Abstract
Una unidad inalámbrica de transmision/recepcion (WTRU) que comprende: un receptor que tiene un sub-ensamble de acceso multiple por division de frecuencia ortogonal (OFDMA) de dispersion y un sub-ensamble de OFDMA sin dispersion y un sub-ensamble comun, el receptor configurado para recibir símbolos de OFDMA híbridos, en donde los símbolos de OFDMA híbridos incluyen primeros datos dispersados en un primer grupo de sub-portadoras y segundos datos sin dispersion en un segundo grupo de sub-portadoras; el sub-ensamble comun configurado para procesar los símbolos de OFDMA híbridos recibidos y recuperar primeros datos dispersados desmapeados a partir del primer grupo de sub-portadoras y segundos datos sin dispersion desmapeados a partir del segundo grupo de sub-portadoras; el sub-ensamble de OFDMA de dispersion configurado para dispersar inversamente los primeros datos dispersados desmapeados y recuperar primeros datos de usuario unico; y el sub-ensamble de OFDMA sin dispersion configurado para recuperar segundos datos a partir de los segundos datos sin dispersion desmapeados. También se divulga un método para comunicaciones de acceso multiple por division de frecuencia ortogonal (OFDMA) híbrido empleado por la WTRU.
