Abstract: The present invention determines a PUCCH resource based on which serving cell ACK/NACK information is related to, when a user device set as a plurality of serving cells transmits the ACK/NACK information. Moreover, if a PUCCH transmission time matches with a PUSCH transmission time, the present invention does not piggy back ACK/NACK information to PUSCH but transmits the ACK/NACK information through PUCCH.

Abstract: The present invention relates to a wireless communication system. In particular, the present invention relates to a method and an apparatus for receiving data, by a terminal, in a wireless communication system, the method comprising the steps of: receiving a PDCCH; receiving a PDSCH corresponding to the PDCCH in a subframe including CSI-RS resource available in a cell; and demodulating the PDSCH. If a predetermined condition is satisfied, demodulation of the PDSCH is performed on the assumption that the PDSCH is not transmitted in the CSI-RS resource available in the cell, and if the predetermined condition is not satisfied, the demodulation of the PDSCH is performed on the assumption that the PDSCH can be transmitted in the CSI-RS resources available in the cell.

Abstract: Disclosed are a method and an apparatus for transceiving a reference signal in a wireless communication system. The present invention discloses a scheme for transceiving the reference signal the reference signal that is selectively added based on the capacity and characteristics of a terminal. The added reference signal may include newly defined CRS, DM-RS, TRS, MBSFN-RS or new RS or the like for cell recognition of the terminal, synchronization signal, measurement, etc. The location of a specific symbol/frequency of the like and selective power boosting are also disclosed for the added reference signal. Further, the transmission density of RS can be adaptively and selectively channel and transmitted as needed.

Abstract: A method for and apparatus for supporting a control plane (C-plane) and a user plane (U-plane) in a wireless communication system supporting multiple carriers is provided. A wireless device configures a cell for the U-plane to receive and transmit data, determines to enable a User Plane Reception Period (U-RP) corresponding to the cell for the U-plane, and determines to receive and transmit data with the cell for the U-plane during the enabled U-RP. The cell for the U-plane includes at least one or more serving cells, and the cell for the U-plane has a different frequency from a cell for the C-plane.
