数据传输方法、装置、设备及存储介质 技术领域

背景技术
在第五代移动通信技术(The 5th Generation Mobile Communication，5G)系统中，用户设备(User Equipment，UE)通常基于调度的发送方式向演进型基站(Evolved Node B，eNB)发送上行数据。
相关技术中，在UE处于休眠态或者不活跃态下，当UE存在待发送的上行数据时，UE需要发起随机接入过程进入连接态。在UE进入连接态之后，E向eNB发送上行调度请求(Scheduling Request，SR)；eNB根据该SR向UE配置一个上行调度授权(Up Link Grant，UL Grant)，该UL Grant用于向UE配置上行传输资源。UE在正确解码得到UL Grant时，根据eNB配置的上行传输资源向eNB发送上行数据。

具体实施方式
以下将参考附图详细说明本公开的各种示例性实施例、特征和方面。附图中相同的附图标记表示功能相同或相似的元件。尽管在附图中示出了实施例的各种方面，但是除非特别指出，不必按比例绘制附图。
在这里专用的词“示例性”意为“用作例子、实施例或说明性”。这里作为“示例性”所说明的任何实施例不必解释为优于或好于其它实施例。
另外，为了更好的说明本公开，在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解，没有某些具体细节，本公开同样可以实施。在一些实例中，对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述，以便于凸显本公开的主旨。
相关技术中，在UE处于休眠态或者不活跃态下，当UE存在待发送的上行数据时，UE需要发起随机接入过程进入连接态。在UE进入连接态之后，E向eNB发送上行调度请求(Scheduling Request，SR)；eNB根据该SR向UE配置一个上行调度授权(Up Link Grant，UL Grant)，该UL Grant用于向UE配置上行传输资源。UE在正确解码得到UL Grant时，根据eNB配置的上行传输资源向eNB发送上行数据。
但是在上述的数据传输机制中，UE和eNB之间的交互流程较为繁琐，整个过程耗时较长，导致上行数据的传输效率较低。
本公开实施例通过在终端设备处于休眠态或者不活跃态下引入预配置的周期性的上行传输资源单元即上行预配置资源单元，使得终端设备可以在上行预配置资源单元上直接发送上行指示信号，上行指示信号包括上行序列或者上行数据；避免了相关技术中终端设备需要发起随机接入进入连接态的情况，减少了终端设备与接入网设备之间的交互流程，降低了信令开销和终端设备的设备能耗，提高了上行数据的传输效率。

请参考图2，其示出了本公开一个示例性实施例提供的数据传输方法的流程图，本实施例以该方法用于图1所示的移动通信系统中来举例说明。该方法包括以下几个步骤。
步骤201，终端设备处于休眠态或者不活跃态下，在上行预配置资源单元上发送上行指示信号。
其中，终端设备的状态包括休眠态、不活跃态和连接态中的一种。
可选的，连接态是终端设备和接入网设备之间存在无线资源控制(Radio Resource Control，RRC)连接的状态。休眠态也称为空闲态(英文：idle)，是终端设备和接入网设备之间没有RRC连接的状态，并且终端设备和接入网设备中保存或未保存终端设备的上下文信息。不活跃态也称为非激活态(英文：inactive)，是不同于空闲态和连接态的一种状态，由移动通信网触发处于连接态的终端设备进入非激活态，此时终端设备和移动通信网均保存在非激活态之前的连接态时的终端设备的上下文信息。
可选的，在终端设备处于休眠态或者不活跃态的情况下，当终端设备存在上行数据需要发送时，在上行预配置资源单元上发送上行指示信号。

综上所述，本公开实施例通过在终端设备处于休眠态或者不活跃态下引入预配置的周期性的上行传输资源单元即上行预配置资源单元，使得终端设备可以在上行预配置资源单元上直接发送上行指示信号，对应的，接入网设备在上行预配置资源单元上接收终端设备发送的上行指示信号；避免了相关技术中终端设备需要发起随机接入进入连接态的情况，减少了终端设备与接入网设备之间的交互流程，降低了信令开销和终端设备的设备能耗，提高了上行数据的传输效率。
请参考图3，其示出了本公开另一个示例性实施例提供的数据传输方法的流程图，本实施例以该方法用于图1所示的终端设备中来举例说明。该方法包括以下几个步骤。
步骤301，终端设备在上行指示信号发送时机对应的上行预配置资源单元上发送上行指示信号。
可选的，终端设备在上行指示信号发送时机对应的上行预配置资源单元上发送上行指示信号之前，还包括：接入网设备向终端设备预配置上行指示信号发送时机，对应的，终端设备接收接入网设备预配置的上行指示信号发送时机。其中，上行指示信号发送时机是周期性的用于指示发送上行指示信号的发送时机。
可选的，上行指示信号发送时机包括多个上行预配置资源单元。
在一种可能的实现方式中，多个上行预配置资源单元中的每个上行预配置资源单元只能发送上行序列。在另一种可能的实现方式中，多个上行预配置资源单元中的每个上行预配置资源单元既能发送上行序列，又能发送上行数据。
终端设备在上行指示信号发送时机对应的上行预配置资源单元上发送上行指示信号，包括但不限于以下几种可能的实现方式：
在一种可能的实现方式中，当在上行指示信号发送时机上存在上行数据需要发送时，终端设备在上行指示信号发送时机对应的特定的上行预配置资源单元上发送上行数据。
可选的，上行指示信号发送时机包括多个上行预配置资源单元，上行指示信号发送时机对应的特定的上行预配置资源单元为多个上行预配置资源单元中的至少一个。
上行指示信号发送时机对应的特定的上行预配置资源单元可以是预配置的，或者是预定义的。本实施例对此不加以限定。
在另一种可能的实现方式中，当在上行指示信号发送时机上存在上行数据需要发送时，终端设备在上行指示信号发送时机发送上行序列；接收下行指示信息，在当前周期内的普通预配置资源上发送上行数据。
可选的，当在上行指示信号发送时机上存在上行数据需要发送时，终端设备在上行指示信号发送时机对应的特定的上行预配置资源单元上发送上行序列。

上行指示信号发送时机关联多个普通预配置资源。可选的，上行指示信号发送时机为上行预配置资源窗内的开始位置，上行预配置资源窗包括多个普通预配置资源。
步骤302，接入网设备在上行指示信号发送时机对应的上行预配置资源单元上，接收终端数设备发送的上行指示信号。

对应的，终端设备在未接收到下行指示信息的情况下，当存在上行数据需要发送时发送随机接入请求，将终端设备的设备状态切换为连接态；在连接态下发送上行数据。
可选的，终端设备未接收到下行指示信息，用于指示当前周期内的普通预配置资源不能用于传输该终端设备的上行数据，终端设备在当前周期内上行数据发送需要回退至相关技术中的传输机制，即回退至随机接入过程。
在终端设备向接入网设备发送随机接入请求之后，接入网设备接收该随机接入请求。接入网设备在接收到终端设备发送的随机接入请求后，接收处于连接态的终端设备发送的上行数据。
综上所述，本公开实施例还通过终端设备发送上行指示信号后没有接收到接入网设备的响应，则回退至随机接入过程，即当存在上行数据需要发送时发送随机接入请求，将终端设备的设备状态切换为连接态，在连接态下发送上行数据；使得当前周期内的普通预配置资源可以空出来给接入网设备作其他调度，有效地解决了上行预配置资源单元所带来的资源开销问题。
需要说明的是，由于可能存在的上下行波束对齐问题，本公开实施例还通过将每个上行预配置资源单元关联一个或者多个下行发送波束，使得接入网设备可以根据上行指示信号对应的上行预配置资源单元位置来确定下行发送波束。请参考图4，其示出了本公开另一个示例性实施例提供的数据传输方法的流程图，本实施例以该方法用于图4所示的终端设备中来举例说明。该方法包括以下几个步骤。
步骤401，当在上行指示信号发送时机上存在上行数据需要发送时，终端设备在上行指示信号发送时机发送上行序列。
需要说明的是，当在上行指示信号发送时机上存在上行数据需要发送时，终端设备在上行指示信号发送时机发送上行序列可参考上述实施例中的相关细节，在此不再赘述。
步骤402，接入网设备在接收到终端设备在上行指示信号发送时机发送上行序列后，在下行发送波束上发送下行指示信息。

接入网设备中存储有上行预配置资源单元与下行发送波束的关联关系。
可选的，终端设备在接收到终端设备在上行指示信号发送时机发送上行序列后，根据存储的关联关系确定与该上行指示信号发送时机对应的一个或者多个下行发送波束。接入网设备在一个或者多个下行发送波束上发送下行指示信息。
接入网设备在接收到该上行序列后，接入网设备在下行发送波束上发送下行指示信息，执行步骤403；或者，接入网设备在接收到该上行序列后，不进行响应，终端设备未接收到接入网设备的响应，回退至随机接入过程。
步骤403，终端设备接收下行发送波束上发送的下行指示信息。
接入网设备在下行发送波束上发送下行指示信息后，终端设备接收接入网设备在下行发送波束上发送的下行指示信息。
可选的，终端设备接收到在一个或者多个下行发送波束上发送的下行指示信息。
步骤404，终端设备在当前周期内的普通预配置资源上发送上行数据。
可选的，终端设备在当前周期内选择至少一个普通预配置资源，在选择的至少一个普通预配置资源上发送上行数据。
可选的，当前周期为终端设备发送上行序列的上行指示信号发送时机的周期。上行指示信号发送时机的周期是普通预配置资源的周期的N+1倍，即终端设备在上行预配置资源单元上发送上行指示信号，可以激活N个普通预配置资源，其中N为正整数。
步骤405，接入网设备在当前周期内的普通预配置资源上接收终端设备发送的上行数据。
终端设备在当前周期内的普通预配置资源上发送上行数据后，对应的，接入网设备在该普通预配置资源上接收终端设备发送的上行数据。
在一个示意性的例子中，如图5所示，引入预配置的周期性(比如，周期为T)的上行指示信号发送时机，即终端设备在特定的上行指示信号发送时机51发送上行序列。此外，由于存在上下行波束对 齐问题，上行指示信号发送时机51存在多个上行预配置资源单元52，每个上行预配置资源单元52只能发送上行序列，且每个上行预配置资源单元52关联了一个或者多个接入网设备的下行发送波束，接入网设备可以根据上行指示信号对应的上行预配置资源单元52的位置来确定下行发送波束。
接入网设备接收到终端设备发送的上行指示信号后，会下发的响应给终端设备，终端设备在下行接收窗53接收到接入网设备下发的响应后，才能利用当前周期T内的普通预配置资源54发送上行数据。如果终端设备发送指示信号后，没有收到接入网设备下发的响应，当前周期T内的上行预配置资源不能用于传输该终端设备的上行数据，终端设备在当前周期内上行数据发送需要回退到相关技术中的数据传输机制，即回退到随机接入过程。
在一个示意性的例子中，如图6所示，引入预配置的周期性(比如，周期为T)的上行指示信号发送时机61，即终端设备在特定的上行指示信号发送时机61发送上行序列或上行数据。此外，由于存在上下行波束对齐问题，每个上行指示信号发送时机61存在多个上行预配置资源单元62，每个上行预配置资源单元62既能发送上行序列，又能发送上行数据。当终端设备在上行指示信号发送时机61存在上行数据需要发送时，终端设备可以在该上行指示信号发送时机61中选择特定的上行预配置资源单元62发送上行数据。每个上行预配置资源单元62关联了一个或者多个接入网设备的下行发送波束，接入网设备可以根据上行指示信号对应的上行预配置资源单元62的位置来确定下行发送波束。
接入网设备接收到终端设备发送的上行指示信号后，会下发的响应给终端设备，终端设备在下行接收窗63接收到接入网设备下发的响应后，才能利用当前周期T内的普通预配置资源64发送上行数据。如果终端设备发送指示信号后，没有收到接入网设备下发的响应，当前周期T内的上行预配置资源不能用于传输该终端设备的上行数据，终端设备在当前周期内上行数据发送需要回退到相关技术中的数据传输机制，即回退到随机接入过程。
在一个示意性的例子中，如图7所示，上行预配置资源窗73内存在多个普通预配置资源75，且上行预配置资源窗73的周期为T，每个上行预配置资源窗73的开始位置为上行指示信号发送时机71，即终端设备在特定的上行指示信号发送时机71发送上行序列。此外，由于存在上下行波束对齐问题，每个上行指示信号发送时机71存在多个上行预配置资源单元72，每个上行预配置资源单元72只能发送上行序列。每个上行预配置资源单元72关联了一个或者多个接入网设备的下行发送波束，接入网设备可以根据上行指示信号对应的上行预配置资源单元72的位置来确定下行发送波束。
接入网设备接收到终端设备发送的上行指示信号后，会下发的响应给终端设备，终端设备在下行接收窗74接收到接入网设备下发的响应后，才能利用当前周期T内的普通预配置资源75发送上行数据。如果终端设备发送指示信号后，没有收到接入网设备下发的响应，当前周期T内的上行预配置资源不能用于传输该终端设备的上行数据，终端设备在当前周期内上行数据发送需要回退到相关技术中的数据传输机制，即回退到随机接入过程。
在一个示意性的例子中，如图8所示，上行预配置资源窗83内存在多个普通预配置资源85，且上行预配置资源窗83的周期为T，每个上行预配置资源窗83的开始位置为上行指示信号发送时机81，即终端设备在特定的上行指示信号发送时机81发送上行序列或者上行数据。此外，由于存在上下行波束对齐问题，每个上行指示信号发送时机81存在多个上行预配置资源单元82，每个上行预配置资源单元82既能发送上行序列，又能发送上行数据。当终端设备在上行指示信号发送时机81存在上行数据需要发送时，终端设备可以该上行指示信号发送时机81选择特定的上行预配置资源单元82发送上行数据。每个上行预配置传输资源单元关联了一个或者多个接入网设备的下行发送波束，接入网设备可以根据上行指示信号对应的上行预配置资源单元82的位置来确定下行发送波束。
接入网设备接收到终端设备发送的上行指示信号后，会下发的响应给终端设备，终端设备在下行接收窗84接收到接入网设备下发的响应后，才能利用当前周期T内的普通预配置资源85发送上行数据。如果终端设备发送指示信号后，没有收到接入网设备下发的响应，当前周期T内的上行预配置资源不能用于传输该终端设备的上行数据，终端设备在当前周期内上行数据发送需要回退到相关技术中的数据传输机制，即回退到随机接入过程。
综上所述，由于可能存在的上下行波束对齐问题，本公开实施例还通过将每个上行预配置资源单元关联一个或者多个下行发送波束，使得接入网设备可以根据上行指示信号对应的上行预配置资源单元位置来确定下行发送波束，进而使得终端设备接收到在该下行发送波束上发送的下行指示信息，保证了上下行波束的对齐。
