Abstract

MÉTODO E SISTEMA PARA MELHORAR A TRANSMISSÃO E A RECEPÇÃO DE DESCRITORES DE CANAL A invenção relaciona-se a um método (200) e sistema para melhorar a transmissão ou a recepção de descritores de canal. O método pode incluir as etapas de - em um sistema de comunicação sem fio (100) que irradia periodicamente descritores de canal regulares (310) a um intervalo fixado (312) - mudar (212) um esquema de modulação e transmitir (216) um ou mais descritores de canal suplementares (314) durante o intervalo fixado entre descritores de canal regulares. O método também pode incluir a etapa de transmitir (214) periodicamente uma contagem de descritor de canal (412) que fornece uma indicação do esquema de modulação mudado.
