Notes/Equations
  1. This model is used to implement uplink radio frame equalization. Radio frame size equalization means the input bit sequence is padded to ensure the output can be segmented in Fi data segments of the same size. Radio frame size equalization is only performed in the UL (DL rate matching output block length is always an integer multiple of Fi).
    The input bit sequence to the radio frame size equalization is denoted by ci 1, ci 2, ci 3, ..., ciEi, where i is TrCH number and Ei is the number of bits. The output bit sequence is denoted by ti 1, ti 2, ti 3, ..., t

    iT, where Ti is the number of bits. The output bit sequence is derived as follows:
    tik = cik for k = 1 ... Ei; and
    tik = {0, 1} for k = Ei + 1 ... Ti, if Ei < Ti


    where

    Ti = F i × Ni; and
    Ni = [Ei/Fi] is the number of bits per segment after size equalization.

  2. This model fires once per TTI. Each firing, one token is consumed by pin SizeIn, this token indicates the effective length of data block input at DataIn. After padding necessary bits, the data block is output at DataOut, and a token is generated by DataOut to indicate the effective length of the output data block.
  3. The DynTFSet parameter requires an integer array. The correct format is transport block size 1, transport block set size 1, transport block size 2, transport block set size 2, etc. The size of this array must be a multiple of 2, and the transport block set size must be a multiple of the relative transport block size.
