摘要： A control information transmission method and a control information receiving terminal are provided. The transmission method comprises: notifying a terminal of setting information of control information in a downlink subframe (S202); and transmitting the control information to the terminal in a preset subframe and other subframes determined according to the setting information (S204). By transmitting the control information on part of the 16m subframes and notifying the 16m terminal of the information of setting the control information, the present invention enables the 16m terminal to shut down the RF transmission at the location of a subframe where the control information is not included and no resource related to the terminal is assigned, and to enter the micro sleep mode, which reduces power consumption of the terminal.
