Abstract

distribuição de indicador de controle de enlace descendente para programação de portadora cruzada. os aspectos se referem a comunicações sem fio que utilizam programação de portadora cruzada. os métodos e o aparelho incluem gerar pelo menos uma partição em um canal de controle a partir de uma célula de programação, sendo que a pelo menos uma partição inclui uma pluralidade de segmentos de canal de controle, tais como segmentos pdcch, que são dispostos nos respectivos tempos dentro da pelo menos uma partição. cada um dos segmentos de canal de controle inclui informações de controle, tais como dcis que correspondem às respectivas partições para uma célula programada. a distribuição das informações de canal de controle nos segmentos ou intervalos ao longo do tempo produz temporização de decodificação aprimorada em um ue na célula programada.
