Abstract

DISPOSITIVO DE TRANSMISSãO E MéTODO DE TRANSMISSãO. A presente invenção refere-se a um dispositivo de transmissão capaz de impedir aumento de informação de retransmissão ou codificação de bit redundante e de aperfeiçoar um rendimento em um método de comunicação MIMO. Neste dispositivo, uma unidade de codificação (130) sujeita os dados transmitidos a partir de uma primeira antenas de transmissão (110) e de uma segunda antena de transmissão (120), cada uma formada por uma pluralidade de antenas, ao processamento de codificação, todos ao mesmo tempo. As unidades de modulação (113,123) modulam os dados codificados pela unidade de codificação (130) para cada uma dentre a primeira e a segunda antena de transmissão (110,120). As unidades de transmissão (115, 125) processam os dados modulados de modo que eles podem ser transmitidos a partir da primeira e da segunda antenas (110,120) correspondentes. Uma unidade de controle de transmissão (160) executa o controle de transmissão dos dados transmitidos a partir das respectivas antenas (110, 120). Quando retransmitindo dados, a unidade de controle de transmissão (160) retransmite os dados transmitidos a partir de uma antena de transmissão possuindo um menor número de antenas do que a primeira e a segunda antenas (110, 120).
