Abstract: The present disclosure relates to a communication technique for converging IoT technology and a 5G communication system for supporting higher data transmission rate after a 4G system, and a system thereof. The present disclosure can be applied to an intelligent service (for example, a smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, and security and safety related service etc.) based on 5G communication technology and IoT related technology. The present invention relates to a signal receiving method and apparatus of a terminal in device-to-device wireless communication. In the present invention, a D2D reception terminal can measure a DM RS transmitted together with a PSBCH or detect energy with respect to the entirety of or a part of a symbol region through which the PSBCH or DM RS in a synchronization subframe can be transmitted so as to enable use as a criterion for determining whether to retry PSBCH decoding. When a DM RS measurement level or an energy detecting level is larger than a certain threshold value, the D2D reception terminal recognizes that the PSBCH has been transmitted and may retry the PSBCH decoding for a certain time or a certain number of times. When a DM RS measurement level or an energy detecting level is smaller than a certain threshold value, the D2D reception terminal recognizes that the PSBCH has not been transmitted and may not retry the PSBCH decoding. When the PSBCH decoding is not retried, the D2D reception terminal can try other PSSS/SSSS detection. Through the present invention, the D2D reception terminal can avoid inefficient operation of retrying the PSBCH decoding for a certain time or a certain number of times despite non-transmission of the PSBCH.

Abstract: Methods and apparatuses are provided for Device-to-Device (D2D) communication in a wireless communication system. A terminal receives a D2D communication initiation message from a base station. The terminal measures strength of a received signal on a radio resource predetermined for use in the D2D communication. The terminal transmits a measurement report of the strength of the received signal to the base station. The terminal receives allocation of a resource in the radio resource for transmitting a discovery signal to another terminal for the D2D communication from the base station.

Abstract: Methods and apparatuses for controlling power in a communication system are provided. A first user equipment (UE) receives power control related information from a base station. Data is transmitted to a second UE based on a transmission power, if there is no uplink transmission. The transmission power is based on a first transmission power determined by a number of assigned resource blocks, a path loss, and the received power control related information.

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.
