METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17990122 titled 'METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR THE SAME

Simplified Explanation

The present invention is a method for a User Equipment (UE) to report Channel State Information (CSI) in a wireless communication system. The method involves the following steps:

  • The UE receives a Radio Resource Control (RRC) signaling from a base station, which includes multiple reporting settings.
  • Each reporting setting consists of a list of time offsets representing when to transmit a CSI report.
  • The UE forms multiple lists of time offsets based on the reporting settings received from the base station.
  • The UE also receives Downlink Control Information (DCI) from the base station, which triggers the CSI report.
  • The DCI includes an index value that determines the time at which the CSI report should be transmitted on a Physical Uplink Shared Channel (PUSCH).
  • Based on the DCI, the UE determines multiple list entries.
  • The UE identifies the largest value among the list entries, which becomes the second value.
  • Finally, the UE transmits the CSI report on the PUSCH according to the second value.

Potential applications of this technology:

  • Wireless communication systems, such as cellular networks, can benefit from this method for efficient reporting of CSI by UEs.
  • It can be applied in various wireless communication standards, including 4G LTE and 5G NR, to improve the overall system performance.

Problems solved by this technology:

  • The method solves the problem of efficiently reporting CSI by UEs in a wireless communication system.
  • It addresses the challenge of determining the appropriate time to transmit CSI reports based on different reporting settings received from the base station.

Benefits of this technology:

  • The method allows UEs to report CSI more effectively, leading to improved system performance and better resource allocation.
  • It enables better channel estimation and feedback, which can enhance the overall quality of wireless communication.
  • The method provides flexibility in choosing the time to transmit CSI reports, based on the received reporting settings, resulting in optimized utilization of network resources.


Original Abstract Submitted

The present invention provides a method of reporting, by a UE, CSI in a wireless communication system, the method comprising: receiving, from a base station, a RRC signaling that comprises a plurality of reporting settings, wherein each reporting setting comprises a corresponding list of first values representing time offsets for transmitting a CSI report, forming a plurality of lists of first values; receiving, from the base station, DCI triggering the CSI report, wherein the DCI comprises an index value related to a time at which to transmit the CSI report on a PUSCH; determining, based on the DCI, a plurality of list entries; determining a second value that is largest among the plurality of list entries; and transmitting, to the base station, the CSI report on the PUSCH based on the second value.
