Communication Device Power Switching Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for appropriate control of variations in communication operations in communication apparatuses that perform relaying, particularly in managing switching periods for transmission power and beam changes.
Innovation Solution
A communication apparatus with a control section that configures a specific period before a first period where the transmission power is used, and switches the transmission power to the first power, along with a communication section that transmits signals accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If transmission power is switched to first power without configuring a specific period beforehand, then the communication operation can change quickly, but inconsistencies in power recognition occur between the communication apparatus and base station
Solution Approach 1:
The control section configures a specific period before the first period in which the first power is used. This preliminary configuration ensures that both the communication apparatus and base station have advance knowledge of the power switching timing, allowing them to synchronize their power recognition without delays or inconsistencies, thus resolving the contradiction between fast switching and reliable recognition
2Reliability
If a specific period is configured before power switching, then power recognition consistency is improved, but the communication operation response time increases
Solution Approach 1:
The specific period is configured in advance but does not extend the actual power switching duration. The configuration happens before the first period, allowing the system to prepare for switching without adding delay to the critical power transition moment, thus maintaining both reliability and responsiveness
3Device complexity
If transmission power is switched without preliminary configuration, then the system operates with simpler control procedures, but beam recognition inconsistencies occur between communication apparatus and terminal
Solution Approach 1:
The control section configures the specific period before the first period in advance, ensuring that both the communication apparatus and terminal have synchronized knowledge of when beam switching will occur. This preliminary configuration establishes a reliable timing reference that eliminates recognition inconsistencies while adding minimal complexity to the control procedure

AI summary
This communication device comprises: a control unit that, when switching transmission power for a communication operation executed by the communication device between a base station and a terminal to first power, sets a specific period before a first period in which the first power is used, and switches the transmission power to the first power; and a communication unit that transmits a signal according to the first power.
