Notes/Equations
- This model is used to segment one transport channel data block in TTI into the number of radio frames determined by TTI. Each radio frame has the same number of bits.
Each firing, for Downlink, Mp × Np × T tokens of out and T tokens of outSize are produced when Mp × Np × T tokens of in and one token of inSize are consumed; for Uplink, Mt × T tokens of out and T tokens of outSize are produced when Mt × T tokens of in and one token of inSize are consumed. Refer to the following tables for the values of T, Mp, and Mt. - DL_PhyCHType and DL_PhyCHNum are valid only when LinkDir = Downlink; UL_DCHType is valid only when LinkDir = Uplink.
- When the transmission time interval is longer than 10 ms, the input bit sequence in TTI is segmented and mapped onto T consecutive radio frames. Mp × Np × T tokens (for downlink) or Mt × T (for uplink) of input data are bit sequence in TTI, corresponding to T frames data. In variable rate transmission, only inSize tokens in the input tokens are useful. This model equally segments inSize tokens to T frames. In each frame, outSize tokens are useful.
