Abstract:
This disclosure provides methods, devices and systems for wireless communication, and particularly, methods, devices and systems for physical (PHY) layer control signaling. A first physical layer convergence protocol (PLCP) protocol data unit (PPDU) may precede a second PPDU. The first PPDU may be referred to as a PHY control PPDU and may include a physical layer control signaling field (CNT-SIG) that informs one or more stations (STAs) regarding a physical layer configuration they should use for the second PPDU. The PHY control PPDU may enable dynamic subchannel assignments for one or more identified STAs, legacy STAs, or sub-bandwidth operating devices. The techniques of this disclosure may enable sharing of a wide bandwidth wireless channel by different types of devices or different basic service sets (BSSs) assigned to different subchannels of the wireless channel.
