Notes/Equations
  1. This subnetwork model measures 3GPP FDD uplink reference channel bit error rate (BER) for DPDCH, DTCH, and DCCH, as well as block error rates (BLER) for DTCH and DCCH. BER is measured by comparing the decoded bits with the reference bits. BLER is measured based on the CRC results.
    The schematic for this subnetwork is shown in the following figure.
  2. FrameNum specifies the number of 10 msec frames to be measured. The DPDCH physical channel is measured based on a 10 msec-frame; DTCH and DCCH are measured based on the transport block set size per each TTI. The frame number that is set based on a 10 msec frame is converted to the TTI number using the ceil function. For example, if frame number is 11 and the TTI is 20 msec, the TTIs to be measured will be ceil(11 × 10 / 20) = 6.
  3. CollectBits specifies whether or not to save the reference and decoded bits.
  4. The transport block set size for each reference measurement channel is pre-defined using equations.
