Communication Apparatus Partial Path Reporting via Waypoint Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing framework for reporting path information in Release 15 does not efficiently handle partial changes or additions to path information, leading to redundant reporting and potential deterioration in signaling efficiency.
Innovation Solution
A communication apparatus and method that allow for the transmission of partial changes or additions to path information by including identification information for waypoint-related information, enabling the reporting of only the changed parts of the path information rather than the entire path information.

Engineering Contradiction Analysis
1Loss of information
If the existing framework for reporting path information is used, then the path information can be reported to the base station, but redundant reporting occurs and signaling efficiency deteriorates
Solution Approach 1:
The path information is segmented into individual waypoint elements, each with its own identifier. This allows the terminal to report only the specific waypoint elements that have changed (added, removed, or modified) rather than reporting the entire path information structure, thereby reducing redundant signaling and improving efficiency.
Solution Approach 2:
The invention extracts and reports only the necessary subset of path information - specifically, the changed waypoint elements - rather than transmitting the complete path information. By identifying and reporting only the differential changes (additions, deletions, modifications), the signaling overhead is significantly reduced while maintaining information completeness.
2Reliability
If the entire path information is reported every time, then the base station receives complete path information, but radio resources are wasted and power consumption increases
Solution Approach 1:
Instead of reporting the complete path information structure every time, the invention applies partial action by reporting only the specific waypoint elements that have changed. This partial reporting approach maintains the reliability and completeness of the path information at the base station while significantly reducing the energy consumption and radio resource usage required for transmission.
3Reliability
If the entire path information is reported every time, then the base station receives complete path information, but radio resources are wasted
Solution Approach 1:
The path information is segmented into individual waypoint elements with unique identifiers, enabling the system to transmit only the specific segments (waypoint elements) that have changed. This segmentation allows the base station to maintain complete and reliable path information while minimizing radio resource consumption by avoiding redundant transmission of unchanged elements.
Solution Approach 2:
The invention extracts and transmits only the essential changed portions of the path information (specific waypoint elements) rather than the entire structure. This extraction approach ensures that the base station receives complete and accurate path information while significantly reducing the quantity of radio resources consumed during transmission.
