Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam sweeping uses fixed slot structure with p×N symbols, then synchronization signal transmission is completed, but remaining y-(p×N)%y symbols become idle resources that cannot be effectively used
Solution Approach 1:
The patent divides the slot structure into two parts: a fixed portion for synchronization signal block transmission (p×N symbols) and a remaining portion (y-(p×N)%y symbols). By segmenting the slot, the invention enables the remaining symbols to be independently utilized for other purposes such as transmitting downlink control information, thereby resolving the resource waste problem while maintaining reliable synchronization signal transmission.
Solution Approach 2:
The patent makes the slot structure multi-functional by allowing the remaining symbols after synchronization signal transmission to serve multiple purposes. These symbols can be used for downlink control information transmission, mini-slot data transmission, or other communication functions, transforming idle resources into valuable multi-purpose resources that improve overall system efficiency.
2Ease of operation
If remaining symbols are left idle after synchronization signal block transmission, then transmission timing is simplified, but resource utilization deteriorates with wasted remaining resources
Solution Approach 1:
The patent applies preliminary action by pre-defining the structure and usage of remaining symbols in the slot. The system预先 determines that remaining symbols will be used for specific purposes such as downlink control information or mini-slot transmission, eliminating the need for complex real-time decisions about resource allocation while maximizing resource utilization.
3Adaptability or versatility
If user equipment is scheduled only in fixed slot units, then scheduling is simple and standardized, but flexibility to utilize remaining resources is lost
Solution Approach 1:
The patent segments the traditional slot-based scheduling into slot-level scheduling and mini-slot-level scheduling. This segmentation allows the system to maintain simple fixed-slot scheduling for常规 traffic while introducing flexible mini-slot scheduling within remaining symbols for urgent or variable traffic, thereby increasing adaptability without significantly complicating the overall scheduling structure.
Solution Approach 2:
The patent introduces dynamic scheduling capability by allowing the system to adaptively allocate remaining symbols based on actual traffic needs. The scheduling structure becomes dynamic as it can switch between using remaining symbols for control information, mini-slot data transmission, or other purposes depending on system conditions, enhancing versatility while maintaining manageable complexity.
Data Source
AI summary
A method and a device for scheduling and using remaining resources of a synchronization signal block is described. The method includes configuring a mini-slot according to the remaining resources, and transmitting scheduling information for the mini-slot to a user equipment. The method further includes scheduling information that includes downlink control information for the mini-slot. Further, the remaining resources include remaining symbols left after occupation of the last synchronization signal block in a slot where the last synchronization signal block is located, when at least one synchronization signal block is transmitted.
