Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If baseband data are stored according to a time sequence of radio frames without classification, then the storage structure is simple, but data access efficiency deteriorates and cannot meet flexible scheduling requirements
Solution Approach 1:
The patent segments baseband data storage by classifying data according to cell attributes (bandwidth and antenna quantity) into different cell sets, each with dedicated random storage regions. This segmentation enables efficient data access for flexible scheduling while maintaining organized storage structure through attribute-based classification.
2Quantity of substance
If storage space is not multiplexed by antennas and memory quantity is increased in equal proportion to antenna increasement, then data storage capacity is sufficient, but hardware resource waste occurs
Solution Approach 1:
The patent merges storage resources by allowing multiple cell sets to share random storage regions. Cell sets with different antenna configurations can multiplex the same physical memory resources, reducing hardware consumption while maintaining sufficient storage capacity through virtualization of storage space.
Solution Approach 2:
The patent creates universal random storage regions that can serve multiple cell sets with different antenna configurations. The same storage region can be dynamically allocated to different cell sets based on their bandwidth and antenna requirements, making the storage system multi-functional and resource-efficient.
3Adaptability or versatility
If baseband data are classified and stored according to cell attributes (bandwidth and antenna quantity), then data access flexibility improves, but storage control complexity increases
Solution Approach 1:
The patent performs preliminary classification of cell sets based on bandwidth and antenna quantity attributes before data storage. By pre-defining cell sets and their corresponding random storage regions, the system achieves flexible data access without requiring complex runtime classification logic, thus managing storage control complexity effectively.
