Abstract: This disclosure provides methods, components, devices and systems for ambient power downlink bandwidth control. Some aspects more specifically relate to waveform generation and sequence selection for transmission of wireless signaling. In some examples, an access point (AP) may generate a spreading waveform by concatenating a sequence of symbols having a first duration and modulating an on-off keying (OOK) waveform having a different symbol duration with the spreading waveform. The AP may apply randomization to each OFDM and may select a sequence of tones in the frequency domain to reduce inconsistent power transmissions across slices of each OFDM symbol. The AP may select which tones to populate and which values to apply to the selected tones such that an amount of variation in transmit power across slices of each OFDM symbol of the waveform is decreased.

Abstract: This disclosure provides methods, devices and systems for generating enhanced trigger frames. Some implementations more specifically relate to trigger frame designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard.
