Abstract: An uplink transmission method in a wireless communication system, and a user equipment (UE) therefore, are discussed. The method includes, for example, generating uplink control information (UCI) which includes at least one of a hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative-acknowledgement (NACK) signal, a channel quality indicator (CQI) and a scheduling request (SR); generating a reference signal (RS) based on one or more indices selected from among a set {0, 3, 6, 8, 10}; transmitting the UCI on a physical uplink control channel (PUCCH); and transmitting the generated RS for the PUCCH based on the selected one or more indices.

Abstract: A method and user equipment for performing an uplink transmission in a wireless communication system, are discussed. The method includes allocating transmission power to a first uplink transmission and a second uplink transmission when a total power in a transmission period including at least one or more OFDM symbols exceeds maximum power, wherein each of the first and second uplink transmissions is one of physical uplink shared channel (PUSCH) transmission, physical uplink control channel (PUCCH) transmission, physical random access channel (PRACH) transmission and sounding reference signal (SRS) transmission; and performing the first and second uplink transmissions according to the allocated transmission power, wherein the allocation of the transmission power is performed according to priority information.

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 is provided for performing, by a first device, channel coding of data to be transmitted to a second device. The first device determines a size of a transport block for the data, attaches a first cyclic redundancy check (CRC) code to the transport block having the determined size to produce a first CRC-attached transport block, and segments the first CRC-attached transport block into multiple code blocks when a size of the first CRC-attached transport block is larger than a predetermined size. The size of the transport block is determined from among a plurality of predetermined transport block sizes, and the plurality of predetermined transport block sizes are predetermined such that all the multiple code blocks have a same size as each other.

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.
