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

This abstract first appeared for US patent application 17981896 titled 'METHOD AND APPARATUS FOR MEASURING AND REPORTING CHANNEL STATE IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The patent application describes a communication method and system that combines 5G technology with IoT technology to support higher data rates and enable intelligent services in various domains.

  • The method involves a terminal in a wireless communication system.
  • The terminal receives information from a base station that configures a list of aperiodic trigger states for Channel State Information (CSI).
  • The terminal also receives Downlink Control Information (DCI) from the base station, which includes a CSI request field.
  • Each codepoint in the CSI request field is associated with a trigger state from the list, and a CSI Reference Signal (CSI-RS) is triggered based on the indicated trigger state.
  • The terminal identifies whether the Bandwidth Part (BWP) in which the CSI-RS is received is non-active.
  • If the BWP is non-active, the terminal skips the measurement of the CSI-RS.

Potential applications of this technology:

  • Smart home: The technology can be used to enable intelligent services in smart homes, such as automated control of appliances and devices.
  • Smart building: It can be applied to optimize energy usage, monitor and control building systems, and enhance security in smart buildings.
  • Smart city: The technology can contribute to the development of efficient transportation systems, smart infrastructure, and improved public services in smart cities.
  • Smart car/connected car: It can enable advanced features in vehicles, such as real-time traffic information, remote diagnostics, and autonomous driving capabilities.
  • Health care: The technology can be utilized for remote patient monitoring, telemedicine, and efficient healthcare delivery.
  • Digital education: It can support online learning platforms, virtual classrooms, and personalized educational experiences.
  • Smart retail: The technology can enhance customer experiences in retail environments through personalized offers, smart shelves, and efficient inventory management.
  • Security and safety services: It can be applied to improve surveillance systems, emergency response systems, and overall security and safety measures.

Problems solved by this technology:

  • The technology addresses the need for higher data rates beyond 4G systems and the integration of IoT capabilities.
  • It provides a method for efficient configuration and triggering of CSI-RS based on aperiodic trigger states.
  • It solves the problem of unnecessary measurement of CSI-RS in non-active Bandwidth Parts, reducing unnecessary resource consumption.

Benefits of this technology:

  • Higher data rates: The technology enables higher data rates compared to 4G systems, supporting faster and more reliable communication.
  • IoT integration: It allows for seamless integration of IoT devices and services, enabling intelligent and interconnected systems.
  • Efficient resource utilization: By skipping unnecessary CSI-RS measurements in non-active Bandwidth Parts, the technology optimizes resource allocation and improves overall system efficiency.
  • Enhanced user experience: The technology enables the development of intelligent services in various domains, enhancing user experiences and improving quality of life.


Original Abstract Submitted

The disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for IoT. The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure provides a method performed by a terminal in a wireless communication system. The method includes receiving, from a base station, information configuring a list of aperiodic trigger states for CSI; receiving, from the base station, DCI including a CSI request field, wherein each codepoint of the CSI request field is associated with one trigger state of the list and a CSI-RS is triggered based on a trigger state indicated by the CSI request field; identifying whether a BWP in which the CSI-RS is received is non-active; and in case that the BWP in which the CSI-RS is received is non-active, skipping a measurement of the CSI-RS.
