Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by an apparatus. Certain techniques include sending an indication that the apparatus is capable of supporting lattice reduction (LR) demodulation; receiving a first LR transformation matrix (to be used for demodulating a modulated signal); and receiving the modulated signal.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device or a receiving device may indicate support for crest factor reduction (CFR) techniques using clipping and mirroring. The transmitting device may indicate a clipping level and a mirroring level for a CFR function. The transmitting device may generate a waveform in accordance with the CFR function and may transmit the waveform to the receiving device. The receiving device may monitor the waveform to detect one or more mirrored portions of the waveform. The receiving device may invert the one or more mirrored portions of the waveform over the mirroring level to restore and decode the waveform.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting device may generate a waveform having an original amplitude. The transmitting device may reduce a peak portion of the original amplitude that is above a mirror level according to a reduction function that is based at least in part on a difference function associated with a difference between the mirror level and the peak portion, to obtain a reduced peak amplitude for the waveform. The transmitting device may transmit the waveform with the reduced peak amplitude. Numerous other aspects are described.
