Abstract

MÉTODO PARA TRANSMISSÃO DE ENLACE DE SUBIDA MULTI-ANTENA. Um método e aparelho para a transmissão de informações com base em uma relação entre um primeiro canal e um segundo canal é divulgado. método pode incluir a tomada de uma primeira medição de canal correspondendo a uma primeira antena de um terminal sem fio e a tomada de uma segunda medi¢do de canal correspondendo a uma segunda antena do terminal sem fio. O método pode incluir a determinação de uma relação entre o primeiro canal e o segundo canal com base na primeira medição de canal e com base na segunda medi¢ao de canal. O método pode incluir transmissão de informações relacionadas com a transmissão de enlace de subida onde a informação pode ser baseada na relação.
