Abstract

Se proporciona un método y aparato para transmitir y recibir información de control en un sistema SC-FDMA. Se generan diferentes códigos ortogonales para diferentes ranuras cada uno incluyendo una pluralidad de símbolos SC-FDMA en una sub-estructura. Una señal de control se genera multiplicando los símbolos de control que llevan la información de control por una secuencia asignada para CDM de la información de control. La señal de canal de control se multiplica por los chips de los códigos ortogonales sobre bases de símbolo SC-FDMA y se transmiten en los símbolos SC-FDMA.
