Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless telecommunications, multi-mode user equipment (UE) faces challenges in measuring signal strength from microtechnology-based networks during macrotechnology-based communications, which is essential for handoff processes between macrocells and microcells, as traditional methods cannot simultaneously receive and measure signals from both technologies.
Innovation Solution
The implementation of a processor in multi-mode UE to create gaps in macrotechnology-based data transmissions for measuring microtechnology-based signal strength, using various techniques such as defining common gap patterns, requesting additional gaps, or utilizing idle time within data strings for signal measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multi-mode UE continuously receives macrotechnology-based signals for communication, then communication reliability is maintained, but the ability to measure microtechnology-based signal strength is lost
Solution Approach 1:
The patent implements periodic measurement gaps within the continuous macrotechnology communication framework. The UE periodically suspends macrotechnology reception during predetermined time intervals (measurement gaps) to measure microtechnology signal strength, then resumes macrotechnology communication. This periodic action allows both communication reliability and measurement capability to coexist by alternating between the two functions in a structured manner.
2Adaptability or versatility
If measurement gaps are created for inter-RAT signal measurement, then handoff capability is improved, but data transmission efficiency deteriorates
Solution Approach 1:
The patent dynamically adjusts the measurement gap configuration based on communication conditions. The network can configure different gap patterns (e.g., gap repetition factor, gap length) depending on the UE's communication state, the importance of handoff measurement, and the tolerance for transmission interruption. This dynamic adaptation allows the system to optimize the balance between handoff capability and data transmission efficiency in real-time.
Solution Approach 2:
The patent implements partial measurement by creating gaps only during specific periods when handoff measurement is critical, rather than continuously interrupting communication. The measurement gaps are applied partially in time, allowing full data transmission efficiency during non-gap periods while providing sufficient measurement opportunities to improve handoff capability when needed.
3Adaptability or versatility
If multiple gap patterns are defined for different measurement scenarios, then measurement flexibility is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal gap pattern framework where a single configurable gap structure can serve multiple measurement scenarios (intra-RAT, inter-RAT, different frequencies). Instead of implementing separate dedicated gap patterns for each measurement type, the system uses a multi-functional gap configuration that can be adapted through parameters like gap repetition factor and offset values, reducing overall system complexity while maintaining measurement flexibility.
