Solution Overview
Problem
Current telecommunication systems, particularly base stations, face significant energy consumption due to high data throughput requirements, leading to increased operational costs and environmental impact, despite efforts to optimize energy efficiency at the component level.
Innovation Solution
Implementing a power saving mode in base stations that increases the interval between frame structured signals, allowing for reduced energy usage by interrupting unnecessary frame transmissions during low load scenarios and transmitting only essential data regions, while maintaining system synchronization and information availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations transmit frame structured signals periodically with normal interval to maintain high data throughput and system synchronization, then service quality and coverage are ensured, but energy consumption increases significantly
Solution Approach 1:
The patent applies periodic action by transitioning from continuous periodic frame transmissions at normal intervals to extended periodic transmissions during power saving mode. The base station increases the interval between frame structured signals, transmitting frames only at extended intervals rather than continuously, thereby reducing energy consumption while maintaining essential service functionality through periodic updates of system information and synchronization signals.
2Use of energy by moving object
If base stations increase transmission interval to power saving interval to reduce energy consumption, then energy efficiency improves, but system synchronization and information availability may be compromised
Solution Approach 1:
The patent maintains continuity of useful action by ensuring that essential system information, synchronization signals, and broadcast channels continue to be transmitted periodically even during power saving mode. While the overall frame transmission interval is extended, critical information required for system synchronization and basic service functionality is maintained with appropriate periodicity, ensuring continuous availability of essential services.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the transmission interval parameter based on traffic conditions. During power saving mode, the interval between frame structured signals is increased from normal interval to power saving interval. The system can switch between different transmission interval parameters depending on whether normal service mode or power saving mode is active, optimizing the balance between energy consumption and information availability.
3Reliability
If base stations transmit all data regions in every frame to ensure complete service coverage, then service quality is maintained, but unnecessary energy is consumed during low load scenarios
Solution Approach 1:
The patent applies the extraction principle by selectively transmitting only essential data regions and system information during power saving mode, rather than transmitting all data regions in every frame. Non-critical data transmissions are omitted or consolidated, extracting and transmitting only the essential components required for maintaining basic service coverage and system functionality, thereby eliminating unnecessary energy consumption.

AI summary
The present invention relates to a method for energy saving in a telecommunication system with at least one first base station for enabling communication within a cell. A signal 23 having a frame structure is transmitted and received in the cell by the first base station, the structure of the frame comprises a downlink frame part 15 and an uplink frame part 16. Each frame part 15,16 has the ability of carrying at least one data region 19,21 allocated to at least one user or broadcasted for the traffic flow between the telecommunication network and the user terminal via the first base station. The downlink frame part 15 comprises an overhead part with at least synchronization 17 or system 18 information. The frame structured signal 23 is transmitted periodically Frame N, Frame N+1, Frame N+2, Frame N+3 with a normal interval defined by the system. The method is particularly characterized in that the system during a power saving mode increases the interval between at least a first 23 and the next following second frame structured signal 23 to a power saving interval.
