下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的控制信令的传输方法和设备进行详细地说明。
如图2所示，本申请的一个实施例提供一种控制信令的发送方法200，该方法可以由网络侧设备执行，换言之，该方法可以由安装在网络侧设备的软件或硬件来执行，该方法包括如下步骤。
S202：发送控制信令，该控制信令用于指示中间节点执行如下至少之一：接收来自于网络侧设备的第一消息并将第一消息转发给终端；接收来自于终端的第二消息并将第二消息转发给网络侧设备。
本申请实施例中提到的中间节点可以是层一(物理层)中继，基于上述控制信令，中间节点可以接收第一/第二消息并放大后转发，如，接收来自于网络侧设备的第一消息并将第一消息转发给终端；接收来自于终端的第二消息并将第二消息转发给网络侧设备。
在一个例子中，上述控制信令用于指示中间节点接收和/或转发第一消息的时域位置。例如，上述控制信令用于指示中间节点接收第一消息的时域位置；指示中间节点转发第一消息(即向终端发送第一消息)的时域位置；同时指示中间节点接收和转发第一消息的时域位置。
在另一个例子中，上述控制信令用于指示中间节点接收和/或转发所述第二消息的时域位置，例如，上述控制信令用于指示中间节点接收第二消息的时域位置；还可以用于指示中间节点转发第二消息(即向网络侧设备发送第二消息)的时域位置；还可以用于同时指示中间节点接收和转发第二消息的时域位置。
可以理解，上述两个例子在实施时并不存在冲突的而地方，因此，上述两个例子可以同时实现，即上述控制信令可以用于指示中间节点接收和/或转发第一消息的时域位置，同时用于指示中间节点接收和/或转发第二消息的时域位置。
可选地，上述多个例子中提到的控制信令，除了可以用于指示时域位置之外，还可以用于指示波束信息。
在一个例子中，上述控制信令用于指示所述中间节点接收和/或转发所述第一消息的波束信息。具体例如，上述控制信令可以用于指示所述中间节点接收第一消息的波束信息；还可以用于指示所述中间节点转发(即向终端发送第一消息)第一消息的波束信息；还可以用于同时指示中间节点接收和转发所述第一消息的波束信息。
在另一个例子中，上述控制信令用于指示所述中间节点接收和/或转发所述第二消息的波束信息。具体例如，上述控制信令可以用于指示所述中间节点接收第二消息的波束信息；还可以用于指示所述中间节点转发(即向网络侧设备发送第二消息)第二消息的波束信息；还可以用于同时指示中间节点接收和转发所述第二消息的波束信息。
同理，上述两个例子在实施时并不存在冲突的而地方，因此，上述两个例子可以同时实现，即上述控制信令可以用于指示中间节点接收和/或转发第一消息的波束信息，同时用于指示中间节点接收和/或转发第二消息的波束信息。
基于上述几个实施例介绍的控制信令所指示的波束信息，本申请实施例提供的控制信令的发送方法还可以应用在毫米波(FR2)频段，使得中间节点可以通过较窄的波束进行消息的接收和转发，实现更精准的消息转发功能，提高通信效率。
更进一步地，本申请实施例中提到的中间节点可以是层一(物理层)中继，该层一中继无需自主决策(如波束信息、时域位置等)，完全基于上述控制信令进行消息的接收和转发，便于节约中间节点的设计成本。
本申请实施例提供的控制信令的发送方法，网络侧设备向中间节点发送控制信令，该控制信令用于指示中间节点执行如下至少之一：接收来自于网络侧设备的第一消息并转发给终端；接收来自于终端的第二消息并转发给网络侧设备，进而实现了网络侧设备对中间节点的精确控制，使得中间节点可以准确地进行消息转发，提高通信效率。
更进一步地，上述控制信令还可以用于指示中间节点接收和/或转发第一 消息/第二消息的时域位置、波束信息等，使得中间节点可以确定消息的时域位置以及收发波束，进而使得中间节点准确地进行消息转发，提高通信效率。
本申请实施例提供的控制信令的发送方法的应用场景可以参见图3，在图3中，对于下行过程，网络侧设备可以通过某一波束向中间节点发送第一消息(图3中的PDCCH-R，该处R代表中继)，中间节点可以通过某一波束将第一消息转发给终端，上述波束信息以及第一消息的时域位置均可以通过控制信令指示，上述控制信令可以是网络侧设备预先发送给中间节点。图3中的上行过程与下行过程类似，在此不再描述。
为详细说明本申请实施例提供的控制信令的发送方法，以下将结合几个具体的实施例进行说明。
