Abstract
(EN)
The present invention relates to a wireless communication system and, specifically, provides a communication method and an apparatus therefor, in which: transmission power information relating to a first downlink (DL) signal is received from a parent node; the first DL signal is transmitted to a child node on the basis of the transmission power information; a first uplink (UL) signal is transmitted to the parent node on the basis of the transmission power information; the first DL signal and the first UL signal are multiplexed by frequency division multiplexing (FDM) or spatial division multiplexing (SDM); the transmission power information includes a maximum transmission power value of the first DL signal; and a magnitude of a transmission power of one of the first DL signal and the first UL signal is adjusted so that the magnitude of the transmission power of the first DL signal and the magnitude of the transmission power of the first UL signal do not differ by a value equal to or greater than threshold value.

La présente invention concerne un système de communication sans fil et, plus précisément, un procédé de communication et un appareil associé, dans lesquels : des informations de puissance de transmission relatives à un premier signal de liaison descendante (DL) sont reçues en provenance d'un noeud parent ; le premier signal DL est transmis à un noeud enfant sur la base des informations de puissance de transmission ; un premier signal de liaison montante (UL) est transmis au noeud parent sur la base des informations de puissance de transmission ; le premier signal DL et le premier signal UL sont multiplexés par multiplexage par répartition en fréquence (FDM) ou par multiplexage par répartition dans l'espace (SDM) ; les informations de puissance de transmission comprennent une valeur de puissance de transmission maximale du premier signal DL ; et une amplitude d'une puissance de transmission de l'un du premier signal DL et du premier signal UL est réglée de sorte que l'amplitude de la puissance de transmission du premier signal DL et l'amplitude de la puissance de transmission du premier signal UL ne diffèrent pas d'une valeur égale ou supérieure à la valeur seuil.
