Abstract

A technique for estimating the quality of an unmeasureable channel in a time division multiple access radio telecommunication network is disclosed. In an embodiment of the invention, the estimate of the unmeasurable channel is based on samples from other time slots or channels on the same carrier frequency in the same cell. By way of example, a plurality of quality measurements, which may include the interference, bit error rate (BER), frame erasure rate (FER), and burst quality (BQ) are performed on associated channels of the same carrier frequency and cell as the unmeasurable channel. The quality is based on the suitable maximum value of the estimated values derived from the associated channels. The method is applicable to either uplink or downlink signal measuring techniques and provides an effective means for estimating intrafrequency channels that are closely correlated.
