Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single DCI schedules data for only one cell, then the scheduling mechanism is simple and reliable, but the payload overhead is high and system capacity is limited
Solution Approach 1:
The DCI is designed to perform multiple functions by scheduling data for multiple cells simultaneously. The single DCI structure includes multiple information fields that can each schedule different cells, making the DCI a multi-functional control message that serves multiple cells in one transmission, thereby improving system capacity without proportionally increasing complexity
Solution Approach 2:
The DCI is segmented into multiple information fields, where each information field corresponds to a specific cell scheduling task. This segmentation allows the single DCI to independently control multiple cells by dividing the scheduling function into separate field components, each handling one cell while maintaining overall system efficiency
2Quantity of substance
If multiple cells are scheduled through a single DCI, then payload overhead is reduced and system capacity is improved, but the complexity of determining scheduling information for each cell increases
Solution Approach 1:
The DCI is divided into multiple information fields, with each field dedicated to scheduling a specific cell. This segmentation allows the terminal to process scheduling information systematically by iterating through each field and its corresponding cell, reducing the complexity of determining scheduling information for multiple cells through a structured, field-by-field approach
Solution Approach 2:
The patent introduces a mapping relationship between information fields and cells, where the terminal determines scheduling information by changing the parameter of which information field corresponds to which cell. This parameter mapping approach simplifies the determination process by establishing a clear correspondence rule between fields and cells, making the complexity manageable through systematic parameter association

AI summary
A method, apparatus and computer readable medium for determining scheduling information in a wireless communication network. The scheduling information is determined by: receiving DCI sent by a network device and used for scheduling a plurality of cells; determining an association relationship between a plurality of information domains of the same type in the DCI and the plurality of cells; and determining scheduling information of each cell according to the value of each information domain and the association relationship. Therefore, on the basis of scheduling a plurality of cells by means of one DCI, scheduling information of each cell is accurately determined.
