Abstract: The present invention relates to a procedure for transceiving a sounding reference signal and to a method for operating sounding in a wireless communication system in which an uplink control channel resource dynamically changes. More particularly, the method for transmitting a sounding reference signal by a terminal in a wireless communication system according to the present invention comprises the steps of: receiving uplink/downlink configuration information transmitted from a base station; checking whether a conflict occurs between a physical uplink control channel (PUCCH) resource region based on the uplink/downlink configuration information and a sounding reference signal (SRS); and skipping the transmission of the SRS upon the occurrence of a conflict. The present invention has the advantage of efficiently solving the problem of conflicts between the SRS and the uplink control channel resource without increasing the power consumption burden in the terminal or without excessive restrictions on an SRS transmission subframe or sounding band.

Abstract: Methods and apparatuses are provided in which at least one parameter associated with a sidelink transmission is received from a base station. It is identified whether an uplink transmission is scheduled in a transmission time interval (TTI) in which a sidelink transmission to a second terminal is scheduled. The sidelink transmission is transmitted to the second terminal in the TTI in case that no uplink transmission is scheduled in the TTI. The sidelink transmission is transmitted based on a smaller transmission power value from two transmission power values.

Abstract: Disclosed is a method of transmitting/receiving a signal by a transmission device in a mobile communication system. The method includes: receiving information related to synchronization signals from a Base Station (BS); transmitting a first synchronization signal based on the received information; and receiving a second synchronization signal corresponding to the first synchronization signal based on the received information. When a UE cannot receive a synchronization signal from the BS or is located beyond a coverage of the BS, or when the BS cannot operate due to an emergency or disaster situation, UEs can configure self synchronization therebetween in a predetermined area without any assistance from the BS and thus broadcast and unicast transmission are possible between the UEs based on the synchronization.
