Measurement Gap Skipping for Wireless Packet Delay Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Measurement gaps (MGs) in wireless communication systems increase packet delay for real-time multimedia traffic and extend transmission time for burst traffic, challenging the meeting of packet budget delay (PDB) requirements.
Innovation Solution
A user equipment (UE) transmits a communication with an MG skipping indication to skip measurements during skipped MG occasions, allowing for wireless communication operations to continue, thereby mitigating delays in packet transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement gaps are used to perform inter-frequency and inter-RAT measurements, then measurement capability and mobility are improved, but packet delay increases for real-time multimedia traffic
Solution Approach 1:
The patent segments measurement gap occasions into two types: regular MG occasions for performing measurements and skipped MG occasions for maintaining continuous data transmission. This segmentation allows the system to selectively suspend measurements during time-critical data transmissions while maintaining measurement capability during non-critical periods, thereby reducing packet delay while preserving measurement functionality.
Solution Approach 2:
The patent implements periodic measurement gap occasions with a configured periodicity, where certain periods are skipped based on data transmission requirements. This periodic structure with selective skipping enables the system to balance measurement needs against real-time transmission demands, reducing delay for time-sensitive traffic while maintaining periodic measurement capability.
2Reliability
If measurement gaps are used to perform neighbor cell measurements, then mobility management is improved, but transmission time is extended for burst traffic
Solution Approach 1:
The patent divides measurement gap occasions into segments that can be selectively executed or skipped. By segmenting the measurement schedule and allowing selective skipping of certain MG occasions, the system can prioritize burst traffic transmission while maintaining mobility management through periodic measurements, thus reducing overall transmission time without completely sacrificing mobility capability.
Solution Approach 2:
The patent introduces dynamic skipping of measurement gap occasions based on real-time data transmission conditions. The UE can dynamically determine whether to skip an MG occasion based on whether data is available for transmission, making the measurement schedule flexible rather than rigid. This dynamic approach reduces transmission time for burst traffic while maintaining mobility management when measurements are more critical.
3Loss of time
If measurement gaps are suspended to allow data transmission, then packet delay is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent maintains periodic measurement gap occasions even when some occasions are skipped. This periodic structure ensures that measurements continue at regular intervals, preserving measurement precision over time while allowing flexibility to skip occasions when data transmission urgency requires it. The periodic nature ensures measurements are not completely suspended, maintaining accuracy for mobility management.
Solution Approach 2:
The patent changes the temporal parameters of measurement gap execution by introducing a skipping mechanism. Instead of fixed periodic execution, the system dynamically adjusts which MG occasions are executed based on data transmission conditions. This parameter change allows the system to optimize between measurement precision and transmission delay by selectively executing measurements when conditions permit.
