Serving Cell Time Conflict Determination for 5G Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems like 5G, terminals may face transmission conflicts due to conflicting time resources across multiple serving cells, leading to inefficiencies and misaligned resource utilization between the network and the terminal.
Innovation Solution
A method for determining conflicting time resources in a terminal's serving cells by analyzing activation information, such as states and command reception times of secondary cells, to identify and avoid conflicts, ensuring synchronized understanding between the network and terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal simultaneously accesses multiple serving cells with same time resources, then the transmission efficiency is improved, but transmission conflicts occur between cells
Solution Approach 1:
The terminal determines conflicting time resources in advance by comparing uplink time resources with downlink time resources across multiple serving cells before actual transmission occurs. This preliminary detection allows the terminal to identify and avoid conflicts proactively, ensuring reliable simultaneous access to multiple cells without transmission interference
2Device complexity
If the terminal determines conflicting resources without considering activation information, then the determination process is simplified, but the accuracy of conflict detection deteriorates
Solution Approach 1:
The terminal applies different determination rules to different serving cells based on their activation states. For deactivated cells, the terminal uses default time resource configurations, while for activated cells, the terminal uses actual configured time resources. This localized approach ensures accurate conflict detection without uniformly complicating the entire determination process
3Adaptability or versatility
If the network and terminal have different understanding of cell activation states, then resource allocation is more flexible, but resource utilization efficiency deteriorates due to misalignment
Solution Approach 1:
The terminal determines conflicting resources based on activation information that includes command reception times from the network. This feedback mechanism ensures both the network and terminal have synchronized understanding of which cells are activated and their time resource configurations, eliminating misalignment while preserving the flexibility of dynamic resource allocation
