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

This abstract first appeared for US patent application 18063647 titled 'METHOD AND APPARATUS FOR CSI REPORTING

Simplified Explanation

The abstract describes a method for operating a user equipment (UE) in a wireless communication system. Here are the key points:

  • The method involves receiving configuration information for channel state information (CSI) reporting.
  • The configuration information includes a CSI reporting band and a frequency granularity of CSI reporting.
  • The CSI reporting band is within a bandwidth part (BWP) consisting of a certain number of physical resource blocks (PRBs).
  • The frequency granularity of CSI reporting is determined based on whether the number of PRBs is less than a threshold value.
  • The method identifies the frequency granularity of CSI reporting based on the received configuration information.
  • A CSI report is generated with the identified frequency granularity, which includes information such as precoding matrix indicator (PMI) and channel quality indicator (CQI).
  • The generated CSI report is transmitted over an uplink (UL) channel.

Potential applications of this technology:

  • This method can be applied in various wireless communication systems, such as 5G and beyond, to improve the efficiency of CSI reporting.
  • It can be used in UE devices to enhance the accuracy of channel state information, which is crucial for optimizing wireless communication performance.

Problems solved by this technology:

  • The method addresses the challenge of determining the appropriate frequency granularity for CSI reporting based on the number of physical resource blocks.
  • It solves the problem of efficiently transmitting CSI reports over the uplink channel, ensuring accurate and timely feedback to the network.

Benefits of this technology:

  • By adapting the frequency granularity of CSI reporting, the method optimizes the utilization of network resources and improves overall system performance.
  • It enables UE devices to provide more accurate and reliable channel state information, leading to better communication quality and higher data rates.
  • The method enhances the efficiency of wireless communication systems by reducing unnecessary signaling and minimizing interference.


Original Abstract Submitted

A method for operating a user equipment (UE) comprises receiving channel state information (CSI) reporting configuration information including a CSI reporting band and a frequency granularity of CSI reporting, where the CSI reporting band is within a bandwidth part (BWP) comprising M physical resource blocks (PRBs), and the frequency granularity of CSI reporting is based on whether M<N, where N is a threshold; identifying the frequency granularity of CSI reporting; generating a CSI report with the identified frequency granularity, wherein the CSI report includes at least one of a precoding matrix indicator (PMI) and a channel quality indicator (CQI); and transmitting the CSI report over an uplink (UL) channel.
