Abstract

"MéTODO E DISPOSITIVO PARA CONTROLAR ENERGIA DE TRANSMISSãO DE UMA ESTAçãO BASE", em um sistema de comunicação móvel CDMA. A energia de transmissão total <B> Ptotal <D> dos canais de comunicação é calculada e comparada com a energia de transmissão total máxima <B> Pmax <D>. Uma taxa de redução de energia de transmissão <B> Dt-1 <D> armazenada no momento do processo de controle anterior é usada ao calcular a energia de transmissão máxima total <B> Pmax <D>. A proporção de insuficiência de energia de transmissão é calculada como taxa de redução de energia <B> Dt <D> com base nos resultados de comparação, e esta taxa de redução <B> Dt <D> é usada para reduzir a energia de transmissão de cada canal de comunicação.
