Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3GPP communication systems face challenges in efficiently managing video frame transmissions in diverse 5G deployment scenarios, particularly in ensuring ultra-low latency and high reliability for services like URLLC, while maintaining energy efficiency for mMTC devices.
Innovation Solution
The proposed solution involves a user equipment (UE) that generates video frames within a jitter window, using periodic radio resources for transmission, and prohibits further use of these resources for a period if data exchange occurs, optimizing resource allocation based on periodic configurations to enhance transmission procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If periodic radio resources are continuously allocated for video frame transmission, then transmission reliability is improved, but resource waste increases when frames are successfully transmitted early
Solution Approach 1:
The patent implements dynamic resource management by introducing a prohibit timer that adaptively controls the availability of periodic radio resources. When a video frame is successfully transmitted or cancelled, the timer prohibits further use of subsequent periodic resources, dynamically adjusting resource allocation based on actual transmission needs rather than continuous static allocation.
Solution Approach 2:
The system employs feedback mechanisms where the successful transmission or cancellation of a video frame triggers the activation of the prohibit timer. This feedback loop allows the system to learn from transmission outcomes and adjust subsequent resource usage, preventing waste by stopping resource allocation once transmission objectives are achieved.
2Loss of time
If periodic radio resources are used for video transmission, then transmission latency is reduced, but energy consumption increases for devices with periodic traffic patterns
Solution Approach 1:
The patent leverages the periodic nature of video frame transmission by configuring periodic radio resources that align with video frame generation intervals. The prohibit timer works in conjunction with this periodic structure to activate resources only when needed for actual frame transmission, then deactivate them to conserve energy, creating an efficient periodic on-demand resource allocation pattern.
3Adaptability or versatility
If multiple periodic-resources configurations are maintained for different video applications, then service versatility is improved, but device complexity increases
Solution Approach 1:
The prohibit timer mechanism serves as a universal control element that can be applied across multiple periodic-resources configurations and different video applications. Rather than implementing separate complex control logic for each configuration, the same timer-based prohibition mechanism universally manages resource release across all configurations, simplifying the overall system architecture.

AI summary
The present disclosure relates to a user equipment, UE, comprising the following. Processing circuitry of the UE operates a video application, according to which video frames are generated with a video frame periodicity. Each video frame is generated within a jitter window having a jitter window length. A transceiver of the UE uses radio resources for exchanging one or more video frames of the video application between the UE and a base station. The radio resources are determined by the UE based on one or more periodic-resources configurations. When the processing circuitry determines that data for a video frame, generated during one jitter window, was exchanged by use a periodic resource of one of the one or more periodic-resources configurations, the processing circuitry determines to prohibit the use of further periodic radio resources according to the one or more periodic-resources configurations for a period of time.
