Dynamic Resource Unit Configuration for 5G Interference Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 5G wireless communication system faces challenges in adapting to rapid changes in data traffic and interference issues due to limited flexibility in uplink and downlink proportions, especially in high-frequency bands, which affects system capability and coverage.
Innovation Solution
The system employs a method to dynamically configure resource units in frequency and time, allowing for multiple uplink and downlink proportions and the insertion of protection resource units to mitigate interference, enabling flexible adaptation to traffic changes and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the 5G system uses the same uplink and downlink proportion design as the LTE TDD system, then the system can maintain simplicity in configuration, but it brings great constraints and possible waste, and reduces system capability
Solution Approach 1:
The patent divides the carrier into multiple resource units in frequency and time, allowing different uplink and downlink proportions in different regions. This segmentation enables flexible adaptation to varying traffic patterns while maintaining manageable configuration through standardized resource unit definitions.
Solution Approach 2:
The patent introduces different uplink and downlink proportions for different regions within the same carrier based on local traffic characteristics. Each region can be configured with appropriate proportions, allowing the system to adapt to local requirements without affecting the entire carrier.
2Adaptability or versatility
If different uplink and downlink proportions are used in the same TDD carrier, then the system can adapt to rapid changes in data traffic, but uplink and downlink subframes indicated by the same subframe number may bring strong interference
Solution Approach 1:
The patent segments the carrier into multiple resource units with different uplink and downlink proportions for different regions. This allows traffic adaptation in each region independently while avoiding interference by confining different proportions to separate spatial regions.
Solution Approach 2:
The patent introduces protection resource units as intermediaries between resource units with different uplink and downlink proportions. These protection units act as buffers that prevent strong interference between adjacent resource units with conflicting proportions.
3Power
If the cell coverage range is reduced due to high frequency band deployment, then the system can achieve higher frequency utilization, but the number of users per cell is reduced and data traffic changes more rapidly
Solution Approach 1:
The patent enables dynamic configuration of uplink and downlink proportions in different resource units based on real-time traffic changes. This dynamic adaptation allows the system to respond to rapid traffic variations caused by reduced cell coverage in high frequency bands.
Solution Approach 2:
The patent changes the uplink and downlink proportion parameters in different resource units to adapt to varying traffic patterns. This parameter adjustment enables the system to optimize performance despite the reduced coverage range and faster traffic changes in high frequency bands.
