DECODING CHANNEL STATE INFORMATION REPORT PART TWO - A simplified explanation of the abstract

This abstract first appeared for US patent application 18249798 titled 'DECODING CHANNEL STATE INFORMATION REPORT PART TWO

Simplified Explanation

The patent application describes a method for decoding a channel state information (CSI) report in a network node. Here are the key points:

  • The method involves generating a scrambling sequence for a physical uplink shared channel (PUSCH).
  • The PUSCH is descrambled using the generated scrambling sequence.
  • A CSI report part one is decoded to determine a rank indicator.
  • The location of a CSI report part two is determined.
  • A scrambling sequence is extracted from the PUSCH scrambling sequence corresponding to the location of the CSI report part two.
  • A CSI part two scrambling sequence is generated based on the extracted scrambling sequence and the location of the CSI report part two.
  • The extracted scrambling sequence is applied to the location of the CSI report part two.
  • The location of the CSI report part two in the PUSCH is descrambled using the CSI part two scrambling sequence.
  • The CSI part two is then decoded.

Potential applications of this technology:

  • This method can be used in wireless communication systems to improve the decoding of channel state information reports.
  • It can be applied in 5G networks or future generations of wireless networks to enhance the accuracy and reliability of CSI reporting.

Problems solved by this technology:

  • The method addresses the challenge of accurately decoding CSI reports in wireless communication systems.
  • It helps in extracting and decoding different parts of the CSI report, improving the overall quality of the received information.

Benefits of this technology:

  • By improving the decoding process, this method can enhance the performance of wireless networks.
  • It can lead to better resource allocation, interference management, and overall system efficiency.
  • The accurate decoding of CSI reports can enable more effective beamforming and adaptive modulation techniques.


Original Abstract Submitted

According to some embodiments, a method performed by a network node for decoding a channel state information (CSI) report comprises generating a physical uplink shared channel (PUSCH) scrambling sequence, descrambling a PUSCH using the PUSCH scrambling sequence, decoding a CSI report part one to determine a rank indicator, and determining a location of a CSI report part two. The method further comprises extracting a scrambling sequence from the PUSCH scrambling sequence corresponding to the location of the CSI report part two, generating a CSI part two scrambling sequence based on the PUSCH scrambling sequence and the location of the CSI report part two, and applying the extracted scrambling sequence to the location of the CSI report part two. The method further comprises descrambling the location of the CSI report part two in the PUSCH using the CSI part two scrambling sequence and decoding the CSI part two.
