Title
(PT) sistema e método para gerenciamento de feixe
Abstract
(PT)
um primeiro aparelho pode transmitir, a um equipamento de usuário (ue), em um canal de controle, uma ou mais indicações de um ou mais índices de feixe correspondendo a um ou mais feixes. o primeiro aparelho pode transmitir, ao ue, um ou mais sinais de referência através dos um ou mais feixes correspondendo aos um ou mais índices de feixe. os siais de referência podem ser usados pelo ue para selecionar uma melhor submatriz e/ou receber combinador para comunicação com o primeiro aparelho.
