Abstract: Provided in one disclosure of the present specification is a method for transmitting a hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative-acknowledgement (NACK) for downlink data, when more than five cells are used according to carrier aggregation (CA) by a user equipment (UE). The method comprises the steps of: receiving, from a base station, a list of sets of which HARQ-ACK/NACK transmission is limited, through an upper layer signal; receiving, from the base station, information indicating a set of which HARQ-ACK/NACK transmission is limited at the present turn, from among the list of sets; receiving, from the base station, a plurality of items of downlink data through a plurality of cells; determining the set of which transmission is limited based on the information, from among the list of sets that has been received through the upper layer signal; and generating and transmitting uplink control information (UCI) including HARQ-ACK/NACK for the downlink data but excluding the HARQ-ACK/NACK according to the set which has been determined.

Abstract: A disclosure of the present specification provides a method for transmitting a sounding reference signal (SRS) by a terminal. The method may include the steps of: receiving an SRS configuration from a base station by the terminal; on the basis of the received SRS configuration, determining an SRS sub-frame to which an SRS is to be transmitted among a plurality of sub-frames, and an SRS transmission region to which an SRS is to be transmitted in a physical uplink control channel (PUCCH) region on the SRS sub-frame; and transmitting the SRS to the SRS transmission region on the determined SRS sub-frame, wherein when the SRS and a PUCCH are transmitted simultaneously to the SRS transmission region, the SRS and the PUCCH may be multiplexed on the basis of code division multiplexing (CDM).

Abstract: Disclosed are a method and an apparatus for transmitting uplink data by means of multiple serving cells. A method for a terminal for transmitting uplink data by means of multiple serving cells may comprise the steps of: the terminal receiving a first timing advance command (TAC) for a first serving cell and a second TAC for a second serving cell; and determining whether the terminal transmits uplink data by means of the second serving cell on the basis of whether the timing difference is below the threshold value, wherein the timing difference is acquired on the basis of the first TAC and the second TAC, and the first serving cell can be a cell configured so that an uplink can be always transmitted regardless of the timing difference.

Abstract: A method for and apparatus for transmitting uplink transmission in a wireless communication system supporting multiple carriers is provided. A wireless device transmits the uplink transmission via an alternative Primary serving cell or Secondary serving cell in uplink between the UE and the eNB. Herein the uplink transmission is configured by enabling information with corresponding serving cell as the Primary serving cell or the Secondary serving cell for the uplink transmission. And then, a PUCCH and/or PUSCH can performed on the enabling serving cell and/or cells in consideration of power control more accurately and efficiently.

Abstract: A method and device for supporting a hybrid automatic repeat request (HARQ) in an unlicensed band is provided. A user equipment receives first downlink control information (DCI) including uplink scheduling information. The first DCI further includes a carrier indicator field (CIF) indicating a cell to be scheduled. If the type of the cell indicated by the CIF is a licensed cell, the format of the DCI is determined as a first DCI format including a first resource allocation (RA) field used for the uplink scheduling information. If the type of the cell indicated by the CIF is an unlicensed cell, the format of the DCI is determined as a second DCI format including a second RA field used for the uplink scheduling information.
