Abstract

programação de comutação de antena. métodos, sistemas e dispositivos para comunicação sem fio são descritos. um equipamento de usuário de múltiplas antenas (ue) pode se comunicar com uma estação base utilizando uma primeira antena, determinar a comutação da primeira antena para uma segunda antena para realizar a comunicação com a estação base, determinar uma janela de silêncio na qual a comunicação com a estação base está suspensa, programar a comutação da primeira antena para a segunda antena para que ocorra durante a janela de silêncio, e comutar da primeira antena para a segunda antena durante a janela de silêncio.
