Terminal ICS Signaling for Full-Duplex Scheduling Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in full-duplex communication systems is the interference between uplink and downlink transmissions, which affects spectrum utilization efficiency and service latency, particularly due to the in-channel selectivity capability of terminals.
Innovation Solution
Terminals transmit information related to their in-channel selectivity capability to the network device, enabling the network to perform more appropriate scheduling and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If full-duplex technology is implemented to improve spectrum utilization efficiency and reduce service latency, then communication performance is improved, but interference between uplink and downlink transmissions increases
Solution Approach 1:
The patent applies local quality by enabling terminals with different in-channel selectivity capabilities to be treated differently in the scheduling process. The network device identifies terminals with high ICS capability and allocates full-duplex resources preferentially to them, while maintaining traditional scheduling for terminals with low ICS capability. This localized differentiation resolves the contradiction by allowing full-duplex operation in specific local contexts (high-ICS terminals) without compromising overall system stability.
Solution Approach 2:
The patent changes the scheduling parameter based on the terminal's ICS capability parameter. By introducing ICS capability as a new scheduling parameter and adjusting resource allocation strategies accordingly, the system can optimize for both full-duplex performance and interference management. Terminals with high ICS capability values are assigned full-duplex resources, effectively using parameter changes to resolve the interference issue while maintaining productivity gains.
2Loss of time
If full-duplex technology is implemented to reduce service latency, then communication speed is improved, but interference between simultaneous transmissions increases
Solution Approach 1:
The patent applies local quality by creating differentiated scheduling zones based on terminal capability. High-ICS terminals receive full-duplex scheduling that enables simultaneous uplink and downlink transmission, reducing latency for these specific terminals. Low-ICS terminals continue with traditional scheduling, preventing them from experiencing interference-related performance degradation. This localized approach reduces service latency where possible without allowing interference to worsen system-wide.
Solution Approach 2:
The patent introduces ICS capability information as an intermediary parameter that mediates between the conflicting goals of reducing latency and preventing interference. The network device uses this intermediary information to make intelligent scheduling decisions, selecting full-duplex mode for high-ICS terminals (reducing latency) while avoiding it for low-ICS terminals (preventing interference). This intermediary enables the system to balance both competing objectives.
