APPARATUS AND METHODS FOR CELLULAR COMMUNICATIONS OVER UNUSED UNLICENCED SPECTRUM

摘要

Apparatus and methods of wireless communications are described for determining one or more bands (e.g. guard bands in wireless local area networks (WLANs)) in unused portions of an unlicensed spectrum positioning one or more carriers for cellular communication (e.g. long term evolution (LTE) or LTE advanced communication) in the one or more bands and performing the cellular communication over the unlicensed spectrum using the one or more carriers. In some non limiting example aspects the cellular communication may be in a standalone mode and the one or more carriers may include a primary component carrier (PCC) that is positioned in a Wi Fi guard band. In these non limiting example aspects the apparatus and methods may further include allocating one or more secondary component carriers (SCCs) in Wi Fi guard bands or in Wi Fi channels where the one or more SCCs are opportunistically tuned or turned ON/OFF based on cell loading or backhaul constraints.
