Claim Text:
1. A method for performing, by a mobile station (MS) supporting two or more radio access technologies, communication with two or more networks, the method comprising: receiving, by the MS while being served in a cellular network and a wireless local area network (WLAN), a signal from the WLAN; and receiving, by the MS from the cellular network, control information including information about a feedback channel; transmitting, by the MS to either the cellular network or the WLAN, feedback information regarding the WLAN through the feedback channel, wherein the cellular network allocates a cellular uplink resource by a non-contention based scheme and the WLAN allocates a WLAN uplink resource by a contention based scheme in which the MS competes with other MSs to obtain the WLAN uplink resource, wherein, if the MS has failed to obtain the WLAN uplink resource from the WLAN within a predetermined time by the contention based scheme, the feedback information is transmitted to the cellular network via the cellular uplink resource allocated by the non-contention based scheme, and wherein the information about the feedback channel includes cellular uplink resource allocated for transmitting the feedback information to the cellular network.
