Abstract

Un método y una disposición (800) en un equipo de usuario (420) para reportar Información de Estado de Canal, CSI, y un método y una disposición (1000) en una estación base (410) para obtener CSI se proporciona. El equipo de usuario (420) se encuentra en conexión con la estación base (410) en una red de comunicación celular (400). Después de recibir (702) una concesión en una subtrama n que se utiliza para información de CSI, de la estación base, el equipo de usuario determina (703) el tipo de subtrama de la sub-bastidor n+p. El equipo de usuario entonces, informa (704) a la estación base, CSI que refleja condiciones de canal en el tipo de subtrama de subtrama n+p, p es un valor variable.
