摘要
The present invention relates to methods and arrangements for interference reduction for bursty or intermitted transmissions. DPCCH gating with regular on/off-gating patterns can create waveforms that can interfere with non-UMTS audio equipments, e.g. hearing aids. The present invention relates to modifying the transmission instants of data packets in such a way such interference can be significantly reduced. This is achieved by introducing a randomization mechanism into the mapping function of data packets onto the HARQ processes, which in turn are mapped onto predefined transmission occasions (sub-frames). This results in a non-periodic transmission pattern while maintaining user data transmission requirements.
