Abstract: A method is provided for generating Acknowledgement/Negative Acknowledgement (ACK/NACK) information at a user equipment in a wireless communication system. The user equipment receives a plurality of codewords corresponding to data blocks through a plurality of downlink carriers from a base station, wherein each of the plurality of downlink carriers carries one or more codewords. The user equipment generates the ACK/NACK information by concatenating ACK/NACK bits corresponding to the plurality of codewords. When a corresponding downlink carrier carries two or more codewords, the ACK/NACK bits corresponding to the two or more codewords associated with the corresponding downlink carrier are concatenated in accordance with an index order of a corresponding data block. The ACK/NACK bits concatenated in accordance with the index order of the corresponding data block associated with each of the downlink carriers are concatenated again in accordance with an index order of a corresponding downlink carrier.

Abstract: Provided is a method for transmitting, by a user equipment (UE), a demodulation reference signal (DMRS) for a physical uplink shared channel (PUSCH) in a wireless communication system. A terminal receives a cyclic shift field, which indicates a first value and a second value, through a physical downlink control channel (PDCCH) from a base station, generates a first DMRS sequence and a second DMRS sequence, which are associated with a first layer and a second layer respectively, by using a first cyclic shift and a second cyclic shift, respectively, which are determined based on the first value and the second value respectively, and transmits the first DMRS sequence and the second DMRS sequence to the base station. Furthermore, the first value and the second value are separated by a maximum value corresponding to a total number of possible cyclic shifts.
