Wireless Communication Capability Reporting for SCS-Aware Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, existing methods lack efficiency in scheduling resources for terminals with different processing capabilities at various subcarrier spacings (SCS), leading to abnormal data processing and reduced reliability of data transmission.
Innovation Solution
A wireless communication method where terminals report their capability information indicating processing capabilities at different SCS, allowing base stations to schedule resources accordingly, thereby optimizing resource allocation based on terminal capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station schedules one or more PDSCHs or PUSCHs in one time slot for terminals with different capabilities, then the resource utilization is improved, but the reliability of data transmission deteriorates due to abnormal data processing
Solution Approach 1:
The patent applies parameter changes by introducing terminal capability parameters that indicate the maximum number of PDSCHs or PUSCHs the terminal can process in one time slot. The base station uses these parameters to adjust scheduling decisions, matching the scheduled channel count to the terminal's processing capability. This resolves the contradiction by enabling high resource utilization through parallel scheduling while maintaining reliability by ensuring the scheduled count does not exceed terminal capabilities.
2Device complexity
If the base station uses unified scheduling parameters for all terminals, then the scheduling complexity is reduced, but the efficiency of resource scheduling deteriorates
Solution Approach 1:
The patent applies preliminary action by having terminals report their capability information (maximum number of PDSCHs/PUSCHs processable in one time slot) to the base station before scheduling occurs. The base station stores these capability parameters and uses them for subsequent scheduling decisions. This resolves the contradiction by preparing terminal capability data in advance, enabling efficient differentiated scheduling without increasing operational complexity during the scheduling process.
