Abstract

"CONTROLE DE POTêNCIA DO LINK DE EMISSãO DE MúLTIPLOS FLUXOS DE DADOS TRANSMITIDOS PARA UMA ESTAçãO MóVEL USANDO UM CANAL DE CONTROLE DE POTêNCIA EM COMUM". Um método e um equipamento para controlar os níveis de potência de transmissão de uma pluralidade de fluxos de dados diferentes (120, 120a, 122, 122a, 124, 124a) transmitidos a partir de pelo menos uma estação base para uma estação móvel em um sistema móvel de rádio comunicação. os primeiro e segundo fluxos de dados são transmitidos a partir da estação base e recebidos na estação móvel. Um fluxo de comandos de controle de potência é formado na estação móvel de acordo com o primeiro ou o segundo fluxo de dados recebido. Um sinal de controle de potência é formado na estação móvel a partir do primeiro fluxo de comandos de controle de potência e transmitido para a estação base. Um fluxo recebido de comandos de controle de potência é formado a partir do sinal de controle de potência recebido na estação base e os níveis de potência de transmissão dos primeiro e segundo fluxos de dados provenientes da estação base são controlados de acordo com o fluxo recebido de comandos de controle de potência.
