Abstract

APARELHO TERMINAL DE COMUNICAÇÃO SEM FIO, APARELHO DE ESTAÇÃO BASE DE COMUNICAÇÃO SEM FIO E MÉTODO DE CONFIGURAÇÃO DE CONSTELAÇÃO DE AGLOMERADOS. A presente invenção refere-se a um aparelho terminal de comunicação sem fio em que mesmo quando um sinal SC-FDMA for dividido em uma pluralidade de aglomerados e a pluralidade de aglomerados é então mapeada em respectivas bandas de frequência descontínua (quando C-SC-FDMA é utilizado), o efeito de melhoria de rendimento de sistema pode mantida, enquanto a rendimento de usuário pode ser aprimorado. No aparelho, uma Unidade DFT (210) expõe uma sequência simbólica de domínio de tempo a um Processo DFT, gerando com isso sinais de domínio de frequência. Uma unidade de configuração (211) divide a entrada de sinais da Unidade de DFT (210) em uma pluralidade de aglomerados de acordo com um padrão de aglomerado que está de acordo com um conjunto MCS, um tamanho de codificação, ou o número de Ordenações que ocorrem durante transmissões MIMO, que é indicado em tal entrada de sinais, e então mapeia a pluralidade de aglomerados às suas respectivas de uma pluralidade de recursos de frequência descontínua, com isso definindo uma constelação da pluralidade de aglomerados do domínio de frequência.
