Time-Multiplexed Radio Resource Allocation for H2H and MTC Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile telecommunications systems inefficiently use radio resources when sharing them between human-to-human (H2H) and machine-type communication (MTC) data, leading to suboptimal utilization due to unsuitable allocation strategies and lack of consideration for the different characteristics of each data type.
Innovation Solution
Implementing a time-multiplexed approach where radio resources are allocated differently based on the type of data, with MTC data transmission restricted during peak H2H activity periods and vice versa, using specific sub-periods and carriers to manage traffic and prevent network overload, allowing for flexible adjustment based on network conditions.

Engineering Contradiction Analysis
1Productivity
If radio resources are shared between H2H and MTC devices using conventional allocation strategies, then both types of communication can operate simultaneously, but radio resource utilization becomes inefficient due to conflicting allocation needs
Solution Approach 1:
The patent implements dynamic time-multiplexed allocation where radio resources are switched between H2H and MTC devices based on varying network conditions and traffic patterns. The system transitions from static allocation to dynamic allocation, adjusting resource distribution in real-time to optimize utilization efficiency while adapting to different communication requirements.
Solution Approach 2:
The patent employs periodic time-multiplexed cycles where radio resources are alternately allocated to H2H devices during first time periods and to MTC devices during second time periods. This periodic switching pattern enables systematic resource sharing, improving overall utilization while accommodating the distinct characteristics of each communication type through structured temporal separation.
2Productivity
If radio resources are allocated to MTC devices during peak H2H activity periods, then MTC data transmission capacity increases, but H2H communication quality deteriorates due to resource contention
Solution Approach 1:
The patent segments the radio resource allocation timeline into distinct time periods: first time periods dedicated to H2H devices and second time periods dedicated to MTC devices. This temporal segmentation prevents resource contention by ensuring that MTC transmissions occur only when H2H devices are not actively utilizing resources, thereby maintaining H2H communication quality while enabling MTC capacity.
Solution Approach 2:
The system implements periodic alternation between H2H-dedicated periods and MTC-dedicated periods. During second time periods, radio resources are allocated to MTC devices to maximize their transmission capacity, while H2H communication quality is preserved because resources are not contended during their dedicated first time periods. This periodic scheduling resolves the contradiction through structured temporal separation.
3Productivity
If radio resources are restricted for H2H devices outside specified periods, then MTC devices gain sufficient resources for data transmission, but overall network flexibility decreases
Solution Approach 1:
The patent implements dynamic resource restriction and release mechanisms where H2H device access to radio resources is temporarily restricted during second time periods to ensure MTC devices receive sufficient resources. The system dynamically adjusts allocation based on the current time period, maintaining network flexibility through programmable control that can adapt restrictions to varying network conditions and traffic patterns.
Solution Approach 2:
The system applies periodic restriction patterns where H2H devices are restricted from accessing radio resources during second time periods, enabling MTC devices to utilize full resource capacity for data transmission. During first time periods, restrictions are lifted and resources are released for H2H use. This periodic restriction-release cycle maintains overall network flexibility while ensuring adequate resources for MTC operations.
