Reduction of peak to average power ratio exploiting multi-numerology structure

Methods and techniques are described for reducing PAPR in a system with multiple numerologies. The PAPR is reduced by means of minimization of a cost function including PAPR for some predefined parameters. For example, PAPR may be minimized for phase and/or amplitude and/or time/cyclic shift adjustm...

Zusammenfassung:	Methods and techniques are described for reducing PAPR in a system with multiple numerologies. The PAPR is reduced by means of minimization of a cost function including PAPR for some predefined parameters. For example, PAPR may be minimized for phase and/or amplitude and/or time/cyclic shift adjustment to adjust OFDM symbol phase and/or amplitude, or for number and/or type of numerologies to be combined for the transmission.
