Abstract

Se revela un método para la asignacion de un canal de control enlace ascendente a un canal físico en un sistema de acceso multiple por distribucion de frecuencias de una sola portadora (SC-FDMA). Una unidad de transmision y recepcion inalámbrica (WTRU) genera bits de control a ser transferidos por un canal de control. La WTRU asigna el canal de control a una pluralidad de subportadoras entre subportadoras en un bloque de recursos asignado a una WTRU y a al menos un bloque largo (LB) en un subcuadro. El canal de control incluye al menos uno entre un canal de control no asociado a datos y un canal de control asociado a datos. Las subportadoras asignadas al canal de control no asociado a datos se distribuyen sobre todo, o una fraccion de, al menos un bloque de recursos. El canal de control no asociado a los datos puede asignado a las subportadoras con una o más subportadoras como una unidad básica. Las subportadoras asignadas pueden estar consecutivas en el dominio de la frecuencia. Los bits de control pueden ser multiplexados con bits de datos en un LB.
