Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing service requirements in new generation communication systems, such as eMBB, URLLC, and mMTC, cannot be adequately met by utilizing licensed spectrum alone, necessitating the efficient use of unlicensed channel resources for data transmission.
Innovation Solution
A method and apparatus that determine an idle unlicensed channel resource from a plurality of unlicensed channel resources and set it as a working channel resource for data transmission, allowing for quick selection and utilization of available channels to reduce time delay and improve transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If licensed spectrum is used for data transmission, then service requirements can be met, but spectrum resources are insufficient to satisfy increasing service requirements
Solution Approach 1:
The patent combines licensed and unlicensed spectrum resources into a unified communication system. The terminal device can transmit data on licensed spectrum resources and switch to or combine with unlicensed spectrum resources, thereby merging two different resource pools to satisfy diverse and increasing service requirements without being constrained by licensed spectrum limitations alone.
2Quantity of substance
If unlicensed channel resources are used for data transmission, then spectrum resource availability increases, but channel selection and switching complexity increases
Solution Approach 1:
The terminal device autonomously performs channel selection, monitoring, and switching operations without requiring complex centralized control. The device independently detects channel availability, determines whether to switch between licensed and unlicensed channels, and manages the transmission process itself, thereby reducing overall system complexity despite the increased number of available channels.
Solution Approach 2:
The terminal device pre-configures multiple unlicensed channel resources and establishes readiness to switch between licensed and unlicensed channels. By preparing channel resources in advance and maintaining the capability to quickly transition between them, the system reduces real-time decision complexity while maximizing resource availability.
3Reliability
If multiple unlicensed channel resources are maintained, then transmission reliability improves, but time delay in channel selection increases
Solution Approach 1:
The terminal device pre-configures multiple unlicensed channel resources and maintains readiness to switch between them. By preparing channel options in advance and continuously monitoring their availability, the system can quickly select an appropriate channel when needed, reducing the time delay associated with channel selection while maintaining transmission reliability through multiple available options.
4Productivity
If channel switching is implemented between licensed and unlicensed spectrum, then resource utilization efficiency improves, but transmission stability decreases
Solution Approach 1:
The terminal device continuously monitors the availability and quality of both licensed and unlicensed channel resources, using this feedback to make intelligent switching decisions. By incorporating real-time channel state information into the selection process, the system can switch between licensed and unlicensed spectrum efficiently while maintaining transmission stability, avoiding switches to degraded or unavailable channels.
