    Abstract: A method of offloading data is provided by a UE. The UE receives data from a macro cell base station over an MC-RB while an E-RAB between the macro cell base station and a gateway is established. The UE receives a first connection reconfiguration message from the macro cell base station after the E-RAB between a small cell base station and the gateway is established, and establishes an SC-RB according to the first connection reconfiguration message. Next, the UE receives a second connection reconfiguration message from the macro cell base station after a path between the macro cell base station and the gateway is switched to a path between the small cell base station and the gateway, and data for the MC-RB are exhausted on the macro cell base station. Then, the UE releases the MC-RB and switches to the SC-RB.

    Abstract: Provided is a link adaptation transmission and reception method in device-to-device (D2D) communication based on cellular mobile communication. An operation method of a terminal in the link adaptation method according to the present invention includes receiving information related to a first transmission through a D2D link, performing transmission for an opposite terminal using the information related to the first transmission, and determining information related to a second transmission after the transmission based on reception from the opposite terminal. Using the link adaptation method according to the present invention, an adaptive modulation and coding scheme may be provided at the time of data transmission on a D2D link while minimizing control of a base station, thereby reducing the complexity of a cellular network due to the D2D communication.
