METHOD AND WIRELESS NETWORK FOR MANAGING CHANNEL STATE INFORMATION (CSI) FEEDBACK COMPRESSION IN WIRELESS NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18052521 titled 'METHOD AND WIRELESS NETWORK FOR MANAGING CHANNEL STATE INFORMATION (CSI) FEEDBACK COMPRESSION IN WIRELESS NETWORK

Simplified Explanation

The patent application is about a communication system (5G or 6G) that supports a higher data transmission rate. It discloses methods for managing Channel State Information (CSI) feedback compression in a wireless network by a base station.

  • The method involves transmitting pilot symbols over a specific time period called the first window.
  • The base station receives feedback from the user equipment (UE) in the form of two types: first type feedback and second type feedback. This feedback can be received at the end of the first window or after the first window.
  • The base station also receives compressed CSI feedback from the UE during the first window. This compressed feedback is based on predefined precoder weights.
  • The method includes computing and predicting precoder weights for the UE in a second window. These weights are computed for each sub-band of the UE and are based on the feedback received from the UE.
  • The received CSI feedback compression is managed by the base station based on the predicted precoder weight.

Potential applications of this technology:

  • This technology can be applied in 5G or 6G communication systems to support higher data transmission rates.
  • It can be used in wireless networks to improve the efficiency of CSI feedback management.
  • The methods described in the patent application can be implemented by base stations to optimize the transmission and reception of data in a wireless network.

Problems solved by this technology:

  • The technology addresses the challenge of managing CSI feedback compression in a wireless network.
  • It solves the problem of efficiently transmitting and receiving CSI feedback in a communication system.
  • The methods described in the patent application help in predicting and managing precoder weights for improved data transmission.

Benefits of this technology:

  • The technology enables higher data transmission rates in 5G or 6G communication systems.
  • It improves the efficiency of CSI feedback management, leading to better overall network performance.
  • By predicting and managing precoder weights, the technology optimizes data transmission and reception in a wireless network.


Original Abstract Submitted

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods for managing CSI feedback compression in wireless network by base station. The method includes transmitting at least one pilot symbol over first window. The method includes receiving at least one of a first and second type feedback from a UE at an end of the first window or after the first window. The method includes receiving the compressed CSI feedback based on predefined precoder weights in the first window. The method includes computing and predicting at least one precoder weight for the UE in at least one time instant in a second window for at least one sub-band of the UE based on the at least one of the first and second type feedback. The method includes managing the received CSI feedback compression based on the predicted precoder weight.
