Abstract: A method of transmitting and receiving a control channel in a wireless communication system is provided. A base station allocates a data channel to a radio resource, adds start position information of the data channel into a payload of a control channel, and performs signaling for indication information on the start position information added into the payload of the control channel to a terminal. Accordingly, the legacy system and the enhanced system can efficiently transmit a control channel.

Abstract: Provided is a method for feeding back a channel quality indicator (CQI) by a terminal. The terminal receives, from a base station, at least one reference signal through at least one of multiple beams of the base station. The terminal measures a signal-to-interference plus noise ratio (SINR) for the at least one reference signal. The terminal determines a first level corresponding to the measured SINR among levels of a first CQI. In addition, the terminal feeds back the first CQI having the first level to the base station.

Abstract: Disclosed is a method for enhancing a small cell. A method for enhancing a small cell in a terminal applying inter-site CA includes the steps of: causing a terminal to transmit the uplink control information (UCI) of at least one of the macro cells controlled by a macro cell base station through the macro cell; and causing the terminal to transmit the uplink control information of at least one of the small cells controlled by a small cell base station through the small cell.

Abstract: In an environment in which a macrocell and a plurality of small cells exist, a terminal receives a discovery signal from a first small cell adjacent to the terminal among the plurality of small cells. When the first small cell is in a predetermined state, the terminal measures RRM of the first small cell based on the discovery signal.

Abstract: A method for transmitting a sounding reference signal (SRS) by a terminal in an environment in which a first carrier corresponding to a first serving cell and a second carrier corresponding to a second serving cell are aggregated is provided. The terminal receives first downlink control information (DCI) which is used for downlink scheduling and includes a first transmit power control (TPC) command through the first serving cell. The terminal controls transmit power of the SRS based on the first TPC command for transmit power control of the SRS. Next, the terminal transmits the SRS through the second serving cell using the controlled transmit power.
