Notes/Equations
- This model is used to implement fixed-rate data source for measurement channels. Random data of one transport block is output each transport time interval (TTI); at the same time, the value of current transport format (TF) and maximum transport format (TFMax) are output based on the TTI setting. The number of output tokens is listed in the the following table.

Within one TTI, the current transport format and valid length of output data are determined according to the following table. Within one transport block, output 0 or 1 randomly and TF and TFMax, respectively.
