Abstract: A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information in a wireless communication system. A User Equipment (UE) configures a Physical Uplink Control Channel (PUCCH) format 3 for transmission of the ACK/NACK information. The UE transmits the ACK/NACK information for downlink transmission in a downlink subframe set including M downlink subframes in one uplink subframe, wherein M>1. A plurality of serving cells are configured for the UE and include one Primary Cell (PCell) and at least one Secondary Cell (SCell). The UE transmits the ACK/NACK information using a PUCCH format 1b when a first condition is met that comprises a condition in case where the ACK/NACK information corresponds to one Physical Downlink Shared Channel (PDSCH) without a corresponding Physical Downlink Control Channel (PDCCH) received only on the PCell in the downlink subframe set and the ACK/NACK information corresponds to an additional PDSCH indicated by detection of one corresponding PDCCH.

Abstract: A method for transmitting information data by using a Reed-Muller coding scheme in a wireless communication system is disclosed. The method includes configuring a number of resource elements for transmitting the information data; dividing the information data to first information data and second information data if a bit size O of the information data is equal to or larger than a predetermined number; applying RM coding on each of the first information data and the second information data; concatenating the coded first information data and the coded second information data, and transmitting the concatenated data by using the predetermined number of resource elements, wherein a minimum value Q′min for the number of resource elements is defined by a sum of a minimum value Q′min_1 for the number of resource elements corresponding to the first information data and a minimum value Q′min_2 for the number of resource elements corresponding to the second information data.

Abstract: A method of configuring a measurement for a mobile terminal configured with a plurality of component carriers in a wireless communication system is discussed. The method is performed by a base station and includes transmitting, by the base station, configuration information to the mobile terminal. Further, when the transmitted configuration information includes an indication information for the measurement in an extension component carrier among the plurality of component carriers, the measurement in the extension component carrier is based on a channel state information reference signal (CSI-RS), and when the transmitted configuration information does not include the indication information for the measurement in the extension component carrier among the plurality of component carriers, the measurement in the extension component carrier is based on a common reference signal (CRS).

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.
