AMR DL Coding Rate adj.th1(F) |
|---|---|
Description |
Based on the RQI in the call measurement report, the BTS and MS automatically adjust the current speech coding rate according to the related algorithm. The coding rate adjustment threshold is the threshold of RQI. The RQI indicates the carrier-to-interference ratio (CIR) of the call. If RQI equals 1, the CIR is 0.5 dB; if RQI equals 2, the CIR is 1 dB; and so forth. Since there are multiple coding rates in the ACS, there is an adjustment threshold and an adjustment hysteresis between the neighboring coding rates. |
