CHANNEL STATE FEEDBACK WITH DICTIONARY LEARNING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17817304 titled 'CHANNEL STATE FEEDBACK WITH DICTIONARY LEARNING

Simplified Explanation

The abstract of this patent application describes a wireless communication system where a user equipment (UE) can report channel state information (CSI) using a learned dictionary of sparse vectors. The UE determines this learned dictionary either by receiving a shared dictionary from a similar and nearby UE or by training it based on logged CSI measurements. The UE then indicates the learned dictionary to a serving base station and reports a sparse vector representing the CSI based on the learned dictionary.

  • The UE in a wireless communication system can report CSI using a learned dictionary of sparse vectors.
  • The learned dictionary can be obtained from a similar and nearby UE or trained based on logged CSI measurements.
  • The UE indicates the learned dictionary to a serving base station.
  • The UE measures CSI for multiple channels and reports a sparse vector representing the CSI using the learned dictionary.

Potential applications of this technology:

  • Wireless communication systems that require efficient reporting of channel state information.
  • Systems where user equipment needs to adapt its transmission based on channel conditions.
  • Networks that rely on accurate and timely CSI feedback for optimization and resource allocation.

Problems solved by this technology:

  • Efficient utilization of wireless communication resources by reporting sparse vectors instead of full CSI.
  • Improved accuracy of CSI reporting by using a learned dictionary tailored to the specific UE.
  • Reduced overhead in training and transmitting CSI information.

Benefits of this technology:

  • Enhanced performance and reliability of wireless communication systems.
  • Improved spectral efficiency by optimizing resource allocation based on accurate CSI feedback.
  • Reduced signaling overhead and bandwidth consumption by reporting sparse vectors instead of full CSI.


Original Abstract Submitted

In a wireless communication system, a user equipment (UE) may report channel state information (CSI) using a learned dictionary defining a set of sparse vectors. The UE determines a learned dictionary for CSI reporting. For example, the UE receives a shared dictionary from a similar and nearby UE or the UE trains the learned dictionary based on logged CSI measurements. The UE indicates the learned dictionary to a serving base station. The UE measures CSI for a plurality of channels. The UE reports a sparse vector representing the CSI based on the learned dictionary to the serving base station.
