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: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting acknowledgement/negative ACK (ACK/NACK) in a wireless communication system which supports carrier aggregation, and to an apparatus for the method. A method in which a terminal transmits ACK/NACK in a wireless communication system that supports carrier aggregation comprises the following steps: receiving one or more physical downlink shared channels (PDSCHs); and transmitting ACK/NACK for said one or more PDSCHs via a physical uplink control channel (PUCCH). A PUCCH format for transmitting ACK/NACK is selected by taking the type of the carrier in which said one or more PDSCHs are received into account.

Abstract: A method for transmitting channel status information (CSI) of downlink multi-carrier transmission includes generating the CSI including at least one of a rank indicator (RI), a first precoding matrix index (PMI), a second PMI and a channel quality indicator (CQI) for one or more downlink carriers, the CQI being calculated based on precoding information determined by a combination of the first and second PMIs, determining, when two or more CSIs collide with one another in one uplink subframe of one uplink carrier, a CSI to be transmitted on the basis of priority, and transmitting the determined CSI over a uplink channel. If a CSI including an RI or a wideband first PMI collides with a CSI including a wideband CQI or a subband CQI, the CSI including a wideband CQI or a subband CQI has low priority and is dropped.

Abstract: Embodiments of the present invention are directed to a method and apparatus for transmitting and receiving a control signal (for example, PDCCH signal) in an asymmetric multicarrier environment. The method for transmitting a control signal for an asymmetric multicarrier in a wireless connection system according to one embodiment of the present invention comprises: determining the size of a carrier indicator field (CIF) indicating a downlink component carrier (DL CC) by which downlink data is transmitted, on the basis of a maximum value of the number of DL CCs and of the number of uplink component carriers (UL CCs) being managed in a base station; transmitting the CIF on a 1st DL CC to a terminal through a physical downlink control channel (PDCCH); and transmitting downlink data on a 2nd DL CC indicated by the CIF to the terminal through a physical downlink shared channel (PDSCH).

Abstract: A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information at a User Equipment (UE) in a wireless communication system. The UE determines whether a transmission of a scheduling request is configured in one uplink subframe in which ACK/NACK information for downlink transmissions is to be transmitted, when a Physical Uplink Control Channel (PUCCH) format 3 is configured for a transmission of the ACK/NACK information, and transmits the ACK/NACK information using a PUCCH format 1a/1b and a PUCCH resource. If the transmission of the ACK/NACK information coincides with the one uplink subframe for the transmission of the scheduling request, the UE transmits ACK/NACK information and the scheduling request in the one uplink subframe by using the PUCCH format 1a/1b, when the ACK/NACK information corresponds only to a Physical Downlink Shared Channel (PDSCH) received only on a Primary Cell (PCell).
