Abstract

"MéTODO DE CONTROLE DE FEIXE DE TRANSMISSãO, DISPOSITIVO TRANSCEPTOR DE ANTENA ADAPTATIVA, E ESTAçãO RáDIO BASE". Mudanças nas instruções de aumento/diminuição de potência de transmissão decodificadas a partir de bits TPC são monitoradas, e quando as instruções de aumento/ diminuição em um intervalo de tempo prescrito são instruções que tendem aumentar potência de transmissão, a direção de pico ou a largura de lóbulo principal do feixe de transmissão é alterada regulando a potência de transmissão ou pesos de antena de transmissão que correspondem a cada dispositivo de uma pluralidade de dispositivos de antena. Estes processos são repetidos até eliminar instruções que tendem aumentar potência de transmissão nas instruções de aumento/diminuição de potência de transmissão ou até que o número de mudanças do feixe de transmissão alcance um valor máximo fixado de antemão.
