METHOD FOR ENABLING TERMINAL TO TRANSMIT AND RECEIVE SIGNAL IN WIRELESS COMMUNICATIONS SYSTEM AND APPARATUS THEREFOR

摘要

The present invention relates to a method for enabling a terminal to transmit and receive a signal in a wireless communications system and an apparatus therefor. More specifically, the method includes the steps of: receiving physical downlink shared channel (PDSCH) data and reconfiguration downlink control information (DCI); and transmitting at least one of the information of ACK/NACK(acknowledgement/Negative Acknowledgement) for downlink data and the answer message corresponding to the reconfiguration downlink control information, characterized in that the answer message represents whether to succeed in receiving the reconfiguration downlink control information.
