Solution Overview
Problem
Current methods for configuring the frame structure in 5G communication systems, specifically the time interval X, have not been realized, preventing normal communication between network and user equipment.
Innovation Solution
A method is provided to configure a group of time intervals X by generating configuration information based on channel conditions and communication service demands, which is added to downlink control information and transmitted to user equipment, enabling data transmission according to the configured intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a method for indicating configuration of frame structure including time interval X is not realized, then the frame structure cannot be properly configured, but normal communication between network and user equipment cannot be achieved
Solution Approach 1:
The frame structure configuration is segmented into multiple time intervals X, where each interval can be independently configured and indicated to the UE. This allows the network to divide the overall frame structure into manageable segments that can be flexibly adjusted based on communication needs, resolving the contradiction between configuration reliability and complexity.
Solution Approach 2:
The frame structure configuration is made dynamic through the introduction of time interval X, which can be flexibly adjusted and reconfigured based on channel conditions and communication service demands. This dynamic approach enables the system to adapt to changing requirements while maintaining reliable communication, addressing the contradiction between reliability and configuration complexity.
2Adaptability or versatility
If time interval X is introduced with multiple types (type 1, type 2, type 3), then frame structure flexibility is improved, but configuration and indication complexity increases
Solution Approach 1:
Different types of time intervals X are defined by changing key parameters such as the presence and duration of Guard Periods, downlink transmission parts, and uplink transmission parts. This parameter-based differentiation allows flexible frame structure adaptation while maintaining a unified configuration indication mechanism, resolving the contradiction between adaptability and configuration complexity.
Solution Approach 2:
The time interval X structure serves multiple functions depending on its type: it can provide downlink-to-uplink switching (type 3), support self-contained structures for low latency (type 2), or offer flexible resource allocation (type 1). This multi-functionality within a single configurable framework enables frame structure adaptability without proportionally increasing configuration complexity.
3Loss of information
If configuration information of time interval X is added to downlink control information, then indication capability is improved, but downlink control information overhead increases
Solution Approach 1:
Instead of indicating all frame structure parameters, the patent selectively indicates only the essential configuration information of time interval X in the downlink control information. This partial indication approach provides sufficient configuration completeness for UE operation while minimizing the increase in downlink control information overhead, resolving the contradiction between indication completeness and information volume.

AI summary
Method for configuring frame structure, user equipment and network equipment are provided. The method includes: configuring a group of time intervals X and generating configuration information of the group of time intervals X according to a channel condition and communication service demand; adding the configuration information of the group of time intervals X to downlink control information which is carried in a predetermined resource unit; and transmitting the predetermined resource unit to a UE, to indicate the UE to perform data transmission with a network based on the group of time intervals X. In this way, the configuration of the frame structure including the time intervals X is indicated, so that the network and the UE can normally communicate with each other.
