Tracking Resource Configuration for Non-Cellular System SRS Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-cellular systems, TPs with different tracking resources cannot correctly identify the SRS sent by a terminal, leading to inaccurate measurement information feedback and poor service performance, as only TPs with matching tracking resources can detect the SRS.
Innovation Solution
A resource configuration method that dynamically ensures all TPs within an LE have the same tracking resource, achieved by determining a shared tracking resource in the time-frequency resource of each TP, allowing all TPs to detect the SRS and send measurement information to the LE, thereby improving service performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If tracking resources of TPs are dynamically divided based on service load, then resource utilization is optimized, but SRS identification accuracy deteriorates because only TPs with matching tracking resources can detect the SRS
Solution Approach 1:
The patent segments tracking resources by introducing dedicated tracking resources separate from service resources. Each TP is configured with specific tracking resources (time-frequency resources) that are independent of its dynamically divided service resources. This segmentation allows TPs to have consistent tracking resources for SRS detection while maintaining flexible service resource allocation based on load conditions.
Solution Approach 2:
The patent creates universal tracking resources that are shared across all TPs within an LE, making these resources multi-functional for SRS detection regardless of which TP is currently serving the terminal. This universality ensures that any TP can detect the SRS on the tracking resource, enabling accurate measurement information feedback while service resources remain dynamically allocated.
2Productivity
If each TP uses different tracking resources, then service load optimization is improved, but service performance deteriorates due to inaccurate measurement information feedback
Solution Approach 1:
The patent separates tracking resource management from service resource management. Tracking resources are configured independently at the LE level and are common across all TPs, while service resources are dynamically allocated at the TP level based on service load. This segmentation resolves the contradiction by allowing service load optimization without compromising measurement accuracy and service performance.
Solution Approach 2:
The patent introduces tracking resources as an intermediary mechanism between the LE and TPs. These tracking resources serve as a common reference point that enables all TPs to participate in SRS detection and measurement information feedback, while the actual service provision remains optimized through dynamic service resource allocation. The tracking resources mediate between the need for consistent measurement capability and flexible service optimization.

AI summary
This application provides a resource configuration method and apparatus, applied to a non-cellular system NCS that includes a plurality of transmission points TPs. The method includes: determining a tracking resource in a time-frequency resource of each TP, where time-frequency resources of all the TPs are the same, and tracking resources determined for all the TPs are the same; generating tracking resource configuration information based on a time-frequency resource occupied by the tracking resource; and sending the tracking resource configuration information to each TP, so that each TP detects, on the tracking resource, a sounding reference signal SRS sent by a terminal, so as to improve NCS service performance.
