Base Station PCC Release for Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular radio telecommunications, the automatic selection of a primary component carrier (PCC) by new base stations can lead to sub-optimal resource allocation and interference, reducing the maximum capacity of neighboring base stations and overall system performance.
Innovation Solution
A method is implemented where each base station evaluates its capacity and that of neighboring stations, releasing its PCC and entering a stand-by mode if it determines that its presence degrades system performance, thereby reducing interference and optimizing resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a new base station automatically selects and occupies a primary component carrier (PCC), then the base station can provide wireless communication services, but interference increases and the maximum capacity of neighboring base stations is reduced
Solution Approach 1:
The base station continuously monitors system performance metrics including interference levels and capacity utilization. When the base station detects that its presence degrades overall system performance, it automatically releases the PCC and transitions to stand-by mode, creating a feedback loop that optimizes system capacity while maintaining operational flexibility
Solution Approach 2:
The base station dynamically transitions between operational modes (active and stand-by) based on real-time system conditions. This dynamic adaptation allows the network to optimize resource allocation by having base stations enter stand-by mode when they would cause excessive interference, thereby improving overall system productivity
2Reliability
If a base station remains continuously operational, then it can serve user equipment, but interference increases and resource utilization becomes sub-optimal
Solution Approach 1:
The base station periodically evaluates system performance metrics and transitions between active and stand-by modes based on these evaluations. This periodic assessment ensures that the base station remains operational when needed while minimizing interference by entering stand-by mode when system performance would be degraded, thus balancing service availability with interference reduction
3Area of stationary object
If base stations are deployed densely to increase coverage, then more areas are covered, but interference increases and maximum capacity of individual stations decreases
Solution Approach 1:
Each base station autonomously monitors system-wide interference levels and capacity metrics, making independent decisions about whether to remain operational or transition to stand-by mode. This self-service mechanism allows densely deployed base stations to automatically adjust their operational status, maintaining broad coverage while preventing any single station from degrading overall system capacity through excessive interference

AI summary
The present invention relates to optimized radio resource utilization in a cellular telecommunication system. A base station of such a system evaluate a capacity metric of the base station and capacity metrics of neighboring base stations. In response to detecting that the capacity metric of the base station is below a threshold with respect to the capacity metrics of the neighboring base stations, the base station enters a stand-by mode and releases its radio resources that essentially define a cell associated with the base station so that the released radio resources become available for allocation to at least one of the neighboring base stations.
