Abstract

ALOCAçãO DE RECURSO DE RáDIO EM SISTEMA DE MULTIPLEXAçãO ORTOGONAL POR DIVISãO DE FREQüêNCIA Uma capacidade de enlace reverso ("uplink") é aumentada por um método no qual mais de duas estações móveis utilizam simultaneamente um recurso de rádio alocado para uma estação móvel. Um método de alocação de um recurso de rádio em um sistema de multiplexação por divisão de ortogonal de freqüência compreende receber dados associados com um mapa de alocação de recursos de rádio a partir de uma estação base, onde o mapa de alocação de rádio compreende parâmetros de controle para transmitir dados de enlace reverso para a estação base. Os parâmetros de controle compreendem o indicador de padrão de piloto ortogonal para utilizar padrões de piloto ortogonal associados ao suporte da transmissão dual pelo menos simultânea por pelo menos uma estação base e para uso na mesma faixa de freqüência e na mesma duração de tempo. Os padrões de piloto ortogonal compreendem pelo menos um piloto negativo sendo utilizado para uma unidade de alocação básica de enlace reverso. Em seguida, a estação móvel transmite os dados de enlace reverso para a estação base por utilizar os padrões de piloto ortogonal.
