User Terminal Measurement Gap Configuration for RRM Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Future radio communication systems, such as 5G and NR, face challenges in properly configuring Radio Resource Management (RRM) measurements, which can lead to a decline in communication throughput if not performed correctly.
Innovation Solution
The solution involves defining a user terminal and a corresponding radio communication method that includes configuring Measurement Gap (MG) patterns suitable for different Synchronization Signal (SS) block patterns, allowing for flexible MG configurations per frequency band and supporting both synchronous and asynchronous networks, enabling proper RRM measurements and reducing signaling overhead.

Engineering Contradiction Analysis
1Productivity
If RRM measurement is not properly configured, then communication throughput may decline, but configuring measurement gap patterns increases device complexity and signaling overhead
Solution Approach 1:
The patent applies parameter changes by configuring measurement gap patterns with specific parameters (gap length, repetition period, offset values) that are optimized for different SS block patterns. The base station adjusts these parameters dynamically based on the detected SS block pattern type (first or second pattern), thereby resolving the contradiction between maintaining high throughput and reducing configuration complexity.
Solution Approach 2:
The patent implements feedback mechanisms where the base station detects the SS block pattern type and uses this feedback information to appropriately configure the measurement gap pattern. This closed-loop approach ensures that the measurement gap configuration adapts to actual network conditions, maintaining throughput while avoiding unnecessary complexity from fixed or overly flexible configurations.
2Measurement precision
If measurement gap patterns are configured for different SS block patterns, then RRM measurement accuracy improves, but signaling overhead increases
Solution Approach 1:
The patent applies local quality by configuring different measurement gap patterns specifically tailored to different SS block pattern types. Instead of using a single universal configuration, the system applies localized optimization where the measurement gap parameters (length, offset, repetition period) are customized according to the detected SS block pattern, thereby improving measurement accuracy without requiring all possible configurations to be signaled.
Solution Approach 2:
The patent uses parameter changes to represent different measurement gap patterns through compact signaling. By varying key parameters (such as offset values and repetition periods) based on the SS block pattern type, the system can convey multiple configuration options through limited signaling overhead, rather than transmitting complete configuration sets for each scenario.
3Loss of time
If measurement gap repetition period is shortened to capture SS blocks, then measurement timing accuracy improves, but communication interruption increases
Solution Approach 1:
The patent applies dynamics by making the measurement gap repetition period adaptive rather than fixed. The base station dynamically adjusts the repetition period based on the detected SS block pattern type and timing characteristics, selecting shorter periods when SS blocks occur frequently and longer periods when they occur less frequently. This dynamic adjustment maintains measurement timing accuracy while minimizing unnecessary communication interruptions.
Solution Approach 2:
The patent uses parameter changes to optimize the measurement gap repetition period based on detected SS block patterns. By changing the repetition period parameter according to the specific pattern type (first or second pattern) and the timing of SS blocks, the system achieves accurate measurement timing without excessively increasing communication interruption duration.
