METHOD AND DEVICE FOR RECEIVING FEEDBACK FRAME IN WIRELESS LAN SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240030966 titled 'METHOD AND DEVICE FOR RECEIVING FEEDBACK FRAME IN WIRELESS LAN SYSTEM

Simplified Explanation

The proposed patent application describes a method and device for receiving a feedback frame in a wireless LAN system, specifically for MIMO beamforming. The feedback frame is received by a beamformer from a beamformee and then decoded. The feedback frame includes a first feedback tone for a preset frequency band.

  • The first feedback tone's tone index is set differently based on the preset frequency band and the value of "ng" (which represents the number of guard tones).
  • When the preset frequency band is the 20 MHz band and ng is 8, the tone index of the first feedback tone is set to [-122, -116:8:-4, -2, 2, 4:8:116, 122].
  • When the preset frequency band is the 20 MHz band and ng is 32, the tone index of the first feedback tone is set to [-122, -116, -108:32:-12, -4, -2, 2, 4, 12:32:108, 116, 122].
  • When the preset frequency band is the 40 MHz band and ng is 8, the tone index of the first feedback tone is set to [-244:8:-4, 4:8:244].
  • When the preset frequency band is the 40 MHz band and ng is 32, the tone index of the first feedback tone is set to [-244, -236:32:-12, -4, 4, 12:32:236, 244].

Potential applications of this technology:

  • Wireless LAN systems that utilize MIMO beamforming can benefit from this method and device for receiving feedback frames.
  • It can be applied in various industries where wireless communication is crucial, such as telecommunications, IoT, and smart home devices.

Problems solved by this technology:

  • The method and device provide an efficient way to receive and decode feedback frames in a wireless LAN system, specifically for MIMO beamforming.
  • It ensures accurate reception and decoding of feedback frames, improving the overall performance and reliability of the wireless LAN system.

Benefits of this technology:

  • Improved signal reception and decoding accuracy in wireless LAN systems using MIMO beamforming.
  • Enhanced performance and reliability of wireless communication.
  • Enables better optimization of wireless network resources.
  • Can lead to improved data transmission rates and reduced interference in wireless LAN systems.


Original Abstract Submitted

proposed are a method and device for receiving a feedback frame in a wireless lan system. specifically, a beamformer receives a feedback frame for mimo beamforming from a beamformee and decodes the feedback frame. the feedback frame includes a first feedback tone for a preset frequency band. when the preset frequency band is the 20 mhz band, the tone index of the first feedback tone is set to [−122, −116:8:−4, −2, 2, 4:8:116, 122] when ng is 8, and [−122, −116, −108:32:−12, −4, −2, 2, 4, 12:32:108, 116, 122] when ng is 32. when the preset frequency band is the 40 mhz band, the tone index of the first feedback tone is set to [−244:8:−4, 4:8:244] when ng is 8, and [−244, −236:32:−12, −4, 4, 12:32:236, 244] when ng is 32.
