摘要： The present invention relates to a method for transmitting/receiving data in a Time Division Duplex (TDD) wireless access system supporting multiple cells, and a base station for same. In more detail, on the basis of a multi-cell TDD uplink-downlink configuration, the method includes confirming whether a collision subframe occurs, which is caused when an uplink subframe of a first cell and a downlink subframe of a second cell exists in the same time interval; and performing cross cell scheduling on the second cell through the first cell according to a TDD uplink-downlink configuration of the first cell. When data transmission is scheduled in the collision subframe by cross cell scheduling, by changing the transmission position of an uplink or a downlink according to the cross cell scheduling, the scheduled data are transmitted in the collision subframe.

摘要： The present invention relates to a wireless communication system, and more specifically, to a method and a device for transmitting/receiving uplink control information. The method for a terminal to transmit confirmation response information in a wireless communication system according to one embodiment of the present invention comprises: a step for determining a PUCCH (physical uplink control channel) format and resource, in which confirmation response information is transmitted in response to a downlink transmission in a downlink sub-frame set including M(M≥1)downlink sub-frame; and a step for transmitting the confirmation response information using the PUCCH format and resource in one uplink sub-frame. Here, one excess serving cell is set to a terminal, and the one excess serving cell can include one PCell and at least one SCell. The confirmation response information can be transmitted using a PUCCH format 1a/1b when one PDSCH (physical downlink shared channel), from which a corresponding PDCCH (physical downlink control channel) is not detected, exists only on PCell in the downlink sub-frame set, and a SPS (semi-persistent scheduling) releasing PDCCH does not exist in the downlink sub-frame set.
