Abstract
Aspects of the disclosure relate to synchronization signaling supporting multiple waveforms. A synchronization signal block (SSB) is configurable for transmission using either at least a first waveform or a second waveform, where the first waveform has higher peak to average power ratio (PAPR) characteristics such as OFDM and the second waveform has lower PAPR characteristics, such as DFT-S-OFDM. The SSB is transmitted selectively using either the first waveform or the second waveform for transmission of the SSB. Furthermore, the characteristics of the transmission such as a predetermined pattern of the first and second waveform transmissions may be utilized to communicate to a receiver the type of waveform being used. In this manner, SSB transmissions may take advantage of respective advantages afforded by each type of waveform, particularly when using higher frequency transmissions above 40 GHz in wireless communication systems.
