5G Control Channel Description List for Flexible QoS Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LTE technology's control channel design is inflexible and lacks scalability, making it inadequate for the diverse Quality of Service (QoS) requirements of 5G systems. This leads to reduced system spectrum efficiency and increased maintenance costs.
Innovation Solution
A method and system for designing a control channel description list in a 5G system, which includes configuration information for multiple types of control channels. This list is sent from a first communication node to a second communication node, enabling flexible configuration of control channels based on service requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LTE technology uses a single control channel design, then the system structure is simple, but the adaptability to diverse QoS requirements is poor
Solution Approach 1:
The control channel design is segmented into multiple types (first type, second type, third type) with different configurations. Each control channel type can be independently selected and configured based on specific QoS requirements, allowing the system to adapt to diverse service needs without requiring a complete redesign of the control channel structure.
Solution Approach 2:
The control channel configuration is made dynamic through the introduction of indication information that specifies which control channel type to use. This allows the system to flexibly switch between different control channel configurations based on real-time QoS requirements, transforming the static control channel design into a dynamic, adaptable system.
2Adaptability or versatility
If LTE technology uses dynamic scheduling for each sub-frame, then the system can support different control channels, but the design flexibility remains poor
Solution Approach 1:
The control channel design achieves universality by creating a multi-functional control channel structure where a single control channel can serve multiple QoS requirements through different configurations. The indication information mechanism allows one control channel to be adaptively configured for various service types, eliminating the need for separate dedicated control channels for each service.
3Adaptability or versatility
If terminal devices perform blind detection to determine service support, then the system can support multiple services, but power consumption and control overhead increase
Solution Approach 1:
The system performs preliminary action by pre-configuring multiple control channel types with different QoS parameters before actual service execution. The terminal device receives indication information that directly specifies which control channel type to use, eliminating the need for blind detection and reducing power consumption while maintaining multi-service support capability.
