RESOURCE UNIT (RU) DOWNSIZING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18316543 titled 'RESOURCE UNIT (RU) DOWNSIZING

Simplified Explanation

This patent application discloses methods, devices, and systems for soliciting trigger-based physical layer protocol convergence protocol (PLCP) protocol data units (PPDUs). The focus is on trigger frame and PPDU designs that support RU downsizing. Here are the key points:

  • The disclosure provides methods, devices, and systems for soliciting trigger-based physical layer protocol convergence protocol (PLCP) protocol data units (PPDUs).
  • The trigger frame carries RU allocation information indicating the allocated RU or MRU and downsizing information indicating whether downsizing of the RU or MRU is permitted.
  • If interference is detected in a portion of the wireless medium and downsizing is permitted, the wireless station (STA) transmits the TB PPDU on a downsized RU or MRU.
  • The downsized RU or MRU includes a subset of the tones in the allocated RU or MRU.

Potential applications of this technology:

  • Wireless communication systems
  • Internet of Things (IoT) devices
  • Mobile devices
  • Wi-Fi networks

Problems solved by this technology:

  • Interference in wireless communication systems
  • Efficient utilization of the wireless medium
  • Improved reliability and performance of wireless networks

Benefits of this technology:

  • Enhanced communication reliability in the presence of interference
  • Improved efficiency in utilizing the wireless medium
  • Flexibility in adapting to changing network conditions


Original Abstract Submitted

This disclosure provides methods, devices and systems for soliciting trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data units (PPDUs). Some implementations more specifically relate to trigger frame and PPDU designs that support RU downsizing. For example, an access point (AP) may transmit a trigger frame soliciting a TB PPDU from a wireless station (STA). In some aspects, the trigger frame may carry RU allocation information indicating the allocated RU or MRU (associated with a wireless medium) and downsizing information indicating whether downsizing of the RU or MRU is permitted. If interference is detected in a portion of the wireless medium, and downsizing is permitted, the STA may transmit the TB PPDU on a downsized RU or MRU. The downsized RU or MRU includes a subset of the tones in the RU or MRU allocated by the trigger frame.
