1. An apparatus of a dual mode base station that includes a wireless wide area network (WWAN) access point that is integrated with a wireless local area network (WLAN) access point, the apparatus comprising circuitry configured to:

  • perform, via the WWAN access point of the dual mode base station, a Third Generation Partnership Project (3GPP) Release 8, 9 or 10 attach procedure with a WWAN radio of a dual mode user equipment (UE);

    perform, via the WWAN access point of the dual mode base station, a WLAN carrier aggregation capability exchange with the WWAN radio of the dual mode UE, wherein the WWAN access point receives a WLAN carrier aggregation capability of the dual mode UE during the WLAN carrier aggregation capability exchange;

    determine, at the dual mode base station, whether to turn on the WLAN access point that is integrated in the dual mode base station based on the WLAN carrier aggregation capability to enable WLAN carrier aggregation, wherein traffic for the dual mode UE is offloaded from the WWAN access point to the WLAN access point when the WLAN access point is turned on at the dual mode base station; and

    obtain information when the WLAN access point is turned on, wherein the information is related to channel interference within a coverage area of the dual mode base station and a number of WLAN deployments.
