The device may transmit the WUS waveform via at least a portion of a WUS bandwidth and a portion of a WUS time duration. The WUS waveform may occupy at least the portion of the WUS bandwidth and at least the portion of the WUS time duration in accordance with a pattern that is based on the modulated set of information bits."
The patent application was internationally filed on May 11, 2023, under International application No.PCT/CN2023/093456.
