Abstract

Se provee un método y aparato para indicar a una unidad de comunicaciones una pluralidad de esquemas de modulacion y codificacion (MCS) a utilizar en la comunicacion. Se determina un primer MCS para los primeros bloques de recursos a enviar a unaprimera unidad remota o estacion de base, y se determina un segundo MCS para un segundo bloque de recursos a enviar a la unidad remota o la estacion de base. Se transmite un mensaje indicando el primero y el segundo MCS e indicando también losprimeros bloques de recursos y el segundo bloque de recursos. Por ultimo, se transmite una primera PDU a la unidad remota o la estacion de base en un primer tiempo usando el primer MSC y los primeros bloques de recursos, y se transmite una segundaPDU a la unidad remota o la estacion de base en el primer tiempo usando el segundo MCS y el segundo bloque de recursos.
