NR-Report Config

Last updated on 


In 5G New Radio (NR) networks, the "NR-Report Config" refers to a technical configuration that is used to define and control how the User Equipment (UE) reports measurement or event-related information to the network. The NR-Report Config is essential for network optimization, mobility management, and ensuring efficient radio resource utilization. Here's a detailed technical explanation of the NR-Report Config:

Measurement and Reporting in 5G NR:

  • In 5G NR, UEs regularly perform measurements on neighboring cells and various radio quality parameters, such as signal strength, signal quality, and interference levels.
  • These measurements are crucial for various network functions, including handover decisions, mobility management, and interference mitigation.

Report Configuration:

  • The NR-Report Config is a configuration parameter set by the network for a specific UE. It defines:
  • The type of measurements or events the UE should perform.
  • The reporting criteria and conditions that trigger reporting.
  • The reporting period or triggering threshold.

Measurement Types:

  • The NR-Report Config can specify various types of measurements, including:
  • Intra-frequency measurements: Measurements within the same frequency band or carrier.
  • Inter-frequency measurements: Measurements across different frequency bands.
  • Inter-RAT (Radio Access Technology) measurements: Measurements involving non-5G networks, such as 4G LTE or legacy networks.
  • Event-triggered measurements: Measurements that are triggered by specific events, such as handover candidates becoming better than the current serving cell.
  • Periodic measurements: Measurements performed at regular intervals.

Reporting Criteria:

  • The report configuration specifies the criteria that trigger reporting. For example:
  • Signal strength exceeding a certain threshold.
  • Quality degradation below a specified level.
  • A handover event when a neighboring cell becomes more suitable.
  • An event related to mobility, such as entering or leaving a restricted area.

Reporting Period:

  • For periodic measurements, the NR-Report Config defines the reporting period, indicating how often the UE should send measurement reports to the network.
  • The reporting period can be configured based on network requirements, user mobility, and interference conditions.

UE Processing:

  • The UE continuously monitors the specified measurements based on the configured NR-Report Config.
  • When the reporting criteria are met or when the reporting period expires, the UE generates a measurement report.

Measurement Report Format:

  • The measurement report includes information about the measured parameters, the timing of the measurement, and other relevant data.
  • The report format conforms to the 3GPP (3rd Generation Partnership Project) specifications.

Report Transmission:

  • The UE sends the measurement report to the network, typically through dedicated control channels or signaling messages.
  • The network uses the received measurement reports for various purposes, such as optimizing handover decisions, managing mobility, and enhancing network performance.

Dynamic Configuration:

  • The NR-Report Config can be dynamically updated by the network based on changing network conditions or UE mobility.
  • This dynamic configuration allows the network to adapt to varying radio conditions and optimize resource utilization.

In summary, the NR-Report Config is a critical aspect of 5G NR networks that enables UEs to perform measurements and report relevant information to the network. This information is essential for network management and ensuring a seamless user experience by enabling efficient handovers, interference management, and mobility management. The precise configuration parameters can vary depending on the specific network requirements and deployment scenarios.
