Abstract: A low density parity check code transmission method and device, for use in improving the anti-burst-error capability of a low density parity check code. The method provided by the present application comprises: an interleaver changes the sequence of bit streams of a low density parity check code according to a preset rule, and outputs to a modulator the low density parity check code the sequence of bit streams of which is changed; the modulator modulates the low density parity check code the sequence of bit streams of which is changed and then sends the modulated low density parity check code to a receive end by using a channel.

Abstract: The present disclosure relates to the field of wireless communication technology, and provides a data transmission method and a data transmission device, so as to solve the problem in the related art where, for 5G application scenarios, in the case that an uplink scheduling algorithm for a conventional 4G system continues to be used, a large number of control signaling overheads are required due to the meteoric growth in the number of UEs to be connected. In the present disclosure, a network side device determines non-orthogonal multiple access basic transmission units allocated to UEs, detects a pilot signal from each UE on the corresponding non-orthogonal multiple access basic transmission unit, and in the case that the pilot signal has been detected, performs data detection on the UE which has transmitted the pilot signal through the non-orthogonal multiple access basic transmission unit.
