    Abstract: A method, and a user equipment (UE), for transmitting control information. The method according to one embodiment includes receiving a sounding reference signal (SRS) simultaneous transmission parameter; and if the SRS simultaneous transmission parameter is true, transmitting an SRS, and, in cell specific SRS subframes of a primary component carrier, a physical uplink control channel (PUCCH) which coincides in a same subframe as the SRS. The PUCCH using a shortened format carries at least one of a HARQ-ACK and a positive scheduling request (SR). The method according to the embodiment further includes, if the SRS simultaneous transmission parameter is false, transmitting the PUCCH which uses a normal PUCCH format and carries at least one of the HARQ-ACK and the positive SR, while not transmitting, in a secondary component carrier, the SRS which coincides in the same subframe. The transmitting of the PUCCH uses carrier aggregation.

    Abstract: A method for transmitting ACK/NACK (Acknowledge/Negative ACK) information for two or more carriers at a user equipment in a wireless communication system which supports carrier aggregation. The method according to one embodiment includes generating an ACK/NACK payload including two or more ACK/NACK sets, wherein each ACK/NACK set is associated with a corresponding carrier and have one or more ACK/NACK bits; and transmitting the ACK/NACK payload through a PUCCH (Physical Uplink Control Channel) or PUSCH (Physical Uplink Shared Channel). A size of the ACK/NACK payload is given based on carrier configuration, the carrier configuration including a number of configured carriers and transmission modes for the configured carriers. The two or more ACK/NACK sets are concatenated in an order of carrier index.

    Abstract: A method is described 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 cyclic shift field is received through a physical downlink control channel (PDCCH) from a base station. The cyclic shift field indicates first, second, third and fourth cyclic shifts, first orthogonal cover code (OCC) and a second OCC. A first DMRS sequences is generated by using the first cyclic shift and the first OCC. A second DMRS sequence is generated by using the second cyclic shift and the first OCC. A third DMRS sequence is generated by using the third cyclic shift and the second OCC. A fourth DMRS sequence is generated by using the fourth cyclic shift and the second OCC. The first, second, third and fourth DMRS sequences are transmitted to the base station.
