Solution Overview
Problem
Current radio communication systems, particularly in the context of 5G and beyond, face challenges in efficiently managing frequency hopping for PUSCH (Physical Uplink Shared Channel) in LTE and NR (New Radio) systems, where the determination of hopping intervals and DMRS bundling configurations are not adequately addressed, impacting communication efficiency.
Innovation Solution
The implementation of a terminal apparatus and base station apparatus that manage higher layer parameters to enable frequency hopping for PUSCH based on DCI (Downlink Control Information), with specific parameters determining whether DMRS bundling is enabled and configuring time domain windows, thereby optimizing hopping intervals and improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If frequency hopping is applied for PUSCH based on DCI with multiple higher layer parameter configurations, then communication efficiency and resource allocation optimization are improved, but device complexity and parameter management complexity increase
Solution Approach 1:
The patent implements dynamic frequency hopping where the hopping interval is determined by the third higher layer parameter which can be dynamically configured. The system allows flexible switching between different hopping intervals (first interval or second interval) based on the parameter configuration, enabling adaptive resource allocation that optimizes communication efficiency while managing complexity through structured parameter management.
Solution Approach 2:
The patent utilizes multiple higher layer parameters (first, second, and third parameters) that can be independently configured to control different aspects of frequency hopping behavior. By changing these parameters, the system can adjust the hopping interval, DMRS bundling configuration, and time domain window settings to optimize performance for different communication scenarios without hardcoding complex logic.
2Adaptability or versatility
If multiple higher layer parameters are managed for frequency hopping configuration, then adaptability and resource allocation flexibility are improved, but ease of operation and configuration simplicity deteriorate
Solution Approach 1:
The patent segments the frequency hopping configuration into multiple independent higher layer parameters: the first parameter for DMRS bundling control, the second parameter for time domain window configuration, and the third parameter for hopping interval determination. This segmentation allows each parameter to be configured and managed independently, providing fine-grained control over different aspects of frequency hopping while maintaining operational simplicity through modular parameter management.
Solution Approach 2:
The higher layer parameters serve multiple functions: they control frequency hopping behavior, manage DMRS bundling, configure time domain windows, and determine hopping intervals. This multi-functionality reduces the need for separate configuration mechanisms for each feature, simplifying the overall configuration process while maintaining high adaptability for different communication scenarios.
