UMTS Simulations (Monte-Carlo)

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 Æ (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 required to satisfy the uplink Eb/Nt requirement. The mobile is rejected if the calculated required transmit power is higher than the maximum mobile transmit power Æ (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 Æ (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 Æ (UL load saturation) - Total downlink power higher than the maximum total downlink power Æ (DL load saturation) - Number of OVSF codes insufficient Æ (Code saturation) - Number of channel elements available insufficient Æ (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.
