DISTRIBUTED RESOURCE UNIT SIGNALING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17390850 titled 'DISTRIBUTED RESOURCE UNIT SIGNALING
Simplified Explanation
This disclosure presents methods, devices, and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Specifically, it focuses on signaling in a trigger frame to support distributed transmissions via distributed resource units (dRUs).
- An access point (AP) transmits a trigger frame to a wireless station (STA) to solicit a trigger-based (TB) physical layer convergence protocol (PLCP) protocol data unit (PPDU).
- The trigger frame carries RU allocation information, identifying a dRU allocated for the STA.
- The trigger frame also carries tone mapping information, indicating a selected spreading bandwidth design for the wireless channel or subchannel.
- The AP supports channel puncturing by selecting a spreading bandwidth design that controls how dRUs are mapped to non-contiguous tones spanning respective spreading bandwidths.
Potential Applications
- Wireless communication systems
- Cellular networks
- Internet of Things (IoT) devices
- Wi-Fi networks
Problems Solved
- Increasing transmit power of wireless communication devices operating on PSD-limited wireless channels

- Optimal spreading bandwidth design for improved channel utilization
Original Abstract Submitted
This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to signaling in a trigger frame to support distributed transmissions via distributed resource units (dRUs). In some implementations, an access point (AP) may transmit a trigger frame soliciting a trigger-based (TB) physical layer convergence protocol (PLCP) protocol data unit (PPDU) from a wireless station (STA), where the trigger frame carries RU allocation information identifying a distributed resource unit (dRU) allocated for the STA and carries tone mapping information indicating a selected spreading bandwidth design for the wireless channel or subchannel. The AP can support channel puncturing by selecting a particular spreading bandwidth design that controls how dRUs are mapped to non-contiguous tones spanning respective spreading bandwidths.
