Notes/Equations
- This subnetwork model is used to provide fully coded source of an uplink 2048 kbps reference measurement channel that is defined in [1]. The schematic for this subnetwork, shown in the following figure, is the same as for other uplink reference measurement channels.

- DTCH and DCCH data are generated by transport channel source model 3GPPFDD_TrCHSrc. After channel coding (illustrated in the following figure) the dedicated physical data channel and dedicated physical control channel are spread and scrambled by 3GPPFDD_ULSpread. The scramble code is determined by the ScrambleCode and ScrambleType parameters. The amplitude of complex output is normalized to 1. Reference DCCH and DTCH are output from the original transport channel source.
A group of parameters of data pattern are used to determine the contents of DCCH and DTCH, and data filled in TPC and FBI fields. The DPCCH_SltFmt value determines the DPCCH slot format.
Please note, some numbers listed in Annex A.6 of [1] are different than those used in the following figure. The Turbo coding input size must be 164505; therefore, the Turbo coding output is 493911. The DTCH radio frame size must be 61739; consequently the puncturing rate must be 7% instead of 1%. These numbers are corrected in [2].
