Voice over Internet Protocol (VoIP) transfer is provided over radio links between mobile stations and base stations with a mechanism to schedule initial transmission within voice spurts when semi-persistent allocation of radio resources is employed. The radio link is changed during the voice spurt by allocating different physical resource blocks or by changing transmission parameters with given rescheduling intervals. The scheduling is informed from the base station to involved MS by using data link layer VoIP packet padding bits. The radio link can also be changed per initiative of the MS so that the MS codes a predetermined request into data link layer padding bits of an uplink VoIP packet. The requests from the MS typically involve a change of audio coding mode or informing of the present packet buffer status for VoIP packets at the MS.

The invention relates to a method and a system for improving the quality of a radio signal, particularly for systems according to the IEEE 802.16 standard. In the case of a wireless transmission of radio signals the signals often doesn't reach the receiver in a direct way, but are scattered and reflected at various objects. This leads to the reception of multipath signals with different phases and amplitudes which interfere and decrease the signal quality. In addition, signals from external sources reach the receiver and interfere with the radio signal. It is suggested that the receiver analyses incoming signals and determines whether the additional signal is a multipath signal or stems from an external source. In the first case a constructive interference of the radio signal with the additional signal is arranged. In the second case the additional signal is subtracted from the radio signal. The approach improves the signal-to-noise-ratio as well as the signal-to-interference-ratio and enables the use of a particularly short cyclic prefix in the case of of OFDM signals as well as the use of particularly efficient modulation schemes.
