Uplink Early Termination for Overlapping Configured Grants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications networks, overlapping transmissions can lead to interference, and existing methods do not effectively manage uplink transmissions to prevent collisions and reduce latency for high-priority data.
Innovation Solution
Implementing early termination of uplink transmissions based on repetitions and overlapping configured grant resources, allowing only high-priority data to initiate channel occupancy, and using techniques like non-overlapping frequency resources and spatial beam differentiation to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink transmissions are allowed to overlap in configured grant resources, then resource utilization improves, but interference and collisions occur
Solution Approach 1:
The patent applies local quality by differentiating transmission priorities within configured grant resources. High-priority transmissions are allowed to overlap and preempt low-priority transmissions, while low-priority transmissions are terminated early to avoid interference. This creates localized quality differences in resource allocation based on transmission priority, resolving the contradiction between resource utilization and interference prevention.
Solution Approach 2:
The patent implements dynamic transmission termination where the duration of uplink transmissions is adjusted based on detected overlapping transmissions. When a high-priority transmission is detected, low-priority transmissions are dynamically terminated early. This dynamic adjustment allows resource utilization to improve when conditions permit while preventing interference when high-priority transmissions occur.
2Productivity
If uplink transmissions continue for full duration, then data throughput improves, but latency for high-priority data worsens due to collisions
Solution Approach 1:
The patent applies preliminary action by detecting overlapping transmissions before they cause complete collision. The receiving device detects the presence of high-priority transmissions in advance and triggers early termination of low-priority transmissions. This preliminary detection and response mechanism prevents latency issues before they fully manifest while maintaining overall throughput.
Solution Approach 2:
The patent implements partial action by allowing low-priority transmissions to proceed for part of their allocated duration until high-priority transmissions are detected. Once detected, the low-priority transmissions are terminated early. This partial execution approach balances throughput maintenance with latency reduction for high-priority data.
3Loss of time
If early termination is implemented, then latency for high-priority data improves, but device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the receiving device to autonomously detect overlapping transmissions and trigger early termination without complex centralized coordination. The system uses self-contained detection mechanisms where the receiving device monitors for high-priority transmissions and automatically manages termination of low-priority transmissions, reducing overall system complexity while achieving low latency.
Solution Approach 2:
The patent implements feedback mechanisms where transmission status information is exchanged between devices to coordinate early termination. The receiving device provides feedback about detected high-priority transmissions, which triggers the transmitting device to terminate low-priority transmissions early. This feedback loop achieves low latency with manageable complexity through distributed coordination.

AI summary
Apparatuses, methods, and systems are disclosed for early termination of an uplink transmission. One method includes starting to transmit a first uplink transmission with a first duration in a beginning of a CO period. The method includes determining to terminate the first uplink transmission earlier than an end of the first duration based on: repetitions associated with the first uplink transmission; or a duration of overlapping CG resources. The first uplink transmission can be sent in any of the overlapping CG resources, and each of the overlapping CG resources is associated with a different CG configuration than a CG configuration associated with another overlapping CG resource. The method includes terminating the first uplink transmission earlier than the end of the first duration.
