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.

Claim (Index 28):
The network side device according to  claim 23 , wherein the network side device is further configured to:\n in the case that there is a pilot signal conflict between a UE and the other UEs, schedule the UE to perform the data transmission on a reserved scheduling time-frequency resource, and notify, through downlink signaling, the UE to be mapped to a new non-orthogonal multiple access basic transmission unit; or in the case that there is a pilot signal conflict between a UE and the other UEs, notify the UE that there is a multi-user pilot signal conflict through downlink signaling, so as to enable, in the case that there exists the data transmission, the UE to transmit the pilot signal and data on the corresponding non-orthogonal multiple access basic transmission unit within a subframe delayed by N subframes, where N is a positive integer, wherein the network side device is further configured to determine whether or not there is the pilot signal conflict between the UE and the other UEs through: determining whether or not a time interval for the reception of uplink data from the UE is greater than a threshold; and in the case that the time interval is greater than the threshold, determining that there is the pilot signal conflict between the UE and the other UEs, and otherwise determining that there is no pilot signal conflict between the UE and the other UEs, wherein the network side device is further configured to, after the network side device has detected the pilot signal, perform pilot channel estimation on the UE that has transmitted the pilot signal through the non-orthogonal multiple access basic transmission unit.
