In a mobile telecommunications system, received transport channels are checked for a correct checksum or for a transport format combination indicator (TFCI) and correctness of reception of said channels is declared according to said step of checking. For instance, an operating WCDMA cellular system determines whether the frame reception is correct or if the frame is synchronized by determining whether a CRC checksum is present and correct and, if so, declaring correct reception of the downlink and, if not, determining in the terminal from any transport format combination indicator (TFCI) signal present in the downlink whether a discontinuous transmission (DTX) frame is present or not, and if not, declaring incorrect reception of the downlink, but if so, declaring correct reception of the downlink. Additionally, quality information obtained from the DTX frame can be used in an outer loop power control quality target setting.
