UMTS Simulations (Monte Carlo)R99 Portion:
1) Best server determination: The best server is determined for each mobile using Ec/Io criterion. The
mobile is rejected if the Ec/Io condition is not satisfied or the uplink load factor is higher than the specified
limit (Ec/Io pilot < Ec/Io min pilot; Admission rejected)
2) Active set determination: The active set is determined for each mobile.
3) Uplink power control: The mobile transmit power is calculated. It corresponds to the power requiredto satisfy the uplink Eb/Nt requirement. The mobile is rejected if the calculated required transmit power is
higher than the maximum mobile transmit power (Pmob >Pmob max)
4) Downlink power control: The transmitter traffic channel power is calculated. It corresponds to the
power required to satisfy the downlink Eb/Nt requirement. The mobile is rejected if the calculated traffic
channel power is higher than the maximum traffic channel power allowed (Ptch > Ptch max)
5) Uplink and downlink interference update: The uplink load factor and total downlink transmit power are
updated with these results.
6) Congestion and radio resource control: Mobiles are rejected if any of the following situations occur:
- Uplink load factor higher than the specified limit
(UL load saturation)- Total downlink power higher than the maximum total downlink power (DL load saturation)
- Number of OVSF codes insufficient (Code saturation)
- Number of channel elements available insufficient (Channel element saturation)
7) Convergence study: The previous iterations are repeated until the simulation converges, i.e. either
the maximum number of iterations is reached or both, uplink and downlink, criteria are verified.
