Title: DATA TRANSMISSION METHOD, DATA RECEIVING METHOD, TRANSMITTING DEVICE, AND RECEIVING DEVICE
Abstract:
Provided in embodiments of the present application are a data transmission method, data receiving method, transmitting device, and receiving device. The data transmission method provided in the embodiments of the present application can comprise: performing scrambling initialization to generate scrambling code; performing, according to the scrambling code, scrambling on a data block; repeatedly transmitting the scrambled data block; if the interval since the last scrambling initialization of the data block is greater than or equal to a predetermined parameter threshold for scrambling initialization, then performing scrambling initialization to re-generate scrambling code; performing, according to the re-generated scrambling code, scrambling on the data block again; and repeatedly transmitting the re-scrambled data block. The embodiments of the present application enable efficiency improvement of data transmission between a transmitting device and a receiving device.
