Abstract  Abstract

The invention claims a system and a method for opportunistic cross radio access technology (RAT) and distributed bandwidth. The system comprises: a wireless wide area network (WWAN) which is configured as the main cell (PCell) in the frequency band and double-mode mobile wireless communication device and a wireless local area network (WLAN) radio and a WWAN radio integrated and configured to act as a secondary cell (SCell). PCell is the unauthorized frequency band to provide additional wireless connectivity to the double-mode mobile wireless device. The PCell controls double-mode mobile wireless device provides network access and mobility and wherein further the unauthorized SCell of downlink and uplink frequency bands to support opportunistic for cross-carrier bandwidth allocation by cross RAT association module.

Systems and methods for opportunistic cross radio access technology (RAT) bandwidth allocation are disclosed. The system comprises wireless wide area network (WWAN) radio configured to be used as a primary cell (PCell) to communicate with a dual mode mobile wireless device on a licensed band and a wireless local area network (WLAN) radio integrated with the WWAN radio and configured to be used as a secondary cell (SCell) to provide additional wireless connectivity to the dual mode mobile wireless device in an unlicensed band that is controlled by the PCell. The PCell provides network access and mobility control for the dual mode mobile wireless device and also supports an opportunistic cross carrier bandwidth allocation through a cross RAT coordination module in the downlink and uplink of the SCell in the unlicensed band.
