Notes/Equations
  1. This model is used to implement physical channel mapping. The PhCH for uplink and downlink is defined in [2]. The bits input to the physical channel mapping are denoted by vp 1, vp 2, ..., vpU where p is the PhCH number and U is the number of bits in one radio frame for one PhCH. The bits vpk are mapped to the PhCHs so that the bits for each PhCH are transmitted over the air in ascending order with respect to k.
    In uplink, the PhCHs used during a radio frame are either completely filled with bits that are transmitted over the air or not used at all. The only exception is when the UE is in compressed mode; the transmission can then be turned off during consecutive slots of the radio frame.
  2. This model fires once per radio frame.
    Each firing, this model receives data blocks of all physical channels at a pin DataIn, then maps those data blocks onto each physical channel.
    DataOut will output data of one radio frame, and next model will input data block of one slot. This means the next model will fire 15 times when this model fires once.
