Abstract: A discovery signal transmission/reception method and an apparatus for improving energy efficiency of the system are provided. The discovery signal transmission method of a base station in a mobile communication system according to the present disclosure includes acquiring a discovery signal configuration of a neighbor cell, transmitting the discovery signal configuration to a terminal, receiving a measurement report including a result of measurement on a discovery signal of the neighbor from the terminal, the measurement being performed based on the discovery signal configuration, and determining whether to make a handover decision for the terminal based on the measurement report. The discovery signal transmission/reception method of the present disclosure is advantageous in improving energy efficiency of a mobile communication system.

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.
