Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional positioning methods (ECID, A-GNSS, OTDOA) are used in 5G networks, then positioning functionality is provided, but positioning accuracy and speed are insufficient for high number density scenarios
Solution Approach 1:
The patent segments the positioning process into multiple independent measurement types (downlink measurements, uplink measurements, reference signal time differences, RSRP, SINR) that can be performed simultaneously. This segmentation allows parallel processing of different measurement types, improving positioning speed while maintaining accuracy through the aggregation of multiple measurement results.
Solution Approach 2:
The patent introduces a new dimension to positioning by combining traditional downlink measurements with uplink measurements and multiple signal types (PRS, SRS, CSI-RS). This multi-dimensional approach enables more comprehensive position estimation, improving both accuracy and efficiency by utilizing additional measurement dimensions that were not simultaneously exploited in prior art.
2Productivity
If positioning measurements are performed for multiple UEs simultaneously, then number density increases, but latency increases and processing complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-configuring multiple measurement types (downlink, uplink, reference signals) to be ready for simultaneous execution. This preliminary preparation allows the system to rapidly process multiple UEs without sequential delays, reducing positioning latency while handling high number densities through pre-established measurement frameworks.
Solution Approach 2:
The patent ensures continuity of useful action by implementing continuous, simultaneous measurement processes for multiple UEs across different signal types. This continuous parallel processing eliminates idle time between measurements, maintaining high productivity for multiple UEs while minimizing latency through uninterrupted measurement streams.
3Measurement precision
If multiple measurement types are collected for position estimation, then positioning accuracy improves, but processing complexity and time increase
Solution Approach 1:
The patent applies universality by designing a multi-functional measurement framework that simultaneously handles downlink measurements, uplink measurements, reference signal time differences, RSRP, and SINR through a unified processing architecture. This universal approach improves positioning precision through diverse measurements while managing complexity through a single integrated system that processes all measurement types concurrently rather than through separate specialized systems.

AI summary
A method of determining a position of a user equipment (UE) relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The method of determining a position of a user equipment (UE) includes measuring, via at least one of a downlink (DL) or an uplink (UL), a first measurement of a set of measurements. The method further comprises estimating, at least in part, the position of the UE using the first measurement of the set of measurements.
