Abstract

La présente invention concerne des procédés et un appareil associés aux communications relais sans fil. Une architecture représentative pour des communications relais peut comporter une station de base et une pluralité d'unités d'émission/réception sans fil auxiliaires (H-WTRU) et d'unités d'émission/réception sans fil terminales (T-WTRU). Une communication entre la station de base et une unité T-WTRU peut s'effectuer via une liaison croisée (XL) entre une unité H-WTRU et l'unité T-WTRU. Une communication sur la liaison XL peut être réalisée au moyen d'une pluralité de techniques de codage et de formation de faisceau différentes. En outre, un rapport de mesure peut être configuré sur la liaison XL, et la station de base peut effectuer un contrôle de puissance sur la liaison XL.
