HARQ ACK/NACK TRANSMISSION METHOD AND WIRELESS DEVICE

摘要

Provided are a method for transmitting a hybrid automatic repeat request (HARQ) positive-acknowledgement (ACK)/negative-acknowledgement (NACK) in a wireless communication system and a wireless device using the same. A resource of an uplink control channel used for the transmission of the HARQ ACK/NACK is determined according to the format of downlink control information.

主权项

1. A method for transmitting hybrid automatic repeat request (HARQ) positive-acknowledgement (ACK)/negative-acknowledgement (NACK) in a wireless communication system, the method comprising:
receiving, by a wireless device, downlink control information on a downlink control channel; receiving, by the wireless device, a downlink transport block on a downlink shared channel according to the downlink control information; and transmitting, by the wireless device, ACK/NACK for the downlink transport block on an uplink control channel, wherein a radio resource for the uplink control channel is determined according to a format of the downlink control information.
