Abstract

transmissão de informações em um sistema de comunicação sem fio. métodos, dispositivos e sistemas para a transmissão de informações em um sistema de comunicação sem fios são divulgados. em uma forma de realização, um método de transmissão de um sistema de comunicação sem fios compreende a determinação por um dispositivo sem fios (201) uma configuração de uma pluralidade de amplificadores de potência (207) para conseguir um modo de transmissão de antena única; amplificar um sinal pelo referido dispositivo sem fios (201) usando a configuração da pluralidade de amplificadores de potência (207) para formar uma pluralidade de sinais amplificados; simultaneamente a transmitir ao ou aproximadamente o mesmo tempo pelo dispositivo sem fios (201) para uma estação de base (202) a pluralidade de sinais amplificados a partir de uma pluralidade de antenas físicas (212), em que a pluralidade de antenas físicas (212) são acopladas á configuração da pluralidade de amplificadores de potência (207), e em que a potência medida de transmitir a totalidade da pluralidade de antenas físicas (212) é aproximadamente o mesmo que a portência de transmissão necessária usando o modo de transmissão de antena única.
