Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G New Radio frame structure configurations lack flexibility in resource allocation, with static proportions of uplink and downlink resources limiting scalability and adaptability in different deployment scenarios.
Innovation Solution
A dual-periodicity or multi-periodicity frame structure configuration method that concatenates different periodicities and resource configurations in the time domain, allowing for the creation of new periodicities and enhancing resource configuration flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single periodicity frame structure configuration is used, then the system structure is simple and easy to manage, but the resource configuration flexibility and adaptability to different deployment scenarios are limited
Solution Approach 1:
The frame structure is segmented into multiple periodicity configurations (first periodicity and second periodicity), each with independent resource allocation patterns. This allows different time resources to be divided into different periodicities, enabling flexible adaptation to various deployment scenarios while maintaining manageable complexity through structured segmentation
Solution Approach 2:
The system dynamically selects between different periodicity configurations based on deployment requirements. The frame structure can switch between first periodicity patterns (with first proportion of uplink resources) and second periodicity patterns (with second proportion of uplink resources), providing adaptability without requiring complex reconfiguration mechanisms
2Stability of the object's composition
If static resource configurations with constant uplink-downlink proportions are used, then the configuration is simple and stable, but the resource allocation flexibility across different time periods is reduced
Solution Approach 1:
The system implements periodic resource allocation with different proportions in different periodicities. The first periodicity configuration and second periodicity configuration alternate or coexist, allowing the resource allocation to follow periodic patterns that adapt to different traffic demands while maintaining stability through structured periodicity
Solution Approach 2:
The uplink resource proportion parameter changes between different periodicity configurations. In the first periodicity, uplink resources occupy the first proportion, while in the second periodicity, uplink resources occupy the second proportion. This parameter variation enables flexible resource allocation while maintaining overall system stability

AI summary
A frame structure configuration method, a frame structure obtaining method, a base station and UE are provided. The frame structure configuration method includes transmitting at least two cell-specific frame structure configurations concatenated in a time domain to the UE. Different periodicities of cell-specific uplink and/or downlink resources that are concatenated in a time domain are supported, and/or different configurations for the uplink and/or downlink resources within periodicities concatenated in the time domain are supported. In some embodiments, the base station transmits at least two cell-specific frame structure configurations concatenated in a time domain to the UE, where two periodicities of cell-specific uplink and/or downlink resources that are concatenated in a time domain have different durations, and/or, the uplink and/or downlink resources within the two periodicities concatenated in the time domain have different configurations.
