Abstract

APARELHO E MÉTODOS PARA COMUNICAÇÃO CELULAR ATRAVÉS DE ESPECTRO NÃO LICENCIADO NÃO USADO. Aparelho e métodos de comunicação sem fio são descritos para determinar uma ou mais bandas (por exemplo, bandas de proteção em redes de área local sem fio (WLANs)) em porções não usadas de um espectro não licenciado, posicionar uma ou mais portadoras para comunicação celular (por exemplo, comunicação de evolução de longo prazo (LTE) ou LTE avançado) em uma ou mais bandas, e executar a comunicação celular através do espectro não licenciado usando uma ou mais portadoras. Em alguns aspectos de exemplo não limitadores, a comunicação celular pode estar em um modo independente e uma ou mais portadoras podem incluir uma portadora de componente principal (PCC) que é posicionada em uma banda de proteção de Wi-Fi. Nesses aspectos de exemplo não limitadores, o aparelho e métodos podem incluir ainda alocar uma ou mais portadoras de componente secundário (SCCs) em bandas de proteção de Wi-Fi ou em canais de Wi-Fi, onde uma ou mais SCCs são sintonizadas de modo oportunista ou LIGADAS/DESLIGADAS com base em limitações de backhaul ou carga de célula.
