Abstract

MÉTODO E APARELHO DE CONTROLE DE POTÊNCIA ELÉTRICA DE TRANSMISSÃO É revelado um método e um aparelho capazes de minimizar uma redução na quantidade de potência elétrica de transmissão máxima sem degradar uma razão de potência de escoamento de canal adjacente quando se multiplexa em código a informação de controle adicional de multiplexação de código com dados e informação de controle principal. Um dispositivo móvel checa os valores dos fatores de ganho (Beta)d e (Beta)c quando executa a multiplexação de código para transmitir os sinais a partir dos canais DPDCH para transmitir dados, DPCCH para transmitir informação de controle principal, e HSDPCCH para transmitir informação de controle adicional. Uma potência elétrica de transmissão máxima é reduzida em uma pluralidade de níveis com base no resultado de verificação e na razão (Deltahs) entre os fatores de ganho (Beta)c e (Beta)d. Pode ser preferível verificar a presença ou ausência de dados de transmissão em vez do fator de ganho (Beta)d. Nesse caso, quando nenhum dado de transmissão está disponíveis, a potência elétrica de transmissão máxima é reduzida em uma pluralidade de níveis com base em (Delta)hs. Quando os dados de transmissão estão disponíveis, a potência elétrica de transmissão máxima é reduzida em uma pluralidade de níveis com base no fator de ganho (Beta)c e em (Delta)hs.
