Abstract

Un método y un aparato para realizar transmision conexion-arriba en un sistema de multiple-entrada- de -data multiple- salida - de - data (MIMO) de un solo portador de division de frecuencia de acceso multiple (SC-FDMA) son presentados. En una unidad de recepcion/transmision inalámbrica (WTRU), la data de entrada es codificada y analizada en una pluralidad de corrientes de data. Luego de la modulacion y la transformacion Fourier, es realizada selectivamente una de: transmision de formacion de haces, codificacion tiempo espacio (STC) y multiplexion espacial con base en informacion de estado de canal. Símbolos son entonces mapeados a sub-portadores y transmitidos vía antenas. El STC puede ser codificacion de bloque frecuencia espacio (SFBC) o codificacion de bloque espacio tiempo (STBC). Control de rata por antena puede ser realizado sobre cada corriente de data con base en la informacion de estado de canal. En un Nodo - B, decodificacion MIMO puede realizarse con base en uno de: decodificacion de cuadrado de error mínimo medio (MMSE), decodificacion MMSE de cancelacion de interferencia sucesiva (SIC) y decodificacion de máxima probabilidad (ML). Decodificacion tiempo espacio puede realizarse si ITC es realizado en la WTRU.
