DISTRIBUTED MULTI-USER (MU) WIRELESS COMMUNICATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240022286 titled 'DISTRIBUTED MULTI-USER (MU) WIRELESS COMMUNICATION
Simplified Explanation
The patent application describes a system and method for group formation and sounding for distributed multi-user multiple input multiple output (MU-MIMO) in wireless communication. The innovation includes the use of announcement frames and beamforming procedures to enable distributed transmission from multiple access points.
- The method involves transmitting an announcement frame from a first access point to initiate a beamforming procedure for distributed transmission.
- The announcement frame includes identifiers of user terminals in different basic service sets.
- A packet is transmitted to measure the channel, and feedback information is received from the user terminal based on the packet.
- The distributed transmission is then performed using the beamforming procedure.
Potential applications of this technology:
- Wireless communication systems
- Multi-user multiple input multiple output (MU-MIMO) systems
- Distributed transmission in wireless networks
Problems solved by this technology:
- Efficient group formation and sounding for distributed MU-MIMO
- Improved channel measurement and feedback in wireless communication
Benefits of this technology:
- Increased capacity and throughput in wireless networks
- Enhanced performance and reliability of MU-MIMO systems
- Improved channel estimation and beamforming accuracy
Original Abstract Submitted
this disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for group formation and sounding for distributed multi-user multiple input multiple output (mu-mimo). some implementations include a method of wireless communication. the method includes transmitting, from a first access point of a plurality of access points, an announcement frame for performing a beamforming procedure for a distributed transmission. the distributed transmission includes a transmission from the plurality of access points. the announcement frame includes at least one identifier of a user terminal in a different basic service set than a basic service set of the first access point. the method further includes transmitting a packet for measuring a channel. the method further includes receiving feedback information from the user terminal based on the packet for measuring the channel. the method further includes transmitting the distributed transmission using the beamforming procedure.
