Abstract: The present invention relates to a wireless communication system. Particularly, the present invention relates to a method for transmitting control information and an apparatus therefor, the method comprising the steps of: generating a PUCCH for transmitting the control information; and transmitting the PUCCH from a subframe having a plurality of symbols, wherein the PUCCH is transmitted from an Mth symbol (M>N) of the subframe when a downlink control channel is transmitted to first N (N>0) number of symbols of the subframe, and the PUCCH is transmitted from a first symbol of the subframe when the downlink control channel is not transmitted to the subframe.

Abstract: Disclosed is a method for determining, by a terminal, a transmission resource pool in device-to-device (D2D) communication. The method for determining a transmission resource pool comprises the steps of: indexing resource blocks within a resource block pool; and mapping the indexed resource blocks to physical resource blocks, wherein the indexed resource blocks are arranged in order of increasing resource block index, the resource block pool is used to transmit D2D signals, and information about the configuration of the resource block pool can be indicated by upper layer signaling.
