Abstract: An apparatus for receiving a signal through an unlicensed band includes: a processor, a memory, and a radio frequency unit, wherein the processor executes a program stored in the memory to perform: receiving a secondary synchronization signal (SSS) in at least one remaining subframe except a subframe 0 or a subframe 5 of a plurality of subframes included in a discovery signal measurement timing configuration (DMTC), and detecting the SSS by using a subframe number of the subframe 0 or the subframe 5.

Abstract: A method in which a base station transmits a CSI (channel state information)-RS (reference signal) in a MIMO (multiple input multiple output) antenna system is provided. The base station periodically transmits a CSI-RS for first CSI to a terminal. The base station requests the terminal to transmit second CSI in a first subframe. When a CSI-RS occasion is configured, the base station transmits a CSI-RS for the second CSI to the terminal for a duration of the CSI-RS occasion from a second subframe or to the second subframe, which is a subframe after a first offset configured for CSI-RS transmission from the first subframe.

Abstract: A base station includes a plurality of first resource elements (REs) corresponding to at least two of a second orthogonal frequency division multiplexing (OFDM) symbol, a third OFDM symbol, and a fourth OFDM symbol of a first time slot, in a first CSI-RS resource pool configured in a first subframe including the first time slot and a second time slot subsequent to the first time slot. Furthermore, the base station transmits a CSI-RS at least one of REs included in the first CSI-RS resource pool.

Abstract: A method for synchronization by a D2D terminal in a D2D communication network through receiving a first D2D synchronization signal from at least one D2D synchronization source and performing synchronization according to a synchronization timing reference provided through the first D2D synchronization signal, and a method for negotiating whether to perform a role as a synchronization source with another D2D synchronization source through determining, when a D2D synchronization signal and a D2D synchronization channel are received from at least one D2D synchronization source, whether to maintain a role as the independent synchronization source based on negotiation information for negotiation between synchronization sources included in the D2D synchronization channel, and operating as a relaying synchronization source when the role as the independent synchronization source is not maintained, are provided.

Abstract: A communication method for a third device that controls a first link established directly between a first device and a second device is provided. The third device allocates a first link identifier for identifying the first link. The third device transmits first information including the first link identifier to the first device and the second device. The third device receives, from the first device and the second device, second information including allocation acceptance information indicating the acceptance or rejection of allocation of the first link identifier.
