Abstract

MÉTODOS PARA SINALIZAÇÃO DE CONTROLE PARA SISTEMAS SEM FIO. Para prover efetivamente e eficientemente as informações de controle, um canal aponta-dor de transmissão (BPCH) pode ser utilizado para identificar o tipo e talvez a localização relativa de informações de controle que estão sendo providas em uma dada estrutura de quadro, tal como um subquadro, um quadro, ou um superquadro. Um subquadro (ou uma entidade de quadro similar, tal como um quadro ou um superquadro) pode ter um BPCH e um segmento de informações de controle de sistema correspondente no qual as informações de controle podem residir. O segmento de informações de controle de sistema pode ter qualquer número de blocos de informações de controle, em que cada bloco de informações de controle que está presente pode corresponder a um tipo específico de informações de controle. O BPCH é utilizado para identificar o tipo de informações de controle que estão presentes em um segmento de informações de controle de sistema correspondente, e se necessário ou desejado, as localizações relativas das várias informações de controle.
