Location-Based Frequency Domain Resource Allocation for Wireless Interference Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in mitigating interference in protected zones, particularly where devices operating in different frequency bands, such as ITS and DSRC, coexist, leading to potential performance degradation due to close frequency operations.
Innovation Solution
Implementing location-based frequency domain resource allocation, where devices within protected zones use a full available frequency domain resource allocation to minimize interference, thereby operating in less restrictive coexistence modes and maintaining higher transmit power levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices operate in different frequency bands (ITS and DSRC) in protected zones, then communication flexibility is improved, but interference between systems increases
Solution Approach 1:
The frequency domain resources are segmented into different allocation schemes based on location. Devices in protected zones use one allocation scheme (full available frequency domain resources), while devices outside use another scheme, thereby separating the operational modes to avoid interference
Solution Approach 2:
Different frequency domain resource allocation strategies are applied to different geographic locations. Protected zones receive specialized allocation treatment to minimize interference, while other areas use standard allocation, making the system adapt to local interference conditions
2Power
If devices use full available frequency domain resource allocation in protected zones, then transmit power can be maintained at higher levels, but frequency resource efficiency decreases
Solution Approach 1:
The frequency domain resource allocation is made dynamic based on device location. The system transitions between different allocation modes (full available resources vs. other allocations) depending on whether the device is in a protected zone, allowing optimal power and resource efficiency trade-offs for each location
3Object-generated harmful factors
If location-based resource allocation is implemented, then interference mitigation is improved, but system complexity increases
Solution Approach 1:
Devices autonomously determine their own location relative to protected zones and self-adjust their frequency domain resource allocation accordingly. This self-service approach eliminates the need for complex centralized control and coordination, reducing overall system complexity while achieving interference mitigation
