METHOD FOR TRANSMITTING/RECEIVING SIGNAL AND DEVICE THEREFOR

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting uplink control information and a device therefor, the method comprising the steps of: forming a plurality of serving cells each having different UL-DL configurations; receiving one or more signals requiring a HARQ-ACK response from M(M≧1) number of subframes; and executing the process for transmitting the HARQ-ACK response to the one or more signals in a specific subframe corresponding to the M number of subframes, wherein, only when the specific subframe is set as an uplink in all of the plurality of serving cells, the HARQ-ACK response to the one or more signals are transmitted through the specific subframe.

1. A method for transmitting uplink control information by a user equipment (UE) in a TDD (Time Division Duplex) wireless communication system including a base station (BS) and configured with a plurality of serving cells including a first serving cell having a first UL/DL (Uplink/Downlink) configuration and a second serving cell having a second UL/DL configuration that is different from the first UL/DL configuration, the method comprising:
receiving, by the UE from the BS, a signal in a downlink subframe via the second serving cell having the second UL/DL configuration; and in response to the signal, transmitting a HARQ-ACK (Hybrid Automatic Repeat reQuest-Acknowledgement) response by the UE to the BS in an uplink subframe via the first serving cell or the second serving cell based on one of the first UL/DL configuration and the second UL/DL configuration that has a largest number of downlink subframes when the first serving cell and the second serving cell are determined to be aggregated serving cells.
