Abstract:
1. A method for transmitting uplink control information in a TDD (Time Division Duplex) wireless communication system configured with a plurality of serving cells including a first serving cell and a second serving cell, the method comprising: receiving, by a user equipment (UE) from a base station (BS), a signal in a downlink subframe via the second serving cell; and in response to the signal, transmitting a HARQ-ACK (Hybrid Automatic Repeat reQuest-Acknowledgement) response to the BS by the UE in an uplink subframe via the first serving cell or the second serving cell in accordance with a reference uplink-downlink (UL-DL) configuration that is based on a relationship between an UL-DL configuration of the first serving cell and an UL-DL configuration of the second serving cell as described in the following Table 1, where the reference UL-DL configuration is defined in the following Table 2 which shows, for a HARQ-ACK response UL subframe having a subframe number, an interval between the HARQ-ACK response UL subframe and the DL subframe associated with the HARQ-ACK response UL subframe from the perspective of the HARQ-ACK response UL subframe,
