NR Cell Measurement Gap Adjustment for Lower Data Transmission Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a non-standalone 5G network architecture, electronic devices experience high delay in transmitting service data due to the need to repeatedly adjust the receiver frequency between LTE and NR cells to meet reporting conditions, leading to inefficient data transmission.
Innovation Solution
The electronic device determines whether it is located on the edge of an NR cell by analyzing measurement results and network signal parameters, and adjusts the measurement gap period accordingly to reduce transmission delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the electronic device periodically adjusts the receiver frequency to measure NR cells based on the measurement gap period, then the measurement accuracy of NR cells is improved, but the transmission delay of service data increases
Solution Approach 1:
The patent applies dynamics by making the measurement gap period adjustable rather than fixed. The network device dynamically configures different measurement gap periods based on device location and service requirements. Devices at cell edges receive longer measurement gap periods for accurate measurements, while devices with urgent service data transmission needs receive shorter periods to minimize delay, thus resolving the contradiction between measurement accuracy and transmission delay.
Solution Approach 2:
The patent implements local quality by providing differentiated measurement gap configurations to different devices based on their specific conditions. Devices located at NR cell edges receive customized longer measurement gap periods to ensure measurement accuracy, while devices in other locations or with different service requirements receive standard or shorter periods. This localized adaptation allows each device to achieve optimal balance between measurement quality and transmission efficiency.
2Reliability
If the measurement gap period is extended to improve measurement accuracy, then the measurement reliability is improved, but the service data transmission efficiency deteriorates
Solution Approach 1:
The patent applies parameter changes by modifying the measurement gap period parameter based on device location and service requirements. The network device configures different numerical values for the measurement gap period parameter - longer periods for devices needing reliable measurements (e.g., cell edge devices) and shorter periods for devices prioritizing transmission efficiency. This dynamic parameter adjustment resolves the contradiction between measurement reliability and transmission efficiency.
3Measurement precision
If the electronic device waits for frequency restoration to transmit service data, then the measurement process is completed accurately, but the data transmission latency increases
Solution Approach 1:
The patent resolves this contradiction through dynamic configuration of measurement gap periods. By adjusting the measurement gap duration and timing based on device location and service requirements, the system allows devices to complete necessary measurements with minimized waiting time. Devices with urgent data transmission needs can be configured with shorter measurement gaps or timing that avoids blocking critical data flows, thus reducing latency while maintaining measurement accuracy.
