DATA TRANSMISSION METHOD AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/052388

Kind Code:

A1

Abstract:

The present application provides a data transmission method and device. The method comprises: a sending side device obtains modulation symbol sequences to be transmitted in multiple time-frequency resource unit groups, the sizes of the time-frequency resource unit groups being determined according to a protocol or the sizes of the time-frequency resource unit groups being determined according a transmission parameter; the sending side device performs interleaving processing on the modulation symbol sequences by using the time-frequency resource unit groups as interleaving units, and obtains an order of the modulation symbol sequences mapped in the multiple time-frequency resource unit groups, continuous multiple modulation symbol groups in the modulation symbol sequences being mapped to at least two time-frequency resource unit groups in the multiple time-frequency resource unit groups; and the sending side device sends the modulation symbol sequences according to the order of the modulation symbol sequences mapped in the multiple time-frequency resource unit groups. By means of embodiments of the present application, the computing complexity of a chip in processing can be simplified, thereby resolving the problem in the prior art of high complexity when interleaving is performed by using a CB as a unit.
