Abstract

"ESTRUTURA DE BUFFER DE DADOS PARA CANAIS FìSICO E DE TRANSPORTE EM UM SISTEMA CDMA". Uma estrutura de buffer para armazenar símbolos recebidos por meio de numerosos canais (por exemplo, físicos ou de transporte). Cada canal é associado com um intervalo de tempo específico (por exemplo, um período de frame de rádio ou um intervalo de tempo de transmissão (TTI), através do qual os símbolos recebidos são processados (por exemplo, intercalados). A estrutura de buffer inclui um buffer e um gerador de endereços. O buffer é dividido em numerosas seções. Uma seção é atribuída a cada canal que é processado. Cada seção pode ser operada como um buffer circular. O gerador de endereços fornece endereços para gravação de símbolos nas seções atribuídas. Se a estrutura de buffer é usada para os canais de transporte, as seções podem ser atribuídas aos canais de transporte com base nos TTIs associados (por exemplo, em ordem descendente dos TTIs). Para cada canal de transporte compósito codificado (CCTrCH), os canais de transporte no CCTrCH podem ser atribuídos a seções definidas começando-se de um respectivo local inicial (por exemplo, o topo ou a base do buffer) e continuando-se ao longo de uma respectiva direção do buffer (por exemplo, para baixo ou para cima).
