Patent ID: 10826557

Abstract:
Disclosed in the embodiments of the present invention is a data transmission method. The method includes: a transmitter transmitting, on a first time frequency resource region, transmission signals that are generated from a bit sequence B using at least a symbol extension technology; the extension sequence used by the symbol extension technology being the Index1-th sequence of a sequence set containing K1 extension sequences, the Index1-th characterizing the first index value; the transmitter using part of the bits of the bit sequence B and a bit sequence B0 as a bit sequence B2, and transmitting, over the Index2-th sub-resource pool of a second time frequency resource region containing K2 sub-resource pools, transmission signals generated on the basis of the bit sequence B2; the Index2-th characterizing a second index value; the first index value Index1 and the second index value Index2 both being determined according to the bit sequence B0.
