Abstract: A method for transmitting information data by using a Reed-Muller coding scheme in a wireless communication system is provided. The method includes configuring a number of resource elements for transmitting the information data; generating coded information data having a specific bit size by applying RM coding to the information data; performing rate matching to the coded information data so that the rate-matched information data can correspond to the configured resource elements; and transmitting the rate-matched information data by using the configured number of resource elements, where a minimum value Q′min for the number of resource elements is defined based upon a bit size (O) of the information data and based upon a bit size per symbol (Qm) in accordance with a modulation order.

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.
