Wireless Device Pre-Allocated Radio Resource Timing Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Industrial IoT (IIoT) wireless communication systems, the inefficiency of radio resource usage and increased overhead in monitoring processes occur due to the allocation of pre-configured radio resources for periodic deterministic traffic, which are not utilized for aperiodic deterministic traffic, leading to reduced efficiency and increased control signal monitoring overhead.
Innovation Solution
A wireless communication system that adjusts the timing of pre-allocated radio resources to a predetermined different timing, allowing for the transmission of aperiodic deterministic traffic without requiring new allocation processes, thereby avoiding the allocation of multiple pre-allocated radio resources and reducing processing overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pre-configured radio resources are allocated for periodic deterministic traffic, then the efficiency of radio resource usage is improved for periodic traffic, but the overhead in control signal monitoring process increases and radio resources are wasted for aperiodic deterministic traffic
Solution Approach 1:
The patent applies dynamics by making the radio resource allocation flexible rather than static. The pre-configured radio resources can be dynamically adjusted in timing to accommodate either periodic deterministic traffic or aperiodic deterministic traffic. This allows the system to adapt resource allocation based on traffic type without requiring separate allocation processes, thereby reducing control signal monitoring overhead while maintaining efficient resource utilization.
2Adaptability or versatility
If multiple pre-allocated radio resources are allocated for aperiodic deterministic traffic, then the transmission capability for aperiodic traffic is improved, but the overhead in allocation process and control signal monitoring increases
Solution Approach 1:
The patent implements universality by designing pre-configured radio resources that can serve multiple purposes - handling both periodic deterministic traffic and aperiodic deterministic traffic. By adjusting the timing of existing pre-configured resources rather than creating separate allocation mechanisms for aperiodic traffic, the system achieves versatile transmission capability while avoiding the overhead associated with multiple allocation processes.
