Abstract: A method whereby a user equipment (UE) transmits hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative ACK (NACK) information corresponding to downlink data received from a corresponding base station (ENB) in a long term evolution-advanced (LTE-A) system supporting carrier aggregation (CA) is provided. When physical uplink shared channel (PUSCH) transmission is not scheduled at the time of transmission of HARQ ACK/NACK information, the UE transmits HARQ ACK/NACK information via physical uplink control channel (PUCCH). When PUSCH transmission is scheduled, the UE transmits HARQ ACK/NACK information multiplexed with PUSCH to the ENB. The amount of HARQ ACK/NACK information increases in proportion to the number of aggregated carriers. The present disclosure specifies scheduling operation of the ENB and HARQ ACK/NACK mapping of the UE that maintain reception performance of HARQ ACK/NACK and PUSCH when HARQ ACK/NACK information is multiplexed with PUSCH.

Abstract: A method and apparatus for transmitting control information to a User Equipment (UE) by an evolved Node B (eNB) for interference measurement in a wireless communication system are provided. The eNB determines whether the UE can perform interference management for receiving a data signal transmitted from the eNB based on information of an interference signal. When it is determined that the UE can perform the interference management, the eNB transmits to the UE configuration information for receiving the data signal by applying the interference management by the UE, and then transmits to the UE downlink control information including transmission power control information indicating whether a transmission power of a DeModulation Reference Signal (DMRS) corresponding to the interference signal is different from a transmission power of the interference signal.
