Abstract: One disclosure of the present specification provides a method for operating a HARQ from user equipment (UE). The method comprises the steps of: the UE receiving downlink data from each cell, when at least one TDD-based cell and at least one FDD based cell are established according to carrier aggregation (CA), a specific TDD-based cell is established as a primary cell of the carrier aggregation (CA), and the at least one FDD-based cell is established as a secondary cell of the carrier aggregation (CA); the UE confirming a PUCCH format to be used for transmitting a HARQ ACK/NACK for the downlink data; and the UE determining the number of bits for transmitting the HARQ ACK/NACK when use of the specific PUCCH format for transmitting the HARQ ACK/NACK is confirmed.

Abstract: A method for requesting an uplink scheduling is provided. In the case that there is an SR PUCCH resource established on a secondary cell, not an SR PUCCH resource established on a primary cell, and a special secondary cell is in a state of de-activation at the time of sending an uplink scheduling request, the uplink scheduling request is stopped and a random access procedure is initiated. If the uplink scheduling request can be sent on a plurality of cells at the same point of time, that is, if there are a plurality of uplink resources available for the uplink scheduling request at the same point of time, the uplink scheduling request is sent only on one of the plurality of cells (and using only one uplink resource).

Abstract: The present invention relates to a method for receiving a downlink control signal in a TDD-based wireless communication system, and to an apparatus therefor. The method comprises receiving a downlink signal via a downlink interval in a specific frame including the downlink interval, a guard interval and an uplink interval. A combination of the downlink interval, the guard interval and the uplink interval is given using configuration information on the specific subframe. When the configuration information is given such that the length of the downlink interval is larger than a specific value, detecting a first type of PDCCH is performed in the specific subframe. When the configuration information is given such that the length of the downlink interval is equal to or smaller than the specific value, detecting the first type of PDCCH is skipped in the specific subframe.

Abstract: Provided are a method and an apparatus for transmitting/receiving scheduling information for one cell (a particular cell) from among a plurality of cells under a carrier aggregation condition in which a plurality of cells are aggregated. One embodiment according to the present invention transmits/receives a downlink grant for the particular cell from a first cell from among the plurality of cells, and transmits/receives an uplink grant for the particular cell from a second cell, from among the plurality of cells, which is different from the first cell. The particular cell may be a different cell from the first and second cells, or may be the same cell as the first cell or the second cell.

Abstract: Provided are a method for transmitting data in an unlicensed band and a device using the same. A transmission node generates a signal to be transmitted in the unlicensed band, and performs listen before talk (LBT) according to the type of the generated signal. If a wireless medium is idle as a result of the LBT, the transmission node transmits the generated node in the unlicensed band.

Abstract: A method for a wireless device to which a plurality of serving cells are assigned transmitting uplink control information (UCI) in a wireless communication system is provided. The wireless device transmits uplink data in a subframe to a physical uplink shared channel (PUSCH), and transmits UCI including a hybrid automatic repeat request (HARQ) ACK/NACK and periodic channel state information (CSI) in the subframe to a physical uplink shared channel (PUCCH). The PUCCH and the PUSCH have the same demodulation reference signal (DMRS) location within the subframe.

Abstract: The present invention relates to a wireless access system supporting an unlicensed band and provides methods for performing a channel access process for transmitting different types of signals, and devices supporting the same. According to one embodiment of the present invention, a method for transmitting different types of signals in a wireless access system supporting an unlicensed band can comprise the steps of: performing a first channel process (CAP) for transmitting a first type of signal; and transmitting a transmission burst including the first type of signal through the unlicensed band if it is determined that a serving cell (SCell) of the unlicensed band is in an idle state after performing the first CAP. At this time, at least one of first parameters for performing the first CAP can be set to be value less than that of second parameters for performing a second CAP for transmitting a second type of signal.
