Abstract: A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information at a User Equipment (UE) in a wireless communication system. The UE is configured to use a Physical Uplink Control Channel (PUCCH) format 3 for the transmission of the ACK/NACK information. A PUCCH format between a PUCCH format 1a/1b and the PUCCH format 3 is determined for transmission of the ACK/NACK information for downlink transmission in a downlink frame set including M downlink subframes is to be transmitted, where M≧1, in one uplink subframe, according to whether at least one of specific conditions is met. The ACK/NACK information is transmitted using the determined PUCCH format in the one uplink subframe. The ACK/NACK information is transmitted by using the PUCCH format 1a/1b, when at least one of the specific conditions is met. One serving cell is configured for the UE.

Abstract: The present invention relates to a wireless access system supporting millimeter waves (mmWave) and provides methods for performing fast fallback so as to avoid link disconnections and devices for supporting same. The method whereby a legacy base station supports the fast fallback of a mmWave terminal in a wireless access system supporting millimeter waves (mmWave), according to one embodiment of the present invention, may comprise the steps of: receiving, from the mmWave terminal, a first fallback request message for requesting fast fallback; operating a fallback timer for determining whether or not to perform fallback after receiving the first fallback request message; and determining whether or not a second fallback request message for requesting fast fallback has been received from a mmWave base station within the fallback timer.
