Abstract

quando a formação de feixe (por exemplo, através de um sistema de onda milimétrica (mmw)) é usada para comunicação sem fio, uma estação-base pode transmitir feixes que são direcionados a determinadas direções. devido à natureza direcional dos feixes no sistema mmw, uma abordagem para determinar uma direção de feixe que forneça um ganho desejável é estudada. o aparelho pode ser um equipamento de usuário (ue). o aparelho recebe, a partir de uma estação-base, uma pluralidade de sinais através de uma pluralidade de feixes da estação-base, sendo que cada um dentre a pluralidade de feixes corresponde a uma respectiva porta de antena de uma pluralidade de portas de antena da estação-base. o aparelho realiza estimação de canal para cada feixe da pluralidade de feixes a partir da pluralidade de portas de antena com base na pluralidade de sinais. o aparelho transmite, para a estação-base, um sinal de retroalimentação que inclui informações sobre um ou mais feixes selecionados a partir da pluralidade de feixes, sendo que o sinal de retroalimentação inclui adicionalmente um ou mais pré-codificadores de enlace ascendente candidatos.
