METHOD AND APPARATUS FOR COMPRESSION-BASED CSI REPORTING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17812136 titled 'METHOD AND APPARATUS FOR COMPRESSION-BASED CSI REPORTING

Simplified Explanation

The abstract describes a method for operating a user equipment (UE) in a communication system. The method involves receiving a configuration related to a Channel State Information (CSI) report, which includes information about a codebook. The codebook consists of three sets of basis vectors, each set having vectors of different lengths for different types of communication modes. The codebook also includes coefficients associated with each basis vector triple.

  • The method involves receiving a configuration related to a CSI report in a communication system.
  • The configuration includes information about a codebook consisting of three sets of basis vectors.
  • The first set of vectors is for a Single-User (SD) mode, the second set is for a Frequency-Division (FD) mode, and the third set is for a Dual-User (DD) mode.
  • The codebook also includes coefficients associated with each basis vector triple.
  • Based on the configuration, the method determines the components of the codebook.
  • The method then transmits the CSI report, which includes indicators for the basis vectors and coefficients.

Potential applications of this technology:

  • This method can be applied in wireless communication systems, such as 5G networks, to improve the efficiency and reliability of communication between user equipment and base stations.
  • It can be used in various applications that require accurate and timely Channel State Information, such as beamforming, interference management, and resource allocation.

Problems solved by this technology:

  • The method provides a systematic approach for configuring and transmitting CSI reports, which helps in optimizing the performance of the communication system.
  • It addresses the challenge of efficiently representing and transmitting CSI information for different communication modes.

Benefits of this technology:

  • By using different sets of basis vectors and coefficients, the method allows for accurate representation of the channel state in different communication modes, leading to improved system performance.
  • The method provides flexibility in configuring and adapting the CSI reports based on the specific requirements of the communication system.
  • It enables efficient utilization of system resources by transmitting only the necessary information in the CSI reports.


Original Abstract Submitted

A method for operating a user equipment (UE) comprises receiving a configuration about a CSI report, the configuration including information about a codebook, the codebook comprising components: (i) sets of basis vectors including a first set of vectors each of length P×1 for a SD, a second set of vectors each of length N×1 for a FD, and a third set of vectors each of length N×1 for a DD, and (ii) coefficients associated with each basis vector triple (a,b,c), afrom the first set, bfrom the second set, and cfrom the third set; determining, based on the configuration, the components; and transmitting the CSI report including: at least one basis vector indicator indicating all or a portion of the sets of basis vectors, and at least one coefficient indicator indicating all or a portion of the coefficients.
