Instruction method for transmitting physical control channel and device thereof

The invention relates to an indication method for transmitting a physical control channel and a device thereof. The method comprises the following steps of determining one of a space-frequency block code SFBC and a unicast as a receiving mode for user equipment to receive a downlink physical control channel by a wireless node; sending an indication message to the user equipment by the wireless node, wherein the indication message is used for indicating that the user equipment receives the downlink physical control channel sent by the wireless node by adopting the above receiving mode. The receiving mode of the downlink physical control channel sent by the wireless node is determined for the user equipment by the wireless node, and then the receiving mode is sent to the user equipment. Therefore, the user equipment can receive the downlink physical control channel according to the receiving mode, and the system performance is improved.
