Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in the context of 5G, face challenges in efficiently managing transmission power to minimize interference and optimize power consumption, especially when handling diverse services with varying priority levels such as eMBB, Massive MTC, and URLLC.
Innovation Solution
A base station device is configured to determine whether to use a first method or a second method for calculating a single term in the equation for determining transmission power, and to notify the terminal device of this method. The first method uses a relative value based on previous values, while the second method uses an absolute value, allowing for adaptive adjustment of transmission power in response to changing communication environments and priority data transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If transmission power is adjusted using a fixed calculation method, then the system is simple to operate, but the wireless communication efficiency is low and interference cannot be minimized
Solution Approach 1:
The patent implements dynamic transmission power control by allowing the base station to switch between a first calculation method (using previous values) and a second calculation method (using absolute values) based on real-time communication conditions. This dynamic adjustment enables the system to adapt to changing network environments, minimize interference, and optimize power consumption while maintaining operational simplicity through automated method selection.
2Loss of time
If transmission power is rapidly adjusted to reduce latency, then the response time is improved, but the stability of transmission power control deteriorates
Solution Approach 1:
The patent changes the calculation parameters for transmission power by selecting between two different methods: the first method uses relative values based on previous transmission power levels, while the second method uses absolute values. This parameter change enables the system to achieve rapid response when needed while maintaining stability through appropriate method selection, thereby reducing latency without compromising power control stability.
3Adaptability or versatility
If a single calculation method is used for all data transmissions, then the system is easy to implement, but the adaptability to different service types and priority levels is insufficient
Solution Approach 1:
The base station dynamically selects between the first calculation method (based on previous values) and the second calculation method (based on absolute values) according to the service type and priority level of the data transmission. This dynamic method selection provides adaptability to different service requirements while keeping the implementation relatively simple through automated decision-making based on communication conditions.

AI summary
A base station device that communicates with a first terminal device that transmits first data includes: a controller configured to determine whether a calculation method for a single term among a plurality of terms included in an equation for determining a transmission power of the first terminal device is either a first method or a second method, the first method using a relative value based on a previous value of the single term, the second method using an absolute value that is irrelevant to the previous value of the single term; and a transmitter configured to transmit, to the first terminal device, notification information for notifying the calculation method determined by the controller.
