Abstract

MÉTODO DE REALIMENTAÇÃO DE MU-CQI EM UM SISTEMA DE COMUNICAÇÃO, DISPOSITIVO DE PONTO DE TRANSMISSÃO E EQUIPAMENTO DE USUÁRIO. A presente invenção refere-se a um método, a um equipamento de usuário e a um dispositivo de ponto de transmissão para realimentação de indicador de qualidade de canal (MU-CQI) para o ponto de transmissão em um sistema de comunicação incluindo o ponto de transmissão e uma pluralidade de equipamentos de usuário, o método compreendendo as etapas: o ponto de transmissão envia uma mensagem para um equipamento de usuário de destino da pluralidade de equipamentos de usuário, e o equipamento de usuário de destino calcula o MU-CQI baseado na mensagem, e realimenta o MU-CQI para o ponto de transmissão. A presente divulgação permite a operação MU dinâmica, e melhora o desempenho de adaptação de ligação com sobrecarga de ligação descendente marginal. E a precisão não é limitada pelo tamanho da tabela de codificação.
