Abstract

Selon ses modes de réalisation, la présente invention se rapporte à un procédé permettant de mesurer la qualité de canal, à un équipement utilisateur et à une station de base. Au cours du procédé de mesure, un équipement utilisateur mesure les signaux et les bruits provenant d'un autre équipement utilisateur sur une ressource prédéfinie, et remet un résultat de mesure à une station de base. Les modes de réalisation de cette invention peuvent répondre aux besoins de différents scénarios.
