Title: WAVEFORM CODING WITH MODULATION FOR SINGLE -USER AND MULTIPLE-USER TRANSMISSIONS
Abstract:
A wireless transmit/receive unit (WTRU) may be configured to perform wake up radio (WUR) for one or more WUR receivers. For example, the WTRU may transmit a common preamble to a first WUR receiver using a first frequency range. The WTRU may transmit a first WUR packet to the WUR receiver, after the common preamble. The WTRU may transmit the common preamble to a second WUR receiver using a second frequency range. The WTRU may transmit a second WUR packet after the common preamble, The bandwidth associated with the second WUR packet and the bandwidth associated with the first WUR packet may be smaller than the bandwidth associated with the common preamble, which may avoid interference from other transmitters {e.g., 802.11 transmitters, 802.11 stations, and 802.11 radios). The bandwidth associated with the first WUR packet and the bandwidth associated with the second WUR packet may not be coextensive with one another.
