Wireless Repeater Resource Block Muting for Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased noise and interference caused by wireless repeaters in data communication systems lead to higher uplink transmission power requirements for user equipment (UEs), which negatively impacts battery life and user experience.
Innovation Solution
A method where a wireless access point monitors the average uplink transmission power of UEs and determines resource block restrictions for wireless repeaters, reducing the overall transmission power needed by disabling or enabling LTE channels or resource blocks as necessary, thereby reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wireless repeaters are deployed to extend network coverage, then the wireless footprint is extended, but noise and interference increase causing UEs to require higher transmission power
Solution Approach 1:
The patent segments the frequency spectrum into resource blocks and selectively mutes specific resource blocks in wireless repeaters. This segmentation allows the system to maintain network coverage extension while reducing interference in specific frequency portions, thereby resolving the contradiction between extended footprint and reduced noise.
Solution Approach 2:
The patent applies local quality by implementing resource block muting selectively in specific frequency resources rather than uniformly across all frequencies. This allows certain resource blocks to be muted in repeaters to reduce interference, while other resource blocks remain active to maintain coverage, thus addressing both aspects of the contradiction.
2Reliability
If UEs increase transmission power to overcome noise and interference, then communication reliability is maintained, but battery life deteriorates
Solution Approach 1:
The patent applies preliminary anti-action by proactively muting specific resource blocks in wireless repeaters before interference can significantly degrade signal quality. This preemptive measure reduces the need for UEs to increase transmission power, thereby maintaining communication reliability while preserving battery life.
Solution Approach 2:
The patent implements feedback mechanisms where the network monitors interference levels and transmission power requirements, then dynamically adjusts resource block muting configurations in repeaters. This feedback loop ensures communication reliability is maintained while optimizing energy consumption by reducing UE transmission power when possible.
3Object-affected harmful factors
If resource block muting is applied in wireless repeaters, then interference is reduced, but network coverage capability may be compromised
Solution Approach 1:
The patent segments the frequency spectrum into multiple resource blocks and selectively mutes only specific portions rather than applying uniform muting across all frequencies. This segmentation allows the network to reduce interference in muted resource blocks while maintaining coverage capability through non-muted resource blocks, thus resolving the contradiction between interference reduction and coverage preservation.
Solution Approach 2:
The patent implements dynamic resource block muting where the configuration of muted resource blocks can be adjusted based on network conditions, traffic patterns, and interference measurements. This dynamic approach allows the system to optimize the balance between interference reduction and coverage maintenance by adapting muting patterns to current operational requirements.
Data Source
AI summary
A wireless communication system restricts resource block usage in wireless repeaters. The wireless communication system includes a wireless access point configured to transfer user data for User Equipment (UEs) wherein some of the UEs are connected to the wireless repeaters. The wireless access point is further configured to determine an average uplink transmission power for the UEs, and if the average uplink transmission power for the UEs exceeds an uplink transmission power threshold, then the wireless access point is configured to determine resource block restrictions for the wireless repeaters. The wireless access point is also configured to transfer the resource block restrictions for delivery to the wireless repeaters.
