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.

1. In a user equipment of a wireless communication system, a method of transceiving signals, comprising the steps of:
receiving downlink data (physical downlink shared channel, PDSCH) and a reconfiguration downlink control information (reconfiguration DCI); and transmitting at least one of an ACK/NACK (acknowledgement/negative acknowledgement) information in response to the downlink data and a confirmation message in response to the reconfiguration downlink control information, wherein the confirmation message indicates success or failure in receiving the reconfiguration downlink control information.
