数据传输的方法和装置
本申请要求于2017年03月24日提交中国专利局、申请号为201710184044.8、发明名称为“数据传输的方法和装置”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
本申请涉及通信领域，并且更具体地，涉及通信领域中数据传输的方法和装置。
背景技术
在无线通信系统中，与网络设备建立了连接的所有用户设备(user equipment，UE)通过共享空口资源，即网络设备在每个传输间隔(transmission time interval，TTI)共享空口资源，即网络设备在每个TTI，根据UE的数据量等信息动态地为其下属的UE分配传输资源，从而提高信道利用率。
在上行数据调度中，UE通过发送缓存状态报告(buffer status report，BSR)，向网络设备报告自己的缓存数据量，从而为网络设备的上行调度提供参考信息，网络设备根据当前可用资源情况和所有UE的BSR及其他信息，为UE分配上行传输资源。
现有的UE上报BSR的方法中，UE通过媒体接入控制(media access control，MAC)控制单元(control element，CE)将BSR上报给网络设备。具体地，MAC层将逻辑信道数据、MAC CE组成的MAC协议数据单元(protocol data unit，PDU)作为一个传输块(transmission，block，TB)，对该传输块进行编码得到编码传输块，然后将该编码传输块发送给网络设备。相应地，网络设备在接收到该编码传输块后，需要对该编码传输块进行解码，才能获知UE发送的MAC协议数据单元中是否携带BSR，并根据该BSR为该UE分配上行资源。因此，通信时延比较长。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1示出了本申请实施例应用的无线通信系统100。该无线通信系统100可以包括至少一个网络设备，图1中示出了网络设备110，网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。该网络设备110可以是GSM系统或CDMA系统中的基站(base transceiver station，BTS)，也可以是WCDMA系统中的基站(nodeB，NB)，还可以是LTE系统中的演进型基站(evolved node B，eNB或eNodeB)，或者是云无线接入网络(cloud radio access network，CRAN)中的无线控制器。该网络设备还可以为中继站、接入点、车载设备、可穿戴设备、未来5G网络中的网络侧设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的多个终端设备，图1中示出了终端设备120和终端设备130。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例不限于此。
应理解，终端设备可以是移动的或固定的。该第一终端设备120和该第二终端设备130可以指接入终端、用户设备(eser equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
本申请实施例中，TTI表示一次数据传输的时间间隔，同时也是最小的调度周期。通信设备在一个TTI内传输的数据块，称为传输块(transmit block，TB)，对一个TTI内的传输块进行调制编码后可以得到编码块(code block，CB)。
在现有技术中，终端设备的第一数据到达之后向网络设备发送资源请求，该资源请求可以为专用的调度请求或者随机接入的前导序列；网络设备在接收到该资源请求后，会为该终端设备分配一块时频资源，并向该终端设备发送上行调度指令。终端设备在接收到该上行调度指令之后，若该终端设备的缓存区中不存在待传输数据，则该终端设备将该第一数据作为传输块，对该传输块进行调制编码得到编码传输块，并通过网络设备分配的时频资源发送该编码传输块，或者，终端设备在接收到该上行调度指令之后，若该终端设备的缓存区中存在待传输数据，则该终端设备将该第一数据和BSR作为传输块，并该传输块进行调制编码得到编码传输块，通过网络设备分配的时频资源发送给该网络设备，该BSR表示该终端设备的缓存区中存在待传输数据的数据量；相应地，该网络设备在接收到该数据包之后，需要在对该数据包进行解码之后，才能获知是否上报BSR，若发送了BSR，则该网络设备根据该BSR为缓存区中待传输数据分配时频资源，并向该终端设备发送该待传输数据的上行调度指令，若不存在，则对该编码传输块进行解码，得到该第一数据。
即现有技术中，网络设备需要对接收到的编码传输块进行解码，才能够得知终端设备是否上报BSR，通信时延比较长。
本申请实施例提供的数据传输的方法和装置，网络设备能够直接得知终端设备是否发送BSR，从而能够降低通信时延。
另外，现有技术中的上报BSR方法只适用于初传该第一数据的场景，若在重传该第一数据时，第二数据到达该终端设备，(该第二数据例如为低时延高可靠性(ultra-reliable low latency communication，URLLC)业务的数据)，即现有的上报BSR的方法不能在重传该第一数据的过程中上报缓存中新到达的第二数据的BSR，因此，需要在完成第一数据的传输之后，才能重新请求调度该第二数据，因此通信时延比较长。
本申请实施例提供的数据传输的方法和装置，终端设备能够在重传数据时向网络设备上报BSR，从而减少通信时延。
应理解，本申请实施例的数据传输的方法中，终端设备可以具有网络功能，网络设备可以具有终端功能，也就是说本申请实施例的数据传输的方法，可以应用于如图1中所示的无线通信系统中任意两个通信设备之间(例如可以为两个终端设备之间、或两个网络设备之间、或终端设备与网络设备之间)的通信，本申请仅以终端设备与网络设备之间的通信为例进行描述，但本申请实施例不限于此。
图2示出了本申请实施例提供的数据传输的方法200的示意性流程图，该方法200可以应用与如图1所示的无线通信系统。

可选地，该第二传输块还包括第二BSR，若该指示信息用于通知该终端设备发送该第一数据时发送该第一BSR，即在重传该第一数据时，终端设备的缓存区中的数据量增加，终端设备需要立即上报缓存区中当前缓存的待传输数据的数据量。
可选地，该指示信息还用于通知用该第一BSR更新该第二BSR。
应理解，终端设备可以根据缓存中待传输数据的服务质量(quality of service，QoS)判定是否需要当即上报缓存区的BSR，例如，对于数据业务的时延要求低于0.5ms，或者时延要求低于n ms级的业务，终端设备会当即上报缓存状态。
本申请实施例提供的数据传输的方法，若该指示信息用于通知发送终端设备在发送该第一数据时未发送第一BSR，该网络设备能够根据该指示信息将该第一编码传输块与该第 二编码传输块进行联合解码，若该指示信息用于通知发送终端设备在发送该第一数据时发送第一BSR，该网络设备将分别对该第一编码传输块与该第二编码传输块进行解码，能够避免网络设备不知道该第一编码传输块中携带第一BSR，将该第一编码传输块与该第二编码传输块进行联合解码，导致解码失败。

可选地，该第二该终端设备可以为携带该第一数据的第一编码传输块和携带该第一BSR的第三编码传输块分配相同的序号，网络设备根据该一编码传输块和该第三编码传输块具有相同的序号，确定该第一编码传输块和该第三编码传输块均为同一轮传输。
可选地，该终端设备可以通过网络设备预分配的时频资源发送该第一编码传输块和该编码指示信息。
可选地，当该第一BSR数据量较小，并且不足以填满上行资源时，剩余的上行资源 可以用来传输第一数据，即终端设备可以将部分第一数据与该第一BSR一起承载在第三传输块上，该第一传输块和该第三传输块共同占用上行调度授权指示或免授权预留的时频资源。
例如，上行调度授权指示当前上行传输分配10个物理资源块(physical resource block，PRB)，采用MCS等级5。终端设备发送2个编码传输块，第一个编码传输块包括第一数据，占用5个PRB，采用MCS等级8。第二个编码传输块包括第一BSR，占用5个PRB，采用MCS等级1。网络设备先检测出第一BSR，判定剩余的上行资源为5PRB，并结合上行调度授权调度时对应的传输块大小判定第一数据采用的MCS等级，进而检测第一数据。
应理解，由于终端设备发送的第一BSR影响网络设备为该终端设备分配时频资源，因此，该终端设备在编码该第一BSR的时候，需要保证该第一BSR的可靠性。
作为一个可选实施例，该第一传输块和该第三传输块可以采用不同的调制编码方案MCS进行编码，即该第三传输块可以采用不同于上行调度授权指示或免授权预定义的第一传输块的MCS进行编码。
可选地，第一传输块和第三传输块的MCS可以为协议约定、网络设备通过高层配置、或终端设备自主选择，其中，对于终端设备自主选择，网络设备需要盲检测BSR采用的MCS。
例如，上行调度授权指示或免授权预定义的MCS为低密度奇偶校验码(low density parity check code，LDPC)，则该第一传输块可以采用预定义的LDPC码进行编码，该第三传输块可以采用极化码(polar)进行编码，本申请实施例对此不作限定。
可选地，该第一传输块的MCS编码等级与该第三传输块的MCS编码等级之间的差值可以是协议约定，网络设备通过高层配置，或终端设备自主选择。对于终端设备自主选择，网络设备需要盲检测第一BSR采用的MCS等级。
例如，上行调度授权指示或免授权预定义的MCS等级为m，其对应的传输可靠性为90％，则该第一传输块可以采用MCS等级m，该第三传输块可以采用MCS等级n，其中n<m，以保证第一BSR具有1％或0.1％或更高的可靠性。
作为另一个可选实施例，该第一传输块和该第三传输块可以采用相同的调制编码方案MCS进行编码，即该第一传输块和该第三传输块都可以采用上行调度授权指示或免授权预定义的第一MCS进行编码。
作为又一个可选实施例，该第一编码传输块和该第三编码传输块可以采用不同发送功率发送，即该第三编码传输块可以采用不同于上行调度授权指示或免授权预定义的发送功率发送。
可选地，该第一编码传输块的发送功率与该第三编码传输块的发送功率之间的差值可以是协议约定，网络设备通过高层配置，或终端设备自主选择。对于终端设备自主选择，如果BSR采用较低的调制方式，例如BPSK或QPSK，则网络设备无需知道该第三传输块的发送功率，直接可以检测到该第一BSR，如果第一BSR采用较高的调制方式，例如16QAM或更高，则网络设备需要盲检测第一BSR。
例如，上行调度授权指示或免授权预定义的发送功率为m，其对应的传输可靠性为90％，则该第一传输块可以采用发送功率q，其中p<q，保证该第一BSR具有1％或0.1％或更高的可靠性。
应理解，本申请实施例中第一编码传输块、编码指示信息和第三编码传输块可以同时发送，或以发送间隔小于预设时间阈值先后发送，本申请实施例对此不作限定。
作为另一个可选实施例，若该指示信息通知该终端设备发送该第一BSR，该第一BSR承载在第一编码传输块上，该网络设备根据该指示信息，对该第一编码传输块进行处理，可以为该网络设备根据该指示信息，对该第一编码传输块进行独立解码，得到该第一数据和该第一BSR。
可选地，该网络设备还可以接收终端设备发送的第三编码传输块，该第三编码传输块包括该第一BSR，该网络设备对该第三编码传输块进行解码，得到该第一BSR。
若该终端设备在发送该第一编码传输块之前发送第二编码传输块，该第一编码传输块和该第二编码传输块都包括该第一数据，且该第二编码传输块还包括第二BSR，则该网络设备在得到该第一BSR之后，将该第二BSR更新为第一BSR，并根据该第一BSR为该终端设备分配时频资源。
本申请实施例提供的数据传输的方法，网络设备可以通过解码编码指示信息，获知终端设备在发送该第一数据时是否发送第一BSR，更进一步地，该在指示信息用于通知发送该第一BSR时，该网络设备可以通过解码第三编码传输块，获得该第一BSR(或更新第二BSR为该第一BSR)，进而根据该第一BSR为终端设备分配时频资源，能够降低通信时延。
可选地，终端设备可以向该网络设备发送指示信息，或者该终端设备可以根据是否发送第一BSR确定第一编码传输块的传输方式，并通过该第一编码传输块的传输方式向该网络设备发送该第一编码传输块，以通过隐性向网络设备发送该指示信息，该指示信息用于通知该终端设备在发送该第一数据时是否发送第一BSR。

可选地，对于免授权传输，网络设备配置了M个预留给免授权的资源池，其中，若终端设备在p个资源池内发送第一编码传输块，则表示该终端设备发送该第一BSR，若终端设备在q个资源池内发送第一编码传输块，则表示该终端设备未发送该第一BSR，其中p+q＝M。
作为一个可选实施例，若终端设备确定不发送该第一BSR，则该终端设备可以在p个资源池中的一个或多个资源池向网络设备发送第一编码传输块，若终端设备确定发送该第一BSR，则该终端设备可以在q个资源池中的一个或多个资源池向网络设备发送第一编码传输块。
相应地，网络设备如果在p个资源池中的一个或多个资源池上接收到终端设备发送的第一编码传输块，则该网络设备可以确定该终端设备在发送该第一编码传输块时发送第一BSR；网络设备如果在q个资源池中的一个或多个资源池上接收到终端设备发送的第一编码传输块，则该网络设备可以确定该终端设备在发送该第一编码传输块时未发送第一BSR。
可选地，终端设备发送该第一编码传输块使用的上行参考信号可以采用ZC序列，其中，ZC序列的根序列由终端设备的标识确定，循环移位项a，与该第一编码传输块是否包含缓存信息对应，其中，a的具体的取值可以是协议约定，或网络设备通过高层信令配置给终端设备。网络设备和终端设备可以预先约定终端设备发送第一BSR和不发送第一BSR时a的取值。
作为一个可选实施例，若终端设备发送第一编码传输块时采用a＝k，则表示该终端设备发送该第一BSR，若终端设备发送第一编码传输块时采用a＝1，则表示该终端设备未发送该第一BSR，其中k不等于l。
相应地，若该网络设备接收该第一编码传输块，并确定该第一编码传输块的上行参考信号采用a＝k，则该网络设备确定该终端设备在发送该第一数据时发送该第一数据，若该网络设备接收该第一编码传输块，并确定该第一编码传输块的上行参考信号采用a＝1，则该网络设备确定该终端设备在发送该第一数据时未发送该第一数据。
可选地，由于上行参考信号由2部分组成，即一个完整的序列分成相同长度的两段，因此，若该终端设备使用第一段序列和第二段序列完全相同的导频序列，则表示该终端设备发送该第一BSR，若该终端设备使用第一段序列和第二段序列不同的导频序列，则表示该终端设备未发送该第一BSR。
相应地，网络设备通过检测到的导频序列判定第一编码传输块是否包含第一BSR。
可选地，第一段序列和第二段序列的相移值可以是协议约定，或网络设备通过高层信令配置给终端设备。
