APPARATUS AND METHOD OF UPLINK BEAMFORMING IN WIRELESS LOCAL AREA NETWORK SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18224426 titled 'APPARATUS AND METHOD OF UPLINK BEAMFORMING IN WIRELESS LOCAL AREA NETWORK SYSTEM
Simplified Explanation
The patent application describes an operating method for wireless communication between two devices in a local area network. Here is a simplified explanation of the abstract:
- The first device receives a data unit from the second device, which includes a payload containing a trigger frame.
- Based on a value in the preamble of the data unit, the first device prepares an uplink beamforming matrix.
- The first device then uses the uplink beamforming matrix to beamform the data unit.
- Finally, the first device transmits the beamformed data unit to the second device, based on a value in the trigger frame.
Potential Applications:
- Wireless local area networks (WLANs)
- Communication between devices in a network
Problems Solved:
- Efficient and reliable wireless communication between devices
- Optimizing beamforming for improved signal quality
Benefits:
- Enhanced wireless communication performance
- Improved signal strength and reliability
- Increased network capacity and efficiency
Original Abstract Submitted
An operating method of a first device communicating with a second device in a wireless local area network (WLAN), includes: receiving, from the second device, a physical layer protocol data unit (PPDU) including a payload that includes a trigger frame; preparing an uplink beamforming matrix based on a value of an uplink beamforming-related first sub-field included in a preamble of the PPDU; beamforming, according to the uplink beamforming matrix, the PPDU; and transmitting the beamformed PPDU to the second device based on a value of an uplink beamforming-related second sub-field included in the trigger frame.
