Abstract

A method of controlling transmission power of a terminal performing device-to-device (D2D) communication in a wireless communication system, the method comprising: receiving power control information corresponding to radio resources used by the terminal for D2D communication data from a base station, determining The first transmission power of the radio resource to be used by the terminal for D2D communication among the radio resources, and transmitting data for D2D communication with the determined first transmission power by using the radio resource to be used by the terminal for D2D communication . The present disclosure relates to a communication method and system for converging a 5th generation (5G) communication system for supporting higher data rates beyond a 4th generation (4G) system and a technology for the Internet of Things (IoT). The present disclosure can be applied to smart services based on 5G communication technology and IoT-related technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and security services.

Description

technical field [0001] The present disclosure relates to a communication method of a device-to-device (D2D) communication terminal. More particularly, the present disclosure relates to a method and apparatus for controlling transmission power of a D2D communication terminal, and a method and apparatus for maintaining or controlling a communication range or coverage area of ​​a D2D communication terminal. Furthermore, the present disclosure relates to a D2D power control technique for solving the problem of in-band emission (IBE), inter-carrier interference (ICI), or inter-symbol interference (ISI) caused by D2D terminals in a cellular system. Background technique [0002] In order to meet the demand for wireless data traffic that has increased since the deployment of 4th generation (4G) communication systems, efforts have been made to develop and improve 5th generation (5G) or pre-5G communication systems. Therefore, 5G or pre-5G communication system is also called "super 4...
