Abstract

"TRANSMISSãO DE INFORMAçãO SOBRE FORMATO DE TRANSMISSãO EM CANAIS DEDICADOS". Transmissões no canal dedicado são codificadas utilizando-se um conjunto de parâmetros que são extraídos de uma grande seleção de parâmetros potenciais. Se a estação remota não conhecer o conjunto específico de parâmetros que foram utilizados por uma estação base, então a estação remota terá que tentar decodificar a transmissão utilizando cada conjunto de parâmetros até que a transmissão seja decodificada corretamente. Esta é uma metodologia ineficaz. Conseq³entemente, as informações sobre formato de transmissão são tipicamente transmitidas em um canal de broadcast, de modo que uma estação remota possa receber as informações sobre o formato de transmissão. Entretanto, o canal de broadcast tem problemas de segurança. Descrevem-se novos métodos e equipamento para permitir que uma estação base determine um conjunto de seq³ências de códigos de Walsh que possa ser utilizado para enviar as informações sobre o formato de transmissão no canal dedicado, e não em um canal de broadcast (620). A utilização do conjunto superposto permite que a estação remota decodifique as informações.
