Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of communication service operators increases, the size of the frequency bandwidth that RF chains in base stations must operate in increases, leading to increased component costs and power consumption, posing implementation challenges.
Innovation Solution
Implement a method of frequency using a DUC a switch matrix control unit in a base station to manage RF chains, allowing each to operate within the bandwidth of a single operator, reducing component costs and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RF chains are configured to support multiple operators with different frequency bands, then network sharing capability is improved, but component costs and power consumption increase
Solution Approach 1:
The patent applies dynamics by making the RF chain configuration flexible and changeable over time. The base station dynamically configures RF chains to match the frequency band requirements of currently served operators, rather than statically supporting all operators simultaneously. This allows the system to adapt its resource allocation to current needs, reducing power consumption when fewer operators are active.
Solution Approach 2:
The patent changes the operating parameters (frequency bands) of RF chains based on which operators are currently being served. The base station monitors operator presence and adjusts the frequency band parameters of active RF chains accordingly, enabling network sharing while avoiding the continuous operation of all RF chains across all frequency bands, thus reducing power consumption.
2Adaptability or versatility
If RF chains are configured to support multiple operators with different frequency bands, then network sharing capability is improved, but component costs increase
Solution Approach 1:
The patent implements universality by designing RF chains that can function across multiple frequency bands through dynamic reconfiguration. Instead of requiring separate dedicated RF chains for each operator and frequency band, a single RF chain can serve multiple operators by changing its operating parameters, reducing the total number of components needed and lowering manufacturing costs.
Solution Approach 2:
The dynamic reconfiguration capability allows existing RF chain hardware to serve multiple purposes and frequency bands, eliminating the need to manufacture and deploy separate hardware for each operator. This reduces component costs while maintaining network sharing capability.
3Adaptability or versatility
If RF chains operate across large frequency bandwidths to support multiple operators, then network sharing is enabled, but implementation difficulty increases
Solution Approach 1:
The patent applies segmentation by dividing the overall frequency spectrum into separate bands, each handled by dedicated RF chains. Rather than requiring a single complex RF chain to handle all frequency bands simultaneously, the system segments frequency resources and assigns them to appropriate RF chains, simplifying the implementation of each individual RF chain while enabling network sharing.
Solution Approach 2:
The base station monitors which operators are currently connected and adjusts the frequency band parameters of active RF chains to match only the required bands. This parameter adjustment approach simplifies implementation by ensuring RF chains operate within their optimal frequency ranges rather than attempting to handle the entire spectrum continuously.
