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: In an uplink transmission method of a first communication node, the first communication node receives a reference signal configuration for an UpPTS (uplink pilot time slot) from a second communication node when the UpPTS of a special subframe and a first uplink (UL) subframe are aggregated as an extended UL subframe. Also, the first communication node allocates a reference signal to the first UL subframe of the UpPTS and the first UL subframe based on the reference signal configuration when a number of time domain symbols belonging to the UpPTS is a predetermined number or less.

Abstract: Within one carrier, a base station reserves a first resource area for a first TTI-based transmission in a unit of first TTI within a second TTI period longer than the first TTI, and schedules a first data channel to be transmitted on the basis of the first TTI, in the first resource area.

Abstract: A method for a base station to configure a channel state information (CSI)-reference signal (RS) is provided. The base station configures a CSI-RS antenna port for a terminal. The base station selects one of at least one port number mapping rule for mapping a port number on the CSI-RS antenna port for the terminal. The base station notifies the terminal of the selected port number mapping rule.

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.

Abstract: The transmitter maps an antenna port to a logical antenna port through a first virtualization. The transmitter maps the logical antenna port to a transceiver unit (TXRU) through a first operation. The transmitter maps the TXRU to a logical TXRU through a second operation. The transmitter maps the logical TXRU to a physical antenna element through a second virtualization.
