Uplink Radio Frame Transmission Timing Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the varying Timing Advancement (TA) values for uplink radio frames cause transmission timing overlaps, leading to performance deterioration or increased overhead when trying to synchronize signals across multiple Base Stations or devices, especially in cooperative systems where different TA values result in overlapping transmission timings.
Innovation Solution
The method involves aligning uplink radio frames based on their respective TA values, either by rearranging their order or using offset values to compensate for timing differences, ensuring non-overlapping transmission without reducing frame length or increasing overhead, thus maintaining system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radio frames are transmitted with different TA values to multiple base stations, then uplink signal transmission to multiple base stations is enabled, but transmission timing overlaps occur causing performance deterioration
Solution Approach 1:
The patent segments the continuous transmission timeline by introducing gaps between transmissions to different base stations. Each radio frame transmission is divided into separate time slots with guard periods, preventing overlap while maintaining the ability to serve multiple base stations with different TA values.
Solution Approach 2:
The patent dynamically adjusts transmission timing based on TA values and buffer status. The transmission timing is not fixed but adapts to the specific TA requirements of each base station and the current buffer status, allowing optimal timing selection that prevents overlap while maintaining versatility.
2Reliability
If transmission timing is adjusted to avoid overlaps, then performance deterioration is prevented, but transmission efficiency decreases due to timing gaps
Solution Approach 1:
The patent changes the timing parameters dynamically based on buffer status and TA values. When buffer status allows, transmissions are scheduled closer together; when buffer status requires adjustment, larger gaps are introduced. This parameter adaptation optimizes the balance between preventing overlap and maintaining efficiency.
Solution Approach 2:
The patent applies timing gaps selectively rather than uniformly. Gaps are introduced only when necessary to prevent overlap given current TA values and buffer status, rather than using fixed conservative timing for all transmissions. This partial application of timing adjustment maintains efficiency while ensuring performance.
3Productivity
If buffer status is considered for timing selection, then transmission timing can be optimized, but complexity of timing management increases
Solution Approach 1:
The patent enables the electronic device to autonomously determine optimal transmission timing by evaluating its own buffer status and TA values without requiring complex external coordination. The device self-manages the timing selection process, simplifying the overall system complexity while achieving optimization.
Solution Approach 2:
The patent uses buffer status as feedback to adjust transmission timing decisions. The current buffer contents provide real-time information about transmission needs, allowing the system to adapt timing dynamically. This feedback mechanism enables optimization without requiring complex predictive algorithms or external control.
