When an OFDM radio system which uses a wide frequency band is interfered with by another narrow-band radio system, the interference can frequently be compensated but the transmission quality decreases drastically. Thus, narrow-band interferers in an OFDM radio system are determined according to the invention whereby none of the subscribers of the radio system transmits in a defined time slot or scan slot but all switch at the same time into the receiving mode. If there is interference (P1, P2), it is detected in this time slot. Countermeasures are taken individually in all the mobile devices, in particular the detection of the frequency and strength of the narrowband interference (P1, P2) and the configuration of a flexible notch filter (140) in the time range to the detected frequency and strength. The scanned received signal (RXS) is then filtered in the time range, i.e. before the FFT (120) and the OFDM channel estimation (130) by the correspondingly configured notch filter (140). The notch (S1, S2) of the notch filter thereby acts in the transmission function like a natural break when receiving data.

A method to perform beam management (BM) and / or synchronization (Sync) using primary synchronization signal (PSS) when pilot contamination is low to improve system performance is proposed. A UE first determines pilot contamination level on PSS of a synchronization signal block (SSB), depending on different network deployment scenarios.

Otherwise, if the pilot contamination level is low, then the UE follows a 4-symbol mode, e.g., uses PSS as an extra symbol for BM or Sync to improve system performance.
