其中，同步信号可以包括时钟信息(发送时钟)和标识(Identity，简称为“ID”)信息。由此，发送终端和接收终端接收到对方发送的同步信号时，可以获得对方的时钟信息和标识信息，这样发送终端和接收终端可以完成同步，该同步的过程可以参见现有技术中关于同步的描述，本发明实施例不再赘述。

具体地，基站在接收到发送终端发送的针对接收终端的资源调度请求后，基站通过与该接收终端之间的AI1配置该接收终端上报从发送终端到该接收终端的信道状态信息，并且可选地，基站通过AI1配置该接收终端上报对发送终端针对该接收终端的发送时钟调整信息和功率控制信息。
可选地，基站可以在CSI配置信息中指示该接收终端具体是上报哪个发送终端到该接收终端的信道的CSI，并可以通过该CSI配置信息指示该接收终端用于上报该CSI的资源。CSI可以包括下列信息中的至少一种：秩指示 符(RankIndicator，简称为“RI”)、预编码矩阵索引(Precoding Matrix Index，简称为“PMI”)、信道质量指示符(Channel Quality Indicator，简称为“CQI”)。

可选地，基站可以在S107中将发送终端用于重传的资源分配给发送终端，将接收终端用于接收重传数据的资源分配给接收终端，此时，在S110中，基站不需要再进行资源分配，仅需要指示发送终端在之前分配的资源上进行重传以及接收终端在之前分配的资源上接收重传数据即可。
S112，发送终端向接收终端发送重传数据。
同时，接收终端在分配的资源上接收该发送终端发送的重传数据。
应注意，图3中的流程的序号并不一定代表流程执行的顺序，例如，S103可以在S101和S102之前执行，具体的执行顺序是由各个步骤之间的逻辑关系所体现的。
图3中所示的端到端传输数据的方法中，信道测量、重传、时钟调整、功率控制由基站进行集中控制，由此端到端链路进一步简化为只传输同步信号、广播信道和数据。在基站覆盖范围内(In Coverage场景)，本发明实施例的传输数据的方法能够进一步简化终端的复杂度，提高调度和控制的准确性和可靠性。
