Channel Selector Switch State Management for RF Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual connectivity scenarios, when one RF channel enters a dormant state, it affects the communication quality of another RF channel sharing a channel selector switch, leading to reduced throughput and poor communication performance.
Innovation Solution
A method and device that determine the state of each RF channel and maintain an active state of the channel selector switch when one RF channel enters a dormant state while the other is activated, ensuring continuous communication quality by preventing the channel selector switch from entering a dormant state, thereby maintaining a workable RF path for the active channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the channel selector switch enters a dormant state to save power when one RF channel is dormant, then power consumption is reduced, but the communication quality of the other RF channel deteriorates
Solution Approach 1:
The patent implements dynamic state management of the channel selector switch by continuously monitoring the operational states of multiple RF channels. The switch transitions between active and dormant states based on real-time channel conditions, allowing the system to optimize power consumption while ensuring that when one channel becomes active, the switch is promptly activated to maintain communication quality. This dynamic adaptation resolves the contradiction between power savings and communication reliability.
Solution Approach 2:
The system employs feedback mechanisms by monitoring the state of each RF channel and using this information to control the channel selector switch. When a dormant channel transitions to an active state, the feedback signal triggers the channel selector switch to activate, thereby maintaining communication quality. This feedback loop ensures that power is saved during dormant periods while communication performance is preserved when channels are in use.
2Reliability
If the channel selector switch is kept in active state to maintain communication quality, then communication performance is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic monitoring of RF channel states and corresponding periodic activation/deactivation of the channel selector switch. Instead of maintaining continuous active state, the system periodically checks channel conditions and activates the switch only when necessary. This periodic action pattern reduces overall power consumption while ensuring communication quality is maintained during active periods, resolving the contradiction between sustained performance and energy usage.
Solution Approach 2:
The system discards the active state of the channel selector switch during periods when all RF channels are dormant, and recovers (reactivates) the switch when a channel transitions to active state. This cycle of discarding and recovering the active state allows the system to minimize power consumption during idle periods while ensuring rapid restoration of communication capability when needed, thereby balancing power usage and communication quality.

AI summary
A method and a device for controlling a channel selector switch and a storage medium are provided. The method for controlling the channel selector switch is applied to a terminal having at least two radio frequency channels; and the at least two radio frequency channels share the channel selector switch. The method includes: determining a state of each of a first RF channel and a second RF channel that share a same channel selector switch; and maintaining, in response to that the first RF channel is to enter a dormant state and the second RF channel is in an activated state, an active state of the channel selector switch.
