Abstract

são determinados os pesos de antena de uma pluralidade de direções de feixe formado (251, 252). a transmissão na primeira direção de feixe formado (251) é priorizada sobre a transmissão na segunda direção de feixe formado (252), por exemplo, durante a varredura de feixe. tais técnicas podem encontrar aplicação na descoberta de um nó de acesso 122 por um dispositivo (130) anexado em uma rede sem fio.
