Abstract

Patente de Invenção: "MéTODO E EQUIPAMENTO PARA TRANSMITIR SINAIS DE CONTROLE DE POTêNCIA DE LIGAçãO DE RETORNO COM BASE NA PROBABILIDADE DE QUE O COMANDO DE CONTROLE DE POTêNCIA ESTEJA ERRADO". um método e um equipamento para controlar a potência de transmissão de uma pluralidade de rádio unidades móveis (800) transmitindo para uma estação base (900 ) em um sistema de rádio telefonia móvel. Para cada uma das unidades móveis (800) no sistema é medida uma estimativa de força de sinal na estação base (900) com base em sinais de ligação de retorno enviados a partir das unidades móveis (800) e recebidos na estação base (900), em que cada estimativa de força de sinal está associada com uma das unidades móveis (800) . A estimativa de força de sinal associada a cada unidade móvel (800) é comparada a um limite. A seguir, para cada unidade móvel (800) na pluralidade de unidades móveis (800), caso a estimativa de força de sinal associada à unidade móvel (800) for maior que o limite, um bit de controle de potência possuindo um primeiro valor é designado para a unidade móvel (800); ao contrário, caso a estimativa de força de sinal associada à unidade móvel seja menor que o limite, um bit de controle de potência possuindo um segundo valor é designado para a unidade móvel (800). Um ganho variável que é uma função da diferença entre a estimativa de força de sinal associada à unidade móvel (800) e o limite é a seguir aplicado a cada bit de controle de potência. O ganho variável aplicado a cada bit de controle de potência aumenta a medida que aumenta a magnitude da diferença entre a estimativa de força de sinal associada à unidade móvel (800) e o limite. Cada bit de controle de potência ajustado em ganho é a seguir transmitido para as unidades móveis (800).
