Dynamic Measurement Gap Control for Low-Latency XR Wireless Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Buffer Status Reporting (BSR) mechanisms in wireless communication systems face challenges in meeting the low latency requirements of Extended Reality (XR) applications, leading to inefficiencies in data transmission and excessive resource waste.
Innovation Solution
A new mechanism is introduced to enhance data throughput and reduce latency by optimizing the reporting of delay-sensitive data to the base station, involving the reception of RRCReconfiguration messages, determining specific periods for transmission and reception, and managing measurement gaps based on downlink signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional Buffer Status Reporting (BSR) mechanisms are used in wireless communication systems, then the system maintains standard operation and compatibility, but it fails to meet the low latency requirements of Extended Reality (XR) applications, leading to excessive resource waste and inefficient data transmission
Solution Approach 1:
The patent implements dynamic measurement gap adjustment by determining whether to perform transmission and reception on specific serving cells during first and third periods based on downlink signals related to measurement gap deactivation. This dynamic adaptation allows the system to optimize latency for XR applications while maintaining standard operation, directly resolving the contradiction between meeting low latency requirements and maintaining data transmission efficiency.
2Measurement precision
If measurement gaps are continuously maintained for network measurement purposes, then measurement accuracy is preserved, but data transmission for XR applications experiences delays and resource waste increases
Solution Approach 1:
The patent implements periodic measurement gap deactivation by determining whether to perform transmission and reception during first and third periods based on downlink signals. This periodic approach allows the system to maintain measurement capabilities when needed while reducing measurement gap interruptions during XR data transmission, thereby preserving measurement accuracy while minimizing data transmission delays.
3Reliability
If measurement gap deactivation is not implemented, then network measurement coverage is maintained, but XR data transmission experiences excessive latency and resource waste
Solution Approach 1:
The patent implements dynamic measurement gap adjustment based on downlink signals related to measurement gap deactivation. This allows the system to maintain measurement coverage reliability while dynamically reducing measurement gap interruptions during XR data transmission, resolving the contradiction between maintaining measurement coverage and reducing XR data transmission latency.
