一个示例性实施例提供的随机接入方法的流程图，该方法应用于NTN场景中，由UE执行，该方法包括：
步骤401，在NTN-SIB中的当前上行同步辅助信息的第二生效时间满足模糊时间的存在条件的情况下，确定在模糊时间内的终端行为。
终端在NTN-SIB中的当前上行同步辅助信息的第二生效时间晚于上一个上行同步辅助信息的第一失效时间的情况下，确定在模糊时间内的终端行为。
或者，终端在第一时间晚于上一个上行同步辅助信息的第一失效时间的情 况下，确定在模糊时间内的终端行为；其中，第一时间是NTN-SIB中的当前上行同步辅助信息的第二生效时间减去当前上行同步辅助信息的有效时间段后的时间。
示例性的，终端在NTN-SIB中的当前上行同步辅助信息的第二生效时间满足模糊时间的存在条件的情况下，还确定模糊时间。
可选地，终端根据当前上行同步辅助信息的第二生效时间确定模糊时间；或者，终端根据当前上行同步辅助信息的第二生效时间和上一个上行同步辅助信息的第一失效时间确定模糊时间；或者，终端根据当前上行同步辅助信息的第二生效时间、当前上行同步辅助信息的有效时间段和上一个上行同步辅助信息的第一失效时间确定模糊时间。
比如，终端将上一个上行同步辅助信息的第一失效时间与NTN-SIB中的当前上行同步辅助信息的第二生效时间之间的间隔时间确定为模糊时间。又比如，终端将NTN-SIB中的当前上行同步辅助信息的第二生效时间减去当前上行同步辅助信息的有效时间段，得到第一时间；将上一个上行同步辅助信息的第一失效时间与第一时间之间的间隔时间确定为模糊时间。
需要说明的是，本公开实施例中对模糊时间的确定与终端行为的确定的先后执行顺序不加以限定。比如，二者可以是同时执行：终端在NTN-SIB中的当前上行同步辅助信息的第二生效时间满足模糊时间的存在条件的情况下，确定模糊时间，并确定在模糊时间内的终端行为。或者，终端在NTN-SIB中的当前上行同步辅助信息的第二生效时间满足模糊时间的存在条件的情况下，首先确定模糊时间，之后确定在模糊时间内的终端行为。
步骤402，在模糊时间内执行终端行为。
可选地，终端行为包括以下至少一种：
·Notify RRC layer to release the RRC-connection and fall back to RRC-idle/RRC-inactive.
也即，通知RRC层释放RRC连接，终端进入RRC空闲态或者RRC休眠态。

·Notify RRC to release SRS,if configured.
也即，在配置有SRS的情况下，通知RRC层释放SRS。
·Clear any configured downlink assignments.
也即，清空预配置的下行传输。
·Clear any configured uplink grants.
也即，清空预配置的上行传输。
·Clear any PUSCH resource for semi-persistent CSI reporting.
也即，清空用于半静态CSI上报的PUSCH资源。
·Maintain N TA of this TAG.
也即，维护TAG的N TA。
·Consider the running timeAlignmentTimers as expired.
也即，确定时间校准定时器已超时。
步骤403，在当前上行同步辅助信息的第二生效时间后的随机接入时机发送前导信号，发起随机接入过程。
终端在随机接入时机使用当前上行同步辅助信息确定第一定时提前，并基于第一定时提前发送前导信号，发起随机接入过程。
