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 beamforming apparatus and method for expanding coverage of a control channel are provided, by which neighboring communication devices are classified according to the number of beams that they can receive, and therefore the frequency or period of beam transmission is adjusted to transmit a control channel by a beamforming method. Hence, an overhead reduction and an increase in transmission rate can be achieved, and coverage holes can be prevented.

Abstract: A method for a first terminal communicating with a base station to perform direct communication with a second terminal is provided. The first terminal determines first timing for transmitting or receiving a first signal to or from the base station. Next, the first terminal determines second timing for transmitting a second signal for terminal discovery to the second terminal. When the first timing and the second timing overlap, the first terminal then changes either the first timing or the second timing.

Abstract: A communication method of a terminal and a communication method of a base station for a direct communication link between terminals are disclosed. A base station schedules a reference terminal to transmit a ranging code, and schedules target terminals to receive the ranging code. The reference terminal measures the ranging code received from the target terminals, and transmits a ranging code measurement result to the base station. The base station selects a terminal from among the target terminals to form the direct communication link with the reference terminal among the target terminals based on the ranging code measurement result.
