Description

上行传输方法、装置、设备及存储介质 技术领域
本申请实施例涉及通信技术领域，特别涉及一种上行传输方法、装置、设备及存储介质。
背景技术
为了确保网络侧的上行和下行的时间同步，3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)提出了定时提前(Timing Advance，TA)机制。
定时提前机制一般用于终端设备的上行传输，是指为了将终端设备传输的上行数据包在期望的时刻到达网络侧，按照所预估的由于距离等引起的射频传输时延，而提前相应的时间发出上行数据包。在TN(Terrestrial Networks，地面网络)系统中，具体的定时提前量由网络侧基于终端设备发送的随机接入前导码或者其他上行信号计算得出，然后网络侧再通过定时提前命令(Timing Advance Command，TAC)通知给终端设备，从而终端设备可以获知定时提前量，并按照网络侧所通知的定时提前量提前相应的时间执行上行传输。
然而，由于NTN(Non-Terrestrial Networks，非地面网络)系统中终端设备与网络侧之间存在较大时延，TN系统中定时提前量的确定方式不完全适用于NTN系统。因此，针对NTN系统，如何确定定时提前量并按照定时提前量执行上行传输，还需要进一步地讨论和研究。

附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的系统架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
请参考图1，其示出了本申请一个实施例提供的系统架构的示意图。该系统架构可以包括：网络设备10和终端设备20。
网络设备10是用于为终端设备20提供无线通信服务的设备。网络设备10与终端设备20之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。网络设备10的数量可以有多个，两个邻近的网络设备10之间也可以通过有线或者无线的方式进行通信。终端设备20可以在不同的网络设备10之间进行切换，也即与不同的网络设备10建立连接。
在一个示例中，如图2所示，以NTN系统为例，NTN系统中的网络设备10可以是卫星11。一颗卫星11可以覆盖一定范围的地面区域，为该地面区域上的终端设备20提供无线通信服务。另外，卫星11可以围绕地球做轨道运动，通过布设多个卫星11，可以实现对地球 表面的不同区域的通信覆盖。
相比于地面的蜂窝通信网络，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，且随着通信距离的增大，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。
可选地，通信卫星按照轨道高度的不同分为LEO(Low-Earth Orbit，低地球轨道)卫星、MEO(Medium-Earth Orbit，中地球轨道)卫星、GEO(Geostationary Earth Orbit，地球同步轨道)卫星、HEO(High Elliptical Orbit，高椭圆轨道)卫星等等。目前阶段主要研究的是LEO和GEO。
1、LEO。
低轨道卫星高度范围为500km(千米)至1500km，相应轨道周期约为1.5小时至2小时。用户间单跳通信的信号传播延迟一般小于20ms(毫秒)。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。
2、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。
在另一个示例中，如图3所示，以TN系统为例，TN系统中的网络设备10可以是基站12。基站12是一种部署在接入网中用以为终端设备20提供无线通信功能的装置。基站12可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在NR(New Radio，新空口)系统中，称为gNodeB或者gNB。
随着通信技术的演进，“网络设备”这一名称可能会变化。为方便描述，本申请实施例中，为终端设备20提供无线通信功能的装置统称为基站。应理解，NTN系统包括透明转发和再生转发这两种传输模式，在再生转发这一传输模式下，卫星具有全部或者部分基站的功能。
另外，本申请实施例中涉及的终端设备20，可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(Terminal Device)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端设备。
为了确保网络侧的上行和下行的时间同步，3GPP提出了定时提前机制。定时提前机制一般用于终端设备的上行传输，是指为了将终端设备传输的上行数据包在期望的时刻到达网络侧，按照所预估的由于距离等引起的射频传输时延，而提前相应的时间发出上行数据包。在定时提前机制下，终端设备发送上行数据包的系统帧相比于对应的下行帧提前了一定的时间，从而可以确保网络侧正确接收终端设备所发送的上行数据包。
在TN系统中，具体的定时提前量由网络侧基于终端设备发送的随机接入前导码或者其他上行信号计算得出，然后网络侧再通过定时提前命令(TAC)通知给终端设备，从而终端设备可以获知定时提前量，并按照网络侧所通知的定时提前量提前相应的时间执行上行传输。其中，在初始接入期间，定时提前量N TA由N TA＝T A*16*64/2 μ计算得到，T A等于0、1、 2、……、3846；在其他情况下，定时提前量N TA由N TA-new＝N TA-old+(T A-31)*16*64/2 μ计算得到，T A等于0、1、2、……、63。
不同于TA系统，由于NTN系统中终端设备与网络侧之间存在较大时延，从而TN系统中定时提前量的确定方式不完全适用于NTN系统。相关技术中，NTN系统中的定时提前量是通过开环调整和闭环调整相结合的方式来获得的，其中，在本申请实施例中，开环调整包括利用终端设备的位置、卫星的星历信息、卫星和参考点之间的时延来调整；闭环调整包括利用TAC来调整。但正是由于NTN系统中存在较大的时延，在开环调整和闭环调整相结合的调整机制中，会出现开环调整和闭环调整对相同时间段都进行调整的情况，这样会导致对定时提前量进行双重调整，造成定时提前量的误差偏大，影响定时同步性能。
例如，如图4所示，终端设备在T1时刻和T3时刻均需进行上行传输，按照相关技术中的定时提前量的调整方式，若在T3时刻进行定时提前量调整时，已经获得了T3时刻最新的开环信息，那么T3时刻的定时提前量的调整是基于T2时刻的闭环调整和T3时刻的开环调整得到的。也就是说，T3时刻的定时提前量T TA通过如下方式计算得到：
T TA＝(N TA+N TA,UE-specific+N TA,common+N TA,offset)×T C。
其中，T TA是指闭环调整的结果，即终端设备基于TAC获取的时延；N TA,UE-specific是指服务链路上终端设备所估计出来的时延；N TA,common是指网络侧控制的卫星和参考点之间的时延，可能还包括网络侧的一些定时偏移等；N TA,offset是指用于计算定时提前量的固定偏移值；T C是指通信协议预定义的时间单位。
基于上述定时提前量的调整方式，如图4所示，T2时刻的闭环调整可能对T1时刻至T2时刻之间的时间段进行了调整，T3时刻的开环调整中，若更新了T3时刻的开环信息，那么在T3时刻相当于对T1时刻的开环信息进行了调整，而T1时刻至T3时刻之间的时间段包括T1时刻至T2时刻之间的时间段，也就是说，T3时刻的开环调整和T2时刻的闭环调整都会对T1时刻至T2时刻之间的时间段进行调整，从而出现重复调整的情况，导致定时提前量的调整力度过大，可能会出现调整错误的问题，这样会造成网络侧的上下行时序不对齐，造成定时错误。
例如，如图5所示，正确调整上下行时序所产生的效果应该是，网络侧的上行链路(UL，Uplink)接收时刻与下行链路(DL，Downlink)发送时刻对齐。而如果终端设备对相同时间段进行了闭环调整和开环调整，那么定时提前量就会偏大，如图5所示，导致终端设备提前了更多的时间执行上行传输，这样网络侧的UL接收时刻和DL发送时刻就无法对齐，造成定时错误的情况。
基于此，本申请实施例提供了一种上行传输方法，可用于解决上述技术问题，避免对定时提前量进行重复调整的情况，提升定时提前量的准确性。下面，结合几个实施例对本申请提供的技术方案进行介绍说明。
请参考图6，其示出了本申请一个实施例提供的上行传输方法的流程图，该方法可应用于图1至图3所示的系统架构中，该方法可以包括如下几个步骤中的至少部分步骤。
步骤610，基于调整信息对定时提前量进行调整，得到调整后的定时提前量。
终端设备基于调整信息对定时提前量进行调整。本申请实施例中用于调整定时提前量的信息均称为调整信息，或者说，本申请实施例对调整信息的内容不作限定，可选地，调整信息包括以下至少一项：开环调整信息、闭环调整信息、固定偏移值(如上述N TA,offset)。
开环调整信息是指终端设备开环调整时使用的信息，用于终端设备估计服务链路上的时延，在本申请实施例中，开环调整信息也可以用于终端设备调整卫星和参考点之间的时延；闭环调整信息是指终端设备闭环调整时使用的信息，用于终端设备获取网络侧计算的时延。本申请实施例对开环调整信息和闭环调整信息的内容均不作限定，可选地，开环调整信息包括以下至少一项：GNSS(Global Navigation Satellite System，全球卫星导航系统)信息、星 历信息、第一时延信息，该第一时延信息用于指示参考点与卫星之间的时延；可选地，闭环调整信息包括：定时提前命令(TAC)。
应理解，本申请实施例中，定时提前量的调整信息中除了固定偏移值之外，不属于闭环调整信息的部分均可以认为是开环调整信息，也就是说，本申请实施例中的开环调整不局限于终端设备估计终端设备与卫星之间的时延，还包括网络侧控制的卫星和参考点之间的时延等。示例性地，对于T TA＝(N TA+N TA,UE-specific+N TA,common+N TA,offset)×T C，N TA,offset为固定偏移值，N TA为闭环调整信息，N TA,UE-specific和N TA,common均为开环调整信息。
在调整信息包括开环调整信息和闭环调整信息的情况下，上述终端设备基于调整信息对定时提前量进行调整，包括：基于开环调整信息对定时提前量进行开环调整，以及基于闭环调整信息对定时提前量进行闭环调整。其中，开环调整既可以在闭环调整之前执行，也可以在闭环调整之后执行，还可以与闭环调整同时执行，本申请实施例对此不作限定。
为了避免终端设备对定时提前量进行重复调整的情况，在开环调整与闭环调整相结合的方案下，本申请实施例中，终端设备要么采用上一次获取的开环调整信息中的至少部分信息，要么采用上一次获取的闭环调整信息中的至少部分信息。也就是说，调整信息包括第一调整信息或者第二调整信息，其中，第一调整信息包括上一次获取到的开环调整信息中的至少部分信息，第二调整信息包括上一次获取到的闭环调整信息中的至少部分信息。
在终端设备采用了上一次获取的开环调整信息中的至少部分信息进行开环调整的情况下，闭环调整可以采用本次获取的闭环调整信息，也即，在一个示例中，上述步骤620包括：在调整信息包括第一调整信息的情况下，基于第一调整信息和第三调整信息，对定时提前量进行调整，得到调整后的定时提前量；第三调整信息包括本次获取到的闭环调整信息。
在终端设备采用了上一次获取的闭环调整信息中的至少部分信息进行闭环调整的情况下，开环调整可以采用本次获取的开环调整信息，也即，在一个示例中，上述步骤620包括：在调整信息包括第二调整信息的情况下，基于第二调整信息和第四调整信息，对定时提前量进行调整，得到调整后的定时提前量；第四调整信息包括本次获取到的开环调整信息。
有关定时提前量的调整过程的其它介绍说明，请参见下述实施例，此处不多赘述。
步骤620，基于调整后的定时提前量，执行上行传输。
通过上述步骤610，终端设备可以得到调整后的定时提前量，并基于调整后的定时提前量执行上行传输。其中，上行传输包括发送上行数据包。示例性地，终端设备将上行传输相对于网络侧的下行帧提前调整后的定时提前量执行，以确保上行传输到达网络侧的系统帧与对应的下行帧之间对齐。
在一个示例中，假设终端设备上一次执行上行传输的时刻为第五时刻，终端设备本次执行的上行传输所对应的闭环调整的时刻为第六时刻，终端设备本次执行的上行传输所对应的开环调整的时刻为第七时刻，并且，第七时刻是第六时刻之后的时刻，第六时刻是第五时刻之后的时刻，如图7所示，那么，终端设备在第六时刻进行一次闭环调整、在第七时刻进行一次开环调整，以确定第七时刻在执行本次上行传输时使用的定时提前量。
其中，第五时刻和第六时刻之间的时长大于或等于第二时延信息，该第二时延信息用于指示终端设备与基站之间的时延，如往返时延(Round Trip Time，RTT)。可选地，第二时延信息为以下任意一项：第五时刻的第二时延信息(上一次执行上行传输时刻的第二时延信息)、第六时刻的第二时延信息(本次执行上行传输所对应的闭环调整时刻的第二时延信息)、用于确定RAR Window(Random Access Response Window，随机接入响应窗口)的第二时延信息。
综上所述，本申请实施例提供的技术方案，通过开环调整与闭环调整相结合来调整定时提前量，适用于NTN系统中终端设备的上行传输，确保了网络侧上下行的时间同步。并且，本申请实施例中，对定时提前量的调整，要么是开环调整采用上一次获取的开环调整信息中的至少部分信息，要么是闭环调整采用上一次获取的闭环调整信息中的至少部分信息，有效避免了对相同时间段进行重复调整的情况，提升了定时提前量的准确性，有助于提升系统的 定时同步性能。
由上述实施例可知，在开环调整与闭环调整相结合的方案中，终端设备要么在开环调整时采用上一次获取的开环调整信息中的至少部分信息，要么在闭环调整时采用上一次获取的闭环调整信息中的至少部分信息。下面，分别针对几种可能的情况进行介绍说明。
首先，介绍说明终端设备采用上一次获取的开环调整信息中的至少部分信息。
在一个示例中，第一调整信息包括：星历信息、GNSS信息、第一时延信息；第一时延信息用于指示参考点与卫星之间的时延。
其中，第一调整信息包括上一次获取的开环调整信息中的至少部分信息，从而结合本示例，第一调整信息中的星历信息、GNSS信息、第一时延信息中的至少部分信息，是上一次获取的开环调整信息中的。例如，第一调整信息中的GNSS是上一次获取的开环调整信息中的GNSS信息，或者，第一调整信息中的星历信息是上一次获取的开环调整信息中的星历信息，或者，第一调整信息中的第一时延信息是上一次获取的开环调整信息中的第一时延信息，或者，第一调整信息中的星历信息和GNSS信息是上一次获取的开环调整信息中的星历信息和GNSS信息，或者，第一调整信息中的星历信息、GNSS信息和第一时延信息是上一次获取的开环调整信息中的星历信息、GNSS信息和第一时延信息。
基于此，假设第一调整信息中的星历信息是终端设备在第一时刻获取到的，第一调整信息中的GNSS信息是终端设备在第二时刻获取到的，第一调整信息中的第一时延信息是终端设备在第三时刻获取到的，那么，第一调整信息中各个信息的获取时刻包括如下几种情况。
(1)第一时刻是上一次获取开环调整信息中的星历信息的时刻，第二时刻是本次获取开环调整信息中的GNSS信息的时刻，第三时刻是本次获取开环调整信息中的第一时延信息的时刻。
也就是说，第一调整信息中的星历信息是上一次获取的开环调整信息中的星历信息，第一调整信息中的GNSS信息是本次获取的开环调整信息中的GNSS信息，第一调整信息中的第一时延信息是本次获取的开环调整信息中的第一时延信息。那么，终端设备在对定时提前量进行调整时，开环调整所采用的是上一次获取的开环调整信息中的星历信息、本次获取的开环调整信息中的GNSS信息和第一时延信息，闭环调整所采用的是本次获取的闭环调整信息，例如，如图8(a)所示。
