Uplink Collision Control for Repeated Low-Priority Transmissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods do not adequately address the conflict and transmission of low-priority uplink signals when they repeatedly collide with high-priority uplink signals, leading to inappropriate transmission of low-priority signals.
Innovation Solution
A terminal is equipped with a control section that determines whether to transmit or not transmit low-priority uplink signals based on collision detection with high-priority signals, ensuring appropriate transmission by avoiding overlapping transmission times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal repeatedly transmits low-priority uplink signals without collision detection, then the transmission continuity of low-priority signals is maintained, but collisions with high-priority signals occur leading to inappropriate transmission
Solution Approach 1:
The terminal performs collision detection between low-priority uplink signals and high-priority uplink signals before transmission. This preliminary action identifies potential collisions in advance, allowing the terminal to determine whether to transmit or skip transmission of low-priority signals, thereby ensuring transmission appropriateness without excessive control complexity
Solution Approach 2:
The uplink signal transmission is segmented into high-priority and low-priority channels with distinct handling mechanisms. The low-priority signal transmission is divided into multiple transmission sections, and collision detection is performed for each section independently, enabling fine-grained control over transmission decisions
2Productivity
If the terminal transmits both high-priority and low-priority uplink signals simultaneously, then the transmission efficiency is improved, but signal collisions occur leading to transmission errors
Solution Approach 1:
The terminal implements a feedback mechanism where collision detection results from comparing low-priority and high-priority signal transmission sections feed back into transmission decisions. When collisions are detected, the terminal adjusts transmission behavior accordingly, balancing transmission efficiency with signal reliability
Solution Approach 2:
The transmission strategy dynamically adjusts based on collision detection results. The terminal can switch between transmitting low-priority signals, skipping transmission, or prioritizing high-priority signals depending on real-time collision conditions, thereby maintaining both efficiency and reliability
3Reliability
If the terminal performs collision detection and selective transmission of low-priority signals, then transmission appropriateness is improved, but additional overhead is introduced
Solution Approach 1:
The terminal performs collision detection selectively rather than universally for all transmission scenarios. The detection and selective transmission mechanism is applied only when necessary to resolve priority conflicts, reducing unnecessary overhead while maintaining transmission appropriateness
Solution Approach 2:
The transmission parameters of low-priority signals are dynamically changed based on collision detection results. The terminal adjusts transmission presence or absence in different transmission sections, optimizing the balance between transmission appropriateness and overhead by transmitting only when appropriate

AI summary
A terminal includes: a control section that determines, when a collision occurs between a first transmission section for a first uplink data signal in a first uplink data channel and one of a plurality of second transmission sections to repeatedly transmit a second uplink data signal in a second uplink data channel, whether to perform transmission or non-transmission of the second uplink data signal in one or more of the second transmission sections where the collision does not occur, the second uplink data signal being a signal whose priority is that of lower than the first uplink data signal; and a communication section that transmits the first uplink data signal and the second uplink data signal when the transmission is determined to be performed.
