Abstract: Method for generating reference signal sequence using grouping is explained. In this method, base sequences are grouped such that each group contains at least one base sequence of each length, so UE(s) can use various length sequences as a reference signal. And in this method, inter cell interference caused by using various length sequence as a reference signal sequence can be minimized by grouping sequences having the high cross correlation relation.

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.
