Title: DATA TRANSMISSION METHOD AND DEVICE
Abstract:
Disclosed are a data transmission method and device, used for solving the problem, which no relevant solution of the prior art solves, of collision when using uplink channels having different transmission time interval (TTI) lengths for transmission in the same time unit. The method is: determining the presence in a time unit i of a first uplink channel using a first TTI length for transmission and a second uplink channel using a second TTI length for transmission, said first uplink channel and said second uplink channel overlapping in time; obtaining a time node of the second uplink channel determined to be present in said time unit i; and/or obtaining the position of the overlapping symbols of the second uplink channel and the first uplink channel in the time unit i; on the basis of the time node and/or the position of overlap of the symbols, determining the uplink channel needing to transmit in the time unit i and performing transmission.
