Abstract
(EN) A signal transmission and reception method by a terminal of a mobile communication system according to an embodiment of the present specification comprises the steps of: receiving configuration information related to a discovery signal from a base station; determining a discovery signal transmission resource on the basis of the configuration information; and transmitting the discovery signal using transmission power determined on the basis of a position of the determined discovery signal transmission resource and the configuration information. According to an embodiment of the present specification, an interference effect can be reduced when a signal is transmitted by a terminal in a mobile communication system and communication performance can be improved.
(FR) Un procédé de transmission et de réception de signal par un terminal d'un système de communications mobiles selon un mode de réalisation de la présente invention comprend les étapes consistant à : recevoir des informations de configuration relatives à un signal de recherche, d'une station de base ; déterminer une ressource de transmission de signal de recherche d'après les informations de configuration ; et transmettre le signal de recherche au moyen de la puissance de transmission déterminée d'après une position de la ressource de transmission de signal de recherche déterminée et les informations de configuration. Selon un mode de réalisation de la présente invention, un effet de brouillage peut être réduit quand un signal est transmis par un terminal dans un système de communications mobiles et une performance de communication peut être améliorée.
