Dynamic Termination Target Adjustment for Reverse Link Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as those using the EV-DO Rev. A Standard, employ fixed termination targets for high-capacity and low-latency transmission modes, which do not dynamically adjust based on network conditions or usage rates, leading to suboptimal performance in varying network loads and application demands.
Innovation Solution
The system dynamically adjusts termination targets for RF communication channels by observing network conditions and usage rates, allowing for real-time negotiation and adjustment of transmission parameters such as sub-frames or time slots, enabling flexible and adaptive data transmission modes based on current network and application requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed termination targets are used for high-capacity and low-latency transmission modes, then device complexity is reduced and ease of operation is improved, but adaptability to varying network conditions and application demands deteriorates
Solution Approach 1:
The patent applies dynamics by making the termination target adjustable based on network conditions and application requirements. The system dynamically switches between fixed termination targets (for low complexity) and adjustable termination targets (for high adaptability), allowing the transmission control to adapt to varying network loads and application demands without requiring completely complex control mechanisms
Solution Approach 2:
The patent changes the parameter of termination target from a fixed value to an adjustable value based on network conditions. By monitoring network load, application requirements, and transmission performance, the system modifies the termination target parameter to optimize between high-capacity and low-latency modes, achieving adaptability without excessive complexity
2Productivity
If fixed termination targets are used, then device complexity is reduced, but transmission performance under varying network loads deteriorates
Solution Approach 1:
The system dynamically adjusts the termination target based on real-time network conditions to optimize data transmission rate. When network conditions favor high throughput, the termination target is configured for high-capacity mode; when latency is critical, it switches to low-latency mode, maximizing productivity without requiring permanently complex control logic
Solution Approach 2:
The termination target parameter is changed according to network conditions and application requirements. The system monitors transmission performance and adjusts the termination target parameter to optimize data rates, achieving high productivity by adapting the parameter rather than maintaining fixed complex control
3Adaptability or versatility
If dynamic adjustment of termination targets is implemented, then adaptability to network conditions is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic adjustment of termination targets through a negotiation mechanism between access terminal and access network. The system dynamically adapts to application demands by exchanging capability information and adjusting termination targets based on mutual agreement, achieving high adaptability while distributing the complexity between network entities rather than concentrating it in one device
4Productivity
If dynamic adjustment of termination targets is implemented, then transmission performance is improved, but device complexity increases
Solution Approach 1:
The system dynamically adjusts termination targets to optimize network performance based on real-time conditions. By implementing dynamic control only when needed (rather than fixed control always), the system achieves high productivity while keeping the control mechanism complexity manageable through conditional activation of dynamic adjustment
Solution Approach 2:
The termination target parameter is changed based on network performance metrics and application requirements. The system monitors performance indicators and adjusts the parameter to optimize throughput and latency, achieving improved network performance while the parameter-change approach keeps control complexity lower than full-blown dynamic control mechanisms

AI summary
Methods and apparatus for transmitting communications using a radio frequency (RF) communication channel are provided. A network condition and/or a usage level of the RF communication channel are determined. A designated duration is selected based, at least in part, on the network condition and/or usage level. A time period for transmitting a communication in the RF channel is selected such that the time period has a duration corresponding to the designated duration. A transmission in the RF communication channel is initiated during the time period. The designated duration may be adjusted based on further observations of network conditions and/or usage levels.
