Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting uplink channel state information (CSI) in a wireless communication system that supports carrier aggregation, and to an apparatus for the method. The method for reporting CSI in a wireless communication system that supports carrier aggregation comprises the steps of: configuring a plurality of downlink component carriers (DL CCs); setting a CSI report mode on the plurality of DL CCs for each DL CC; and performing an operation for transmitting CSI according to the CSI report mode set on each DL CC. If a P-number of CSI overlap in the same subframe and a first condition is satisfied, a Q-number of CSI among the P-number of CSI are transmitted through a first physical channel, and if the P-number of SCI overlap in the same subframe and a second condition is satisfied, only an R-number of CSI among the P-number of CSI are transmitted through a second physical channel which is different from the first physical channel, wherein R is smaller than Q.

Abstract: According to one embodiment, a distance technique between a transmitter and a receiver for processing a signal in symbol units is presented. According to the embodiment, the transmitter transmits a transmission signal to the receiver through preset first and second frequencies. Then, the transmitter receives, from the receiver, a reception signal corresponding to the transmission signal. The reception signal includes a first reception component corresponding to the first frequency and a second reception component corresponding to the second frequency. The phase difference set by the receiver is applied between the phase of the first reception component and the phase of the second reception component. The phase difference is set on the basis of the difference between a reception time at which the transmission signal is received by the receiver and a processing time at which the transmission signal is processed in the receiver.
