ENHANCED CHANNEL SOUNDING PROTOCOLS FOR WLAN SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240275445 titled 'ENHANCED CHANNEL SOUNDING PROTOCOLS FOR WLAN SYSTEMS
The patent application discusses methods and apparatuses for multi-AP channel sounding for wireless area networks (WLAN).
- The method involves a beamformee receiving an NDP announcement frame and an NDP frame from a beamformer.
- The beamformee also receives an enhanced beamforming request poll trigger frame with feedback format indication.
- Based on the received frames, the beamformee transmits a feedback frame to the beamformer using the indicated format.
- The feedback frame may contain a beamforming report or a vector index feedback report.
- The beamformer is an access point (AP) and the beamformee is a station (STA).
Potential Applications: - Improving wireless network performance and reliability. - Enhancing beamforming capabilities in WLAN systems.
Problems Solved: - Efficient channel sounding in multi-AP environments. - Optimizing feedback transmission for beamforming.
Benefits: - Enhanced network throughput and coverage. - Improved signal quality and reliability in WLANs.
Commercial Applications: Title: Advanced Beamforming Technology for Wireless Networks This technology can be utilized in: - Smart homes and IoT devices. - Enterprise wireless networks. - Public Wi-Fi hotspots and venues.
Questions about Multi-AP Channel Sounding: 1. How does multi-AP channel sounding improve wireless network performance?
- Multi-AP channel sounding allows for better beamforming and feedback transmission, leading to enhanced signal quality and coverage.
2. What are the key differences between a beamformer and a beamformee in a WLAN system?
- A beamformer is typically an access point that coordinates beamforming operations, while a beamformee is a client device that receives beamformed signals.
Original Abstract Submitted
methods and apparatuses for multi-ap channel sounding for wireless area networks (wlan) are disclosed. a method performed by a beamformee may compromise: receiving, from a beamformer, a null data packed (ndp) announcement frame (ndpa); receiving, from the beamformer, an ndp frame; receiving, from the beamformer, an enhanced beamforming request poll (bfrp) trigger frame including an indication of a feedback format; and transmitting, to the beamformer based on the ndp and ndpa, using a format indicated by the feedback format of the bfrp trigger frame, a feedback frame including a feedback report. the trigger frame may be an enhanced beamforming report poll (bfrp) trigger frame. the feedback report may be a beamforming report or a vector index (vi) feedback report. the beamformer may be an access point (ap) and the beamformee may be a station (sta).
