    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 of transmitting a reference signal in a wireless communication system; and a user equipment therefore are described. The method according to one embodiment includes selecting one or more values among a set {0, 3, 6, 8, 10}; cyclically shifting a base sequence based on the one or more values selected from the set {0, 3, 6, 8, 10}; and transmitting the reference signal based on the cyclically shifted base sequence to a base station. The reference signal is transmitted on a first orthogonal frequency division multiplexing (OFDM) symbol and a second OFDM symbol. The first OFDM symbol is a second OFDM symbol among 7 OFDM symbols in one slot. The second OFDM symbol is a sixth OFDM symbol among the 7 OFDM symbols in the slot.

    Abstract: A method for a base station (BS) to perform a hybrid automatic repeat request (HARQ). The BS transmits an uplink (UL) grant for a first subframe of a second serving cell through a first serving cell. The BS receives UL data based on the UL grant in the first subframe, transmits an acknowledgement/non-acknowledgement (ACK/NACK) for the UL data through a physical HARQ indicator channel (PHICH) in subframe i of the first serving cell and receives non-adaptively retransmitted UL data in a second subframe of the second serving cell if a NACK for the UL data has been transmitted through the PHICH in the subframe i of the first serving cell. The first serving cell and the second serving cell use different UL-DL configurations.

    Abstract: A method for transmitting channel status information of a user equipment (UE) in a wireless communication system. The UE reports first channel information to a base station periodically; and reports second channel information to the base station periodically. The first channel information and the second channel information are pieces of information combined to indicate one precoding matrix. The second channel information reported in a specific subframe is calculated based on last reported first channel information. A channel quality indicator (CQI) reported in the specific subframe is calculated based on one precoding matrix indicated by the last reported first channel information and the second channel information reported in the specific subframe.
