Channel Priority Indication Over Measurement Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data transmission is hindered during measurement gaps in the NR system, leading to increased transmission delay, particularly in scenarios with strict latency requirements like URLLC, due to the UE's inability to transmit or receive data simultaneously with inter-frequency measurements.
Innovation Solution
A method and apparatus that configures indication information for the UE to prioritize data transmission over measurement gaps by determining the priority of channels overlapping with measurement gaps, allowing the UE to continue data transmission when the channel priority is higher than the measurement gap priority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE performs inter-frequency measurement during measurement gap, then the measurement accuracy is improved, but the data transmission delay increases
Solution Approach 1:
The patent makes the measurement gap configuration dynamic and adaptable by introducing priority-based mechanisms. The network can dynamically adjust whether to apply measurement gaps based on channel priority, and the UE can dynamically switch between performing measurements or transmitting data depending on the prioritization outcome. This resolves the contradiction by making the system flexible rather than rigidly forcing measurements during gap periods.
Solution Approach 2:
The patent changes the parameter of measurement gap application by introducing priority comparison logic. Instead of always applying measurement gaps, the system now evaluates channel priority against measurement gap priority and conditionally applies or skips measurements. This parameter change allows the system to adapt measurement behavior based on transmission requirements, reducing delay when data transmission is critical.
2Loss of time
If the UE prioritizes data transmission over measurement gap, then the data transmission delay is reduced, but the measurement accuracy may deteriorate
Solution Approach 1:
The patent changes the measurement gap application parameter from a fixed rule to a conditional decision based on priority comparison. By evaluating whether channel priority exceeds measurement gap priority, the system dynamically adjusts measurement behavior, allowing measurements to be skipped only when necessary for high-priority transmissions, thus minimizing impact on measurement accuracy while reducing delay when needed.
Solution Approach 2:
The patent implements a feedback mechanism where the UE compares channel priority information with measurement gap priority information and makes real-time decisions. This feedback loop allows the system to continuously evaluate whether to perform measurements or transmit data based on current conditions, ensuring measurement accuracy is maintained when possible while allowing delay reduction when transmission urgency demands it.
3Productivity
If the UE skips measurement during high-priority data transmission, then the productivity is improved, but the reliability of cell switching may deteriorate
Solution Approach 1:
The patent changes the measurement execution parameter from mandatory to conditional based on priority evaluation. By comparing channel priority against measurement gap priority, the system intelligently determines whether to skip measurements during transmission, improving productivity when high-priority data requires immediate transmission while maintaining reliability when measurements are more critical for cell switching decisions.

AI summary
The present application discloses an information configuration method, a data transmission method, and an apparatus, for solving the problem in which a measurement gap blocks data transmission and accordingly increases a transmission delay. An embodiment of the present application comprises: a network-side apparatus configuring indication information of a priority level of a channel with respect to that of a measurement gap; a terminal receiving the indication information, and performing configuration according to the indication information; and if the measurement gap and the channel for transmitting data overlap, the terminal determining, according to the priority level indicated by the indication information, whether to continue measurement or to transmit data via the channel. In scenarios having high requirements on delays, a network side can configure a priority level of a channel to be higher than that of a measurement gap, and if a channel and a measurement gap overlap, a terminal can continue to transmit data, thereby avoiding a transmission delay caused by the measurement gap, and accordingly reducing transmission delay.
