    Abstract: A method is provided for receiving uplink control information (UCI) in a wireless access system supporting a carrier aggregation. An evolved Node-B (eNB) transmits, to a user equipment (UE), two or more physical downlink shared channels (PDSCHs) via two or more downlink component carriers, respectively. The eNB receives, from the UE, the UCI for the two or more downlink component carriers. The UCI includes acknowledgement information and channel quality information (CQI) for each of the two or more downlink carriers. The UCI is performed by using a channel coding with respect to the UCI according to a payload size of the UCI when the UCI is transmitted by using a physical uplink control channel (PUCCH) format 3. The UCI is performed by using a rate matching with respect to the channel coded UCI for the PUCCH format 3.

    Abstract: Disclosed is a method of transmitting a synchronization signal from a moving cell base station in a wireless communication system. The present invention includes mapping a moving cell synchronization signal sequence generated on a basis of a sequence assigned for a moving cell to a frequency region and transmitting the mapped moving cell synchronization signal sequence. Moreover, the moving cell synchronization signal sequence may be mapped to the frequency region different from a prescribed frequency region for transmitting a synchronization signal for a user equipment unsupportive of the moving cell.
