DATA TRANSMISSION METHOD, APPARATUS AND DEVICE FOR MULTI- TRANSMISSION TIME INTERVAL (TTI) SYSTEM

WIPO Patent Application WO/2017/107717

A1

Provided is a data transmission method for a multi-transmission time interval (TTI) system, comprising: generating a data frame including a self-contained feedback; and transmitting the data frame on a plurality of sub-bands into which a carrier is divided, wherein at least two sub-bands of the plurality of sub-bands have different TTIs, the parameters of the self-contained feedbacks of the at least two sub-bands of the plurality of sub-bands are the same, and the time lengths of the self-contained feedbacks of the plurality of sub-bands are the same. By configuring a self-contained feedback across sub-bands, the problem that the resource utilization rate of the self-contained feedback of each sub-band is excessively low due to the fact that TTIs and waveform parameter configurations are different can be solved. By means of the embodiments of the present invention, the resource utilization rate of the self-contained feedback can be improved.
