Deactivating Repetitions for Periodic Wireless Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face inefficiencies in managing repetitions of periodic communications, leading to resource wastage when initial transmissions are successful, as they continue to transmit redundant data to ensure reliability, consuming network and device resources.
Innovation Solution
Implementing a mechanism for user equipment (UE) and base stations to deactivate repetition transmissions when a threshold number of successful initial transmissions are confirmed, using beamforming and periodic resource configurations to reduce unnecessary repetitions and conserve resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repetition transmissions are continuously performed to ensure reliability, then communication reliability is improved, but network resource consumption increases
Solution Approach 1:
The patent implements dynamic deactivation of repetition transmissions based on real-time channel conditions and transmission success. The system transitions from static continuous repetitions to dynamic conditional repetitions, where repetitions are deactivated when channel quality indicates successful initial transmission, thereby reducing unnecessary resource consumption while maintaining reliability when needed
Solution Approach 2:
The system employs feedback mechanisms to monitor transmission success and channel conditions. Based on feedback from successful initial transmissions, the system adjusts repetition behavior by deactivating further repetitions, creating a closed-loop control system that balances reliability and resource efficiency
2Reliability
If repetition transmissions are continuously performed to ensure reliability, then communication reliability is improved, but device resource consumption increases
Solution Approach 1:
The user equipment dynamically adjusts its transmission behavior by deactivating repetition transmissions when initial transmissions succeed. This dynamic approach reduces device energy consumption by avoiding unnecessary repeated transmissions while maintaining the reliability benefit of having repetitions available when channel conditions deteriorate
3Reliability
If beamforming is used to focus transmissions, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary beamforming during initial transmissions to establish reliable communication. Once successful transmission is confirmed through feedback mechanisms, the complex beamforming and repetition operations are deactivated, reducing overall device complexity while maintaining reliability during critical transmission phases

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration for periodic communications. The UE may determine that the UE has successfully received a respective initial transmission in each transmission cycle of a threshold number of transmission cycles associated with the periodic communications. The UE may deactivate repetitions in one or more transmission cycles based at least in part on the determination. Numerous other aspects are provided.
