Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional base station transceivers, particularly small cells, lack dynamic control over common channel transmission power, leading to inefficient handover and cell reselection behaviors in mobile communication systems, especially in vehicular environments where power adaptations are needed quickly to maintain service quality.
Innovation Solution
An apparatus and method for dynamically controlling the output power of a base station transceiver, using a coupling module to adjust radio signal transmission power based on information such as vehicle movement and neighboring cell signal quality, allowing for real-time adaptation of transmission power without deactivating service provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the transmission power of common channel is kept constant, then the coverage area remains stable, but handover behavior cannot be dynamically influenced and system performance deteriorates in mobile scenarios
Solution Approach 1:
The patent implements dynamic transmission power control for the common channel by adjusting power levels based on detected mobile transceiver behaviors. The base station continuously monitors handover patterns and adapts the common channel power accordingly, transforming a static system into a dynamic one that responds to real-time conditions.
Solution Approach 2:
The system employs feedback mechanisms where the base station observes handover behavior of mobile transceivers and uses this information to adjust common channel transmission power. This closed-loop control enables the system to learn from past behaviors and optimize power allocation dynamically.
2Productivity
If additional cells are deployed to increase capacity, then system capacity improves, but interference increases and power management complexity grows
Solution Approach 1:
The patent applies different transmission power levels to different channels (common channel versus dedicated channels) and different cells based on local conditions. By optimizing common channel power specifically, the system achieves better overall capacity management while controlling interference through localized power adjustments rather than blanket power changes.

AI summary
Embodiments provide apparatuses, methods and computer programs for controlling an output power of a base station transceiver and for a base station transceiver. A base station transceiver (100; 100a; 100b; 100c) is configured to provide wireless services to one or more mobile transceivers (200) of a communication system (300). An apparatus (10) for controlling an output power during service provision of a base station transceiver (100; 100a; 100b; 100c) of the mobile communication system (300) comprises a coupling module (12) to affect a radio signal transmission power of the base station transceiver (100; 100a; 100b; 100c), and a control module (14) to obtain information related to an output power adaption for the base station transceiver (100; 100a; 100b; 100c) and to control the output power of the base station transceiver (100) using the coupling module (12) based on the information related to the output power adaption. An apparatus (20) for a base station transceiver (100; 100a; 100b; 100c) of a mobile communication system (300) comprises a transmission module (22) to transmit a common signal. A transmission power of the common signal influences a service coverage area of the base station transceiver (100; 100a; 100b; 100c). The apparatus (20) further comprises a control module (24) to control the transmission module (22), and to adjust the transmission power for the common signal dynamically during service provision of the base station transceiver (100; 100a; 100b; 100c).
