SIR Uplink Signal-to-Interference Ratio (SIR) per radio link set (RL-Set), measured on Dedicated Physical Control Channel (DPCCH) after radio link combination in the Node B. NodeB measures the Pilot Bit power of DPCCH and calculates the Signal-to Interference ratio (SIR) per RL-set. This is compared to SIRtarget and based on the result TPC sent to UE (increase/decrease TxPwr). Range: [-11..20] dB by step of 0.5 dB The optimal value for the SIR is around 3-6 dB. High SIR value indicates the presence high UL Interference. Low SIR triggers PC algorithm to order changing UeTxPwr for higher value -> Increase of UL Interference.SIR ERROR SIRerror = SIR - SIRtarget. SIRerror shows the gap between the assigned SIRtarget and measured SIR. Value of SIRerror per connection shows how well the SRNC is able to adjust UE Tx Pwr, which shows the accuracy of Power Control. SIR should follow the SIRtarget -> SIRerror should present 0 value. SIRerror measured on Dedicated Physical Control Channel (DPCCH) after radio link combination in the Node B and reported for all RL-Sets relating to the UE connections being recorded. Range: [-31..31] dB by step of 0.5 dB (SIRtarget is adjusted by UL outer-loop power control algorithm and used for closed-loop PC. ) TRANSMITTED CODE POWERTransmitted code power is the transmitted power measured on the pilot bits of one channelization code on one scrambling code on one Dedicated Physical Channel (DPCH).One average value is reported for all DPCHs relating to the UE connections.This is the power allocated per connection. Based on this measurementDL load of UE per connection can be estimated.

Range: [-10..46] dBm by step of 0.5 dB The higher TCP value indicates worse RF conditions and higher DL-code Pwr load since pilot channel has to transmit with higher power. DOWNLINK TRANSPORT CHANNEL BLER (BLER = Block Error Rate) BLER is estimation of Transport Channel Block Error Rate in DL DCH, based on evaluating CRC on each Trabsport Block after Radio Link combination. BLER is long-time average block error rate calculated from transport blocks. Range: [01] by setp of 0.065 The lower BLER value indicates better Transport Channel quality. There is NO BLER measurement in HSDPA.To convert the reported Ec/Io and RSCP values use following equations:Ec/Io = -24 dB + (Ec/IoREPORTED / 2)RSCP = -115 dBm + RSCPREPORTEDUE Tx POWER The UE transmitted power is the total power transmitted by the UE on one carrier. UE Tx power measurement is used for power management and handover preparation. Range: [-50..33] dBm by step of 1 dB. The lower the UE Tx power the lower the UL Interference since UE is not ordered by PC algorithm to use high power.
