Title: MULTI-CARRIER DATA TRANSMISSION METHOD AND APPARATUS
Abstract:
Provided are a multi-carrier data transmission method and apparatus, which introduce an HARQ timing sequence configured by a multi-carrier frame, so that in a carrier aggregation scene, when a first device uses a sub-frame n of a first carrier to send a TB to a second device, the second device determines, according to the HARQ timing sequence configured by the multi-carrier frame, to use a sub-frame m of a second carrier to send a feedback message of the TB. Since the second device may use any one carrier to send the feedback message, the opportunities for the second device to send the feedback message are increased, thereby reducing data transmission delay. Moreover, when the first device retransmits the TB, a carrier, which is different from that used when the TB is initially transmitted, may be used, thereby increasing the opportunities for sending the retransmitted TB and further reducing data transmission delay.
