Description

数据传输方法和装置
本申请基于申请号为202011073568.8，申请日为2020年10月09日，申请名称为“数据传输方法和装置”的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及但不限于一种数据传输方法和装置。
背景技术
在非陆地网络(non terrestrial networks，NTN)场景中，用户设备(user equipment，UE)在发送上行数据和/或参考信号时，会基于所获得的定时提前量(timing advance，TA)值进行提前发送，从而补偿电波传输延迟。
例如，在物理下行控制信道(physical downlink control channel，PDCCH)调度物理上行共享信息(physical uplink shared channel，PUSCH)的过程中，PDCCH中的下行控制信息(downlink control information，DCI)会指示UE调度的时延值，协议中将该时延值记为K2；UE根据K2确定PUSCH的发送资源的位置。然而，由于NTN场景中存在较大的传播时延，若UE根据TA值进行提前发送，意味着PDCCH接收时刻与PUSCH发送资源位置之间必须有足够大的时间间隔，因此，PDCCH调度PUSCH的调度时延增强可以为：K2+offset，并通过K2+offset保证PDCCH接收时刻与PUSCH发送时刻之间有足够大的时间间隔，这样可以通过该足够大的时间间隔保证UE进行提前发送。
但是，由于现有的调度时延增强中的offset值是基于最大的来回传播时延值，即卫星处于仰角最小的位置的来回传播时延确定的，是一个固定的值，且为卫星来回传输时的最大传播时延，因此，采用该现有的调度时延增强中的offset值确定调度时延时，会使得调度时延较大，从而导致数据的发送时延较大。

通过上述附图，已示出本公开明确的实施例，后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本公开构思的范围，而是通过参考特定实施例为本领域技术人员说明本公开的概念。
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。
在本申请的实施例中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，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，其中A，B可以是单数或者复数。在本申请的文字描述中，字符“/”一般表示前后关联对象是一种“或”的关系。
本申请实施例提供的数据传输方法可以应用于非陆地网络(non terrestrial networks，NTN)场景中。例如，NTN场景下的定时提前量(timing advance，TA)值提前发送，或者NTN场景下的随机接入过程，可以为随机接入过程中Msg2与Msg3之间；当然，也可以应用于其它类似的场景，在此，本申请实 施例只是以应用于TA值提前发送和随机接入过程为例进行说明，但并不代表本申请实施例仅局限于此。
以应用在TA值提前发送场景为例，在PDCCH调度PUSCH的过程中，PDCCH中的下行控制信息(downlink control information，DCI)会指示UE调度的时延值，协议中将该时延值记为K2；UE根据K2确定PUSCH的发送资源的位置。然而，由于NTN场景中存在较大的传播时延，若UE根据TA值进行提前发送，意味着PDCCH接收时刻与PUSCH发送资源位置之间必须有足够大的时间间隔，因此，PDCCH调度PUSCH的调度时延增强可以为：K2+offset，并通过K2+offset保证PDCCH接收时刻与PUSCH发送时刻之间有足够大的时间间隔，这样可以通过该足够大的时间间隔保证UE进行提前发送。但是，由于现有的调度时延增强中的offset值是基于最大的来回传播时延值，即卫星处于仰角最小的位置的来回传播时延确定的，是一个固定的值，且为卫星来回传输时的最大传播时延，因此，采用该现有的调度时延增强中的offset值确定调度时延时，会使得调度时延较大，从而导致数据的发送时延较大。
为了降低调度时延，从而降低数据的发送时延，可以在PDCCH调度PUSCH的过程中，动态调整调度时延增强中的offset值，使得该offset值不是一直为基于卫星处于仰角最小的位置的来回传播时延确定的最大传播时延，这样可以通过动态调整调度时延增强中的offset值，降低调度时延，从而降低数据的发送时延。由于卫星相对于UE的快速移动(非同步卫星场景)，UE与卫星之间的传播时延会随着时间发生快速的变化，尤其是在地球固定波束(earth-fixed beam)场景下，UE与卫星之间的传播时延会发生巨大的变化，造成UE需要预补偿的TA值(即提前发送的时长)也会发生变化，可参见图1所示，图1为本申请实施例提供的一种应用场景的示意图，因此，可以尝试基于UE与卫星之间的传播时延会随着时间发生快速的变化，动态调整调度时延增强中的offset值，这样可以避免因一直采用基于最大的来回传播时延值确定的offset值导致调度时延较大，降低了调度时延，从而降低了数据的发送时延。
基于上述构思，本申请实施例提供了一种数据传输方法，终端先从网络设备接收更新指示信息；根据更新指示信息，在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值；其中，时间间隔参数的至少两个取值是 根据卫星的运行速度和运行轨道确定的；并根据时间间隔参数的目标取值确定上行发送资源的资源位置；再在资源位置上发送数据；其中，所述数据包括上行数据和/或参考信号。
示例的，在本申请实施例中，更新指示信息可以包括周期间隔、切换指令、或者定时提前量TA调整值中的至少一种。其中，更新间隔可以理解为更新时长。
需要说明的是，在本申请实施例中，根据时间间隔参数的目标取值确定上行发送资源的资源位置，其包含了根据该时间间隔参数的目标取值和DCI指示的调度时延值共同确定上行发送资源的资源位置，而不是仅根据该时间间隔参数的目标取值确定上行发送资源的资源位置。因此，在后续的描述中，根据时间间隔参数的目标取值确定上行发送资源的资源位置，都可以理解为根据该时间间隔参数的目标取值和DCI指示的调度时延值共同确定上行发送资源的资源位置。
可以看出，在本申请实施例中，终端在发送数据时，先从网络设备接收更新指示信息；并根据更新指示信息在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值，由于该更新指示信息和时间间隔参数的至少两个取值都是根据卫星的运行速度和运行轨道动态确定的，这样在根据该动态调整的目标取值确定上行发送资源的资源位置时，该上行发送资源的资源位置也是动态调整的，再在该动态调整的发送资源的资源位置上发送上行数据和/或参考信息，与现有技术中一直采用基于最大的来回传播时延值得到的固定时间间隔参数确定资源位置相比，降低了调度时延，从而降低了数据的发送时延。
其中，1)终端，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备、或车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城 市(smart city)中的无线终端、或智慧家庭(smart home)中的无线终端等。

下面，将分别结合更新指示信息的内容对本申请实施例提供的数据传输方法进行详细的说明。在一种可能的实现方式中，当更新指示信息为更新间隔时，可以根据该更新间隔确定上行发送资源的资源位置，并在该发送资源的位置上发送数据；在另一种可能的实现方式中，当更新指示信息为切换指令时，可以根据该切换指令确定上行发送资源的资源位置，并在该发送资源的位置上发送数据；在又一种可能的实现方式中，当更新指示信息为定时提前量TA调整值时，可以根据该定时提前量TA调整值确定上行发送资源的资源位置，并在该发送资源的位置上发送数据。可以理解的是，在本申请实施例中，下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
在一种可能的实现方式，当更新指示信息为更新间隔时，可以根据该更新间隔在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值，并根据时间间隔参数的目标取值确定上行发送资源的资源位置，再在资源位置上发送数据。示例的，请参见图2所示，图2为本申请实施例提供的一种数据传输方法的流程示意图，该数据传输方法可以由软件和/或硬件装置执行，该数据传输方法可以包括：
S201、网络设备向终端发送更新间隔。
其中，更新间隔是根据卫星的运行速度和运行轨道确定的，随着卫星的运行速度和运行轨道的变化，对应的，更新间隔也会发生变化。示例的，示例的，更新间隔的单位可以是毫秒(ms)，子帧(subframe)，帧(frame)， 时隙(slot)，PDCCH监听周期等，具体可以根据实际需要进行设置，在此，对于更新间隔的具体单位，本申请实施例不做进一步地限制。
示例的，网络设备在向终端发送更新间隔时，可以通过第二消息将该更新间隔发送给终端。其中，第二消息包括广播消息、无线资源控制RRC专用信息、或者媒体访问控制层控制元素MAC CE中的至少一种。
终端在接收到网络设备下发的更新间隔后，根据该更新间隔在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值，即执行下述S202：
S202、终端根据更新间隔，在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值。其中，时间间隔参数的至少两个取值是根据卫星的运行速度和运行轨道确定的。
其中，时间间隔参数的至少两个取值的排列顺序，与卫星运行时的位置变化相关联。
可以理解的是，在本申请实施例中，当终端进行首次时间间隔参数取值的更新时，网络设备需要将该时间间隔参数的至少两个取值发送给终端，这样终端可以将获取到的至少两个取值作为更新依据，对时间间隔参数的取值进行更新。示例的，网络设备在将该时间间隔参数的至少两个取值发送给终端时，可以向终端发送第三消息，该第三消息中包括时间间隔参数对应的集合，集合中包括时间间隔参数的至少两个取值，即可以通过集合的形式将时间间隔参数的至少两个取值携带在第三消息中发送给终端，以使终端获取到该时间间隔参数的至少两个取值。当然，也可以通过表格的形式将时间间隔参数的至少两个取值携带在第三消息中发送给终端，具体可以根据实际需要进行设置，在此，本申请实施例只是以通过集合的形式将时间间隔参数的至少两个取值携带在第三消息中发送给终端为例进行说明，但并不代表本申请实施例仅局限于此。示例的，第三消息包括广播消息和/或无线资源控制RRC专用信息。
以通过集合的形式将时间间隔参数的至少两个取值发送给终端为例，需要说明的是，当终端进行第二次、第三次或者后续的第N次时间间隔参数取值的更新时，在一种场景下，若时间间隔参数的取值范围未发生变化，则网络设备无需将该时间间隔参数对应的集合发送给终端，终端可以继续基于首次时间间隔参数取值的更新时获取到的时间间隔参数对应的集合进行更新，这样可以避免因每次更新均发送时间间隔参数对应的集合而产生的功耗；当 然，若不考虑功耗问题，也可以在终端进行第二次、第三次或者后续的第N次时间间隔参数取值的更新时，通过集合的形式将时间间隔参数的至少两个取值发送给终端。在另一种场景下，若时间间隔参数的取值范围发生变化，即使终端进行第二次、第三次或者后续的第N次时间间隔参数取值的更新，网络设备也需要将该新的时间间隔参数对应的集合发送给终端，这样终端可以基于获取到的新的时间间隔参数对应的集合对时间间隔参数的取值进行更新。
需要说明的是，当网络设备向终端发送时间间隔参数对应的集合和更新间隔时，可以先通过广播消息或者RRC专用信令将时间间隔参数对应的集合发送给终端，再通过广播消息或者RRC专用信令将更新间隔发送给终端，当然，也可以一并通过广播消息或者RRC专用信令将时间间隔参数对应的集合和更新间隔同时发送给终端，具体可以根据实际需要进行设置。
示例的，在根据更新间隔在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值时，可以先从网络设备接收时间间隔参数的当前取值；从当前取值的生效时刻开始，在周期间隔到达时，按照至少两个取值的排列顺序，将时间间隔参数的至少两个取值中当前取值的下一个取值，确定为时间间隔参数的目标取值。需要说明的是，若当前取值为时间间隔参数的初始取值，则可以从网络设备接收第一消息；第一消息中包括时间间隔参数的初始取值的索引，示例的，第一消息包括无线资源控制RRC专用信息，和/或者，媒体访问控制层控制元素MAC CE，这样终端就可以基于该时间间隔参数的初始取值的索引，从该初始取值的生效时刻开始，在周期间隔到达时，将时间间隔参数的初始取值更新为集合中的第二个取值，即集合中初始取值的下一个取值，从而完成时间间隔参数的取值的首次更新。
以时间间隔参数为K_offset为例，假设终端通过接收网络设备的广播消息获取到K_offset对应的集合以及更新间隔，K_offset对应的集合为{K1，K2，K3，K4，K5}，更新间隔为Xms，且MAC CE指示K_offset初始取值的索引为2，则终端从MAC CE指示的K_offset初始取值的生效时刻起，以K_offset的取值K2为起点，每隔Xms，自动将K_offset的取值更新为K_offset对应的集合中的下一个取值，即第一个周期内的K_offset取值为K2，在该周期内，终端根据K2确定上下行定时关系；第二个周期内的K_offset取值为K3，在该周期内，终端根据K3确定上下行定时关系；以此类推。特别地，RAR调 度PUSCH(即Msg3)时，调度时延可以应用网络配置的K_offset取值集合中最大的K_offset取值，即K1。其中，定时关系是指终端根据K_offset取值确定发送上行数据的时机/资源位置，MAC CE的生效时刻以及CSI-RS的资源位置。
可以看出，在该种可能的实现方式中，当更新指示信息为更新间隔时，在整个时间间隔参数更新过程中，网络设备可以仅向终端发送一次更新间隔，终端就可以基于该更新间隔，在每一个更新间隔到达时，自动对时间间隔参数的取值进行更新，这样可以降低网络资源消耗。
在根据更新间隔，在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值后，就可以根据时间间隔参数的目标取值确定上行发送资源的资源位置，即执行下述S203：
S203、终端根据时间间隔参数的目标取值确定上行发送资源的资源位置。
可以理解的是，在本申请实施例中，终端根据时间间隔的目标取值确定上行发送资源的资源位置，包含了终端根据时间间隔的目标取值和DCI指示的调度时延值共同确定上行发送资源的资源位置。
示例的，发送资源的位置可以包括发送上行数据的时机/资源位置，以及上行参考信号发送的时机/资源；其中，上行参考信号可以包括：由DCI触发的非周期的上行探测信号(sounding reference signal，SRS)。
S204、终端在资源位置上发送数据。
其中，数据包括上行数据和/或参考信号。示例的，上行数据可以包括：DCI调度的上行数据，随机接入响应(random access response，RAR)授权调度的上行数据(Msg3)，混合式自动重传请求(hybrid automatic repeat request，RAR))确认(ack)，具体可以根据实际需要进行设置，在此，对于上行数据的内容，本申请实施例不做进一步地限制。
可以看出，在本申请实施例中，终端在发送数据时，先从网络设备接收更新指示信息；并根据更新指示信息在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值，由于该更新指示信息和时间间隔参数的至少两个取值都是根据卫星的运行速度和运行轨道动态确定的，这样在根据该动态调整的目标取值确定上行发送资源的资源位置时，该上行发送资源的资源位置也是动态调整的，再在该动态调整的发送资源的资源位置上发送上行数据和/或参考信息，与现有技术中一直采用基于最大的来回传播时延值得到的固定 时间间隔参数确定资源位置相比，降低了调度时延，从而降低了数据的发送时延。
在另一种可能的实现方式，当更新指示信息为切换指令时，可以根据该切换指令在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值，并根据时间间隔参数的目标取值确定上行发送资源的资源位置，再在资源位置上发送数据。示例的，请参见图3所示，图3为本申请实施例提供的另一种数据传输方法的流程示意图，该数据传输方法可以由软件和/或硬件装置执行，该数据传输方法可以包括：
S301、网络设备向终端发送切换指令。
示例的，网络设备在向终端发送切换指令之前，需要确定切换指令的发送时机，该发送时机是根据卫星的运行速度和运行轨道确定的，随着卫星的运行速度和运行轨道的变化，对应的，时间间隔参数的取值也需要更新，此时网络设备可以向终端发送切换指令。
示例的，网络设备在向终端发送切换指令时，可以通过第二消息将该切换指令发送给终端。其中，第二消息包括广播消息、无线资源控制RRC专用信息、或者媒体访问控制层控制元素MAC CE中的至少一种。
终端在接收到网络设备下发的切换指令后，根据切换指令，在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值，即执行下述S302：
S302、终端根据切换指令，在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值。其中，时间间隔参数的至少两个取值是根据卫星的运行速度和运行轨道确定的。
其中，时间间隔参数的至少两个取值的排列顺序，与卫星运行时的位置变化相关联。
结合上述S202中的描述，在本申请实施例中，当终端进行首次时间间隔参数取值的更新时，网络设备需要将该时间间隔参数的至少两个取值发送给终端，这样终端可以将获取到的至少两个取值作为更新依据，对时间间隔参数的取值进行更新。示例的，网络设备在将该时间间隔参数的至少两个取值发送给终端时，可以向终端发送第三消息，该第三消息中包括时间间隔参数对应的集合，集合中包括时间间隔参数的至少两个取值，即可以通过集合的形式将时间间隔参数的至少两个取值携带在第三消息中发送给终端，以使终端获取到该时间间隔参数的至少两个取值。当然，也可以通过表格的形式将 时间间隔参数的至少两个取值携带在第三消息中发送给终端，具体可以根据实际需要进行设置，在此，本申请实施例只是以通过集合的形式将时间间隔参数的至少两个取值携带在第三消息中发送给终端为例进行说明，但并不代表本申请实施例仅局限于此。示例的，第三消息包括广播消息和/或无线资源控制RRC专用信息。

示例的，在根据切换指令在时间间隔参数的至少两个取值中确定时间间隔参数的目标取值时，可以先可以从网络设备接收时间间隔参数的当前取值；在切换指令生效时，按照至少两个取值的排列顺序，将时间间隔参数的至少两个取值中当前取值的下一个取值，确定为时间间隔参数的目标取值。需要说明的是，若当前取值为时间间隔参数的初始取值，则可以从网络设备接收第一消息；第一消息中包括时间间隔参数的初始取值的索引，示例的，第一消息包括无线资源控制RRC专用信息，和/或者，媒体访问控制层控制元素MAC CE，这样终端就可以基于该时间间隔参数的初始取值的索引，在切换指 令生效时，将时间间隔参数的初始取值更新为集合中的第二个取值，即集合中初始取值的下一个取值，从而完成时间间隔参数的取值的首次更新。
