Method and apparatus for transmitting and receiving data using WLAN radio resources

Abstract:

Provided is a method and apparatus for processing control plane data to enable an evolve Node B (eNB) and a User Equipment (UE) to transmit and/or receive user plane data through a WLAN carrier when the user plane data is transmitted by adding a WLAN radio resource to an E-UTRAN carrier in a radio access network (RAN) level. Particularly, provided is a method for a UE to transmit and receive data, the method including: receiving, from an eNB, wireless local area network (WLAN) cell configuration information which is for transmitting and receiving data using a WLAN radio resource; performing WLAN association based on the WLAN cell configuration information; transmitting a WLAN access confirmation message to the eNB; and receiving, from the eNB through a higher layer signaling, tunnel configuration information which is for the UE to set up a tunnel with the eNB through the WLAN radio resource.
