PRE-ASSOCIATION SOUNDING IN WIRELESS NETWORKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18607064 titled 'PRE-ASSOCIATION SOUNDING IN WIRELESS NETWORKS

Simplified Explanation

This patent application describes devices, systems, methods, and processes for pre-association sounding between a user device and a network device. The user device announces its pre-association sounding capability to the network device, which then transmits sounding frames to the user device. The user device processes these frames, determines channel state information (CSI), and sends it back to the network device before association. This pre-emptive sounding reduces latency overheads associated with sounding.

  • User device announces pre-association sounding capability to network device.
  • Network device transmits sounding frames to user device.
  • User device processes frames, determines CSI, and sends it back to network device.
  • Pre-emptive sounding reduces latency overheads associated with sounding.
  • Exchange of sounding frames and CSI occurs before user device associates with network device.

Pre-association sounding reduces latency overheads and improves beamforming efficiency in wireless communication systems, leading to enhanced performance and faster data transmission.

What are the key steps involved in pre-association sounding between a user device and a network device?

The key steps include the user device announcing its pre-association sounding capability, the network device transmitting sounding frames, the user device processing these frames to determine CSI, and exchanging the CSI with the network device before device association.


Original Abstract Submitted

Devices, systems, methods, and processes for pre-association sounding executed between a user device and a network device are described herein. The user device may announce its pre-association sounding capability to the network device. The network device, also supporting pre-association sounding, may transmit a plurality of sounding frames to the user device. The user device may process the plurality of sounding frames, determine channel state information (CSI), and transmit the CSI to the network device. The plurality of sounding frames and the CSI may be exchanged between the user device and the network device prior to the user device associating with the network device. By the time the user device associates with the network device, the network device may already have the CSI required for beamforming one or more transmissions towards the user device. Thus, latency overheads associated with sounding are reduced by performing pre-emptive sounding while in a pre-association state.
