    Abstract: A method in which a base station transmits a CSI (channel state information)-RS (reference signal) in a MIMO (multiple input multiple output) antenna system is provided. The base station periodically transmits a CSI-RS for first CSI to a terminal. The base station requests the terminal to transmit second CSI in a first subframe. When a CSI-RS occasion is configured, the base station transmits a CSI-RS for the second CSI to the terminal for a duration of the CSI-RS occasion from a second subframe or to the second subframe, which is a subframe after a first offset configured for CSI-RS transmission from the first subframe.

    Abstract: A base station includes a plurality of first resource elements (REs) corresponding to at least two of a second orthogonal frequency division multiplexing (OFDM) symbol, a third OFDM symbol, and a fourth OFDM symbol of a first time slot, in a first CSI-RS resource pool configured in a first subframe including the first time slot and a second time slot subsequent to the first time slot. Furthermore, the base station transmits a CSI-RS at least one of REs included in the first CSI-RS resource pool.

    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.

    Abstract: Disclosed herein are a terminal and an operation method thereof in a MIMO system. The terminal may use a reference signal for channel state measurement from a base station to calculate a first value that is a ratio of a signal transmitted from the base station to noise and a second value that is a ratio of interference from the base station and the noise. Further, the terminal may generate bit information by comparing a ratio of the second value and the first value with a predetermined threshold value and feedback the first value and the bit information to the base station.
