与现有技术相比，本发明实施例的技术方案具有以下有益效果：
对于UE侧，本发明实施例提供一种数据传输方法，包括：获取预配置下行资源的配置信息，以确定所述预配置下行资源的资源位置；处于空闲态或非激活态期间，在所述预配置下行资源直接接收下行数据；其中，直接接收是指在不切换至RRC连接态的前提下进行数据接收。

具体实施方式
如背景技术所言，现有的终端设备(也称用户设备，User Equipment，简称UE)必须发起随机接入过程切换至RRC连接态后才能接收下行数据，造成较大的RRC信令开销以及较大的终端设备能耗，同时也会造成不必要的下行数据传输时延。
为解决上述技术问题，本发明实施例提供一种数据传输方法，包括：获取预配置下行资源的配置信息，以确定所述预配置下行资源的 资源位置；处于空闲态或非激活态期间，在所述预配置下行资源直接接收下行数据；其中，直接接收是指在不切换至RRC连接态的前提下进行数据接收。
本实施方案使得UE无需发起随机接入进入连接态即能接收数据，利于减少信令开销、节省资源并降低设备能耗，且能够减少不必要的下行数据传输时延。具体而言，在空闲态或非激活态引入周期性的预配置下行资源，UE能够在所述预配置下行资源上直接接收下行数据，从而避免UE发起随机接入过程进入RRC连接态。由于直接在预配置下行资源接收下行数据，使得下行数据的传输时延得到有效减少，且UE无需与网络进行信令交互来切换状态和请求调度资源，使得减少信令开销、节省资源、降低设备能耗和减少下行数据传输时延成为可能。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明第一实施例一种数据传输方法的流程图。
本实施方案可以由用户设备侧执行，如由UE执行。在具体实施中，下述步骤S101～步骤S102所提供的数据传输方法可以由用户设备中的具有数据传输功能的芯片执行，也可以由用户设备中的基带芯片执行。
本实施方案可以应用于2G、3G、5G或未来通信系统的应用场景。
具体地，参考图1，本实施例所述数据传输方法可以包括如下步骤：
步骤S101，获取预配置下行资源的配置信息，以确定所述预配置下行资源的资源位置；
步骤S102，处于空闲态或非激活态期间，在所述预配置下行资源直接接收下行数据；
其中，直接接收是指在不切换至RRC连接态的前提下进行数据接收。
在一个具体实施中，所述步骤S101可以是在所述UE处于RRC连接态时执行的，所述步骤S102则是在所述UE从RRC连接态切换至空闲态或非激活态时执行的。
具体地，所述预配置下行资源的配置信息可以是通过RRC信令承载的。
例如，所述步骤S101可以包括步骤：处于RRC连接态期间接收RRC信令；从所述RRC信令中获取所述预配置下行资源的配置信息。
在一个具体实施中，所述预配置下行资源可以是周期性重复的，如图2所示。
具体地，所述预配置下行资源的配置信息可以包括：所述预配置下行资源的周期和起始位置。其中，所述起始位置是指配置给所述UE的周期性重复的预配置下行资源中第一个预配置下行资源的时频位置；所述周期是指相邻两个预配置下行资源之间的时间间隔。
进一步，根据所述预配置下行资源的配置信息，可以确定周期性重复的各预配置下行资源的时频位置。
在一个具体实施中，不同UE可以配置不同的预配置下行资源，其中，所述不同的预配置下行资源可以在时频域上区分开，也可以是在时域上对应同一个资源但通过空分、码分等形式区分开。
例如，网络可以针对与其建立RRC连接的各个UE分别配置不同的预配置下行资源，并将各UE的预配置下行资源的配置信息通过各RRC信令发送给各UE。
在一个具体实施中，响应于接收到所述预配置下行资源的配置信息，所述UE可以据此确定配置给自己的预配置下行资源的资源位置，并在未来切换至空闲态或非激活态后在预配置下行资源的资源位置 上接收网络发送给自己的下行数据。在接收下行数据期间，UE无需发起随机接入过程，也无需切换至RRC连接态。
在一个具体实施中，所述步骤S102可以包括步骤：接收指示信息，其中，所述指示信息用于指示后续第一数量的预配置下行资源激活或去激活；在激活的后续第一数量的预配置下行资源直接接收下行数据。
具体地，所述指示信息可以通过公共下行控制信息(Downlink Control Information，简称DCI)、专用DCI和/或寻呼消息承载。
进一步，所述指示信息可以包括多个比特位，所述多个比特位与多个UE一一对应，或者，多个比特位中的部分比特位对应同一UE，各比特位用于指示配置给对应UE的后续第一数量的预配置下行资源激活或去激活。以所述指示信息通过公共DCI承载为例，由于所述公共DCI可能发送至多个UE，因此，由公共DCI承载的指示信息可以分别指示分配给多个UE的后续预配置下行资源是否可用。由此，只需发送一个指示信息就可以使得多个UE获知后续是否能够使用预配置下行资源接收下行数据，利于降低信令开销。
进一步，所述预配置下行资源的配置信息可以包括所述第一数量的候选值集合，所述指示信息指示的第一数量选自所述候选值集合。由此，可以根据实际情况动态调整激活或释放的预配置下行资源的数量，以更好的节省资源。
在一个具体实施中，所述UE可以通过接收网络(或控制节点)下发的所述公共DCI(common DCI)来确定后续第一数量的预配置下行资源是否可用。
具体而言，公共DCI是指小区内所有UE或者小区内一组UE均可以接收到的DCI控制信息。进一步，所述公共DCI相关的传输参数配置是通过广播消息或者RRC专用信令下发给UE的。
进一步，网络可以通过公共DCI指示配置了预配置下行资源的 UE后续第一数量的预配置下行资源是否可用(即是否激活)。
例如，可以在公共DCI中增设专门的比特域用于激活或去激活配置了预配置下行资源的UE后续第一数量的预配置下行资源。
进一步，每个配置了预配置下行资源的终端设备在公共DCI中均对应一个比特(bit)位。网络在给UE配置预配置下行资源时会指示该UE在公共DCI中对应的比特位。相应的，UE在空闲态或非激活态下，通过其在公共DCI对应的比特位的取值确定后续第一数量的预配置下行资源是否可用(即是否被激活)。
例如，当对应的比特位取值为0时，则UE确定后续第一数量的预配置下行资源是不可用的。又例如，当对应的比特位取值为1时，则UE确定后续第一数量的预配置下行资源是可用的。
进一步，公共DCI中对应的比特位的具体数值与后续第一数量的预配置下行资源是否激活的对应关系，可以预先通过RRC信令指示。
进一步，所述UE在公共DCI中对应的比特位可以基于公式UE ID mod x计算确定，其中，UE ID为UE的身份标识(Identification，简称ID)，mod表示取余运算，x为网络预先指示的数值，x可以包含于预配置下行资源的配置信息。上述公式也可以写成mod(UE ID,x)，其中mod()表示对括号里的内容取余。各个UE根据自己的UE ID和网络指示的x可以确定在公共DCI上对应的比特位。网络指示给不同UE的x的具体数值可以相同也可以不同。
进一步，所述第一数量可以包含于预配置下行资源的配置信息并通过RRC信令预先指示给UE。
例如，当对应的比特位取值为0时，则UE确定后续的m个预配置下行资源是不可用的。又例如，当对应的比特位取值为1时，则UE确定后续的m个预配置下行资源是可用的。其中，m为所述第一数量。
进一步，所述后续第一数量的预配置下行资源可以是从接收到公共DCI起算的第一数量的预配置下行资源。例如，参考图2，假设t0时刻接收到公共DCI且第一数量为2，则图示位于t0时刻之后的两个预配置下行资源激活或去激活。
进一步，不同UE被配置的第一数量可以相同也可以不同。
进一步，公共DCI中增设的比特域可以使用公共DCI中的预留比特。
在一个变化例中，第一数量也可以是通过公共DCI动态指示的，也即，可以在公共DCI中指示各个UE在接下来特定数量个预配置下行资源激活或去激活。由此，系统对资源的利用灵活性更大。
在一个具体实施中，所述UE可以通过接收网络(或控制节点)下发的专用DCI来确定后续第一数量的预配置下行资源是否可用。
具体而言，UE级别(即UE专用)的DCI是指只能由某个特定的UE才能接收的DCI。进一步，所述专用DCI相关的传输参数配置是通过RRC专用信令配置给UE的。
进一步，网络可以通过专用DCI指示配置了预配置下行资源的UE后续第一数量的预配置下行资源是否可用(即是否激活)。
例如，可以在专用DCI中增设一个特定的比特用于激活或去激活配置了预配置下行资源的UE后续第一数量的预配置下行资源。
进一步，UE在接收到专用DCI后，根据所述专用DCI中对应的比特位的取值确定后续第一数量的预配置下行资源是否可用(即是否被激活)。
例如，当对应的比特位取值为0时，则UE确定后续第一数量的预配置下行资源是不可用的。又例如，当对应的比特位取值为1时，则UE确定后续第一数量的预配置下行资源是可用的。
进一步，网络在给UE配置所述预配置下行资源时可以给UE配 置多个数值作为所述第一数量的候选取值。进一步，网络可以在专用DCI中指示本次指示激活或去激活的预配置下行资源的第一数量取自多个候选值中的哪一个。
例如，假设专用DCI中存在2个比特位用于预配置下行资源的激活和去激活，网络配置的第一数量的候选值集合为{2,4,6}。则当对应的比特位取值为00时，则UE确定后续2个预配置下行资源是不可用的；当对应的比特位取值为01时，则UE确定后续2个预配置下行资源是可用的；当对应的比特位取值为10时，则UE确定后续4个预配置下行资源是可用的；当对应的比特位取值为11时，则UE确定后续6个预配置下行资源是可用的。
进一步，专用DCI中对应的比特位的具体数值与第一数量以及所述第一数量的预配置下行资源是否激活的对应关系，可以预先通过RRC信令指示。
进一步，不同UE被配置的第一数量的候选值集合可以相同、部分相同或完全不同。
进一步，专用DCI中增设的比特位可以使用专用DCI中的预留比特。
当所述预配置下行资源的配置信息包括所述第一数量的候选值集合时，则每一UE在承载所述指示信息的专用DCI中可以对应一个比特块，所述比特块包含多个比特。
在本实施例中，预配置下行资源激活是指预配置下行资源是可用的，也即，网络在所述预配置下行资源激活发送下行数据，UE也可以在所述预配置下行资源激活接收所述下行数据。
相应的，预配置下行资源去激活是指预配置下行资源是不可用的，也即，网络不会在所述预配置下行资源激活发送下行数据，UE也暂停在所述预配置下行资源激活接收所述下行数据。
进一步，当预配置下行资源去激活时，所述预配置下行资源可以 被网络释放并被分配给其他UE或用于其他用途。
在一个具体实施中，所述UE可以通过接收网络发送的寻呼(paging)消息来确定后续第一数量的预配置下行资源是否可用。
具体而言，所述寻呼消息的作用可以包括：(1)向处于RRC连接态的UE发送呼叫请求；(2)通知处于RRC空闲态、RRC非激活态和RRC连接态的UE系统信息发生了变化；(3)地震海啸通知，用于指示UE开始接收地震海啸预警系统(Earthquake and Tsunami Warning System，简称ETWS)主要(primary)通知和/或ETWS次要(secondary)通知，指示UE开始接收商用移动预警系统，简称(Commercial Mobile Alert System，简称CMAS)通知。如果有UE被寻呼、系统信息发生更新或发生地震海啸，则基站先发送唤醒信号，UE检测到唤醒信号后，去监听寻呼的物理下行控制信号(Physical Downlink Control Channel，简称PDCCH)以接收寻呼消息；否则，UE将一直保持睡眠状态以达到省电的目的。在新无线(New Radio，简称NR)系统中，UE可以在RRC空闲态和RRC非激活态中使用不连续接收(Discontinuous Reception，简称DRX)以便降低功耗。UE可以周期性(如周期可以为DRX周期)监听寻呼时刻(Paging occasion，简称PO)。
进一步，可以在寻呼消息中设置专门的字段用于指示UE后续第一数量的预配置下行资源是否可用。相应的，UE在空闲态或非激活态下，可以通过接收寻呼消息来确定后续第一数量的预配置下行资源是否可用(即是否被激活)。
进一步，所述第一数量可以通过预配置下行资源的配置信息指示给UE。
进一步，所述预配置下行资源的配置信息可以包括所述第一数量的候选值集合，所述UE通过所述寻呼消息中对应的比特位的具体数值确定第一数量的具体数值，以及该第一数量的预配置下行资源是否激活。
在一个具体实施中，所述步骤S102可以包括步骤：若在所述预配置下行资源正确接收到所述下行数据并反馈ACK，则启动定时器；将所述定时器超时之前的预配置下行资源确定为去激活状态。
具体地，所述正确接收是指成功接收到下行数据并解码成功。
进一步，在接收到下行数据后，UE可以向网络发送混合自动重传请求(Hybrid Automatic Repeat reQuest，简称HARQ)确认或否定确认(ACKnowledgement/Non-ACKnowledgement，简称ACK/NACK)消息。其中，ACK表明UE正确接收到下行数据，NACK表明UE没能正确接收所述下行数据。
进一步，所述定时器的具体数值可以通过预配置下行资源的配置信息预先指示给UE。
进一步，所述定时器的时间粒度可以选自：毫秒、子帧、帧、时隙以及预配置下行资源的周期。
在本具体实施中，处于空闲态或非激活态的UE可以自第一个预配置下行资源起在网络配置的各个预配置下行资源接收下行数据。当在某个预配置下行资源正确接收到下行数据并反馈ACK后，UE启动所述定时器。进一步，在所述定时器超时之前，位于正确接收到下行数据的预配置下行资源之后的预配置下行资源都是不可用的。
在一个具体实施中，在所述步骤S102之后，本实施例所述数据传输方法还可以包括步骤：在预配置上行反馈资源发送指向所述下行数据的接收反馈信息。
具体地，网络可以在通过RRC信令为UE配置预配置下行资源的同时也为UE配置相应的预配置上行反馈资源。
在一个具体实施中，所述预配置上行反馈资源可以与预配置下行资源一一对应。也即，每个预配置下行资源均关联一个预配置上行反馈资源，如图3所示。
进一步，预配置下行资源与关联的预配置上行反馈资源之间可以存在固定的时间间隔(offset，也可称为偏移量)，所述时间间隔的具体数值可以由RRC信令配置。也即，所述预配置下行资源的配置信息可以包括：与所述预配置下行资源相关联的预配置上行反馈资源相对于所述预配置下行资源的时间间隔。
进一步，UE可以根据预配置下行资源的资源位置以及所述时间间隔确定每个预配置下行资源对应的预配置上行反馈资源。
进一步，当UE在某个预配置下行资源接收到下行数据后，可以在该预配置下行资源关联的预配置上行反馈资源发送指向所述下行数据的接收反馈信息。其中，所述接收反馈信息用于指示是否成功接收到所述下行数据，也即，所述接收反馈信息为ACK或NACK。
例如，参考图3，假设t1时刻UE在预配置下行资源接收到下行数据并解码成功，则可以在t1时刻的预配置下行资源关联的t2时刻的预配置上行反馈资源发送ACK至网络。
在一个变化例中，不同的预配置下行资源与其关联的预配置上行反馈资源之间的时间间隔可以是相同的，也可以是不同的。
在一个具体实施中，所述预配置上行反馈资源可以与多个预配置下行资源相关联。也即，网络可以配置每N个预配置下行资源关联一个预配置上行反馈资源。N为大于等于2的整数。
相应的，在每N个预配置下行资源上的下行数据对应的ACK或NACK反馈均通过同一个预配置上行反馈资源发送给网络。其中，参数N可以由RRC信令配置。
进一步，每N个预配置下行资源中第N个预配置下行资源与预配置上行反馈资源之间可以存在固定的时间间隔(offset)，所述时间间隔的具体数值可以由RRC信令配置。
进一步，UE可以根据第N个预配置下行资源的资源位置以及所述时间间隔确定每N个预配置下行资源对应的预配置上行反馈资源。
进一步，当UE在某个预配置下行资源接收到下行数据后，可以在该预配置下行资源关联的预配置上行反馈资源发送指向所述下行数据的接收反馈信息。其中，所述接收反馈信息用于指示是否成功接收到所述下行数据，也即，所述接收反馈信息为ACK或NACK。
例如，参考图4，假设网络配置给UE总共N+N’个预配置下行资源，其中前面每N个预配置下行资源关联一个预配置上行反馈资源，后面每N’个预配置下行资源关联一个预配置上行反馈资源。当UE在时刻t3和时刻t4接收到下行数据时，可以根据接收情况在这两个时刻的预配置下行资源关联的预配置上行反馈资源(图4所示示例中为同一个资源，即t5时刻的预配置上行反馈资源)发送ACK或NACK。
在一个变化例中，不同的N个预配置下行资源与关联的预配置上行反馈资源之间的时间间隔可以相同也可以不同。
在一个变化例中，不同预配置上行反馈资源关联的预配置下行资源的具体数值可以相同也可以不同。
在一个具体实施中，所述预配置下行资源的配置信息可以包括：所述预配置上行反馈资源的周期和起始位置。
也即，与预配置下行资源相类似，所述预配置上行反馈资源也是周期性重复的。相应的，网络在通过RRC专用信令配置周期性重复的预配置下行资源的同时，也会配置周期性重复的预配置上行反馈资源。
进一步，预配置上行反馈资源的周期的粒度可以选自：预配置下行资源的周期、子帧、毫秒、帧以及时隙。也即，预配置上行反馈资源的周期可以等于预设数量个预配置下行资源的周期。或者，所述预配置上行反馈资源的周期的粒度可以是预设数量个子帧、毫秒、帧或时隙。
进一步，在所述步骤S102之后，本实施例所述数据传输方法还 可以包括步骤：确定与接收到所述下行数据的预配置下行资源最接近的预配置上行反馈资源；在确定的所述预配置上行反馈资源发送指向所述下行数据的接收反馈信息。
具体而言，每个预配置上行反馈资源周期内的预配置下行资源均关联当前周期的上行反馈资源。也即，UE在接收到下行数据后的最近一个预配置上行反馈资源发送接收反馈信息。
进一步，UE可以根据周期性的预配置下行资源以及周期性的预配置上行反馈资源确定每个预配置下行资源关联的上行反馈资源。
参考图5，根据预配置下行资源的周期1和起始位置以及预配置上行反馈资源的周期2和起始位置，可以确定各预配置下行资源和预配置上行反馈资源的资源位置。进一步，可以确定图5中预配置下行资源51和预配置下行资源52关联预配置上行反馈资源53，预配置下行资源54和预配置下行资源55关联预配置上行反馈资源56。
由上，采用本实施方案，使得UE无需发起随机接入进入连接态即能接收数据，利于减少信令开销、节省资源并降低设备能耗，且能够减少不必要的下行数据传输时延。具体而言，在空闲态或非激活态引入周期性的预配置下行资源，UE能够在所述预配置下行资源上直接接收下行数据，从而避免UE发起随机接入过程进入RRC连接态。由于直接在预配置下行资源接收下行数据，使得下行数据的传输时延得到有效减少，且UE无需与网络进行信令交互来切换状态和请求调度资源，使得减少信令开销、节省资源、降低设备能耗和减少下行数据传输时延成为可能。

具体地，参考图6，本实施例所述数据传输装置6可以包括：获取模块61，用于获取预配置下行资源的配置信息，以确定所述预配 置下行资源的资源位置；直接接收模块62，处于空闲态或非激活态期间，在所述预配置下行资源直接接收下行数据；其中，直接接收是指在不切换至RRC连接态的前提下进行数据接收。
关于所述数据传输装置6的工作原理、工作方式的更多内容，可以参照上述图1至图5中的相关描述，这里不再赘述。
在具体实施中，上述的数据传输装置6可以对应于用户设备中具有数据传输功能的芯片，或者对应于具有数据处理功能的芯片，例如片上系统(System-On-a-Chip，简称SOC)、基带芯片等；或者对应于用户设备中包括具有数据传输功能芯片的芯片模组；或者对应于具有数据处理功能芯片的芯片模组，或者对应于用户设备。
图7是本发明第三实施例一种数据传输方法的流程图。

具体地，参考图7，本实施例所述数据传输方法可以包括如下步骤：
步骤S701，发送预配置下行资源的配置信息；
步骤S702，在所述预配置下行资源发送下行数据；
其中，发送所述下行数据期间与接收所述下行数据的UE未建立RRC连接。
本领域技术人员理解，所述步骤S701和步骤S702可以视为与上述图1所示实施例所述步骤S101和步骤S102相呼应的执行步骤，两者在具体的实现原理和逻辑上是相辅相成的。因而，本实施例中涉及名词的解释可以参考图1所示实施例的相关描述，这里不再赘述。
具体而言，所述步骤S701可以是在与UE建立RRC连接期间执 行的。具体地，通过RRC专用信令发送所述预配置下行资源的配置信息至UE。
进一步，所述步骤S702可以是在与UE断开RRC连接后执行的。在执行步骤S702之间，UE处于空闲态或非激活态。
在一个具体实施中，所述步骤S702可以包括步骤：发送指示信息，其中，所述指示信息用于指示后续第一数量的预配置下行资源激活或去激活；在指示激活的后续第一数量的预配置下行资源发送所述下行数据。
进一步，所述指示信息可以通过公共DCI、专用DCI和/或寻呼消息承载。
进一步，所述指示信息可以包括多个比特位，所述多个比特位与多个UE一一对应，或者，多个比特位中的部分比特位对应同一UE，各比特位用于指示配置给对应UE的后续第一数量的预配置下行资源激活或去激活。
进一步，所述预配置下行资源的配置信息可以包括第一数量的候选值集合，所述指示信息指示的第一数量选自所述候选值集合。
在一个具体实施中，网络可以根据下行资源的紧张程度、所述下行数据所属业务和/或UE上报的辅助信息判断是否激活后续第一数量的预配置下行资源。
进一步，网络可以根据判断结果生成所述指示信息并发送。
由此，网络可以根据业务以及场景自适应的释放或激活预配置下行资源，从而达到节省资源开销的目的。
在一个具体实施中，本实施例所述数据传输方法还可以包括步骤：在指示去激活的后续第一数量的预配置下行资源暂停发送所述下行数据。
也即，对于指示不可用的预配置下行资源，网络不会在该预配置 下行资源向UE发送下行数据。进一步，该不可用的预配置下行资源可以被释放给其他UE使用，或被网络用作他用。
在一个具体实施中，所述预配置下行资源的配置信息可以包括：所述预配置下行资源的周期和起始位置。
在一个具体实施中，所述步骤S701可以包括步骤：在所述UE处于RRC连接态时发送RRC信令，其中，所述RRC信令包括所述预配置下行资源的配置信息。
在一个具体实施中，在所述步骤S702之后，本实施例所述数据传输方法还可以包括步骤：在预配置上行反馈资源接收所述UE对所述下行数据的接收反馈信息。
进一步，所述预配置上行反馈资源与一个或多个所述预配置下行资源相关联。进一步，所述预配置下行资源的配置信息可以包括：与所述预配置下行资源相关联的预配置上行反馈资源相对于所述预配置下行资源的时间间隔。进一步，所述预配置下行资源的配置信息可以包括：所述预配置上行反馈资源的周期和起始位置。
由上，通过预先为UE分配所述预配置下行资源，使得网络能够直接向处于空闲态或非激活态的UE发送下行数据，无需等待UE发起随机接入过程并切换至RRC连接态。由此，下行数据的传输效率得到极大改善，网络侧的信令开销也极大降低。
图8是本发明第四实施例一种数据传输装置的结构示意图。本领域技术人员理解，本实施例所述数据传输装置8可以用于实施上述图7所述实施例中所述的方法技术方案。

采用本实施方案，通过在空闲态或非激活态引入周期性预配置下行资源，并根据业务以及场景自适应的释放或激活预配置下行资源，以更好的实现资源节约，达到节省资源开销的目的。进一步，UE通过预配置下行资源进行数据接收后，能够通过同样预配置的所述预配 置上行反馈资源进行ACK/NACK反馈。
