Notes/Equations
  1. This model is used to allocate transmission power to parallel channels in multi-code transmission.
  2. In multi-code transmissions, pilot, transport format combination information and TPC symbols can be inserted in the first code channel only. (Other code channels do not have pilot, information and TPC symbols.)
    Power allocation for multi-code transmission is determined as

    PP = N × Pd

    where

    PP denotes proportional power of the pilot, transport format combination information and TPC symbols in the first code channel
    Pd denotes the proportional power of the encoded data.
    N is the number of code channels

    The correspondence between physical channel type and numbers of pilot, TPC, TFCI symbol and data are presented in the following table.
