PUSCH Resource Configuration for Positioning Measurement Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of directly sending positioning measurement results from User Equipment (UE) to a base station and then to the Location Management Function (LMF) results in a large reporting time delay, affecting positioning accuracy.
Innovation Solution
The method involves acquiring positioning measurement results and sending them through a Physical Uplink Shared Channel (PUSCH) resource, reducing reporting time delay and improving positioning accuracy by configuring and utilizing granted PUSCH resources indicated by RRC and DCI signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If positioning measurement results are sent through traditional channels (directly from UE to base station to LMF), then the transmission path is simple, but the reporting time delay is large
Solution Approach 1:
The network device pre-configures PUSCH resources for positioning measurement result reporting before the UE needs to send results. This preliminary configuration includes setting up RRC signaling for resource allocation and DCI signaling for activation, so that when positioning results need to be reported, the UE can immediately use the pre-prepared resources without waiting for resource allocation, thereby reducing reporting time delay
Solution Approach 2:
The patent introduces a base station as an intermediary node between the UE and the LMF. The base station receives positioning measurement results from the UE via pre-configured PUSCH resources, then forwards them to the LMF. This intermediary approach enables more efficient resource management and reduces the direct reporting delay compared to traditional transparent transmission methods
2Productivity
If PUSCH resources are pre-configured through RRC and activated by DCI signaling, then reporting speed is improved, but signaling overhead increases
Solution Approach 1:
RRC signaling is used to pre-configure multiple PUSCH resource sets in advance, including resource parameters such as time-frequency allocation, modulation schemes, and coding rates. This preliminary configuration stores resource templates that can be quickly activated without detailed signaling, reducing the overhead compared to dynamic resource allocation
Solution Approach 2:
The system dynamically activates specific pre-configured PUSCH resources based on positioning reporting needs. DCI signaling provides dynamic activation by indicating which pre-configured resource set to use, allowing the system to adapt to varying positioning requirements while maintaining low signaling overhead through selective activation rather than full reconfiguration

AI summary
A positioning measurement result sending method includes: a user equipment (UE) obtaining a positioning measurement result, and sending the positioning measurement result by means of a PUSCH resource.
