    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.
