Abstract

Patente de Invenção: <B>"APARELHO DE TERMINAL DE COMUNICAçãO, APARELHO DE COMUNICAçãO DE ESTAçãO DE BASE E MéTODO DE COMUNICAçãO POR RáDIO"<D>. A presente invenção realiza a transmissão/recepção de canais de difusão usando apenas a última fenda de ligação inferior de subquadros usando sinais que têm uma estrutura de TDMA de acordo com um referido de CDMA/TDD, e, assim, manipula de forma flexível vários serviços e evita problemas de interferência em serviços auto-operados em particular. O aparelho de comunicação de estação de base repetidamente transmite uma informação contida em canais de difusão pelo número de vezes correspondentes ao número de compartilhamento de tempo e apropriadamente aloca as fendas de ligação superior e de ligação inferior, desse modo executando a maioria dos aspectos de controle de potência de transmissão de laço aberto de ligação superior e de diversidade de transmissão de estação de base.
