Microwave Data Slicing for Differentiated Latency and Bandwidth
Solution Overview
Problem
Conventional microwave air interfaces cannot meet the diverse latency and bandwidth requirements of different applications in 5G scenarios, as they treat all data streams uniformly, leading to inadequate transmission performance.
Innovation Solution
The method involves slicing microwave data streams into logical slices, configuring independent air interface resources based on slice types, and encoding these slices to meet specific transmission requirements, using techniques like RS encoding and LDPC encoding to generate encoded data with tailored performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a unified air interface resource is used for all data streams, then the system structure is simple and easy to manage, but the data transmission cannot meet differentiated latency and bandwidth requirements of different applications
Solution Approach 1:
The patent applies segmentation by dividing the unified air interface resource into multiple logical air interface resources based on different service types (e.g., eMBB, uRLLC, mMTC). Each logical resource is independently managed and allocated to corresponding service data streams, enabling differentiated transmission parameters such as latency and bandwidth to meet diverse application requirements while maintaining systematic organization through logical classification.
2Productivity
If data streams are transmitted with unified scheduling rules, then the scheduling mechanism is simple, but the transmission latency and bandwidth cannot be optimized for different service types
Solution Approach 1:
The patent implements local quality by establishing different scheduling rules and transmission parameters for different logical air interface resources according to their specific service requirements. For example, uRLLC services receive scheduling with stricter latency constraints and higher priority, while eMBB services use scheduling optimized for bandwidth efficiency. This allows each service type to operate under locally optimized conditions rather than a single unified scheduling policy.
3Reliability
If all data streams share the same air interface resource, then the resource allocation is simple and manageable, but the transmission reliability cannot be ensured for services with different reliability requirements
Solution Approach 1:
The patent segments the air interface resource into multiple logical resources with different allocation strategies tailored to specific service reliability requirements. Critical services like uRLLC are allocated dedicated logical resources with guaranteed transmission parameters and higher priority scheduling, while less critical services share resources with more flexible allocation. This segmentation ensures that reliability-critical transmissions are protected from interference and resource contention.
Solution Approach 2:
The patent applies parameter changes by adjusting transmission parameters such as modulation schemes, coding rates, and resource block allocations differently across logical air interface resources based on service requirements. For high-reliability services, more robust parameters (lower order modulation, higher coding rates) are used, while for bandwidth-intensive services, more efficient parameters are applied. This dynamic parameter adjustment optimizes transmission reliability for each service type.

AI summary
Embodiments of the present invention disclose a microwave data processing method and apparatus, and a device. A logical slice is obtained by slicing a microwave data stream, and an independent air interface resource is allocated to the logical slice, so that different logical slices are independent of each other, and then different logical slices are correspondingly encoded, so that encoded data that meets different transmission requirements is generated for different types of logical slices, thereby improving reliability of microwave data transmission, and increasing application scenarios of microwave data transmission.
