Abstract: The present application discloses a method for enabling a terminal to transceive a signal with a base station in a TDD (Time Division Duplex) communications system. Specifically, the method includes the steps of: receiving reference sub-frame set information through the system information and active sub-frame set information through dynamic signaling; receiving an uplink grant for transmitting an uplink signal in a downlink sub-frame defined in the active sub-frame set information; judging the effectiveness of a particular uplink sub-frame for transmitting the uplink signal commanded by the uplink grant; and transmitting the uplink signal to the base station if the particular uplink sub-frame is effective.

Abstract: A method and apparatus for performing contention resolution for contention based physical uplink shared channel (CB-PUSCH) transmission in a wireless communication system is provided. A user equipment (UE) performs a first hybrid automatic repeat request (HARQ) transmission on a CB-PUSCH to a network, and determines whether contention on the CB-PUSCH is resolved. The CB-PUSCH is a channel for UL data allocated by a pre-configured UL grant which is shared by multiple UEs. If a UL grant includes an identity of the UE, it is determined that contention on the CB-PUSCH is resolved. The UE may perform a second HARQ transmission for the first HARQ transmission on a PUSCH to the network by using the UL grant.

Abstract: The present invention relates to a method and an apparatus for transmitting a device-to-device (D2D) synchronization signal of a first terminal in a wireless communication system. Specifically, the method comprises the steps of: receiving a radio resource setting for D2D communication; and transmitting a D2D synchronization signal to a second radio resource which corresponds to a specific index, other than a first radio resource, from among a plurality of radio resource setting-based D2D radio resources, wherein the first radio resource is defined to be used for wide area network (WAN) based communication.
