Abstract
Methods, systems, and devices for wireless communications are described that provide for application of a tone reservation signal for orthogonal time-frequency space (OTFS) waveform communications. A tone reservation signal may use a first subset of resources of a set of resources associated with an OTFS frame, which may mitigate relatively large PAPR associated with transmission of the OTFS frame. A tone reservation signal may use in-frame resources (e.g., as delay-Doppler locations within a delay-Doppler resource grid) of the OTFS frame, or may use tone reservation resources may correspond subcarriers that are out-of-band with subcarriers of an OTFS frame. Signaling may be provided by a transmitting device that indicates the tone reservation resources, and a receiving device may decode a received communication in accordance with remaining resources other than the tone reservation resources.
