Title: DATA TRANSMISSION METHOD, TRANSMITTING DEVICE, AND RECEIVING DEVICE
Abstract:
The present invention provides a data transmission method, a transmitting device, and a receiving device, which relate to the field of communications and can maximally satisfy transmission needs for different sub-bands, thereby improving system throughput. The method comprises: a transmitting device determining rank indications of J (J is an integer greater than or equal to one) sub-bands corresponding to a channel to be transmitted, in which the rank indications of the J sub-bands are not exactly the same; the transmitting device respectively determining, according to the rank indication of each of the J sub-bands, a transport block size (a transport block size corresponding to the J sub-bands or a transport block size corresponding to each of the J sub-bands) and a number of transport layers corresponding to each of the sub-bands; mapping, according to the rank indication of each of the J sub-bands, a transport block corresponding to the sub-band to the transport layer corresponding to the sub-band; and performing transmission after data carried on the transport layer corresponding to each of the sub-bands is mapped to a time-frequency resource.
