1. A method of reconfiguring a radio bearer by a user equipment, the method comprising:
receiving a higher layer signal including information for changing a data radio bearer type of one selected radio bearer configured to receive downlink data from a base station using only wireless local area network (WLAN) wireless resources;
performing, by a packet data convergence protocol (PDCP) entity, a PDCP data recovery procedure based on the information for changing the data radio bearer type of the one selected radio bearer; and
performing, by the PDCP entity, a reordering procedure for the one selected radio bearer,
wherein the information for changing the data radio bearer type of the one selected radio bearer includes information for changing the one selected radio bearer from a first radio bearer type receiving the downlink data using only the WLAN wireless resources to a second radio bearer type receiving the downlink data using only wireless resources of the base station and maintaining radio bearer types of the other radio bearers configured to receive downlink data and to transmit uplink data using one of the WLAN wireless resources and the wireless resources of the base station; and
wherein the PDCP data recovery procedure and the reordering procedure are performed by the PDCP entity when the data radio bearer type is changed from the first radio bearer type to the second radio bearer type based on the information for changing the data radio bearer type.
