    Abstract: A method is presented of reporting control information in a wireless communication system in which M downlink time divisional duplex (TDD) subframes are associated with an uplink TDD subframe. A user equipment (UE), supporting at least one cell including a primary cell, receives a radio resource control (RRC) message indicating resource allocation information used for a first PUCCH format. The UE receives a first physical downlink shared channel (PDSCH) and a second PDSCH in one of the M downlink TDD subframes, wherein the second PDSCH is received with a downlink assignment index (DAI). The UE selects a physical uplink control channel (PUCCH) format among a plurality of PUCCH formats including the first PUCCH format and a second PUCCH format, and transmits a positive-acknowledgement (ACK)/negative-acknowledgement (NACK) signal for the first and second PDSCHs by using the selected PUCCH format.

    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 in a wireless communication system. A user equipment (UE) transmits first channel information indicating a set of precoding matrices to a base station (BS) periodically, and transmits second channel information indicating one precoding matrix included in the set of precoding matrices to the BS periodically. The second channel information transmitted in a specific subframe is determined based on first channel information that has most recently been transmitted before the specific subframe. Additionally, the UE calculates a channel quality indicator (CQI) transmitted in the specific subframe based on one precoding matrix specified by the first channel information that has most recently been transmitted before the specific subframe and by the second channel information determined based on the first channel information that has most recently been transmitted before the specific subframe.
