Abstract: Provided are a method and an apparatus for transmitting uplink control information performed by a user equipment in a wireless communication system. The method comprises the steps of: receiving a first parameter for indicating whether to simultaneously transmit a first combination of an acknowledgement/negative-acknowledgement (ACK/NACK) and a channel quality indicator (CQI), and a second parameter for indicating whether to multiplex a second combination of an ACK/NACK and the CQI and transmitting same as a second physical uplink control channel (PUCCH) format; and multiplexing the first combination of the ACK/NACK or the second combination of ACK/NACK with the CQI and transmitting same as a first PUCCH format or the second PUCCH format, based on the first parameter and the second parameter.

Abstract: A method and device for transmitting or receiving an Acknowledgement/Negative-ACK (ACK/NACK) signal in a wireless communication system are discussed. The method of transmitting includes receiving scheduling information from a base station through a physical downlink control channel; receiving a data unit from the base station through a physical downlink shared channel based upon the scheduling information; determining an uplink resource index for transmitting the ACK/NACK signal for the data unit; and transmitting the ACK/NACK signal to the base station by using an uplink resource indicated by the uplink resource index, wherein the uplink resource index is determined by using index modification information, a smallest value of resource indexes used for the physical downlink control channel, and a value transferred from an upper layer, and wherein the index modification information is signaled through the physical downlink control channel.

Abstract: The present invention relates to a method and apparatus for transmitting an acknowledgement/not-acknowledgement (ACK/NACK) signal in a wireless communication system. The method includes the steps of: receiving a transmission block; and transmitting an ACK/NACK signal for the transmission block in a first subframe or a second subframe according to the size of the transmission block, wherein, when the size of the transmission block is smaller than or equal to a reference value, the ACK/NACK signal is transmitted in the first frame, when the size of the transmission block is greater than the reference value, the ACK/NACK signal is transmitted in the second subframe, and the second subframe is behind the first subframe in a time domain.

Abstract: Provided are a method and an apparatus for transmitting uplink control information (UCI), which is carried out by a terminal in a wireless communication system. If the number of information bits of the UCI falls inside a specific range when different types of UCI are transmitted through the same PUCCH format, a bit sequence of each of the UCI are channel-coded by aligning/interleaving, wherein the aligning/interleaving is carried out so that the UCI having high importance are channel-coded so as to have better decoding performance.

Abstract: A method for efficiently scheduling virtual resource blocks to physical resource blocks is disclosed. In a wireless mobile communication system, for distributed mapping of consecutively allocated virtual resource blocks to physical resource blocks, when nulls are inserted into a block interleaver used for the mapping, they are uniformly distributed to ND divided groups of the block interleaver, which are equal in number to the number (ND) of physical resource blocks to which one virtual resource block is mapped.

Abstract: Provided is a method and an apparatus for transmitting uplink control information by a terminal in wireless communication system. When a PUCCH resource used for transmitting only periodic CSI from a subframe, the resource is a first resource, and a resource indicated by ARI is a second resource, when a setting allows transmitting together ACK/NACK and the periodic CSI through a PUCCH from the same subframe, the first resource and the second resource are mutually exclusive, and the second resource that is used for transmitting together the ACK/NACK and the periodic CSI uses the resource indicated by the ARI from resources determined by an RRC.
