Notes/Equations
  1. This model implements uplink second de-interleaving. Please refer to [1] for uplink second interleaving processing.
  2. This model fires once per radio frame. Each firing, this model receives data blocks of each physical channel at multiple input pin DataIn, and receives slot format and physical channel number at pins SltFin and PCNin. This model then de-interleaves the data blocks of each physical channel.
  3. This model requires the information of all transport channels in the form of arrays.
    The DynTFSetArray 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.
    When setting TTIArray, CRCArray and CHCodingTypeArray values, refer to the following table.
    Settings for TTIArray, CRCArray and CHCodingTypeArray Values
    TTIArray CRCArray CHCodingTypeArray
    Time Value Coding Value Coding Value
    10ms 0 No CRC 0 No Coding 0
    20ms 1 8 bits 1 1/2 CC 1
    40ms 2 12 bits 2 1/3 CC 2
    80ms 3 16 bits 3 1/3 TC 3
        24 bits 4    
    CC = convolutional coding; TC = turbo coding
  4. The length of most parameters in the form of arrays is equal to the value of parameter TrCHNum, each element of an array represents a certain transport channel.
    The DynTFSetArray array is variable and used to provide all possible transport block size and transport block set size for each transport channel. Another parameter TFSetSizeArray is used to indicate how many pairs of transport block size and transport block set size are contained in a certain transport channel. For example, TFSetSizeArray = "3 2" means the first three pairs of transport block size and transport block set size belong to the first transport channel, and the next two pairs belong to the second transport channel.
