Zusammenfassung:Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reader device may transmit a delta message that indicates a frequency difference between a data tone frequency for the reader device and a helper tone frequency. The reader device may transmit a data tone signal at the data tone frequency and a helper tone signal at the helper tone frequency. The helper tone signal may be a waveform that is shared among multiple reader devices. Numerous other aspects are described.
