    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.

    Abstract: A first terminal receives a first Timing Advance (TA) value from a base station and includes a second TA value that is obtained based on the first TA value in a Scheduling Assignment (SA) signal. The first terminal transmits the SA signal to a second terminal at downlink (DL) timing for receiving a downlink signal of the base station in cellular communication. When a length of a Cyclic Prefix (CP) that is set for the D2D communication and a length of a CP that is set for the cellular communication are different, the first terminal transmits data of the D2D communication to the second terminal at first timing that is obtained by applying the second TA value to the DL timing.

    Abstract translation: 第一终端从基站接收第一定时提前（TA）值，并且包括基于调度分配（SA）信号中的第一TA值获得的第二TA值。 第一终端在下行链路（DL）定时将SA信号发送到第二终端，用于在蜂窝通信中接收基站的下行链路信号。 当针对D2D通信设置的循环前缀（CP）的长度和为蜂窝通信设置的CP的长度不同时，第一终端在第一定时向第二终端发送D2D通信的数据， 通过将第二TA值应用于DL定时来获得。
