Abstract: The present invention relates to a method and an apparatus for transmitting a channel measurement reference signal in a wireless communications system. In particular, while a terminal transmits a non-periodic channel measurement reference signal, the present invention is configured to transmit the non-periodic channel measurement reference signal to one uplink band using a plurality of carriers or clusters, wherein first carriers or clusters are used to transmit a data channel of the terminal and second carriers or clusters are used to transmit the channel measurement reference signal. The signals are processed with FDM and transmitted to each other. In addition, a base station may dynamically set channel measurement bandwidth and resource for transmitting the channel measurement reference signal of the terminal. Moreover, the second carriers or clusters can selectively conduct either data transmission or channel measurement reference signal transmission depending on scheduling information of the base station. According to the present invention, the apparatus does not decrease the capacity of a conventional channel measurement reference signal without affecting interference to other terminals.

Abstract: An embodiment of the present invention provides a method for performing device-to-device (D2D) communication by a terminal in a wireless communication system. The method includes: determining whether a signal including synchronization information is received via at least one of an uplink and a downlink; and transmitting a synchronization information-containing signal when the signal including the synchronization information is not received. According to the embodiment, when a common time reference cannot be acquired from a cellular network, D2D terminals spontaneously acquire the common time reference through a D2D synchronization signal so that effective D2D communication is possible. In addition, since a priority can be allocated in relation to the spontaneous provision of the common time reference of the D2D terminals, each of numerous D2D terminals provides the common time reference, thereby preventing chaos. In addition, the D2D terminal providing the common time reference spontaneously recognizes a cellular network performing a normal operation, and can acquire a common time reference from the relevant cellular network after the provision of the common time reference has been finished.
