Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G network technologies face inefficiencies in data transmission and reference signal measurements due to the need for longer measurement gaps in high frequency ranges, which can lead to wasted opportunities for improving communication throughput.
Innovation Solution
Implementing a measurement gap configuration specific to high frequency ranges with shorter time durations and repetition periods, allowing for optimized data transmission and reference signal measurements by allowing the UE to retune its RF circuitry more efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are extended to accommodate RF retuning time in high frequency ranges, then measurement capability is achieved, but communication throughput is reduced
Solution Approach 1:
The patent applies dynamics by making the measurement gap configuration adaptive to frequency ranges. The system dynamically selects different measurement gap lengths (e.g., 0.5ms, 1ms, 1.5ms, 3ms, 4ms, 5ms, 6ms, 8ms, 10ms, 12ms, 15ms, 20ms) based on the specific frequency range being measured, allowing the measurement gap duration to be optimized for each frequency range rather than using a fixed duration for all ranges.
Solution Approach 2:
The patent changes the parameter of measurement gap length according to frequency range. By establishing a correspondence between frequency ranges and specific measurement gap durations, the system adjusts the measurement gap parameter to match the RF retuning time requirements of different frequency ranges, thereby minimizing the impact on communication throughput while ensuring adequate measurement capability.
2Device complexity
If a single measurement gap configuration is used for all frequency ranges, then device complexity is reduced, but measurement accuracy deteriorates in high frequency ranges
Solution Approach 1:
The patent segments the measurement gap configuration into multiple configurations, each tailored to specific frequency ranges. Instead of using a single universal measurement gap configuration, the system divides the configuration space into frequency-range-specific segments, allowing each segment to be optimized for the characteristics of its corresponding frequency range.
Solution Approach 2:
The patent applies local quality by providing different measurement gap configurations for different frequency ranges. Each frequency range receives a measurement gap configuration that is locally optimized for its specific RF retuning time requirements, rather than applying a uniform configuration across all frequency ranges.
3Reliability
If measurement gap length is increased to ensure adequate retuning time, then RF retuning reliability is improved, but data transmission opportunities are lost
Solution Approach 1:
The patent changes the measurement gap length parameter based on frequency range to achieve the right balance. By setting the measurement gap length to match the actual RF retuning time requirements of each frequency range (e.g., shorter gaps for lower frequencies, longer gaps for higher frequencies), the system ensures reliable retuning while minimizing unnecessary time loss.
Solution Approach 2:
The patent applies partial action by providing just enough measurement gap duration to accommodate the RF retuning time requirement for each frequency range, rather than using excessively long measurement gaps that would guarantee reliability but cause unnecessary data transmission loss.

AI summary
The present application relates to devices and components including apparatus, systems, and methods to perform measurements on reference signals based on measurement gaps. In an example, a device supports a frequency range that includes frequencies equal to or larger than 52.6 GHz. Measurement gap capability information is used to indicate and/or determine whether a measurement gap is supported for this frequency range. If so, measurement gap configuration can be defined and can include a measurement gap length and/or a measurement gap repetition period defined based on the frequencies being equal to or larger than 52.6 GHz.
