Title
(PT) sistema e método para gerenciamento de feixe
Abstract
(PT)
um primeiro aparelho pode se comunicar com um equipamento de usuário (ue) através de um feixe ativo. o primeiro aparelho pode transmitir, para o ue, informação indicando uma periodicidade na qual informação de controle está para ser comunicada em um canal de controle através de um feixe de informação de controle. o primeiro aparelho pode comunicar, com o ue, a informação de controle no canal de controle através do feixe de informação de controle na periodicidade. além disso, o primeiro aparelho pode receber uma solicitação para modificar o feixe ativo, o que pode indicar um índice de feixe correspondente a um segundo feixe, e o primeiro aparelho pode modificar o feixe ativo para o segundo feixe correspondendo ao índice de feixe indicado pela solicitação.
