Notes/Equations
- This model is used to implement first de-interleaving. First de-interleaving is a block de-interleaver with inter-column permutations before the rate de-matching in downlink or radio frame de-equalization in uplink.
In the downlink, M × Nd × NTTI tokens of Out and one token of outSize are produced when M × Nd × NTTI tokens of In and one token of inSize are consumed, where NTTI equals 1, 2, 4, or 8 when TTI is 10 ms, 20 ms, 40 ms, or 80 ms, respectively. Refer to the following table for the value of M.Downlink M Values
In the uplink, M tokens of Out and one token of outSize are produced when M tokens of pin In and one token of pin inSize are consumed. Refer to the following table for the value of M.DL_PhyCHType
