Abstract: The present invention discloses a method for transmitting a reception acknowledgement response in a wireless communication system. The method includes receiving an enhanced physical downlink control channel (EPDCCH), determining a physical uplink control channel (PUCCH) resource based on a lowest one of enhanced control channel element (ECCE) indexes configuring the EPDCCH and a HARQ-ACK resource offset (ARO), and transmitting a reception acknowledgement response through the PUCCH resource. When a reception acknowledgement response related to two or more subframes is transmitted in a subframe for transmission of the reception acknowledgement response, a set of possible values for the ARO includes a first ARO value to shift a PUCCH resource of a specific subframe to a PUCCH resource region for at least one subframe prior to the specific subframe. The first ARO value provides a different shift amount depending on a group having the specific subframe among groups related to the two or more subframes.

Abstract: Provided is a method and an apparatus for transmitting a random access preamble in a time division duplex (TDD)-based wireless communication system. A wireless device selects an UL subframe in which a random access preamble is to be transmitted in a first serving cell. If the next subframe following the selected UL subframe is a DL subframe and the length of the random access preamble exceeds the UL subframe, the random access preamble may be generated such that the length of the random access preamble may not exceed the UL subframe.
