Abstract: Disclosed herein are systems and methods for carrier aggregation and fast network-switching with a single-baseband modem, carrier-aggregation-capable wireless-communication device (WCD). One embodiment takes the form of a system that includes a first RF integrated circuit (RFIC), a second RFIC, a baseband processor coupled to the first and second RFICs, a first carrier-aggregation circuit, a fast-network-switching connection manager coupled to the baseband processor, and a mode controller coupled to the baseband processor and to the fast-network-switching connection manager. The mode controller is configured to selectively place the wireless-communication device in a carrier-aggregation mode or in a fast-network-switching mode. In the carrier-aggregation mode, the WCD is operable to conduct carrier aggregation using at least the first carrier-aggregation circuit. In the fast-network-switching mode, the WCD is operable to conduct fast network switching using the fast-network-switching manager.

Abstract: A broadband device (105) can detect a proximate narrowband transmission (152) from a narrowband communication device (145). The narrowband transmission (152) can be in close enough proximity (155) to at least one bearer channel of the broadband device (105) to result in interference on the narrowband reception (152) when the broadband device (105) is transmitting and the narrowband communication device (145) is concurrently receiving. Responsive to the detecting, the broadband device (105) can gate a broadband transmission (142) to ensure the broadband transmission (142) does not interfere with the proximate narrowband reception (152). In absence of detecting the narrowband transmission (152), the broadband transmission (142) from the broadband device (105) would not be gated.
