The chart shows the data as below:

RRC State: RRC State, one of {CELL_DCH, CELL_FACH, CELL_PCH, URA_PCH, Idle}.

SIR: Signal-to-Interference Ratio. This attribute gives the DPCH Signal to Interference Ratio value, as measured by the UE. The unit is dB.

UE TxPower: UE Transmit Power. This attribute gives value of the transmitted power by the UE, averaged over a certain time. The unit is dBm.

Power Ctrl Alg: Power Control Algorithm:  3GPP 25.331

Tx Command UL: Transmit Power Control on uplink over the last 0.5 seconds: percentage of power control commands that were “increase”commands. This attribute gives the ratio between "up" and "down" TPC commands sent by the NB to the UE. If the attribute is more than 50%, it means that the UE received more "ups" than "downs".

Tx Command DL: Transmit Power Control on downlink over the last 0.5 seconds: percentage of power control commands that were “increase”commands. This attribute gives the ratio between "up" and "down" TPC commands sent by the UE to the NB. If the attribute is more than 50%, it means that the UE sent more "ups" than "downs".

Speech Codec DL/UL: Voice codec and codec rate.{4.75kb, 5.15kb, 5.90kb, 6.70kb, 7.40kb, 7.95kb, 10.2kb, 12.2kb, 6.60kb, 8.85kb, 12.65kb, 14.25kb, 15.85kb, 18.25kb, 19.85kb, 23.05kb, 23.85kb}

Speech Quality DL/UL: AMR Speech Quality Indicator {Speech Good, Speech Degraded, Onset, SID First, SID Update, SID bad, Null Data.}
