Abstract

métodos para reduzir interferência em um sistema de comunicação sem fio modalidade de exemplo são direcionadas para métodos de reduzir interferência em um sistema de comunicação sem fio. em pelo menos uma modalidade de exemplo, um método inclui primeira determinação (s360), por meio de um primeiro transmissor tendo uam antena multidirecional configurada para produzir uma pluralidade de feixes, para determinar pelo menos um nível de interferência de pelo menos um feixe interferente de uma pluralidade de feixes de pelo menos um transmissor no sistema de comunicação, segunda determinação (s340) para determinar um padrão de feixe de transmissão com base no nível de interferência, o padrão de feixe de transmissão indicando uma sequência de iluminar a pluralidade de feixes em intervalos de tempo correspondentes, terceira determinação (s345) para determinar um padrão de reutilização de frequência fracionária com base no padrão de feixe de transmissão, e transmissão de dados (s350) com base no padrão de feixe de transmissão e no padrão de reutilização de frequência.
