METHOD AND DEVICE FOR EXECUTING HARQ IN TDD-BASED WIRELESS COMMUNICATION SYSTEM |
摘要 |
Provided are a method and a device for executing a hybrid automatic repeat request (HARQ) of a terminal in a time division duplex (TDD)-based wireless communication system. The method comprises the steps of: receiving an uplink grant for a first subframe of a second serving cell through a first serving cell; transmitting uplink data in the first subframe on the basis of the uplink grant; receiving an acknowledgement/not-acknowledgement (ACK/NACK) for the uplink data through the first serving cell; and, when the ACK/NACK signal is a NACK, transmitting a retransmission data for the uplink data in a second subframe of the second serving cell. |
