Dissatisfied with the performance of using manipulated OFDM waveforms solely, the hybrid waveform concept in which a plurality of currently available waveforms are used within a uniting frame structure to better satisfy various needs simultaneously is introduced. Waveform multiplexing approaches for hybrid waveforms are presented. Emerging solutions regarding determining a number of active numerologies, selection of active numerologies and scheduling of users to and within numerologies as part of the system conditions are discussed.eninfo:eu-repo/semantics/embargoedAccessHybrid WaveformsFlexibilityElectrical and ElectronicsBook Chapter9299142N/AN/A
