Abstract: A discovery method for device to device communication between terminals is disclosed. The discovery method for the device to device communication between terminals comprises the steps of: performing transmission in a first sub-frame; transmitting a discovery channel through a preset section in a second sub-frame located next to the first sub-frame; and performing transmission in a third sub-frame next to the second sub-frame. Therefore, the present invention can transmit and receive the discovery channel without colliding with other data.

Abstract: Provided is a communication system that transmits a control channel using a downlink. The communication system may transmit, to the terminal, transmission information of uplink allocation information that indicates whether uplink allocation information is transmitted using a downlink, and the terminal may determine whether the uplink allocation information is included in a downlink frame, based on the transmission information of uplink allocation information. The base station may transmit, to the terminal, information associated with a resource which has a possibility of being used for transmission of a physical downlink control channel (PDCCH), and the terminal may decode the PDCCH in the resource which has a possibility of being used for transmission of the PDCCH.

Abstract: Disclosed is a method for transmitting and receiving control information. The method for transmitting control information according to the present invention, in a mobile communication system in which a control channel region and a data channel region are separated from each other, comprises the steps of: determining a control channel resource for transmitting control information by means of the data channel region; and transmitting the control information using the determined control channel resource. According to the present invention, a capacity for control information, which increases for multiple user multiple-input multiple-out (MIMOs) in a heterogeneous network environment, for heterogeneous network interference control using carrier aggregation, for frequent use of a multicast-broadcast single frequency network (MBSFN) subframe, and for a CoMP transmission control, may be satisfied. Further, an adaptive resource allocation based on a requested capacity for control information may be enabled, and the efficient utilization of resources may also be enabled.
