Notes/Equations
  1. This model decodes the TFCI code word to TFCI information value according to the coding mode illustrated in the following figures.
  2. If the CodingMode parameter is set to Normal, one TFCI value is output; if the CodingMode parameter is set to Split, 2 TFCI values are output.

    Channel Coding of 10 TFCI information Bits

    Channel Coding of 5 TFCI Information Bits
  3. For uplink physical channels (regardless of the SF and downlink physical channels) if SF > 64, the code word is 30 bits. For downlink physical channels with SF < 128, the code word is 120 bits. The length is set by CodeLength parameter.
