Description

无线通信方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及一种无线通信方法、终端设备和网络设备。
背景技术
窄带物联网(Narrow Band Internet of Things，NB-IoT)网络支持的上行信道包括：窄带物理随机接入信道(Narrowband Physical Random Access Channel，NPRACH)和窄带物理上行共享信道(Narrowband Physical Uplink Shared Channel，NPUSCH)。由于在NPRACH和NPUSCH上引入了重复传输机制，同时由于NB-IoT终端只支持半双工type-B模式，即终端设备在同一时刻只能接收数据或者只能发送数据，而不能同时收发数据。因此，针对持续时间较长的上行传输，引入了上行链路(Uplink，UL)间隔(gap)，即上行间隔。该上行间隔主要是为了利用窄带主同步信号(Narrowband Primary Synchronization Signal，NPSS)、窄带辅同步信号(Narrowband Secondary Synchronization Signal，NSSS)或者窄带参考信号(Narrowband Reference Signal，NRS)信号进行同步跟踪和频偏(晶振的频率偏移)补偿。
目前，上行间隔是在协议中预定义的。由于NB-IoT终端具备低移动性的特征，同时在地面网络中，基站也是静止的，因此，NB-IoT终端的信道质量通常变化缓慢，因此上行间隔采用预定义方式定义比较合理。
然而，在非地面通信网络(Non-Terrestrial Network，NTN)网络中，对于非地球同步轨道(Geostationary Earth Orbit，GEO)场景，即使终端设备处于静止状态，终端设备与网络之间的无线信号传输时延，也会随着卫星的快速移动而不断变化。此外，一方面，位于不同轨道高度的非GEO卫星覆盖下的终端设备与网络之间的无线信道变化规律不相同；另一方面，由于NTN网络覆盖范围远大于地面网络，位于同一小区内不同地理位置的终端设备与网络之间的无线信道变化规律也不相同。因此，上行间隔采用预定义的方式并不适用于NTN网络中非GEO场景。
发明内容

第九方面，提供了一种装置，用于实现上述第一方面至第四方面中任一方面或其各实现方式中的方法。
具体地，该装置包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有该装置的设备执行如上述第一方面至第四方面中任一方面或其各实现方式中的方法。

在本申请中，上行间隔的配置信息不是预定义的，而是网络设备配置给终端设备的，可以实现不同的终端设备对应的上行间隔的配置信息的差异性，以适应NTN网络中非GEO场景。
在本申请中，终端设备还可以根据上行间隔的配置信息在上行传输中插入上行间隔，以进行TA预补偿或者TA调整。因此，无论对于TA变小或者变大的情况，终端设备都可以准确地执行TA预补偿或者TA调整，以及上行传输。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。针对本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在介绍本申请技术方案之前，下面将对本申请相关知识进行说明：
一、NTN相关背景
目前第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)正在研究NTN技术，NTN一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信，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或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可以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，且通信距离增大通讯的成本没有明显增加；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、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500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端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。用户间单跳通信的信号传播延迟一般为250ms。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量，卫星采用多波束覆盖地面，一颗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。
二、针对NB-IoT终端的上行间隔
如上所述，NB-IoT网络支持的上行信道包括：NPRACH和NPUSCH。其中，NPRACH用于传输前导码(preamble)。NPUSCH支持format1和format2两种格式，NPUSCH format1用于上行数据传输，NPUSCH format2用于传输混合自动重复请求-确认(Hybrid Automatic Repeat Request-Acknowledgement，HARQ-ACK)反馈信息。
由于在NPRACH和NPUSCH上引入了重复传输机制，其最大重复传输次数可以达到2048。同时由于NB-IoT终端只支持FDD半双工type-B模式，即终端设备在同一时刻只能接收数据或者只能发送数据，而不能同时收发数据。因此，针对持续时间较长的上行传输，引入了上行链路(Uplink，UL)间隔(gap)，即上行间隔。该上行间隔主要是为了利用NPSS、NSSS或者NRS信号进行同步跟踪和频偏(晶振的频率偏移)补偿。
目前，上行间隔是在协议中预定义的。具体如下：
对于NPUSCH：传输256ms数据，通过40ms的上行间隔进行频偏补偿。
对于NPRACH：传输64次前导码后，通过40ms的上行间隔进行频偏补偿。
三、长期演进(Long Term Evolution，LTE)系统中的随机接入过程
图1是基于竞争的四步随机接入过程的流程交互图。
如图1所示，该随机接入流程可以包括以下四个步骤：
步骤1，Msg 1。
终端设备向网络设备发送Msg 1，以告诉网络设备该终端设备发起了随机接入请求，该Msg 1中携带随机接入前导码(Random Access Preamble，RAP)，或称为随机接入前导序列、前导序列、前导码等。同时，Msg 1还可以用于网络设备能估计其与终端设备之间的传输时延并以此校准上行时间。
具体而言，终端设备选择preamble索引(index)和用于发送preamble的PRACH资源；然后该终端设备在PRACH上传输Preamble。其中，网络设备会通过广播系统信息系统信息块(System Information Block，SIB)来通知所有的终端设备，允许在哪些个时频资源上传输preamble，例如，SIB1。
步骤2，Msg 2。
网络设备在接收到终端设备发送的Msg 1后，向终端设备发送Msg 2，即随机接入响应(Random Access Response，RAR)消息。该Msg 2中例如可以携带时间提前量(Time Advance，TA)、上行授权指令例如上行资源的配置、以及临时小区无线网络临时标识(Temporary Cell-Radio Network Temporary Identity，TC-RNTI)等。
终端设备则在随机接入响应窗口(RAR window)内监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)，以用于接收网络设备回复的RAR消息。该RAR消息可以使用相应的随机接入无线网络临时标识符(Random Access Radio Network Temporary Identifier，RA-RNTI)进行解扰。
如果终端设备在该RAR window内没有接收到网络设备回复的RAR消息，则认为此次随机接入过程失败。
如果终端设备成功地接收到一个RAR消息，且该RAR消息中携带的前导码索引(preamble index)与终端设备通过Msg 1发送的前导码的索引相同时，则认为成功接收了RAR，此时终端设备就可以停止RAR window内的监听了。
其中，Msg 2中可以包括针对多个终端设备的RAR消息，每一个终端设备的RAR消息中可以包括该终端设备所采用的随机接入前导码标识(RAP Identify，RAPID)、用于传输Msg 3的资源的信息、TA调整信息、TC-RNTI等。
步骤3，Msg 3。
终端设备在收到RAR消息后，判断该RAR是否为属于自己的RAR消息，例如终端设备可以利用前导码标识进行核对，在确定是属于自己的RAR消息后，终端设备在RRC层产生Msg 3，并向网络设备发送Msg 3。其中需要携带终端设备的标识信息等。
具体地，针对不同的随机接入触发事件，4步随机接入过程的步骤3中的Msg 3可以包括不同的内容，以进行调度传输(Scheduled Transmission)。
例如，对于初始接入的场景，Msg 3可以包括RRC层生成的RRC连接请求(RRC Connection Request)，其中至少携带终端设备的非接入层(Non-Access Stratum，NAS)标识信息，还可以携带例如终端设备的服务临时移动用户标识(Serving-Temporary Mobile Subscriber Identity，S-TMSI)或随机数等。
又例如，对于连接重建场景，Msg 3可以包括RRC层生成的RRC连接重建请求(RRC Connection Re-establishment Request)且不携带任何NAS消息，此外还可以携带例如小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)和协议控制信息(Protocol Control Information，PCI)等。
又例如，对于切换场景，Msg 3可以包括RRC层生成的RRC切换完成消息(RRC Handover Confirm)和终端设备的C-RNTI，还可携带例如缓冲状态报告(Buffer Status Report，BSR)；对于其它触发事件例如上/下行数据到达的场景，Msg 3至少需要包括终端设备的C-RNTI。
步骤4，Msg 4。
网络设备向终端设备发送Msg 4，终端设备正确接收Msg 4完成竞争解决(Contention Resolution)。例如在RRC连接建立过程中，Msg 4中可以携带RRC连接建立消息。
由于步骤3中的终端设备会在Msg 3中携带自己唯一的标识，例如C-RNTI或来自核心网的标识信息(比如S-TMSI或一个随机数)，从而网络设备在竞争解决机制中，会在Msg 4中携带终端设备的唯一标识以指定竞争中胜出的终端设备。而其它没有在竞争解决中胜出的终端设备将重新发起随机接入。
目前LTE中，考虑到终端设备的收发操作之间的转换时间，终端设备在发送Msg1之后，间隔一段时间后启动RAR window。对于NB-IoT终端，RAR window的启动子帧为n+X，其中n为包含前导码的最后一次重复传输所在的最后一个子帧，X的取值根据时分双工(Time Division Duplex，TDD)或者FDD，以及NPRACH重复传输次数来决定。具体的，可以通过表1确定X值。
表1
TDD或者FDD模式 前导码格式 NPRACH的重复次数 X
FDD 0或者1 ≥64 41
FDD 0或者1 <64 4
FDD 2 ≥16 41
FDD 2 <16 4
TDD 任何值 任何值 4
需要说明的是，在本申请中，随机接入响应窗口(RAR window)也被称为RAR接收窗、RAR时间窗等，本申请对此不做限制。
四、NR系统中的定时提前(Timing Advance，TA)机制：
上行传输的一个重要特征是不同终端设备在时频上正交多址接入，即来自同一小区的不同终端设备的上行传输之间互不干扰。为了保证上行传输的正交性，避免小区内干扰，网络设备要求来自同一时刻但不同频域资源的不同终端设备的信号到达网络设备的时间基本上是对齐的。为了保证网络设备侧的时间同步，NR支持上行TA机制。
图2为本申请一实施例提供的gNB侧的时间同步示意图，如图2中的左侧附图所示，在没有采用TA机制时，UE侧的上行时钟和下行时钟是相同的，对于gNB侧发送的一个下行符号，由于不同UE与gNB之间的传播延迟不同，来自不同UE的上行数据到达gNB侧的时间不同步。如图2中的右侧附图所示，UE侧的上行时钟和下行时钟之间有偏移，并且不同UE有各自不同的上行TA值，即引入了TA机制。gNB通过适当地控制每个UE对应的TA值，可以控制来自不同UE的上行数据到达gNB的时间，以使来自不同UE的上行数据到达gNB侧的时间同步，并且与gNB侧的下行定时同步。具体地，对于距离gNB较远的UE，由于有较大的传输时延，就要比距离gNB较近的UE提前发送上行数据。
其中，gNB基于测量UE的上行传输来确定每个UE的TA值。gNB通过两种方式给UE发送TA命令。
初始TA的获取：在随机接入过程，gNB通过测量接收到的前导码(preamble)来确定TA值，并通过RAR的定时提前命令(Timing Advance Command)字段发送给UE。
RRC连接态下TA的调整：虽然在随机接入过程中，UE与gNB取得了上行同步，但上行信号到达gNB的定时可能会随着时间发生变化，因此，UE需要不断地更新其上行TA值，以保持上行同步。如果某个UE的TA值需要校正，则gNB会发送一个定时提前命令(Timing Advance Command)给该UE，要求其调整TA值。该Timing Advance Command是通过Timing Advance Command MAC CE发送给UE的。
如上所述，由于NB-IoT终端具备低移动性的特征，同时在地面网络中，基站也是静止的，因此，NB-IoT终端的信道质量通常变化缓慢，因此上行间隔采用预定义方式定 义比较合理。
然而，在NTN网络中，对于非GEO场景，即使终端设备处于静止状态，终端设备与网络之间的无线信号传输时延，也会随着卫星的快速移动而不断变化。此外，一方面，位于不同轨道高度的非GEO卫星覆盖下的终端设备与网络之间的无线信道变化规律不相同；另一方面，由于NTN网络覆盖范围远大于地面网络，位于同一小区内不同地理位置的终端设备与网络之间的无线信道变化规律也不相同。因此，上行间隔采用预定义的方式并不适用于NTN网络中非GEO场景。
为了解决上述技术问题，本申请可以给不同的NB-IoT终端配置具有差异性的上行间隔，以适用于NTN网络中非GEO场景。
下面结合图3A-图3B，对本申请中的通信系统的架构进行说明。
图3A为本申请实施例提供的一种通信系统的架构示意图。请参见图3A，包括终端设备1101和卫星1102，终端设备1101和卫星1102之间可以进行无线通信。终端设备1101和卫星1102之间所形成的网络还可以称为NTN。在图3A所示的通信系统的架构中，卫星1102可以具有基站的功能，终端设备1101和卫星1102之间可以直接通信。在系统架构下，可以将卫星1102称为网络设备。可选地，通信系统中可以包括多个网络设备1102，并且每个网络设备1102的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。

在本申请实施例中，网络设备可以为小区提供服务，终端设备通过该小区使用的传 输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
下面将对本申请技术方案进行详细阐述：
实施例1
图4为本申请实施例提供的一种无线通信方法的交互流程图，如图4所示，该方法包括如下步骤：
S410：终端设备获取上行间隔的配置信息，其中，上行间隔用于终端设备在上行间隔上进行下行同步和频偏补偿。
S420：终端设备根据上行间隔的配置信息重复传输上行信道上的上行信息。
可选地，上行间隔的配置信息携带在以下任一项中，但不限于此：广播消息、无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制单元(Media Access Control Control Element，MAC CE)、下行控制信息(Downlink Control Information，DCI)。
可选地，上行间隔的配置信息包括：上行间隔的时长，和/或，上行间隔的插入间隔；其中，上行信道每持续插入间隔之后出现一个上行间隔。
示例性地，图5A为本申请实施例提供的NPRACH对应的上行间隔的配置示意图，如图5A所示，NPRACH每持续插入间隔X1之后出现一个时长为Y1的上行间隔。图5B为本申请实施例提供的NPUSCH对应的上行间隔的配置示意图，如图5B所示，NPUSCH每持续插入间隔X2之后出现一个时长为Y2的上行间隔。
值得一提的是，本申请对网络设备如何确定上行间隔的时长，和/或，上行间隔的插入间隔不做限制。
可选地，上行间隔的时长可以是预定义的，网络设备只需要向终端设备配置上行间隔的插入间隔。或者，上行间隔的插入间隔可以是预定义的，网络设备只需要向终端设备配置上行间隔的时长。
可选地，网络设备还可以向终端设备发送上行信道的资源配置。
可选地，上行信道的资源配置携带在以下任一项中，但不限于此：广播消息、RRC信令、MAC CE、DCI。
可选地，上述上行信道可以是NPRACH或者NPUSCH，但不限于此。
可选地，若上行信道是NPRACH，则上述上行信息可以是NPRACH上传输的前导码。若上行信道是NPUSCH，则上述上行信息可以是NPUSCH上传输的上行数据或者HARQ-ACK反馈信息。
可选地，如果网络设备通过广播消息广播NPRACH的资源配置时，其可以一次广播或者配置至少一个NPRACH的资源配置。基于此，上行间隔的配置信息是针对至少一个NPRACH的配置信息，即上述上行间隔的配置信息可以对应于一个NPRACH资源或者多个NPRACH资源。例如：上行间隔的配置信息可以是基于每套NPRACH资源分别配置，也可以是所有NPRACH资源使用相同的上行间隔的配置信息。
可选地，每个NPRACH的资源配置包括以下至少一项，但不限于此：NPRACH的周期，NPRACH资源在一个周期内的起始时间，NPRACH资源的起始子载波位置，NPRACH资源在频域上占用的连续子载波个数，前导码的重复传输次数。
综上，在本申请中，上行间隔的配置信息不是预定义的，而是网络设备配置给终端设备的，可以实现不同的终端设备对应的上行间隔的配置信息的差异性，以适应NTN网络中非GEO场景。
实施例2
对于NTN网络中非GEO场景，由于RTT会发生快速变化，因此，终端设备需要频 繁的调整TA。对于重复次数较多的上行传输，终端设备在重复传输期间也需要不断调整TA。对于TA变小的情况，终端设备可以同时执行TA调整和上行传输，而对于TA变大的情况，终端设备无法同时执行TA调整和上行传输。
为了解决上述技术问题，在本申请中，网络设备也可以为终端设备配置上行间隔的配置信息，当上行信道是NPRACH时，该上行间隔的配置信息用于终端设备在该上行间隔上进行TA预补偿(Timing Advance pre-compensation)。当上行信道是NPUSCH时，该上行间隔的配置信息用于终端设备在该上行间隔上进行TA调整。
需要说明的是，TA预补偿是终端设备计算得到的，该终端设备在随机接入过程中所要进行的TA补偿。
应理解的是，该TA预补偿也被称为TA补偿、TA预补偿值等，本申请对此不做限制。
可选地，当上行信道是NPUSCH时，终端设备可以根据TA调整命令或者基于终端设备自身的TA补偿能力执行TA调整。
需要说明的是，TA调整和TA预补偿都是终端设备调整其TA，在随机接入发送Msg1时，此时终端设备还没有有效的TA，因此进行的是TA预补偿，当终端设备处于连接态时，终端设备会维护一个TA，并且可以调整该TA。
可选地，在本实施例中，上行间隔的配置信息携带在以下任一项中，但不限于此：广播消息、RRC信令、MAC CE、DCI。
可选地，在本实施例中，上行间隔的配置信息包括：所述上行间隔的时长，和/或，所述上行间隔的插入间隔。其中，所述上行信道每持续所述插入间隔之后出现一个所述上行间隔。
值得一提的是，本申请对网络设备如何确定上行间隔的时长，和/或，上行间隔的插入间隔不做限制。
可选地，上行间隔的时长可以是预定义的，网络设备只需要向终端设备配置上行间隔的插入间隔。或者，上行间隔的插入间隔可以是预定义的，网络设备只需要向终端设备配置上行间隔的时长。
可选地，网络设备还可以向终端设备发送上行信道的资源配置。
可选地，上行信道的资源配置携带在以下任一项中，但不限于此：广播消息、RRC信令、MAC CE、DCI。
可选地，上述上行信道可以是NPRACH或者NPUSCH，但不限于此。
可选地，如果网络设备通过广播消息广播NPRACH的资源配置时，其可以一次广播或者配置至少一个NPRACH的资源配置。基于此，上行间隔的配置信息是针对至少一个NPRACH的配置信息，即上述上行间隔的配置信息可以对应于一个NPRACH资源或者多个NPRACH资源。例如：上行间隔的配置信息可以是基于每套NPRACH资源分别配置，也可以是所有NPRACH资源使用相同的上行间隔的配置信息。
可选地，每个NPRACH的资源配置包括以下至少一项，但不限于此：NPRACH的周期，NPRACH资源在一个周期内的起始时间，NPRACH资源的起始子载波位置，NPRACH资源在频域上占用的连续子载波个数，前导码的重复传输次数。
综上，在本申请中，对于NTN网络中非GEO场景，终端设备可以根据上述上行间隔的配置信息在上行传输中间插入上行间隔，以进行TA预补偿或者TA调整。因此，无论对于TA变小或者变大的情况，终端设备都可以准确地执行TA预补偿或者TA调整，以及上行传输。
需要说明的是，为了方便起见，当上行信道是NPRACH，且上行间隔用于终端设备在该上行间隔上进行下行同步和频偏补偿时，这种情况，将该上行间隔称为第一上行间隔，当上行信道是NPRACH，且上行间隔用于终端设备在该上行间隔上进行TA预补偿时，这种情况，将该上行间隔称为第二上行间隔，当上行信道是NPUSCH，且上行间隔 用于终端设备在该上行间隔上进行下行同步和频偏补偿时，这种情况，将该上行间隔称为第三上行间隔，当上行信道是NPUSCH，且上行间隔用于终端设备在该上行间隔上进行TA调整时，这种情况，将该上行间隔称为第四上行间隔。
可选地，上述第一上行间隔、第二上行间隔、第三上行间隔和第四上行间隔可以完全不同，也可以部分相同，又或者是完全相同。例如：第一上行间隔与第二上行间隔可以相同，第三上行间隔与第四上行间隔可以相同。或者，第一上行间隔与第三上行间隔可以相同，第二上行间隔与第四上行间隔可以相同。又或者，第一上行间隔、第二上行间隔可、第三上行间隔和第四上行间隔均不同。再或者，第一上行间隔、第二上行间隔可、第三上行间隔和第四上行间隔均相同。总之，本申请对此不做限制。
实施例3
如上所述，目前LTE中，考虑到终端设备的收发操作之间的转换时间，终端设备在发送Msg1之后，间隔一段时间后启动随机接入响应窗口。对于NB-IoT终端，RAR window的启动子帧为n+X，其中n为包含前导码的最后一次重复传输所在的最后一个子帧，X的取值根据TDD或者FDD，以及NPRACH重复传输次数来决定。具体的，可以通过表1确定X值。
其中，表1中X＝41，实际上是40+1，这里的40即为预定义的上行间隔的时长。如本申请的，在NTN网络的非GEO场景下，上行间隔不再是预定义的，而是网络设备配置的。基于此，随机接入响应窗口的开启时间也会发生变化。下面对此做详细说明：
可选地，假设上述第一上行间隔的插入间隔和时长分别用X1和Y1表示。那么随机接入响应窗口的开启时间可以是n+Z1。n表示前导码的最后一次重复传输使用的最后一个子帧，Z1是由前导码的重复传输总时长，或者，在前导码的整个重复传输中插入的最后一个第一上行间隔的结束时间到前导码的整个重复传输的结束时间的时长，以及终端设备和网络设备之间RTT确定的。
可选地，假设Z1是由前导码的重复传输总时长决定的，若前导码的重复传输总时长大于或等于X1，则Z1＝max{Y1+1，RTT}或者Z1＝max{Y1+1，RTT+1}。例如：图6为本申请一实施例提供的前导码、第一上行间隔和随机接入响应窗口的关系示意图，如图6所示，这里的前导码的重复传输总时长大于X1，这种情况下，Z1＝max{Y1+1，RTT}或者Z1＝max{Y1+1，RTT+1}。
若前导码的重复传输总时长小于X1，则Z1＝max{4，RTT}或者Z1＝max{4，RTT+1}。
可选地，假设Z1是由在前导码的整个重复传输中插入的最后一个第一上行间隔的结束时间到前导码的整个重复传输的结束时间的时长，以及终端设备和网络设备之间RTT确定的。若前导码的重复传输总时长等于X1，则Z1＝max{Y1+1，RTT}或者Z1＝max{Y1+1，RTT+1}。例如：图7为本申请再一实施例提供的前导码、第一上行间隔和随机接入响应窗口的关系示意图，如图7所示，这里的前导码的重复传输总时长等于X1，这种情况下，Z1＝max{Y1+1，RTT}或者Z1＝max{Y1+1，RTT+1}。或者，在前导码的整个重复传输中插入的最后一个第一上行间隔的结束时间到前导码的整个重复传输的结束时间等于X1，则Z1＝max{Y1+1，RTT}或者Z1＝max{Y1+1，RTT+1}。例如：图8为本申请又一实施例提供的前导码、第一上行间隔和随机接入响应窗口的关系示意图，如图8所示，这里的在前导码的整个重复传输中插入的最后一个第一上行间隔的结束时间到前导码的整个重复传输的结束时间等于X1，这种情况下，Z1＝max{Y1+1，RTT}或者Z1＝max{Y1+1，RTT+1}。若前导码的重复传输总时长小于X1，则Z1＝max{4，RTT}或者Z1＝max{4，RTT+1}。或者，在前导码的整个重复传输中插入的最后一个第一上行间隔的结束时间到前导码的整个重复传输的结束时间小于X1，则Z1＝max{4，RTT}或者Z1＝max{4，RTT+1}。
以上是在第一上行间隔的基础上确定随机接入响应窗口的开启时间。
实际上，在本申请中，也可以在第二上行间隔的基础上确定随机接入响应窗口的开 启时间，当然，在确定随机接入响应窗口的开启时间只能基于第一上行间隔或者第二上行间隔确定。
可选地，随机接入响应窗口的开启时间是n+Z3。n表示前导码的最后一次重复传输使用的最后一个子帧，Z3是由前导码的重复传输总时长，或者，在前导码的整个重复传输中插入的最后一个第二上行间隔的结束时间到前导码的整个重复传输的结束时间的时长，以及终端设备和网络设备之间RTT确定的。
可选地，若前导码的重复传输总时长大于或等于X3，则Z3＝max{Y3+1，RTT}或者Z3＝max{Y3+1，RTT+1}。若前导码的重复传输总时长小于X3，则Z3＝max{4，RTT}或者Z3＝max{4，RTT+1}。其中，X3表示第二上行间隔的插入间隔，Y3表示第二上行间隔的时长。
可选地，若前导码的重复传输总时长等于X3，或者，在前导码的整个重复传输中插入的最后一个第二上行间隔的结束时间到前导码的整个重复传输的结束时间等于X3，则Z3＝max{Y3+1，RTT}或者Z3＝max{Y3+1，RTT+1}。若前导码的重复传输总时长小于X3，或者，在前导码的整个重复传输中插入的最后一个第二上行间隔的结束时间到前导码的整个重复传输的结束时间小于X3，则Z3＝max{4，RTT}或者Z3＝max{4，RTT+1}。
值得一提的是，关于根据第二时间间隔确定随机接入响应窗口的开启时间，与，根据第一时间间隔确定随机接入响应窗口的开启时间的方法类似，本申请对此不再赘述。
综上，在本申请提供了在NTN网络的非GEO场景下确定随机接入响应窗口的开启时间的方法。
