Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized baseband data switch is used to implement baseband pool function, then the baseband resources can be dynamically allocated to any RRU, but the device complexity and cost increase due to requiring a large switch matrix
Solution Approach 1:
The patent divides the centralized baseband data switch into multiple distributed baseband processing units, each equipped with a small-capacity switch module. This segmentation eliminates the need for a large centralized switch matrix while maintaining the ability to dynamically allocate baseband resources across RRUs through distributed switching cooperation.
2Quantity of substance
If a large switch matrix is used in centralized baseband data switch, then the maximum capacity is increased, but the reliability decreases because the centralized switch becomes a single point of failure
Solution Approach 1:
By segmenting the centralized switch into multiple distributed switching units embedded in separate baseband processing units, the patent eliminates the single point of failure. Each unit can independently operate, and the system can tolerate failures in individual units while maintaining overall functionality through distributed switching coordination.
Solution Approach 2:
The patent changes the architectural parameter from centralized to distributed switching, transforming the system from having one large switch matrix to multiple small switch matrices distributed across processing units. This parameter change simultaneously increases capacity through parallel processing and improves reliability through redundancy.
3Quantity of substance
If a centralized baseband data switch with large capacity is deployed, then the maximum switch capacity is achieved, but the cost increases due to configuring large switch function modules
Solution Approach 1:
The patent segments the large switch capacity requirement into multiple small-capacity switch modules distributed across baseband processing units. This approach reduces the cost of individual switch modules while achieving the same total switching capacity through parallel distributed switching, making the system more cost-effective.
Solution Approach 2:
By using multiple inexpensive small-capacity switch modules instead of one expensive large-capacity switch module, the patent reduces the overall system cost. The distributed architecture allows using cheaper components that can be replicated across multiple units to achieve the required total capacity.

AI summary
A baseband pool device includes a control unit, and a plurality of baseband processing units which are connected one another. The control unit is configured to determine one or more baseband processing units participating in data processing according to a size of data received by the baseband pool device and baseband data processing capabilities of various baseband processing unit, and allocate an identifier of the baseband data to be processed to each baseband processing unit participating in the data processing to construct a data allocation relationship, and respectively transmit the data allocation relationship to the baseband processing units participating in the data processing. The baseband processing units receive the data allocation relationship; and, process the received data according to the data allocation relationship, or transmit the received data to other baseband processing units of the baseband pool device, or receive data processed and then forwarded by other baseband processing units. A method for implementing baseband data distributed switch is also provided. The present invention increases the baseband processing capacity and reduces the cost.
