Description

一种数据传输方法、装置以及存储介质 技术领域
本申请涉及通信技术领域，具体涉及一种数据传输方法、装置以及存储介质。
背景技术
无线通信技术在过去几十年经历了飞速的发展，无线通信系统支持的业务也从最初的语音、短信，发展到现在支持无线高速数据通信。与此同时，全世界范围内的无线连接数量正在经历持续地高速增长，各种新的无线业务类型也大量涌现，例如物联网、自动驾驶等，这些都对下一代无线通信系统，也即第五代(5rd-generation，5G)无线通信系统，提出了更高的要求。
用户协作是下一代通信系统主要支持的特性之一，其可以显著提高系统的容量以及网络的覆盖范围，同时可以降低基站端的负载。基站给目标终端设备(target user equipment，TUE)发送数据包时，和TUE处于同一个协作组的协作终端设备(cooperation user equipment，CUE)也能进行接收和尝试解码。如果CUE解码成功，会将数据包通过侧行链路转发TUE，从而提升TUE的接收性能。基于用户协作的传输主要包含两个阶段：第一阶段，基站发送数据给目标终端设备以及与TUE属于同一个用户协作组的CUE；第二阶段，CUE将正确接收到的信号通过侧行链路转发给TUE(可以有不同的转发方式，如放大转发、解码转发或压缩转发等)。这样，TUE可以将第一阶段接收到的基站发送的信号和第二阶段收到的CUE的转发信号联合起来进行解码，从而提升接收性能。
在一种用户协作的现有技术中，基站先给CUE和TUE发送同一个数据包，同时基站设置了一个定时器T0，在T0内，基站预配置了CUE将数据包转发给TUE的侧行链路的时频资源，以及承载TUE反馈给基站、CUE的混合自动重传确认信息(hybrid automatic repeat request-acknowledgment，HARQ-ACK),其中，HARQ-ACK也可以简称为ACK。如果TUE接收正确，就反馈ACK，否则不反馈。基站在给TUE和CUE发送数据之后，开始计时，包含如下几种情况：(1)如果TUE接收正确，则TUE会会反馈ACK，告知CUE和基站接收正确，下行传输结束；(2)如果CUE已经正确接收到数据包，且TUE接收错误，则TUE不反馈任何消息，此时CUE没有检测到TUE的反馈，直接在侧行连路上发起转发操作，将数据包转发给TUE；(3)当计时小于TO时，若TUE接收错误，则重复(2)中的步骤，直到TUE接收正确，按照(1)中的操作，结束下行传输；(4)若计时等于T0时，则基站发起重传，将数据包重新发送给CUE和TUE，计时重新开始。
上述流程存在一个问题，如果CUE收错，TUE也收错了，则在T0的时间段内，CUE不会将数据包转发给TUE，基站无法知道CUE是否发起转发操作，基站认为之前分配给CUE和TUE用来转发的侧行时频资源是被占用的，这将导致侧行时频资源被浪费长达T0的时间。

图2为本申请实施例所提供的数据传输方法的一个实施例示意图。
参阅图2，本申请实施例所提供的数据传输方法的一个实施例，可以包括：
201、网络设备发送定时信息和下行数据，其中，定时信息的目的端包括第一终端，下行数据的目的端为第二终端。
本申请实施例中，网络设备首先发送定时信息和下行数据。其中，该定时信息的目的端包括第一终端，下行数据的目的端为第二终端。可选地，定时信息的目的端还可以包含第一终端。
本申请实施例中，网络设备为第一终端，或者为第一终端和第二终端配置定时信息。对于第一终端，在该定时信息所指示的定时时间内，当目的端为第二终端的下行数据被第一终端成功接收，则第一终端会在该定时时间内通过预先配置的侧行时频资源将该下行数据自动转发给第二终端。对于第二终端，在该定时信息所指示的定时时间内，会在侧行时频资源上接收第一终端转发的下行数据。
需要说明的是，本申请实施例中，定时信息和下行数据可以是同时通过同一个信息或不同信息发送的，也可以是通过不同的信息分别进行发送，可以是先发送定时信息再发送下行数据，也可以是先发送下行数据再发送定时信息，本申请实施例对此均不作限定。
202、网络设备接收第一终端在定时时间内发送的第一反馈信息，其中，定时时间是第一终端根据定时信息确定的，第一反馈信息是第一终端根据第二终端发送的第二反馈信息和所述第一终端对下行数据的接收结果确定的，第二反馈信息用于指示第二终端对下行数据的接收结果。
本申请实施例中，网络设备在将定时信息和下行数据发送出去之后，会接收第一终端在定时时间内发送的第一反馈信息。
本申请实施例中，第一反馈信息是第一终端在接收到第二终端发送的第二反馈信息后，根据该第二反馈信息和第一终端对下行数据的接收结果确定的。本申请实施例中，第二终端向第一终端发送的第二反馈信息用于指示第二终端对下行数据的接收结果。本申请实施例中，第一反馈信息用于指示第一终端对下行数据的接收结果以及第二终端对下行数 据的接收结果。
需要说明的是，本申请实施例中，第一终端或第二终端对于下行数据的接收结果分为两种：第一，接收结果为成功，是指第一终端或第二终端成功接收下行数据，并对该下行数据成功解码；第二，接收结果为失败，是指第一终端或第二终端没有接收到下行数据，或者接收到该下行数据但对该下行数据解码失败。
本申请实施例中，网络设备在分别向第一终端和第二终端发送定时信息以及下行数据之后，能够接收到第一终端在定时信息所指示的定时时间内发送的反馈信息，该反馈信息用于指示第一终端和第二终端对下行数据的接收结果，使得当第二终端对该下行数据接收失败，且第一终端也对该下行数据接收失败无法成功转发时，网络设备能够及时确定第一终端是否发起转发操作，并进行及时处理，从而避免侧行时频资源的浪费。
图3为本申请实施例提供的数据传输方法的另一个实施例示意图。
参阅图3，本申请实施例所提供的数据传输方法的另一个实施例，可以包括：
301、网络设备发送定时信息和下行数据，该定时信息的目的端包括第一终端，下行数据的目的端为第二终端。
本申请实施例可以参阅图2中的步骤201进行理解，此处不再赘述。
302、网络设备向第一终端发送配置信息，该配置信息包括时频资源的配置信息。
本申请实施例中，网络设备会想第一终端发送配置信息，该配置信息包括时频资源的配置信息，该时频资源用于第一终端向网络设备发送反馈信息。
本申请实施例中的配置信息可以是通过物理层信令或高层信令配置的，还可以是通过协议预定义配置，本申请实施例对此不作限定。可选地，本申请实施例中，该时频资源的配置方法可以是通过配置物理上行控制信道(physical uplink control channel，PUCCH)的现有技术进行，本申请实施例在此处不进行赘述。
可选地，本申请实施例中的配置信息还可以包括侧行时频资源的配置信息。当目的端为第二终端的下行数据被第一终端成功接收时，第一终端通过侧行时频资源向第二终端转发下行数据，或者通过该侧行时频资源接收第二终端反馈的信息。
需要说明的是，本申请实施例对步骤301和步骤302的先后顺序不作具体的限定。即本申请实施例中，网络设备可以是同时发送定时信息、下行数据以及配置信息，也可以是分开发送的，当分开发送时，本申请实施例对定时信息、下行数据、配置信息的发送顺序不作具体的限定。
303、第二终端向第一终端发送的第一反馈信息，该第一反馈信息用于指示第二终端对下行数据的接收结果。
本申请实施例中，在网络设备发送定时信息和下行数据之后，第二终端会向第一终端发送第一反馈信息，该第一反馈信息用于指示第二终端对下行数据的接收结果。
本申请实施例中，第二终端对下行数据的接收结果包括成功和失败两种，接收结果为成功是指第二终端成功接收下行数据并对该下行数据解码成功，接收结果为失败是指第二终端没有接收到下行数据，或者接收到该下行数据但解码失败。
可选地，本申请实施例中当第二终端对下行数据的接收结果为成功时，第二终端向第 一终端发送第一反馈信息可以是在侧行时频资源上反馈ACK信息，当第一终端接收到第二终端发送的ACK信息后，确认第二终端对下行数据的接收结果为成功。
可选地，本申请实施例中当第二终端对下行数据的接收结果为失败时，第二终端向第一终端发送第一反馈信息可以是在侧行时频资源上反馈NACK信息，当第一终端接收到第二终端发送的NACK信息后，确认第二终端对下行数据的接收结果为失败。
可选地，本申请实施例中当第二终端对下行数据的接收结果为失败时，第二终端向第一终端发送第一反馈信息可以是在侧行时频资源上不反馈任何信息，当第一终端在侧行时频资源上没有检测到第二终端的任何反馈时，确认第二终端对下行数据的接收结果为失败。
304、第一终端根据第一反馈信息和第一终端对下行数据的接收结果确定第二反馈信息，该第二反馈信息用于指示第一终端对下行数据的接收结果和第二终端对下行数据的接收结果。
本申请实施例中，第一终端在接收到第二终端发送的第一反馈信息后，根据该第一反馈信息和第一终端对下行数据的接收结果确定第二反馈信息，该第二反馈信息用于指示第一终端对下行数据的接收结果和第二终端对下行数据的接收结果。本申请实施例中，第一终端对下行数据的接收结果也包括成功和失败两种，接收结果为成功是指第一终端成功接收下行数据并对该下行数据解码成功，接收结果为失败是指第一终端没有接收到下行数据，或者接收到该下行数据但解码失败。
305、第一终端在定时时间内向网络设备发送第二反馈信息。
本申请实施例中，第一终端在根据第一反馈信息和第一终端对下行数据的接收结果确定第二反馈信息之后，在定时时间内通过配置信息所指示的时频资源向网络设备发送第二反馈信息。
可选地，本申请实施例中的第二反馈信息可以是通过目标比特或者目标序列的有无表示。例如，第二反馈信息可以通过一个比特进行表示，该一个比特的取值为“1”时，表示第一终端和第二终端对下行数据的接收结果均为失败，当该一个比特的取值为“0”时，表示第一终端对下行数据的接收结果为成功，第二终端对下行数据的接收结果为失败。网络设备接收第二反馈信息后，根据该一个比特的取值，确定第一终端和第二终端对下行数据的接收结果。例如，第二反馈信息可以通过一个目标序列的有无进行表示，该目标序列存在时，表示第一终端和第二终端对下行数据的接收结果均为失败，当该目标序列不存在时，表示第一终端对下行数据的接收结果为成功，第二终端对下行数据的接收结果为失败。网络设备接收第二反馈信息后，根据该目标序列的有无，确定第一终端和第二终端对下行数据的接收结果。
306、网络设备根据第二反馈信息，确定定时时间是否有效。
本申请实施例中，网络设备接收第一终端发送的第二反馈信息之后，根据该第二反馈信息可以确定第一终端和第二终端对下行数据的接收结果，并根据第一终端和第二终端对下行数据的接收结果确定定时时间是否有效。
本申请实施例中，当第一终端和第二终端对下行数据的接收结果均为失败时，第二终端没有成功接收下行数据，第一终端无法完成该下行数据的转发，第一终端所配置的定时 时间失效，若第一终端预先进行了侧行时频资源的配置，则该侧行时频资源也失效。因此网络设备可以根据第一终端发送的第二反馈信息确定定时时间失效，需要进行下行数据的重传。可选地，网络设备还可以根据第二反馈信息确定所配置的侧行时频资源也失效。
本申请实施例中，当第一终端对下行数据的接收结果为成功，第二终端对下行数据的接收结果为失败时，第一终端能够完成下行数据的转发，第一终端所配置的定时时间有效，若第一终端预先进行了侧行时频资源的配置，则该侧行时频资源也有效。因此，网络设备可以根据第一终端发送的第二反馈信息确定定时时间有效，第一终端将继续尝试完成转发，网络设备确定不需要进行下行数据的重传。可选地，网络设备还可以根据第二反馈信息确定所配置的侧行时频资源也是有效的。
可选地，本申请实施例中，当第一终端对下行数据的接收结果为成功，第二终端对下行数据的接收结果为失败时，第一终端也可以不在所配置的时频资源上反馈任何信息，此时，网络设备若没有在该时频资源上检测到任何信息，也可以确定定时时间有效，第一终端将继续尝试完成转发，网络设备确定不需要进行下行数据的重传。可选地，所配置的侧行时频资源也是有效的。
本申请实施例中，网络设备在分别向第一终端和第二终端发送定时信息以及下行数据之后，能够接收到第一终端在定时信息所指示的定时时间内通过预先配置的时频资源发送的反馈信息，该反馈信息用于指示第一终端和第二终端对下行数据的接收结果，使得当第二终端对该下行数据接收失败，且第一终端也对该下行数据接收失败无法成功转发时，网络设备能够及时确定第一终端无法完成转发操作，确定定时时间失效，从而避免侧行时频资源的浪费。
