Abstract

La presente invención se refiere a métodos y aparatos para realizar transmisión de enlace ascendente en un sistema de comunicación inalámbrica. Una terminal móvil se proporciona con un conjunto de formatos de transporte disponibles al recibir por lo menos una concesión de UL que comprende una indicación de formato de transporte que señala a uno o más formatos de transporte. La terminal móvil entonces selecciona un formato de transporte adecuado del conjunto, por ejemplo, dependiendo de las condiciones de canal de propagación, para transmisión de una transmisión programada.
