<p>For determining the transmission quality of a radio channel (DPDCH) it is well known to estimate measures such as the so-called signal-to-interference ratio, the so-called frame error rate or the so-called bit error rate (BER). According to the invention it is proposed to take, at the receiving end, from the signaling data (TPC; TFCI) that part (TFCI) of signaling data which are which are encoded and transmitted with the higher redundancy and to compare them (TFCI) with reference data (REF), and to compute on the basis of this comparison a measure (BER) of the transmission quality of the radio channel (DPDCH). Thus, a measure (BER) of the transmission quality is computed on the basis of a small but very reliable set of data. Therefor few processing time and power are needed to accomplish an accurate result. The invention will preferably be applied to radiocommunications systems in which CDMA radio signals are transmitted and which is compatible to the standard UMTS (universal mobile telecommunications system). <IMAGE></p> |
