Time Division Duplex Pattern Slot Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems using time division duplex patterns face challenges in efficiently managing cyclic communication, particularly in ensuring reliable data transmission and adapting to varying communication slot arrangements, which can lead to degradation in communication quality due to interference from other wireless communication systems.
Innovation Solution
A communication system that controls cyclic communication by repeating a time division duplex pattern, allowing at least part of each communication cycle to be performed within one time division duplex pattern, and adjusts the arrangement of communication slots without changing the pattern, enabling flexible application to various applications and maintaining communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed time division duplex pattern is used for cyclic communication, then communication reliability is improved, but adaptability to varying communication requirements deteriorates
Solution Approach 1:
The communication cycle is segmented into multiple communication slots that can be independently configured and allocated. Each slot can be assigned to different communication purposes (control signals, data transmission, acknowledgments), allowing the system to maintain a reliable cyclic structure while adapting to varying requirements by reconfiguring slot assignments without changing the overall pattern framework.
2Adaptability or versatility
If communication slots are rearranged to adapt to different applications, then versatility is improved, but communication quality deteriorates due to interference from other wireless communication systems
Solution Approach 1:
The system employs periodic time division duplex patterns with fixed repetition intervals, creating predictable communication cycles. This periodic structure allows other systems to anticipate transmission patterns and avoid interference, while still permitting slot arrangement adjustments within each pattern to accommodate different application requirements. The periodic nature maintains communication quality by establishing stable, predictable timing.
3Adaptability or versatility
If the time division duplex pattern is changed to meet different communication requirements, then adaptability is improved, but system complexity increases
Solution Approach 1:
The system implements dynamic slot allocation within a static time division duplex pattern framework. While the overall pattern structure remains fixed to simplify system design and implementation, the arrangement and assignment of communication slots within each pattern can be dynamically adjusted to meet different communication requirements. This dynamic flexibility provides adaptability without increasing the fundamental system complexity.
