1. A method of exporting a smoothed transport block size to control an operation of an application, comprising: obtaining, by one or more processors of at least one network node, historical time series data, the historical time series data including historical transport block size information, historical modulation and coding scheme information and historical physical resource block utilization information; predicting, by the one or more processors, future value information based on the historical time series data, the future value information including modulation and coding scheme future values and physical resource block future values; producing, by the one or more processors, a mapping function regressing first input data to first output data, the first input data including the historical modulation and coding scheme information and the historical physical resource block utilization information, the first output data including the historical transport block size information; forecasting, by the one or more processors, a smoothed transport block size by inputting the future value information into the mapping function; and exporting, by the one or more processors, the smoothed transport block size to a network node to control an operation of an application.
