Abstract

trata-se de métodos, sistemas, e dispositivos para capacidade de sistema para comunicações sem fio aumentadas através de modulação hierárquica de camadas de múltiplas transmissões durante certos subquadros de transmissão em um sistema de comunicações sem fio. vários cenários de implantação podem ser suportados, que podem fornecer comunicações moduladas tanto em uma camada de modulação base quanto em uma camada de modulação de aprimoramento que é sobreposta na camada de modulação base. os sinais de referência podem ser fornecidos para estimativa de canal tanto para a camada de modulação base quanto para a camada de modulação de aprimoramento.
