Description

一种数据传输方法、网络设备、通信设备及存储介质
本申请要求在2018年07月18日提交中国专利局、申请号为201810792771.7、发明名称为“一种数据传输方法、网络设备、通信设备及存储介质”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
本申请涉及通信领域，尤其涉及一种数据传输方法、网络设备、通信设备及存储介质。
背景技术
随着通信技术的发展，在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)中提出了基于蜂窝网络的车联网技术。车联网技术提供了车到车(Vehicle to Vehicle，V2V)、车到人(Vehicle to Pedestrian，V2P)、车到基础设施(Vehicle to Infrastructure，V2I)和车到网络(Vehicle to Network，V2N)的智能交通业务。其中，V2N使用的是上下行链路进行通信。V2V、V2P和V2I使用的是侧行链路进行通信，侧行链路通信是基于通信设备和通信设备之间直接通信定义的，不需要基站转发。
现有技术中，当通信设备有需要发送的数据时，通信设备会向网络设备发送调度请求，网络设备接收通信设备发送的调度请求，并根据接收到的调度请求生成调度授予信息，之后，网络设备向通信设备发送调度授予信息。通信设备根据调度授予信息发送需要发送的数据；其中，调度授予信息包括分配给通信设备的时频资源。
当网络设备给多个通信设备分配的时域资源相同时，会出现有多个通信设备在相同的时域资源上向一个通信设备发送数据，进而可能会造成数据之间的相互干扰。特别是，距离接收端近的通信设备对距离接收端远的通信设备发送的数据的干扰较强。以图1为例说明，图1中以通信设备101、通信设备102、通信设备103和网络设备110为例；其中，通信设备102距离通信设备101较近，通信设备103距离通信设备101较远。当网络设备110为通信设备102和通信设备103分配的时域资源相同、通信设备102和通信设备103在相同的时域资源上发送数据时，通信设备102发送的数据可能会对通信设备103发送的数据造成较强的干扰，进而会降低通信设备101对通信设备103发送的数据的译码率。
发明内容
本申请实施例提供一种数据传输方法、网络设备、通信设备及存储介质，用于在多个通信设备向一个通信设备发送数据时，减小多个通信设备发送的数据之间的相互干扰。
第一方面，本申请实施例提供一种数据传输方法，包括网络设备确定目标通信设备组的时间窗，其中，所述目标通信设备组包括至少两个通信设备，所述目标通信设备组中的两个通信设备之间的距离小于或等于阈值，所述时间窗用于使所述目标通信设备组的至少两个通信设备通过侧行链路在所述时间窗发送和接收数据；所述网络设备向所述目标通信设备组的至少两个通信设备发送第一指示信息，所述第一指示信息用于指示所述时间窗。
本申请实施例中，目标通信设备组中的两个通信设备之间的距离小于或等于距离阈值， 因此，对于接收端的通信设备来说，目标通信设备组中的至少两个通信设备距离接收端的通信设备的距离比较接近。如此，可以避免背景技术中提到的在相同时间窗发送数据的通信设备因距离作为接收端的通信设备的距离相差较大，造成目标通信设备组中至少两个通信设备发送的数据之间相互干扰的问题，可以提高作为接收端的通信设备对目标通信设备组中至少两个通信设备发送的数据的译码率。
一种可能地实现方式中，所述时间窗包括N个时间单元，所述N个时间单元包括K个第一时间单元和L个第二时间单元，其中，所述N为大于或等于2的整数，所述K为大于或等于1的整数，所述L为大于或等于1且小于等于(N-K)的整数，所述第一指示信息包括至少两个样式，所述至少两个样式中的每个样式分别由所述K个第一时间单元和所述L个第二时间单元组合形成、且所述至少两个样式中的每个样式的K个第一时间单元和L个第二时间单元组合形式不一样；所述网络设备向第一通信设备发送第一样式，向第二通信设备发送第二样式，所述第一样式用于指示所述第一通信设备在所述第一样式中包括的K个第一时间单元上发送第一数据，所述第二样式用于指示所述第二通信设备在所述第二样式中包括的L个第二时间单元中的至少一个第二时间单元上接收所述第一数据，所述第一样式和所述第二样式均属于所述至少两个样式，所述第一通信设备和所述第二通信设备均属于所述目标通信设备组。
本申请实施例中，网络设备通过向第一通信设备发送第一样式，向第二通信设备发送第二样式，第一通信设备在第一样式中包括的K个第一时间单元上发送第一数据，第二通信设备在所述第二样式中包括的L个第二时间单元中的至少一个第二时间单元上接收所述第一数据，进而可使得第一通信设备和第二通信设备在一个时间窗内实现全双工的效果。进一步，第一通信设备和第二通信设备均属于目标通信设备组，因此，通过本申请实施例可以实现在一个时间窗，目标通信设备组中的任一通信设备发送的数据均可被组内的其它通信设备接收到，即在一个时间窗，任一通信设备均能接收到通信设备组中其它通信设备发送的数据。
一种可能的实施方式中，所述网络设备可以根据所述至少两个通信设备的参数信息确定所述目标通信设备组，其中，所述参数信息可以但不限于包括所述至少两个通信设备的位置信息。
一种可能的实施方式中，所述网络设备可以根据所述目标通信设备组中包括的通信设备的数量确定所述目标通信设备组的时间窗。
一种可能的实施方式中，为了使得确定出的通信设备的样式可以满足通信设备的业务需求，所述第一样式中的K个第一时间单元的位置可以是根据所述第一通信设备的业务延时需求确定的；所述第二样式中的K个第一时间单元的位置可以是根据所述第二通信设备的业务延时需求确定的；其中，针对所述目标通信设备组中的至少两个通信设备，业务延时小的通信设备对应的样式中包括的第一时间单元位于业务延时大的通信设备对应的样式中包括的第一时间单元之前。如此，可以使得业务延时小的通信设备可以较快的将待发送的数据发送出去，以满足通信设备对不同的业务的处理需求。
第二方面，本申请实施例提供一种数据传输方法，包括第一通信设备接收网络设备发送的第一指示信息，所述第一指示信息用于指示时间窗，所述时间窗为所述网络设备为目标通信设备组确定的，所述目标通信设备组包括至少两个通信设备，所述目标通信设备组中的两个通信设备之间的距离小于或等于阈值，所述第一通信设备为所述目标通信设备组 中任一个；所述第一通信设备在所述时间窗发送和接收数据。
本申请实施例中，对于同一个接收端的通信设备，目标通信设备组中的至少两个通信设备距离作为接收端的通信设备的距离比较接近，因此，目标通信设备组中的其它通信设备发送的数据对第一通信设备发送的数据干扰较小，进而可以提高接收端的通信设备对第一通信设备发送的数据的译码率。而且，当第一通信设备在所述时间窗接收数据时，由于目标通信设备组中的两个通信设备之间的距离小于或等于距离阈值，因此，目标通信设备组中的其他通信设备距离作为接收端的第一通信设备的距离都比较接近，如此，有助于避免在相同时间窗发送数据的通信设备距离相差较大，造成通信设备发送的数据之间相互干扰的问题，进而，可提高第一通信设备的译码率。
一种可能地实现方式中，所述时间窗包括N个时间单元，所述N个时间单元包括K个第一时间单元和L个第二时间单元，其中，所述N为大于或等于2的整数，所述K为大于或等于1的整数，所述L为大于或等于1且小于等于(N-K)的整数，所述第一指示信息包括至少两个样式，所述至少两个样式中的每个样式分别由所述K个第一时间单元和所述L个第二时间单元组合形成、且所述至少两个样式中的每个样式的K个第一时间单元和L个第二时间单元组合形式不一样；所述第一通信设备接收所述网络设备发送的第一样式之后，所述第一通信设备在所述第一样式中包括的K个第一时间单元上发送第一数据、在所述第一样式中包括的L个第二时间单元中的至少一个第二时间单元上接收第二数据，所述第二数据为第二通信设备在第二样式中包括的K个第一时间单元上发送的，所述第一样式和所述第二样式均属于所述至少两个样式，所述第二通信设备为所述目标通信设备组中除所述第一通信设备外的一个。
本申请实施例中，第一通信设备在第一通信设备的第一样式中包括的K个第一时间单元上发送第一数据，第二通信设备在第二通信设备的第二样式中包括的L个第二时间单元中的至少一个第二时间单元上接收到第一数据，第二通信设备在第二样式中包括的K个第一时间单元上发送第二数据，第一通信设备在所述第一样式中包括的L个第二时间单元中的至少一个第二时间单元上接收第二数据，如此，可以实现在一个时间窗内第一通信设备发送的第一数据被第二通信设备接收到，相应地，在一个时间窗内第二通信设备发送的第二数据也被第一通信设备接收到，进而，在一个时间窗内第一通信设备和第二通信设备可实现全双工的效果。
一种可能的实施方式中，为了便于接收端的通信设备(比如第二通信设备)确定在一个时间窗内是要继续等待接收第一数据还是结束在该时间窗内的数据接收，所述第一通信设备可以在所述第一样式中包括的K个第一时间单元上发送第二指示信息，所述第二指示信息用于指示所述第一样式中包括的发送所述第一数据的当前第一时间单元在所述第一样式中包括的K个第一时间单元中的位置。可选地，当第一样式中包括的发送第一数据的当前第一时间单元在所述第一样式中包括的K个第一时间单元中的位置为最后一个位置，则作为接收端的通信设备可以结束该时间窗内数据的传输；当不是最后一个位置，则作为接收端的通信设备可以继续等待接收第一通信设备后续发送的第一数据。
一种可能的实施方式中，所述第一通信设备接收第三指示信息，所述第三指示信息用于指示所述第二样式中包括的发送所述第二数据的当前第一时间单元在所述第二样式中包括的K个第一时间单元中的位置；当所述第一通信设备对所述第二数据译码失败、且确定所述第三指示信息指示的所述第二样式中包括的当前第一时间单元的位置不是所述第 二样式中包括的K个第一时间单元中的最后一个时，所述第一通信设备接收所述第二通信设备在所述第二样式的后一个第一时间单元上发送的所述第二数据；所述后一个第一时间单元为所述第二样式中包括的K个第一时间单元中位于所述第三指示信息指示的所述第二样式中包括的当前第一时间单元之后的一个第一时间单元；所述第一通信设备对两次接收到的所述第二数据合并译码。在一种可能的实施方式中，当所述第一通信设备合并译码失败时，返回所述第一通信设备接收所述第二通信设备在所述第二样式中包括的后一个第一时间单元上发送的所述第二数据的步骤，直至译码成功或者确定用于发送所述第二数据的所述第二样式中包括的当前第一时间单元的位置是所述第二样式中包括的K个第一时间单元中的最后一个为止。
通过第三指示信息中指示的所述第二样式中包括的发送所述第二数据的当前第一时间单元在所述第二样式中包括的K个第一时间单元中的位置，第一通信设备可以较为快速的确定出要等待接收第二设备后续发送的第二数据还是结束在该时间窗内的数据传输，进而可以节省第一通信设备的资源。

具体实施方式
图2示例性示出了本申请实施例提供的一种通信系统架构示意图，通信系统中可包括网络设备和通信设备。图2以通信系统包括一个网络设备和五个通信设备为例说明，如图2所示，该通信系统包括网络设备210、通信设备201、通信设备202、通信设备203、通信设备204和通信设备205。网络设备210通过无线的方式分别与通信设备201、通信设备202、通信设备203、通信设备204和通信设备205进行通信，主要是利用Uu空口传输。通信设备201、通信设备202、通信设备203、通信设备204和通信设备205之间可通过无线的方式进行通信，主要是利用侧行链路(Sidelink，SL)空口传输。例如可以是V2X通信系统中V2V、V2P和V2I之间通过侧行链路直接通信，也可以是其它设备到设备(device-to-device，D2D)之间的通信，其中，侧行链路是针对通信设备和通信设备之间直接通信定义的，也就是说通信设备和通信设备之间的通信不需要通过基站的转发。本申请实施例的通信系统可以是通用移动通信系统(universal mobile telecommunications system，UMTS)，或者是长期演进(long term evolution，LTE)无线通信系统，或者是第五代(5th generation，5G)移动通信系统等。
网络设备在UMTS中可以是宏演进型基站(evolved node B，eNB)，在LTE无线通信系统中可以是宏基站eNB，在5G移动通信系统中可以基站gNB，gNB可以作为宏站，也可以作为微站。网络设备的组网方式可以为宏微异构网络HetNet，或者是新型无线接入网(Radio Access Network，C-RAN)，或者是分布式场景等。其中，C-RAN是基于集中化处理(centralized processing)，协作式无线电(collaborative radio)和实时云计算构架(real-time cloud infrastructure)的绿色无线接入网构架(clean system)。在不同的网络组网方式中，如在HetNet组网中可以是微基站、微微基站或者家庭基站等，在C-RAN组网中可以是基带处理单元池(building base band unit pool，BBU pool)和射频单元RRU，在分布式基站场景中可以是基带处理单元(building base band unit，BBU)和射频单元(Radio Remote Unit，RRU)。
通信设备可以是手机、平板电脑、具有通信功能的车辆和具有通信功能的路边基础设 施等。在图2中，通信设备201和通信设备202之间的距离、通信设备201和通信设备203之间的距离、通信设备202和通信设备203之间的距离，以及通信设备204和通信设备205之间的距离均小于或等于阈值。通信设备201分别与通信设备204和通信设备205之间的距离均大于阈值，通信设备202分别与通信设备204和通信设备205之间的距离均大于阈值，通信设备203分别与通信设备204和通信设备205之间的距离也均大于阈值。一种可能的实施方式中，通信设备201、通信设备202和通信设备203可以在一个区域，通信设备204和通信设备205可以在另一个区域，且两个区域之间的距离大于阈值。
应理解，本申请实施例中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。“和/或”，用于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：只存在A，只存在B以及同时存在A和B三种情况，其中A，B可以是单数或者复数。
基于上述内容，图3示例性示出了本申请实施例提供的一种数据传输方法流程示意图。该实施例中网络设备可以是上述图2中的网络设备210，目标通信设备组可以是上述图2中的第一通信设备组和第二通信设备组中的任意一个，当目标通信设备组为上述图2中的第一通信设备组时，目标通信设备组中的至少两个通信设备可以是上述图2中通信设备201、通信设备202和通信设备203中的至少两个；当目标通信设备组为上述图2中的第二通信设备组时，目标通信设备组中的至少两个通信设备可以是上述图2中的通信设备204和通信设备205。如图3所示，该方法包括：
步骤S301，网络设备确定目标通信设备组的时间窗。
由上述介绍可知，目标通信设备组包括至少两个通信设备，目标通信设备组中的至少两个通信设备中的任何两个通信设备之间的距离均小于或等于阈值，其中，阈值可以预先根据经验值确定。时间窗用于使目标通信设备组中的至少两个通信设备通过侧行链路在时间窗内发送和接收数据。
可选地，时间窗可表示一段时间长度，用于标识网络设备分配给通信设备的接收和发送数据的时间长度。可选地，时间窗也可称为时间长度或者时域资源。一种可能的实施方式中，时间窗包括N个时间单元；其中，N为大于或等于2的整数，时间单元包括但不限于帧、子帧、时隙、微时隙、或正交频分复用(Orthogonal frequency division multiplex，OFDM)符号等；其中，帧、子帧、时隙、微时隙和符号之间存在关联关系，例如5G新空口(new radio，NR)定义的时隙中，如果采用扩展循环前缀(extended cyclic prefix，ECP)时，2个符号组成一个微时隙，相邻两个微时隙之间可包括一个间隔GAP，一个GAP的大小可以是一个OFDM符号的长度，用于对相邻两个微时隙之间的收发功能进行转换，因此，一个时隙包括4个微时隙，即一个时隙包括12个符号。图4示例性示出了本申请实施例提供的一种时间窗的结构示意图，该时间窗的时间单元以微时隙为例说明。如图4所示，该时间窗包括8个微时隙；其中，4个微时隙组成一个时隙，相邻2个微时隙之间隔一个用于接收数据和发送数据转换的GAP；当图4中GAP为一个符号时，一个时隙包括12个符号，一个时间窗包括24个符号。一种可能的实现方式中，如果网络设备的性能较高时，如收发转换时延较小，或者使用两个或两个以上无线传输通道时，则GAP的时长可以小于一个符号，或者可以直接省去。
步骤S302，网络设备向目标通信设备组的至少两个通信设备发送第一指示信息；其中，第一指示信息用于指示所述时间窗。相应地，第一通信设备接收网络设备发送的第一指示 信息。
网络设备向目标通信设备组中的至少两个通信设备发送第一指示信息的方式可有如下两种方式实现。
第一种实现方式，网络设备在向目标通信设备组中的至少两个通信设备发送调度授予信息时，在下行控制信息(downlink control information，DCI)中携带第一指示信息，其中，调度授予信息包括分配给目标通信设备组中至少两个通信设备的频域资源、调制编码方式等。可选地，网络设备可通过新空口-物理下行控制信道(new radio-physical downlink control channel，NR-PDCCH)向通信设备发送DCI。
第二种实现方式，网络设备在确定出目标通信设备组的时间窗后，可在无线资源控制信息(radio resource contro,RRC)中携带第一指示信息，直接向目标通信设备组的至少两个通信设备发送第一指示信息，其中，RRC包括给目标通信设备组中至少两个通信设备配置的控制信道信息、传输信道信息、协议栈信息等。
示例性的，第一指示信息可以是在DCI消息或者RRC消息中新增一个字段，用该字段来标识第一指示信息。
其中，第一通信设备为目标通信设备组中的一个通信设备。结合图2来说明，当目标通信设备组为第一通信设备组时，第一通信设备可以为通信设备201、通信设备202和通信设备203中的一个；当目标通信设备组为第二通信设备组时，第一通信设备组为通信设备204和通信设备205中的一个。
步骤S303，第一通信设备在时间窗发送和接收数据。
本申请实施例中，通过上述步骤S301至步骤S304可以看出，网络设备向目标通信设备组的至少两个通信设备发送第一指示信息，目标通信设备组的至少两个通信设备通过侧行链路在第一指示信息指示的时间窗发送和接收数据，由于目标通信设备组中的两个通信设备之间的距离小于或等于距离阈值，因此，对于接收端的通信设备来说，目标通信设备组中的至少两个通信设备距离接收端的通信设备的距离比较接近。如此，可以避免背景技术中提到的在相同时间窗发送数据的通信设备因距离接收端的通信设备的距离相差较大，造成目标通信设备组中至少两个通信设备发送的数据之间相互干扰的问题，可以提高接收端的通信设备对目标通信设备组中至少两个通信设备发送的数据的译码率。
进一步，由于目标通信设备组中的两个通信设备之间的距离小于或等于阈值，对于目标通信设备组中的第一通信设备，目标通信设备组中其它通信设备到第一通信设备的距离比较接近，因此，也可以提高第一通信设备对其它通信设备发送的数据的译码率。
在上述步骤S301之前，对于接收端的通信设备，在一个时间窗内可能会接收到多个通信设备发送的数据，为了尽可能避免多个通信设备发送的数据之间相互干扰，提高接收端的通信设备的译码率，网络设备可预先对各通信设备进行分组。本申请实施提供了两种网络设备确定通信设备组的实施方式。
实施方式一，网络设备获取至少两个通信设备的参数信息，比如位置信息，根据至少两个通信设备的位置信息进行分组。结合图2来说明，网络设备210获取通信设备201、通信设备202、通信设备203、通信设备204和通信设备205的位置信息，根据获取到各通信设备的位置信息，将各通信设备中距离小于或等于阈值的通信设备划分为一个组，即网络设备210可将通信设备201、通信设备202和通信设备203确定为第一通信设备组(如图2所示)，将通信设备204和通信设备205确定为第二通信设备组(如图2所示)。可选 地，通信设备位置可能会随着时间发生变化，为了提高分组的精确度，网络设备可根据至少两个通信设备的当前位置信息进行分组。
实施方式二，为了使得确定出的通信设备组中的各通信设备的业务延时需求比较接近，以便于网络设备一起调度时，可以满足各通信设备的业务需求，网络设备可以获取至少两个通信设备当前的业务延时需求，网络设备根据至少两个通信设备的位置信息和业务延时需求划分组。结合图2说明，当网络设备确定出通信设备201和通信设备202之间的距离、通信设备201和通信设备203之间的距离、以及通信设备202和通信设备203之间的距离均小于或等于阈值，且确定出通信设备201、通信设备202和通信设备203的业务延时需求均在第一预设范围时，将通信设备201、通信设备202和通信设备203确定为第一通信设备组(如图2所示)。当网络设备确定出通信设备204和通信设备205之间的距离小于或等于阈值，且通信设备204和通信设备205的业务延时需求均在第二预设范围时，将通信设备204和通信设备205确定为第二通信设备组(如图2所示)。
一种可能的实施方式中，当网络设备确定出通信设备201和通信设备202之间的距离、通信设备201和通信设备203之间的距离、以及通信设备202和通信设备203之间的距离均小于或等于阈值，且通信设备201和通信设备202的业务延时需求均在第一预设范围，通信设备203的业务延时需求在第三预设范围时，将通信设备201和通信设备202确定为第一通信设备组，将通信设备203确定为第三通信设备组。也就是说，一个通信设备也可以属于两个或两个以上的不同通信设备组。
在上述实施方式一中，网络设备获取至少两个通信设备位置信息有不同的获取方法。在一种可能的应用场景中，各通信设备可周期性地向网络设备上报位置信息，网络设备周期性的接收各通信设备上报的位置信息，在该应用场景下，网络设备在接收到各通信设备上报的位置信息后，可以对各通信设备预先进行分组。在另一种可能的应用场景中，网络设备可以触发通信设备将位置信息携带在测量上报消息中发送至网络设备，网络设备根据接收到的测量上报消息中携带的位置信息对各通信设备分组。
在上述实施方式二中，网络设备获取至少两个通信设备位置信息和业务延时需求的方法也因场景的不同而不同。对于通信设备的位置信息相对固定和/或业务延时需求也相对固定的，通信设备可周期性向网络设备上报位置信息，可在触发业务时向网络设备发送业务延时需求，例如，公路上以相对固定速度移动和/或使相同的V2X业务的车辆。对于通信设备有多个业务延时需求的场景，例如通信设备同时激活了多个V2X业务，比如3ms的短时延业务，100ms的长时延业务，每次调度的业务延时需求可以不同，则通信设备可以在向网络设备发送调度请求的时候，将业务延时需求携带在调度请求中发送至网络设备。通信设备可在接收到网络设备发送的将位置信息携带在测量上报消息后，将位置信息发送至网络设备。如此，可提高网络设备确定通信设备组的精确度，且可以使得确定出的通信设备组中的各通信设备尽可能满足业务需求。
在上述步骤S301中，网络设备可根据目标通信设备组中通信设备的数量确定目标通信设备组的时间窗。通常，目标通信设备组中通信设备的数量越多，需要配置的时间窗越大。为了使得确定出的时间窗能尽量满足目标通信设备组中的各通信设备对业务延时需求，网络设备可根据目标通信设备组中通信设备的数量及各通信设备的业务延时需求确定目标通信设备组的时间窗。也就是说，在目标通信设备组中通信设备数量相同的情况下，通信设备组中各通信设备对业务延时需求小的目标通信设备组配置的时间窗较小，通信设备 组中各通信设备对业务延时需求大的目标通信设备组配置的时间窗较大，如此，可以满足通信设备组中各通信设备对业务的需求，例如，需要处理紧急业务的通信设备的时间窗较小，可以使得通信设备快速将紧急业务发送出去。
一种可能的实施方式中，当目标通信设备组中的通信设备的位置信息和/或业务延时需求发生变化后，或者当信道状态和通信设备周围干扰发生改变后，会造成网络设备确定出的目标通信设备组中至少两个通信设备的时间窗发生变化，因此，需要重新确定目标通信设备组的时间窗。结合上述图2，当网络设备确定通信设备201的位置信息从第一通信设备组移动到了第二通信设备组，则网络设备将变化后的通信设备201确定为第二通信设备组中通信设备，并需要重新确定变化后的第二通信设备组和变化后的第一通信设备组的时间窗。或者，网络设备确定通信设备的位置信息和业务延时需求均满足从第一通信设备组变化到了第二通信设备组，则网络设备将发生变化的通信设备确定为第二通信设备组中的通信设备，并重新确定变化后的第二通信设备组的时间窗和变化后的第一通信设备组的时间窗。或者，网络设备确定通信设备的周围干扰或者信道状态满足从第一通信设备组变化到第二通信设备组，则网络设备将发生变化的通信设备确定为第二通信设备组中的通信设备，并重新确定变化后的第二通信设备组和变化后的第一通信设备组的时间窗。
一种可能的实施方式中，时间窗包括N个时间单元，N个时间单元中包括K个第一时间单元和L个第二时间单元，其中，N为大于或等于2的整数，K为大于或等于1的整数，L为大于或等于1且小于等于(N-K)的整数。可选地，N个时间单元中包括的第一时间单元的数量和第二时间单元的数量的确定方式可为：N个时间单元中包括
Figure PCTCN2019091783-appb-000001
个第一时间单元和
Figure PCTCN2019091783-appb-000002
个第二时间单元，也就是说，K可确定为
Figure PCTCN2019091783-appb-000003
L可确定为
Figure PCTCN2019091783-appb-000004
也可以是N个时间单元中包括
Figure PCTCN2019091783-appb-000005
个第二时间单元和
Figure PCTCN2019091783-appb-000006
个第一时间单元，也就是说，L可确定为
Figure PCTCN2019091783-appb-000007
K可确定为
Figure PCTCN2019091783-appb-000008
本申请实施例中，K个第一时间单元和L个第二时间单元可以有不同的排列组合方式，以形成不同的样式。即，样式可以表示出一个时间窗中的N个时间单元中各时间单元是用于发送数据还是接收数据。一种可能的实施方式中，时间窗包括N个时间单元，可以形成的样式的数量可为
Figure PCTCN2019091783-appb-000009
可选地，在确定目标通信设备组的时间窗时，要满足确定出的时间窗可形成的样式的数量大于或等于目标通信设备组中通信设备的数量。如此，可以实现目标通信设备组中，一个通信设备对应一个样式，进而可以实现目标通信设备组中各通信设备的样式之间满足：任意一个通信设备在对应的样式的第一时间单元上发送的数据能被目标通信设备组中其它通信设备中的每个通信设备在对应的样式的第二时间单元中的至少一个第二时间单元上接收到。
表1示例性示出了本申请实施例提供的一种时间窗的时间单元数量与可形成的样式数量之间的关系。如表1所示，当时间窗包括2个时间单元时，可形成2个样式；当时间窗包括3个时间单元时，可形成3个样式；当时间窗包括4个时间单元时，可形成6个样式；当时间窗包括N个时间单元时，可形成
Figure PCTCN2019091783-appb-000010
个样式。
表1时间窗的时间单元的数量和可形成的样式的数量之间关系
Figure PCTCN2019091783-appb-000011
Figure PCTCN2019091783-appb-000012
一种可能的实施方式中，样式的数量可根据时间窗包括的时间单元数来确定，时间窗包括的时间单元数还可根据网络设备为目标通信设备组中通信设备配置的频域资源来确定。一种可能的实施方式中，第一指示信息还包括频域资源信息，例如信道的起始位置和长度、子信道的起始位置和长度、或资源块(resource block，RB)的起始位置和长度，以使第一通信设备根据时间窗和配置的频域资源通过所述侧行链路发送和接收数据。将第一指示信息中的频域资源指示至目标通信设备组中的至少两个通信设备的方式可与时间窗指示方式相同，比如通过在RRC信息或DCI信息中新增字段的方式，在此不再赘述。通过RRC信息中指示的频域资源信息为半静态的频域资源信息，通过DCI信息指示的频域资源信息为动态的频域资源信息，如果通信设备在DCI的调度授予信息中没有收到频域资源信息，可以使用RRC指示的频域资源信息通过侧行链路发送数据；如果在DCI调度授予信息中收到更新的频域资源信息，可以使用DCI指示的频域资源信息通过侧行链路发送数据。
对于目标通信设备组中的至少两个通信设备，当时间窗确定之后，对应的频域资源也可以确定；或者说，网络设备为通信设备配置的频域资源会对时间窗的确定有影响。也就是说，网络设备确定目标通信设备组的时间窗还与网络设备为目标通信设备组配置的频域资源相关。为了便于方案的说明，以20MHz系统带宽为例，网络设备配置子信道为4个RB，每个RB包括12个子载波，以15KHz的子载波间隔为例，则20MHz的系统带宽内一共可以有110个RB，共27个子信道，假设每个通信设备需要传输的数据大小可以承载在一个子信道中，27个子信道可以分别承载27个通信设备传输的数据，根据表1，则网络设备可确定目标通信设备组的时间窗包括7个时间单元；如果通信设备的数据大小需要2个子信道承载，27个子信道可以承载13个通信设备传输数据，根据表1，网络设备可确定目标通信设备组的时间窗包括6个时间单元。对于通信设备需要传输的数据大小差异比较大的场景，网络也可以根据每个通信设备需要传输的数据大小确定能同时调度的通信设备数量，进而确定目标通信设备组的时间窗包括的时间单元数。进一步，网络设备还可以获得传输信道状态信息，网络设备可根据通信设备需要传输的数据大小和传输信道信息确定能同时调度的通信设备数，进而确定出目标通信设备组的时间窗。
为了便于方案的理解，本申请实施例以时间窗包括3个时间单元(即N＝3)可形成的样式为例说明。时间窗包括3个时间单元，可形成的样式的数量为3个。时间窗为3个时间单元可形成的样式包括两种情况，第一种情况：
Figure PCTCN2019091783-appb-000013
即包括3个时间单元的时间窗中包括1个第一时间单元和2个第二时间单元，针对第一种情况的3种样式之间满足，任意一个样式的1个第一时间单元与其余2个样式中的每个样式的至少一个第二时间单元相对应。第二种情况：
Figure PCTCN2019091783-appb-000014
包括3个时间单元的时间窗中包括2个第一时间单元和1个第二时间单元，针对第二种情况的3种样式之间满足，任意一个样式的2个第一时间单元中的至少一个第一时间单元与其余2个样式中的 每个样式的1个第二时间单元相对应。可选地，第一时间单元可用1表示，第二时间单元可用0表示，则第一种情况形成的样式可表示为100、010和001。第二种情况形成的样式可表示为110、101和011。也就是说，当时间窗包括的时间单元的数量N为奇数时，可以形成的样式包括两种情况，对于目标通信设备组，分配给目标通信设备组中的至少两个通信设备的样式是其中任一种情况中形成的样式。
一种可能的实施方式中，当时间窗包括的N个时间单元中，N是偶数时，第一时间单元的数量和第二时间单元的数量相同。表2示例性示出了本申请实施例提供的一种时间窗包括8个时间单元时可形成的样式。如表2所示，包括8个时间单元的时间窗中包括4个第一时间单元和4个第二时间单元，第一时间单元用1表示，第二时间单元用0表示。当时间窗包括8个时间单元时，共可形成70种样式，70种样式之间满足，任意一个样式的4个第一时间单元中的至少一个第一时间单元与其余69个样式中的每个样式的至少一个第二时间单元相对应。
表2时间窗包括8个时间单元时可形成的样式
Figure PCTCN2019091783-appb-000015
一种可能的实施方式中，一个时间窗对应一个样式表。基于表1中的N个时间窗，可形成N个样式表。为了使网络设备快速确定出样式，以及减小网络设备向通信设备发送的数据量，网络设备可以对每个样式增加索引号，每个索引号可以唯一的确定出一个样式。一种可能的实施方式中，在各样式表中的各样式前可增加索引号。可选地，索引号的形式可为：N-m，其中N表示的是时间窗包括的时间单元对应的样式表，m表示的是该时间窗对应的样式表中的第m个样式，例如8-1中的8表示的是时间窗包括8个时间单元对应的样式表，1表示8个时间单元对应的样式表中的第一个样式；即索引号8-1表示的是时间窗包括8个时间单元对应的样式表中的第1个样式，可选地，可在表2中11110000前增加索引号8-1，以实现用索引号8-1指示出样式11110000。
基于表2所示的样式，图5(a)、图5(b)和图5(c)示例性示出了本申请实施例提供的三种不同样式的示意图。图5(a)、图5(b)和图5(c)中有阴影的表示第一时间单 元，第一时间单元用于发送数据；没有阴影的表示第二时间单元，第二时间单元用于接收数据。图5(a)所表示的样式可用11110000示意，四个第一时间单元均在四个第二时间单元的之前，即前四个第一时间单元均用于发送数据，后四个第二时间单元均用于接收数据。图5(b)所表示的样式可用10101100示意，第一个位置、第三个位置、第五个位置和第六个位置均为第一时间单元，第二个位置、第四个位置、第七个位置和第八个位置均为第二时间单元，也就是说，图5(b)所示的样式中位于第一、第三、第五和第六个位置的第一时间单元用于发送数据，位于第二、第四、第七和第八个位置的第二时间单元用于接收数据。如图5(c)所表示的样式可用01110010示意，位于第一、第五、第六和第八个位置的均为第二时间单元，位于第二、第三、第四和第七个位置的均为第一时间单元；也就是说，图5(c)所示的样式在第二、第三、第四和第七个位置的第一时间单元用于发送数据，在第一、第五、第六和第八个位置的第二时间单元用于接收数据。
本申请实施例提供了一种网络设备确定目标通信设备组中至少两个通信设备的样式的实施方式。所述网络设备可以根据所述目标通信设备组的至少两个通信设备的业务延时需求，确定所述至少两个通信设备的所述K个第一时间单元的位置；其中，业务延时越小的通信设备对应的样式中包括的第一时间单元在样式中的位置，相对于业务延时越大的通信设备对应的样式中包括的第一时间单元的位置越靠前。
结合图2、图5(a)、图5(b)和图5(c)，目标通信设备组以图2中的第一通信设备组为例。假设网络设备确定目标通信设备组中通信设备201、通信设备202和通信设备203的业务延时需求的关系为：通信设备201的业务延时小于通信设备202的业务延时、通信设备202的业务延时小于通信设备203的业务延时，则在图5(a)、图5(b)和图5(c)中，图5(a)和图5(b)所示样式的第一个第一时间单元位于第一个位置，图5(c)所示样式的第一个第一时间单元位于第二个位置，因此，图5(a)和图5(b)所示的样式的第一个第一时间单元位于图5(c)所示样式的第一时间单元之前。进一步，图5(a)所示样式的第二个第一时间单元在第二个位置，图5(b)所示的第二个第二时间单元在第三个位置，图5(a)所示样式的第二个第一时间单元位于图5(b)所示样式的第二个第一时间单元之前。因此，可将图5(a)所示的样式确定为通信设备201的样式，将图5(b)所示的样式确定为通信设备202的样式，将图5(c)所示的样式确定为通信设备203的样式。从图5(a)、图5(b)和图5(c)可以确定，在时间窗的第一个位置上，通信设备201和通信设备202用于发送数据，通信设备203用于接收数据，此时，通信设备203可以接收到通信设备201和通信设备202发送的数据，但是通信设备201和通信设备202工作在半双工模式(即在发送数据的时候不能接收数据，在接收数据的时候不能发送数据)，相互之间不能接收到对方发送的数据。在该时间窗的第二个位置上，通信设备201和通设备203用于发送数据，通信设备202是用于接收数据，此时，通信设备202可以接收到通信设备201发送的数据。在该时间窗的第五个位置上，通信设备201和通信设备203用于接收数据，通信设备202用于发送数据，此时，通信设备201可以接收到通信设备202发送的数据。因此，在一个时间窗内，通信设备202、通信设备202和通设备203相互之间均可以接收到彼此发送的数据。如此，在一个时间窗内，目标通信设备组中的各通信设备实现了全双工的效果。
进一步，目标通信设备组中的通信设备可以多次收到目标通信设备组中其它通信设备发送的数据，进而可提高目标通信设备组中通信设备的译码率。例如，通信设备201可以 在第五个位置和第六个位置的第二时间单元上两次接收到通信设备202发送的数据；通信设备202可以在第二个位置和第四个位置的第二时间单元上两次接收到通信设备201发送的数据；通信设备203可以在第一个位置、第五个位置和第六个位置上三次接收到通信设备202发送的数据，因此，通信设备201通过两次接收通信设备202发送的数据可提高对通信设备202发送的数据的译码率，通信设备202通过两次接收到通信设备201发送的数据可提高对通信设备201发送的数据的译码率，通信设备203通过三次接收通信设备202发送的数据可提高对通信设备202发送的数据的译码率。
本申请实施例中，网络设备确定出目标通信设备组中至少两个通信设备的各通信设备的样式后，网络设备向目标通信设备组中的至少两个通信设备发送第一指示信息，第一指示信息中包括至少两个的样式，所述至少两个样式中的每个样式分别由所述K个第一时间单元和所述L个第二时间单元组合形成、且所述至少两个样式中的每个样式的K个第一时间单元和L个第二时间单元组合形式不一样。一种可能的实施方式中，所述网络设备向第一通信设备发送第一样式，向第二通信设备发送第二样式，所述第一样式用于指示所述第一通信设备在所述第一样式中包括的K个第一时间单元上发送第一数据，所述第二样式用于指示所述第二通信设备在所述第二样式中包括的L个第二时间单元中的至少一个第二时间单元上接收所述第一数据，所述第一样式和所述第二样式均属于所述至少两个样式，所述第一通信设备和所述第二通信设备均属于所述目标通信设备组。
另一种可能的实施方式中，网络设备向目标通信设备组至少两个通信设备发送第一指示信息，第一指示信息中包括目标通信设备组中至少两个通信设备的样式，及与样式对应的通信设备的标识，以使目标通信设备组中的各通信设备确定各自对应样式。
一种可能的实施方式中，网络设备可预先存储有时间窗的时间单元数据量和可形成的样式的数量之间的关系表(如表1所示)、以及表1中各时间窗可形成的样式表，一个时间窗可对应一个可形成样式表，表2为其中一张表。网络设备确定出目标通信设备组中至少两个通信设备的样式后，将通信设备的样式携带在DCI消息或者RRC消息中发送至通信设备；或者，在通信设备中也可存储有和网络设备相同的表，预先存储可以通过预先配置来实现，也可以是通信设备在接入网络的时候，网络设备将本地存储的两种类型的表进行广播，通信设备将网络设备广播的两种类型的表存储在本地来实现，也可以是网络设备广播生成两种类型的表的规则，通信设备根据两种类型的表的生成规则生成的两种类型的表、并存储在本地来实现，本发明实施例这里并不做限定。
网络设备在确定出目标通信设备组中至少两个通信设备的样式时，网络设备可以将通信设备的样式对应的索引号携带在DCI消息或者RRC消息中发送至通信设备，例如，网络设备向通信设备发送的DCI消息或者RRC消息中携带的索引号为N-m，则通信设备可以根据N-m确定出是时间窗包括N个时间单元对应的样式表中的第m个样式。例如，通信设备接收到的索引号为8-1时，则通信设备可以根据8-1确定出是时间窗包括8个时间单元对应的样式表中的第1个样式，因此，通信设备可以确定出是上述表2中的样式11110000。通过发送样式的索引号可以减小网络设备向通信设备传输数据量，进而可节约空口资源。可选地，通信设备可根据样式的索引号可以唯一的确定出一个样式。可选地，通信设备中存储两种类型的表，则根据索引号可以确定出对应的时间窗以及该时间窗可形成的样式表。
本申请实施例中，网络设备确定出目标通信设备组中至少两个通信设备的样式后，网 络设备可以将目标通信设备组中通信设备的样式分多次指示给对应的通信设备。也就是说，针对一个通信设备要发送的数据，在一个时间窗内包括N个时间单元，N个时间单元中包括K个第一时间单元和L个第二时间单元，则网络设备可对该通信设备调度K次，即指示出K次使用K个时间单元发送数据，该通信设备在收不到指示发送数据的指示时，在K个时间单元中均用于接收数据。而且网络设备需要在DCI消息中携带一个指示信息，以指示出K个第一时间中，第一个第一时间单元是用于发送数据的时间单元，其余(K-1)个时间单元是重传第一个第一时间单元上已传输的数据的时间单元。这是因为通信设备在接收DCI消息时，不能确定出时间窗中用于新传或重传数据的时间单元，因此，DCI中需要指示用于新数据传输或用于重传数据传输的时间单元的标识，这样通信设备就可以清楚使用哪些时间单元传输新数据，哪些时间单元重传数据。
本申请实施例中，网络设备向通信设备组中的第一通信设备发送第一样式，向第二通信设备发送第二样式之后，第一通信设备接收第一样式，并在第一样式的第一时间单元上发送数据、在第一样式的第二时间单元上接收数据。第二通信设备接收第二样式，并在第二样式的第一时间单元上发送数据，在第二样式的第二时间单元上接收数据。图6示例性示出了本申请实施例提供的另一种数据传输方法流程示意图。该实施例中，当目标通信设备组为上述图2中的第一通信设备组时，则第一通信设备和第二通信设备为通信设备201、通信设备202和通信设备203中的两个。当目标通信设备组为上述图2中的第二通信设备组时，第一通信设备和第二通信设备为第二通信设备组的通信设备204和通信设备205。可选地，当网络设备仅调度第一通信设备组中的通信设备时，第二通信设备组中的各通信设备在监听并接收其它通信设备组发送的数据。当网络设备仅调度第二通信设备组中的通信设备时，第一通信设备组中的各通信设备在监听并接收其它通信设备组发送的数据。如图6所示，该方法包括：
步骤S601，第一通信设备在第一通信设备的所述第一样式中包括的K个第一时间单元上发送第一数据和/或第二指示信息。其中，所述第二指示信息用于指示所述第一样式中包括的发送所述第一数据的当前第一时间单元在所述第一样式中包括的K个第一时间单元中的位置。
一种可能的实施方式中，第一通信设备在物理下行控制信道(physical downlink control channel，PDCCH)上接收网路设备对该第一通信设备在侧行链路上发送和接收数据的调度授予信息之后，第一通信设备根据调度授予信息生成调度分配(scheduling assignment，调度分配SA)信息。为了减小第一通信设备发送的数据量，第二指示信息可以在SA中新增的一个字段，该新增的字段可以指示出发送第一数据的当前第一时间单元在第一样式中包括的K个第一时间单元中的位置，一种可能的实施方式为指示出发送第一数据的当前第一时间单元是否为K个第一时间单元中的最后一个位置的第一时间单元。可以用1个比特位指示，例如用1表示是该样式中非最后一个第一时间单元，用0表示是该样式中最后一个第一时间单元。另一种可能的实施方式中，第一通信设备可以在发送第一数据的时候一起发送第二指示信息。
一种可能的实施方式中，第一通信设备在侧行链路上，在所述第一样式中包括的K个第一时间单元中的每个第一时间单元中重复发送相同的第一数据；其中，相同的第一数据可以是编码后的相同数据，也可以是独立译码的同一数据的不同编码版本。
步骤S602，第二通信设备在所述第二通信设备的第二样式中包括的K个第一时间单 元上发送第二数据和/或第三指示信息。其中，所述第三指示信息用于指示所述第二样式中包括的发送所述第二数据的当前第一时间单元在第二样式中包括的K个第一时间单元中的位置，第三指示信息也可以是在SA中新增的一个字段，添加的方式可以与第二指示信息的添加方式相同，在此不再赘述。
一种可能的实施方式中，第二通信设备在侧行链路上，在所述第二样式中包括的K个第一时间单元中的每个第一时间单元中重复发送相同的第二数据；其中，相同的第二数据可以是编码后的相同数据，也可以是独立译码的同一数据的不同编码版本。
上述步骤S601和步骤S602没有先后顺序，先执行步骤S601还是步骤S602根据第一通信设备和第二通信设备的样式确定。所述第一样式中的K个第一时间单元的位置是根据所述第一通信设备的业务延时需求确定的；所述第二样式中的K个第一时间单元的位置是根据所述第二通信设备的业务延时需求确定的；其中，针对所述目标通信设备组中的至少两个通信设备，业务延时小的通信设备对应的样式中包括的第一时间单元位于业务延时大的通信设备对应的样式中包括的第一时间单元之前。当第一通信设备对应的第一样式中的第一时间单元的位置在所述第二通信设备对应的第二样式中的第一时间单元的位置之前时，先执行步骤S601。否则，先执行步骤S602。
步骤S603，第二通信设备在第二通信设备的第二样式中包括的L个第二时间单元中的至少一个第二时间单元上接收第一通信设备发送的第一数据和/或第二指示。
步骤S604，第一通信设备在第一通信设备的第一样式中包括的L个第二时间单元中的至少一个第二时间单元上接收第二通信设备发送的第二数据和/或第三指示信息。
可选地，第二通信设备对接收到的第一数据和/或第二指示信息的处理方式与第一通信设备对接收到的第二数据和/或第三指示信息的处理方式相同，为了便于说明，下述步骤S603至步骤S608以第一通信设备示例性地例说明。
上述步骤S603和步骤S604没有先后顺序，先执行步骤S603还是步骤S604根据第一通信设备和第二通信设备的样式确定。确定了第一通信设备的第一样式中包括的K个第一时间单元的位置之后，即可确定出第一通信设备的第一样式中包括的L个第二时间单元的位置；确定了第二通信设备的第二样式中包括的K个第一时间单元的位置之后，即可确定出第二通信设备的第二样式中包括的L个第二时间单元的位置。当第一通信设备对应的第一样式中的第二时间单元的位置在所述第二通信设备对应的第二样式中的第二时间单元的位置之前时，先执行步骤S604。否则先执行步骤S603。
步骤S605，第一通信设备对接收到的第二数据进行译码，并确定是否译码成功；当译码失败时，执行步骤S606；当译码成功时，执行步骤S609。
一种可能的实施方式中，当译码成功时，忽略第一样式中包括的当前第二时间单元之后的第二时间单元上接收到的第二数据；其中，第一样式中包括的当前第二时间单元为用于发送译码成功的第二数据对应的第一样式中包括的一个第二时间单元。
步骤S606，第一通信设备根据第二指示信息确定所述第三指示信息指示的所述第二样式中包括的当前第一时间单元的位置是否为所述第二样式中包括的K个第一时间单元中的最后一个；若否，则执行步骤S607；若是，则执行步骤S610。
一种可能的实施方式中，第一通信设备可根据第二通信设备发送的SA中新增的字段确定所述第三指示信息指示的所述第二样式中包括的当前第一时间单元的位置是否为所述第二样式中包括的K个第一时间单元中的最后一个，比如确定新增的字段为1，则表示 非第一样式的最后一个第一时间单元；确定为0，则表示是第一样式中最后一个第一时间单元。
步骤S607，第一通信设备接收所述第二通信设备在所述第二样式中包括的后一个第一时间单元上发送的所述第二数据。其中，所述后一个第一时间单元为所述第二样式中包括的K个第一时间单元中位于所述第三指示信息指示的所述第二样式中包括的当前第一时间单元之后的一个第一时间单元。
步骤S608，第一通信设备对两次接收到的所述第二数据合并译码，并确定合并译码是否成功；当合并译码失败时，重复执行步骤S606至S607，或者，直至译码成功或者确定用于发送所述第二数据的所述第二样式中包括的当前第一时间单元的位置是所述第二样式中包括的K个第一时间单元中的最后一个为止；当合并译码成功时，执行步骤S609。
可选地，第一通信设备通过对两次接收到的第二数据合并译码，可提高对第二数据译码的成功率。
步骤S609，第一通信设备将译码成功的数据传输至层二及以上层进行处理。
步骤S610，流程结束。
