Terminal Device Capability Reporting for Dynamic Overhead Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems limit peak air interface throughput due to fixed overhead values, which restrict maximum instantaneous scheduling rates, leading to lower actual peak rates compared to the maximum supported by terminal devices.
Innovation Solution
Terminal devices report capability information to network devices about their supported transmission rates and overheads, allowing for flexible scheduling based on actual capabilities rather than fixed overhead values, enabling higher peak data rates and increased network throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed overhead value is used for scheduling, then system simplicity is maintained, but the instantaneous peak throughput cannot reach the maximum supported by the terminal
Solution Approach 1:
The patent introduces dynamic overhead adjustment by allowing the network device to configure different overhead values for different terminals based on their capabilities. Instead of using a fixed overhead value for all terminals, the system dynamically adapts the overhead parameter to match each terminal's actual processing capability, thereby enabling higher instantaneous peak throughput for capable terminals while maintaining system manageability through standardized configuration procedures.
Solution Approach 2:
The patent changes the overhead parameter from a fixed system-wide value to a configurable terminal-specific value. The network device determines appropriate overhead values based on terminal capabilities and configures them accordingly. This parameter change allows the system to optimize throughput for each terminal individually, resolving the contradiction between maintaining simplicity and achieving maximum performance.
2Productivity
If the average overhead is used as the lowest overhead for scheduling, then scheduling is simplified, but the actual average peak rate becomes lower than the expected peak rate
Solution Approach 1:
The patent enables the overhead parameter to be changed from a fixed average value to configurable values that reflect actual terminal capabilities. The network device can set different overhead levels (e.g., 0.07 or 0.14) based on each terminal's processing capability, allowing the actual average peak rate to reach its expected maximum while maintaining standardized scheduling procedures.
Solution Approach 2:
The patent implements preliminary capability assessment where the network device evaluates terminal capabilities before configuring overhead values. This preliminary action allows the system to pre-determine appropriate overhead settings for each terminal, ensuring that scheduling can operate at optimal rates without requiring complex real-time adjustments during data transmission.
3Productivity
If a fixed overhead value is used, then system consistency is maintained, but terminals with lower actual overhead capability cannot achieve their maximum throughput
Solution Approach 1:
The patent allows the overhead parameter to be adapted to each terminal's actual capabilities. Terminals with lower overhead requirements (e.g., 0.07) can be configured with appropriate values to achieve their maximum throughput, while terminals with higher requirements (e.g., 0.14) receive corresponding configurations. This parameter adaptation resolves the contradiction between maintaining system consistency and enabling terminal-specific optimization.
Solution Approach 2:
The patent applies local quality by allowing different overhead values to be assigned to different terminals based on their specific capabilities. Instead of imposing a uniform overhead value across all terminals, the system tailors the overhead parameter to each terminal's local characteristics, enabling each terminal to operate at its optimal performance level while maintaining overall system coherence through standardized configuration mechanisms.

AI summary
This application provides a communication method and apparatus. A terminal device can report capability information to a network device based on a capability of the terminal device, to enable the network device to learn that the terminal device supports a peak data rate higher than a peak data rate determined based on a specified overhead, or enable the network device to learn that the terminal device supports an overhead lower than a specified overhead, so that when scheduling data of the terminal device, the network device performs scheduling based on an overhead lower than the specified overhead, instead of performing scheduling based on only the specified overhead in the conventional technology, to increase a network throughput.
