Abstract

La présente invention concerne la planification de liaison montante pour un terminal. Pour ce faire, une station de base reçoit des informations concernant une interférence de liaison montante due au terminal provenant de stations de base voisines, transmet les informations concernant l'interférence de liaison montante au terminal, reçoit des informations concernant la puissance d'émission d'un circuit de retour provenant du terminal par l'intermédiaire du circuit de retour, compare la puissance d'émission du circuit de retour et la puissance de réception du circuit de retour afin d'estimer la perte d'émission et réalise une planification de liaison montante pour le terminal en répercutant la perte d'émission.
