Abstract

projeto de livro de código e estrutura para retorno multi-granular. uma primeira matriz de pré-codificação w1 é selecionada a aprtir de uma primeiro livro de códigos compreendido conjuntos de matrizes de pré-codificação específicas de classificação. o primeiro livro de códigos é caracterizado por existirem menos matrizes de pré-codificação associadas com classificações mais elevadas do que assiciadas com classificações inferiores, e caracterizado por matrizes de pré-codificação associadas com classificxação acima de um certo nível sendo todas as matrizes diagonais. a primeira matriz de pré-codificação selecionada w1 é usada para selecionar uma segunda matriz de pré-codificação w2 de um segundo livro de código, de modo que a primeira e a segunda matrizes de pré-codificação selecionadas formam um conjunto precodificador específico de uma classificação desejada. o segundo livro de códigos é caracterizado por matrizes de pré-codificação de tamanhos diferentes associadas com cada uma das n classificações totais, em que n é um número inteiro maior do que um. a informação sobre o conjunto precodificador é relatada para um nó de rede sobre um canal de transmissão de uplink.
