Abstract

APARELHO E MéTODO PARA MUDAR ADAPTATIVAMENTE UM ESQUEMA DE CONTROLE DE ENERGIA DE ENLACE ASCENDENTE DE ACORDO COM A SITUAçãO DO DISPOSITIVO MóVEL EM UM SISTEMA DE COMUNICAçãO MóVEL TDD São fornecidos um aparelho e método para mudar um esquema de controle de energia no enlace ascendente de acordo com a situação do dispositivo móvel em um sistema de comunicação móvel TDD. Uma estação de assinante transmite para uma estação base uma mensagem de solicitação de mudança de controle da energia incluindo informação a respeito de um esquema de controle de energia solicitado. Quando do recebimento da mensagem de solicitação de mudança de controle de energia, a estação base seleciona um esquema de controle de energia para o enlace ascendente da estação do assinante e transmite para a estação do assinante uma mensagem de comando de mudança no controle da energia incluindo informação sobre o esquema de controle de energia selecionado. A estação do assinante extrai, quando do recebimento da mensagem de comando da mudança no controle da energia da estação base, a informação do esquema de controle de energia da mensagem de comando de mudança no controle da energia e seleciona um esquema de controle da energia de acordo com a informação extraída.
