Description

数据传输方法、芯片、终端及存储介质
本申请要求于2021年01月18日提交中国专利局、申请号为202110062224.5、申请名称为“数据传输方法、芯片、终端及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种数据传输方法、芯片、终端及存储介质。
背景技术
在非陆地网络(Non Terrestrial Networks，NTN)中，终端在发送上行数据时会基于定时提前(Timing Advance，TA)值进行提前发送，以保证上下行链路的同步。例如，在现有的物理下行控制信道(Physical Downlink Control Channel，PDCCH)调度物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的过程中，PDCCH中的下行控制信息(Downlink Control Information，DCI)中会指示终端一个调度的时延值，由此确定PUSCH的发送资源位置。
然而，在卫星通信网络中，由于终端与卫星之间的传输存在较大的传播时延，为了使上下行定时对齐，通常终端需要基于确定的定时提前量进行提前发送。而上述DCI中指示的调度时延值通常设置的较小，无法满足卫星场景中较大的定时提前量的需求，也就是说，基于现有的调度时延，终端无法执行定时提前发送。由此会给终端与卫星之间的时间同步带来问题，进而会降低终端与卫星之间的传输效率。

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。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在NTN中，例如，对于卫星通信网络，一个小区通常可以包含多个波束(Beam)。由于卫星的快速移动，终端需要频繁的进行波束切换。而当一个终端(例如，一个物联网设备)通过上述卫星通信网络接入时，需要有一套波束管理机制来分配通信资源。 然而，当前的物理网协议中没有对应的波束管理机制。
通过对上述问题的研究，发明人发现，物联网中支持载波管理，也就是说，物联网中的通信资源的分配通常以载波为单位。示例性的，在一个物联网网络中，一个单频点小区通常只有180kHZ的带宽，该带宽上除了窄带主同步信号(Narrowband Primary Synchronization Signal，NPSS)、窄带辅同步信号(Narrowband Secondary Synchronization Signal，NSSS)和系统信息块(System Information Block，SIB)外，剩余的业务信道容量很小。因此，为了支持海量终端，需要采用多个频点来提高网络容量。小区内除了包含支持同时承载NPSS、NSSS、窄带物理广播信道(Narrowband Physical Broadcast Channel，NPBCH)、窄带物理下行控制信道(Narrowband Physical Downlink Control Channel，NPDCCH)及窄带物理下行共享信道(Narrowband Physical Downlink Shared Channel，NPDSCH)的锚点载波之外，还可以包含多个只承载NPDCCH及NPDSCH，但不承载NPSS、NSSS及NPBCH的非锚点载波。其中，每个载波的频谱带宽为180kHz，小区内所有载波的最大频谱跨度不超过20MHz。终端可以在非锚点载波上进行数据传输。
因此，可以在载波和波束之间建立映射关系，例如，每个载波对应一个波束，示例性的，载波1对应波束1，载波2对应波束2。由此可以通过载波切换实现波束切换，进而实现波束管理。
然而，网络侧在不同的波束之间切换时，终端与卫星之间的传输时延是不同的。目前，网络侧仅考虑了调度时延，没有考虑上述终端与卫星之间的传输时延，由此会给终端与卫星之间的时间同步带来问题，进而影响到终端与卫星之间的传输效率。
基于上述问题，本申请实施例提出了一种数据传输方法。
现结合图1-图10对本申请实施例提供的数据传输方法进行说明。图1为本申请实施例提供的应用场景，参考图1，上述应用场景包括终端100及卫星200。可以理解的是，卫星200为网络侧的设备，并不构成对本申请实施例的限定，在一些实施例中，该网络侧的设备也可以以其他形式体现。

图2为本申请提供的数据传输方法一个实施例的流程示意图，包括：
步骤101，卫星200发送定时偏移配置信息。
具体地，卫星200可以通过广播方式发送定时偏移配置信息。示例性的，卫星200可以通过NPBCH对系统广播消息(例如，SIB)进行广播，该SIB中可以携带上述定时偏移配置信息。其中，该定时偏移配置信息可以包含多个定时偏移，每个定时偏移可以和一个上行载波对应。可以理解的是，由于每个上行载波与一个波束对应，因此，每个上行载波的定时偏移也可以与一个波束对应，由此可以实现不同的上行载波或波束可以对应不同的定时偏移。表1为定时偏移配置信息表，如表1所示，该定时偏移配置信息表可以包括上行载波、波束与定时偏移之间的映射关系。
表1
上行载波ID 波束ID 定时偏移
上行载波1 波束1 T_offset1
上行载波2 波束2 T_offset2
… … …
可以理解的是，上述表1仅示例性的示出了上行载波、波束与定时偏移之间的映射关系，并不构成对本申请实施例的限定。在一些实施例中，定时偏移配置信息也可以包含上行载波与定时偏移之间的映射关系或波束与定时偏移之间的映射关系，其中，上行载波与波束之间的映射关系可以预先在终端100中进行配置。
需要说明的是，每个上行载波的定时偏移可以由终端100与卫星200之间的传输时延确定。
此外，上述表1仅示例性的通过ID方式表征上行载波的身份标识，并不构成对本申请实施例的限定，在一些实施例中，也可以通过索引(index)方式对上行载波进行身份标识。
可选地，卫星200还可以通过RRC专用信令发送上述定时偏移配置信息。示例性的，当终端100与卫星200之间建立RRC连接后，卫星200可以向终端100发送RRC专用信令，该RRC专用信令中可以携带上述定时偏移配置信息。具体的RRC专用信令可以参考3GPP相关协议，在此不再赘述。
步骤102，终端100接收卫星200发送的定时偏移配置信息，并进行存储。
步骤103，卫星200准备由第一波束切换至第二波束，通过第一波束向终端100发送第二载波的ID。
具体地，由于卫星200的快速移动，会导致卫星200与终端100之间使用的波束发生频繁的切换，因此，卫星200可以通过下行消息通知切换后的目标波束。在具体实现时，该下行消息可以是DCI或随机接入响应授予(Random Access Response Grant， RAR Grant)，该第一波束可以是卫星200的波束资源中的任意一个波束，该第一波束可以是切换前的波束，例如，该第一波束可以是表1中的波束1。该第一波束与第一载波对应，该第一载波可以是终端100的载波资源中的其中一个载波，例如，该第一载波可以是表1中的载波1。该第二波束可以是卫星200的波束资源中的另一个波束，该第二波束可以是切换后的目标波束。例如，该第二波束可以是表1中的波束2。该第二波束与第二载波对应，该第二载波可以是终端100的载波资源中的另一个载波，例如，该第二载波可以是表1中的载波2。
示例性的，卫星200可以通过该第一波束所在的PDCCH发送DCI，或者通过随机接入(Random Access，RA)过程发送RAR Grant，具体的RA过程可以参考3GPP相关协议，在此不再赘述。其中，该DCI或RAR Grant可以包括第二载波的ID。
可选地，该DCI或RAR Grant中还可以包括调度时延。
可以理解的是，上述示例仅示例性示出了上述下行消息(例如，DCI或RAR Grant)中包含第二载波的ID的方式，并不构成对本申请实施例的限定，在一些实施例中，由于上行载波与波束之间具有映射关系，因此，上述第二载波的ID也可以用第二波束的ID替代。
步骤104，终端100接收卫星200发送的第二载波的ID，基于第二载波的ID确定数据传输时刻。
具体地，由于卫星200通过第一波束发送上述DCI或RAR Grant，基于上行载波与波束之间的映射关系，终端100可以通过第一载波接收上述DCI或RAR Grant。当终端100接收到卫星200发送的DCI或RAR Grant后，可以获取上述DCI或RAR Grant中的调度时延以及第二载波的ID。
接着，可以基于第二载波的ID在已存储的定时偏移配置信息中查询，得到与该第二载波对应的定时偏移(例如，T_offset2)。当获取到第二载波的定时偏移后，可以基于上述调度时延及第二载波的定时偏移确定数据传输时刻。示例性的，数据传输时刻T＝T_start+T0+T_offset2，其中，T_start为起始时刻，T0为上述调度时延。
可选地，由于在载波切换过程中，还会存在载波切换时延，因此，在计算上述数据传输时刻T时，还可以考虑载波切换时延。示例性的，数据传输时刻T＝T_start+T0+T_offset2+T1，其中，T1为载波切换时延。
现以DCI为例进行说明，如图3所示，卫星200通过第一波束所在的PDCCH向终端100发送DCI，基于上行载波与波束之间的映射关系，终端100通过第一载波接收卫星200发送的DCI。终端100完整接收上述DCI的时刻为T_start。当终端100完整接收上述DCI后，可以获取上述DCI中的调度时延T0及第二载波的定时偏移T_offset2，并可以在T_start+T0+T_offset2时刻发送数据。例如，可以在T_start+T0+T_offset2时刻通过第二载波所在的PUSCH发送数据。
可选地，当获取到第二载波的定时偏移T_offset2后，还可以进一步获取第一载波的定时偏移T_offset1。此时，可以将上述T_offset1与T_offset2进行比较。
若T_offset1>＝T_offset2，则数据传输时刻T＝T_start+T0+T_offset1；
若T_offset1<＝T_offset2，则数据传输时刻T＝T_start+T0+T_offset2。
可以理解的是，图3仅示例性的示出了DCI的场景，并不构成对本申请实施例的 限定。在一些实施例中，也可以通过RAR Grant的方式确定数据传输时刻。
步骤105，终端100基于上述数据传输时刻向卫星200发送数据。
具体地，当终端100确定数据传输时刻后，可以在上述数据传输时刻使用第二载波所在的PUSCH向卫星200发送数据。
本申请实施例中，通过网络侧基于每个波束配置传输时延，在网络侧切换至目标载波时，终端侧基于目标载波确定对应的传输时延，并基于该传输时延确定数据传输时刻，由此可以实现终端侧与网络侧的时间同步，进而可以提高终端侧与网络侧的传输效率。
图4为本申请提供的数据传输方法另一个实施例的流程示意图，包括：
步骤201，卫星200发送定时偏移集合配置信息。
具体地，卫星200可以通过广播方式发送定时偏移集合配置信息。示例性的，卫星200可以通过NPBCH对系统广播消息(例如，SIB)进行广播，该SIB中可以携带上述定时偏移集合配置信息。其中，该定时偏移集合配置信息可以包含多个定时偏移集合，每个定时偏移集合可以和一个上行载波对应，每个定时偏移集合可以包括多个定时偏移。可以理解的是，由于每个上行载波与一个波束对应，因此，每个上行载波的定时偏移集合也可以与一个波束对应，由此可以实现不同的上行载波或波束可以对应不同的定时偏移。表2为定时偏移集合配置信息表，如表2所示，该定时偏移集合配置信息表可以包括上行载波、波束与定时偏移集合之间的映射关系。
表2
上行载波ID 波束ID 定时偏移集合
上行载波1 波束1 T_offset11，T_offset12
上行载波2 波束2 T_offset21，T_offset22
… … …
可以理解的是，上述表2仅示例性的示出了定时偏移集合中定时偏移的数量，并不构成对本申请实施例的限定。在一些实施例中，每个定时偏移集合还可以包括3个或更多的定时偏移。
可选地，卫星200还可以通过RRC专用信令发送上述定时偏移集合配置信息。示例性的，当终端100与卫星200之间建立RRC连接后，卫星200可以向终端100发送RRC专用信令，该RRC专用信令中可以携带上述定时偏移集合配置信息。
步骤202，终端100接收卫星200发送的定时偏移集合配置信息，并进行存储。
步骤203，卫星200准备由第一波束切换至第二波束，通过第一波束向终端100发送第二载波的ID及索引标识。
具体地，卫星200可以向终端100发送第二载波的ID及索引标识，其中，该第二载波的ID及索引标识可以通过DCI或RAR Grant携带。该索引标识用于表征定时偏移集合中的定时偏移的索引。在具体实现时，上述索引标识可以通过DCI或RAR Grant中的特殊域指示。示例性的，若定时偏移集合包括2个定时偏移，则该特殊域可以包括1个bit(例如，该索引标识可以为0或1)。以上行载波1为例，若索引标识为“0”则可以指示第一个定时偏移(例如，T_offset11)；若索引标识为“1”，则可以指示第二个定时偏移(例如，T_offset12)。
可选地，上述DCI或RAR Grant中还可以携带调度时延。
步骤204，终端100接收卫星200发送的第二载波的ID及索引标识，基于第二载波的ID及索引标识确定数据传输时刻。
具体地，由于卫星200通过第一波束发送上述DCI或RAR Grant，基于上行载波与波束之间的映射关系，终端100可以通过第一载波接收上述DCI或RAR Grant。当终端100接收到卫星200发送的DCI或RAR Grant后，可以获取上述DCI或RAR Grant中的调度时延、第二载波的ID以及索引标识。
接着，可以基于由第二载波的ID在定时偏移集合配置信息查询，得到与该第二载波对应的定时偏移集合。当获取到第二载波的定时偏移集合后，可以基于上述索引标识确定定时偏移集合中的定时偏移(例如，该定时偏移可以是第二载波的定时偏移集合中的T_offset21或T_offset22)，并可以基于调度时延及确定的第二载波的定时偏移确定数据传输时刻。示例性的，若确定第二载波的定时偏移集合中的定时偏移为T_offset21，则数据传输时刻T＝T_start+T0+T_offset21。
可选地，由于在载波切换过程中，还会存在载波切换时延，因此，在计算上述数据传输时刻T时，还可以考虑载波切换时延。示例性的，数据传输时刻T＝T_start+T0+T_offset21+T1，其中T1为载波切换时延。
步骤205，终端100基于上述数据传输时刻向卫星200发送数据。
具体地，当终端100确定数据传输时刻后，可以在上述数据传输时刻使用第二载波所在的PUSCH向卫星200发送数据。
本申请实施例中，通过网络侧基于每个波束配置传输时延集合，在网络侧切换至目标载波时，可以在传输时延集合中选取任意一个传输时延，终端侧基于网络侧指示的传输时延确定发送时刻，由此可以提高传输时延选取的灵活性，并可以实现终端侧与网络侧的时间同步，进而可以提高终端侧与网络侧的传输效率。

可选地，卫星200还可以通过RRC专用信令发送上述定时偏移配置信息。示例性的，当终端100与卫星200之间建立RRC连接后，卫星200可以向终端100发送RRC专用信令，该RRC专用信令中可以携带上述定时偏移配置信息。
步骤302，终端100接收卫星200发送的定时偏移配置信息，并进行存储。
步骤303，卫星200通过第一波束向终端100发送指示信息，指示终端100对本次调度的一个传输块进行分段传输。
具体地，为了提高波束之间的利用效率，卫星200可以将本次调度的传输块进行分段后，分别在两个波束上传输(例如，可以在第一波束和第二波束上传输)。在具体实现时，卫星200可以向终端100发送指示信息，该指示信息可以通过DCI或RAR Grant承载。其中，该指示信息可以包括调度时延、第二载波的ID以及数据分割信息，该数据分割信息用于指示本次调度的传输块的分割情况以及分割后的传输块与上行载波的对应情况。表3为数据分割信息的示例表。
表3
Figure PCTCN2022076412-appb-000001
如表3所示，数据分割信息可以包括数据标识域及载波ID域，其中，数据标识域用于标识对传输块的分割方式，例如，假设一个传输块(Transport Block，TB)为1024字节，若对该传输块进行分割，分别得到长度为400字节的第一数据分段(例如，首字节为0以及尾字节为399)以及长度为624字节的第二数据分段(例如，首字节为400，尾字节为1023)。其中，第一数据分段与上行载波1对应，也就是说，终端100可以使用第一载波(例如，该第一载波可以是表3中的上行载波1，该上行载波1与第一波束对应)传输该第一数据分段；而第二数据分段与上行载波2对应，也就是说，终端100可以使用第二载波(例如，该第二载波可以是表3中的上行载波2，上行载波2与第二波束对应)传输该第二数据分段。
可以理解的是，上述表3仅示例性的示出了通过上述相关的域对数据进行分割的方式，并不构成对本申请实施例的限定，在一些实施例中，该数据分割信息也可以包括更多或更少的域。

若T_offset1>＝T_offset2，则第一数据分段的数据传输时刻T_1＝T_start+T0+T_offset1(为说明方便，下文将“第一数据分段的数据传输时刻”简称为“第一时刻”)，第二数据分段的数据传输时刻T_2＝T_start+T0+T_offset1+T1+T2(为说明方便，下文将“第二数据分段的数据传输时刻”简称为“第二时刻”)；其中，T_start为起始时 刻，T0为上述调度时延，T1为载波切换时延，T2为第一数据分段的传输时长。该第一数据分段的传输时长T2可以包括首次传输以及重传该第一数据分段的累计时长，其中，该重传的次数可以预先配置(例如，上行重传最大次数可以配置为128次)。
若T_offset1<＝T_offset2，则第一时刻T_1＝T_start+T0+T_offset2，第二时刻T_2＝T_start+T0+T_offset2+T1+T2。
现结合图6进行说明，如图6所示，卫星200通过第一波束所在的PDCCH向终端100发送DCI，指示本次调度的传输块分成两个数据分段(例如，第一数据分段以及第二数据分段)，分别在与第一波束对应的第一载波和与第二波束对应的第二载波上传输。终端100在完整接收到卫星200发送的DCI后，确定起始时刻T_start，计算出第二载波的定时偏移T_offset2，并将该第二载波的定时偏移T_offset2与第一载波的定时偏移T_offset1进行比较。假设T_offset1>＝T_offset2，则终端100确定上述第一时刻T_1＝T_start+T0+T_offset1，其中，T0为DCI中指示的调度时延。接着，假设传输(例如，包括首次传输及重传)该第一数据分段的累计时长为T2，则终端100可以确定上述第二时刻T_2＝T_start+T0+T_offset1+T1+T2，其中，T1为载波切换时延。
