Base Station Control Signal Transmission Interval Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in reducing power consumption, particularly in base stations (BS), which contribute significantly to energy consumption and have not been adequately addressed by existing technologies.
Innovation Solution
The method involves adjusting the transmission interval of control signals in base stations to reduce power consumption by switching between shorter and longer intervals based on the presence of user equipment (UE) and network conditions, allowing for the implementation of sleep modes and resource allocation optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station transmits control signals at short intervals to maintain communication quality, then the reliability of communication is improved, but the power consumption of the base station increases
Solution Approach 1:
The base station dynamically adjusts the transmission interval of control signals based on the presence and state of user equipment. When no UE is present or in low-activity states, the transmission interval is extended to reduce power consumption. When UE is active, the interval is shortened to maintain communication reliability. This dynamic adjustment resolves the contradiction between maintaining reliable communication and reducing power consumption.
Solution Approach 2:
The patent changes the transmission parameter (time interval) of control signals based on system state. By adjusting the transmission interval from short to long periods depending on UE presence and activity, the system optimizes the balance between communication reliability and power consumption without compromising essential communication functions.
2Speed
If the base station transmits control signals frequently to ensure timely communication, then the speed of communication response is improved, but the power consumption increases
Solution Approach 1:
The base station implements periodic transmission of control signals with variable periods. Instead of continuous or fixed-interval transmission, the system uses adaptive periodic transmission where the period length adjusts based on UE activity. This reduces power consumption during idle periods while maintaining adequate response speed when needed.
Solution Approach 2:
The transmission interval is made dynamic rather than static, allowing the base station to respond to changing communication needs. When UE is active, shorter intervals provide faster response; when inactive, longer intervals conserve energy. This dynamic approach resolves the contradiction between response speed and power consumption.
3Adaptability or versatility
If the base station maintains continuous transmission intervals to ensure communication availability, then the adaptability to communication demands is improved, but the power consumption increases
Solution Approach 1:
The base station monitors its own transmission needs and automatically adjusts transmission intervals based on detected UE presence and activity states. This self-service mechanism allows the system to maintain communication availability when needed while reducing power consumption during idle periods, without requiring constant external control or intervention.

AI summary
A method for reducing the consumption of the transmission power in the base station by adjusting the transmission interval between the control signals comprises the steps of: changing the interval between the control signals transmitted from the base station from a first interval to a second interval and transmitting the control signal; receiving a first message including transmission interval adjustment request information of the control signal; and changing the interval between the control signals to the first interval and transmitting the control signal.
