摘要： 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.

摘要： An apparatus for wireless communication at a UE is provided. The apparatus is configured to receive one or more pilot signals superimposed on a data signal from a network entity. The apparatus is further configured to receive an indication of a first set of locations in at least one of time or frequency from the network entity. The data signal or the scrambled data signal is near orthogonal to a channel estimation filter of the transmission channel between the network entity and the UE at the first set of locations. The apparatus is further configured to transmit characteristics of the transmission channel to the network entity. The characteristics of the transmission channel is determined based at least in part on the first set of locations.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive data encoded based on a multi-level balanced code, codewords of the multi-level balanced code being selected based on a finite number of multiple sum values, corresponding to all constellation symbol sequences in the multi-level balanced code. The UE may receive a superimposed pilot (SIP) using communication resources occupied by the data. The UE may estimate one or more channel parameters based on the SIP and the multi-level balanced code. Numerous other aspects are described.
