Abstract

GERAÇÃO DE LIVRO DE CÓDIGOS DE SELEÇÃO DE PORTA TIPO II. Aparelhos, métodos e sistemas são divulgados para geração do livro de códigos de seleção de porta Tipo II. Um aparelho (600) inclui um processador (605) e um transceptor (625) que recebe (805) um conjunto de sinais de referência. O processador (605) identifica (810) um conjunto de portas com base no conjunto de sinais de referência. O processador (605) seleciona (815) um subconjunto de portas do conjunto identificado de portas e gera (820), com base no conjunto de sinais de referência, um indicador de coeficiente de amplitude e pelo menos um indicador de coeficiente de fase para cada porta selecionada. O processador (605) gera (825) um relatório CSI, onde o relatório CSI consiste em um livro de códigos de seleção de porta Tipo II correspondente aos coeficientes gerados e às portas selecionadas.
