Method for transmitting and receiving a signal, and apparatus therefor |
摘要 |
The present invention relates to a wireless communication system. Specifically, a method for transmitting an uplink signal in a wireless communication system supporting carrier aggregation includes the steps of: setting a first cell of a first time division duplex (TDD) uplink (UL)-downlink (DL) configuration, and a second cell of a second TDD UL-DL configuration; receiving data over a DL subframe of the first cell; and transmitting a control signal over a UL subframe of the second cell in response to the received data, wherein a relationship of the DL subframe and UL subframe is determined by parameter values set in a specific TDD UL-DL configuration in a TDD WL-DL configuration set, the specific TDD UL-DL configuration has the minimum number of DL subframes from among one or more of TDD UL-DL configurations in which subframes set as a DL or X are all set as the DL in the first cell or the second cell, the subframes set as X have different subframe directions in the first cell and the second cell at a corresponding subframe timing, and the uses thereof are limited in either the first cell or the second cell. |

1. A method for transmitting an uplink (UL) signal by a user equipment (UE) in a wireless communication system supporting carrier aggregation, the UE being configured with a plurality of cells including a first cell and a second cell, the first cell and the second cell operating in time division duplex (TDD) and having different TDD uplink-downlink (UL-DL) configurations, the method comprising:
receiving, by the UE, at least one downlink signal in at least one DL subframe of the first cell; and transmitting, by the UE, a control signal in a UL subframe of the second cell in response to reception of the at least one downlink signal, wherein a relationship between the at least one DL subframe of the first cell and the UL subframe of the second cell is determined according to a TDD UL-DL configuration having a smallest number of DL subframes from among one or more TDD UL-DL configurations in which each subframe configured as a DL subframe on the first cell or the second cell is configured as a DL subframe. |
