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.A method and an apparatus for performing top-up transmission in a multi-input-multiple-data-output-of-data (MIMO) system of a single carrier of multiple access frequency division (SC-FDMA) are presented . In a wireless reception / transmission unit (WTRU), the input data is encoded and analyzed in a plurality of data streams. After modulation and Fourier transformation, one of: beam formation transmission, space time coding (STC) and spatial multiplexing based on channel status information is selectively performed. Symbols are then mapped to subcarriers and transmitted via antennas. The STC can be space frequency block coding (SFBC) or space time block coding (STBC). Rat control by antenna can be performed on each data stream based on the channel status information. In a Node-B, MIMO decoding can be performed based on one of: minimum minimum error square decoding (MMSE), MMSE decoding of successive interference cancellation (SIC) and maximum probability decoding (ML). Time space decoding can be done if ITC is performed in the WTRU.
