SBFD Resource Configuration for Asymmetric Traffic Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resource configuration methods for flexible/full duplex (SBFD) patterns are static and do not dynamically adjust to asymmetric uplink and downlink traffic, leading to suboptimal resource utilization.
Innovation Solution
A method and apparatus for dynamically signaling whether a sub-band full duplex (SBFD) pattern takes effect, allowing terminals to adjust resource availability based on real-time traffic conditions, using dynamic signaling to enhance resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a semi-static SBFD pattern is configured for uplink and downlink resources, then resource allocation is simplified and device complexity is reduced, but resource utilization becomes suboptimal when traffic is asymmetric
Solution Approach 1:
The patent introduces dynamic indication information that allows the network device to dynamically adjust whether the semi-static SBFD pattern takes effect for specific time-domain units. This dynamic mechanism enables the system to adapt to varying traffic conditions without requiring complex real-time resource configuration, thus resolving the contradiction between simplicity and efficiency.
Solution Approach 2:
The patent changes the state parameter of the SBFD pattern from fixed to configurable through dynamic indication information. By controlling whether the pattern takes effect or not based on traffic conditions, the system can optimize resource utilization while maintaining the simplicity of semi-static configuration when conditions permit.
2Productivity
If dynamic signaling is introduced to indicate SBFD pattern effectiveness, then resource utilization improves by matching traffic conditions, but signaling overhead and system complexity increase
Solution Approach 1:
The patent applies dynamic indication selectively rather than continuously. The network device sends dynamic indication information only when needed to adjust SBFD pattern effectiveness, avoiding unnecessary signaling overhead while still capturing the benefits of dynamic adaptation for resource utilization.
Solution Approach 2:
The patent modifies the operational state of the SBFD pattern through dynamic indication information, enabling the system to transition between static and dynamic operation modes. This parameter change approach allows the system to achieve improved resource utilization without permanently increasing system complexity.
