Abstract: Provided are a method and an apparatus for a user equipment, which is allocated a plurality of serving cells, receiving acknowledgement/negative acknowledgement (ACK/NACK) in a wireless communication system. The method comprises: transmitting uplink data through a physical uplink shared channel (PUSCH); and receiving ACK/NACK with respect to the uplink through a physical hybrid-ARQ indicator channel (PHICH), wherein a serving cell that receives the ACK/NACK is selected from one or more serving cells, which the user equipment monitors to detect an uplink grant that schedules the PUSCH.

Abstract: According to one embodiment, a method for transmitting an uplink signal includes transmitting the uplink signal including a block of data symbols. The block of data symbols are mapped to at least two sets of subcarrier blocks. Each data symbol of the block of data symbols is mapped to one of subcarriers of the at least two sets of subcarrier blocks. The at least two sets of subcarrier blocks are not contiguous in frequency. The block of data symbols are mapped in sequence starting with a first data symbol to the at least two sets of subcarrier blocks and in increasing order of subcarrier index.

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.

Abstract: A method is provided for performing a hybrid automatic repeat request (HARQ) by a user equipment (UE). An uplink (UL) grant for a first subframe of a second serving cell is received through a first serving cell. UL data in the first subframe of the second serving cell is transmitted according to the UL grant. When a not-acknowledgement (NACK) for the UL data is received through a physical HARQ indicator channel (PHICH) in a subframe i of the first serving cell, the UE performs a non-adaptive retransmission for the UL data in a second subframe of the second serving cell. When a PHICH resource corresponding to the UL data is not present in the subframe i, the UE does not perform the non-adaptive retransmission in the second subframe of the second serving cell.
