Abstract

são descritos método, sistemas e aparelhos para comunicação sem fio em um aparelho. um aparelho pode distinguir um preâmbulo enviado de um aparelho configurado para uma primeira rat (como, por exemplo, wlan, wifi, etc.) de um preâmbulo enviado de um aparelho configurado para uma segunda rat (como, por exemplo, lte, lte-a, lte-u, etc.). um aparelho sem fio associado a uma segunda rat pode transmitir um preâmbulo de utilização dupla através de um canal de frequência baseado em disputa. o preâmbulo de utilização dupla pode funcionar como um preâmbulo válido para uma primeira rat e pode ser recebido e decodificado por aparelhos associados à primeira rat além de aparelhos associados à segunda rat. o preâmbulo de utilização dupla pode incluir também uma assinatura associada à segunda rat. a assinatura pode ser embutida com o preâmbulo de modo que reduza ao mínimo a interferência com o preâmbulo válido e seja detectada por aparelhos associados à segunda rat.
