NR UE Positioning with Preconfigured Measurement Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in accurately localizing user equipment (UE) positions, leading to increased latency due to measurement gaps and resource allocation delays when transmitting position-related information.
Innovation Solution
A method and apparatus for UE localization in wireless communication systems that reduce latency by utilizing configured measurement gaps and uplink resource grants, enabling efficient position measurement reporting without dynamic allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are introduced for position measurement, then positioning capability is enabled, but latency increases due to measurement gap delays
Solution Approach 1:
The patent applies preliminary action by pre-configuring measurement gaps and uplink resources before position measurement is needed. The network side device configures measurement gap patterns and uplink resource grants in advance, allowing the UE to perform position measurements without waiting for dynamic allocation. This reduces latency while maintaining positioning accuracy.
2Adaptability or versatility
If dynamic resource allocation is used for position reporting, then resource flexibility is improved, but latency increases due to allocation delays
Solution Approach 1:
The patent implements preliminary action by pre-allocating uplink resources for position measurement reporting. The network side device configures uplink resource grants in advance that the UE can use directly for position reporting, eliminating the need for dynamic resource allocation and associated delays while maintaining flexibility in resource usage.
Solution Approach 2:
The patent ensures continuity of useful action by establishing continuous availability of uplink resources for position reporting. Through pre-configuration of uplink resource grants, the system maintains continuous capability for position measurement and reporting without interruption or delay for resource allocation.
3Measurement precision
If measurement gaps are configured for positioning, then positioning function is activated, but processing complexity increases
Solution Approach 1:
The patent reduces processing complexity by applying preliminary action through pre-configuration of measurement gaps. The network side device sets up measurement gap patterns and timing information in advance, allowing the UE to execute position measurements through simple pre-established procedures rather than complex real-time calculations.

AI summary
A method performed by a base station in a wireless communication system is provided. The method includes receiving, from a location management function (LMF) entity, an NR positioning protocol A (NRPPa) message, determining measurement gap configuration information, based on the NRPPa message, transmitting, to a user equipment (UE), a radio resource control (RRC) reconfiguration message including the measurement gap configuration information, and performing a measurement gap activation procedure, based on the measurement gap configuration information.
