本公开实施例提供了一种下行控制信道的接收方法，可以用于终端。可选地，所述下行控制信道是用于传输公共控制信息的下行的控制信道，例如PDCCH。参照图1根据一示例性实施例示出的一种下行控制信道的接收方法流程图，可以包括以下步骤：
在步骤101中，确定用于接收所述下行控制信道的目标接收方式；

上述实施例中，终端可以先确定用于接收下行控制信道的目标接收方式，进而按照所述目标接收方式接收基站发送的所述下行控制信道。通过上述过程，实现了由终端按照目标接收方式接收下行控制信道的目的，提升了5G系统的性能。
针对上述步骤101，可选地，终端可以采用以下至少一种方式确定所述目标接收方式。

本步骤中，所述终端可以根据表1或表2直接将与所述目标关联信息对应的接收方式作为所述目标接收方式。
当然，在本公开实施例中，所述终端还可以采用以上三种方式两两结合来确定所述目标接收方式，例如将目标接收方式中的一部分通过通信协议预先定义，剩余的通过目标信令由基站发送给终端。或者也可以同时使用上述三种方式来确定所述目标接收方式。
上述实施例中，终端在确定目标接收方式时，可以基于终端与基站之间的通信协议，将与下行控制信道对应的预设接收方式作为所述目标接收方式；或者可以接收所述基站通过目标信令发送的所述目标接收方式；或者还可以在确定与所述下行控制信道关联的目标关联信息后，根据预存的接收方式与关联信息之间的对应关系，将与所述目标关联信息对应的接收方式作为用于接收所述下行控制信道的目标接收方式。通过上个过程，终端可以确定用于接收下行控制信道的目标接收方式，实现简便，可用性 高。
