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: The present invention relates to a communication technology and system converging the 5G communication system for supporting a data rate higher than that of the 4G system with IoT technology. The present invention is applicable to intelligent services based on 5G communication and IoT technologies (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security, and safety services. In detail, the discovery signal transmission method of a terminal in a wireless communication system supporting Device to Device (D2D) communication includes receiving discovery resource pool information from a base station, selecting a resource for transmitting discovery signal based on the discovery resource pool information, determining whether the selected resource is overlapped with a resource configured for transmitting a D2D synchronization signal, and determining whether to transmit the discovery signal based on the determination result.

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.
