Notes/Equations
- This model decodes the TFCI code word to TFCI information value according to the coding mode illustrated in the following figures.
- 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
- 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.
