Base Station Power Regulation via Dynamic Antenna Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high power consumption in telecommunication networks, particularly in LTE systems, due to the continuous transmission of downstream reference signals by base stations, leads to significant operational expenditures for carriers, even when no data is being sent.
Innovation Solution
A method and system where a base station dynamically adjusts the number of cell antennas or system bandwidth by sending an indication message to a terminal, using configuration parameters such as cell antenna information or system bandwidth information, to reduce power consumption while maintaining normal user communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station continuously transmits downstream reference signals to maintain user communication, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic transmission of downstream reference signals instead of continuous transmission. The base station transmits reference signals at predetermined intervals (e.g., every 10ms or 20ms) while remaining in a low-power state between transmissions. This periodic action maintains communication reliability by providing reference signals at sufficient intervals for channel estimation and signal tracking, while dramatically reducing power consumption by keeping the power amplifier in sleep mode during idle periods.
2Measurement precision
If the base station transmits downstream reference signals with high power spectrum density, then signal quality is improved, but power consumption increases
Solution Approach 1:
The patent dynamically adjusts the power spectrum density of downstream reference signals based on current communication conditions. The base station monitors channel quality indicators and user equipment feedback, then adapts the reference signal power accordingly. When channel conditions are good, the reference signal power is reduced; when conditions deteriorate, power is increased to maintain signal quality. This dynamic adjustment optimizes the trade-off between signal quality and power consumption.
3Use of energy by moving object
If the base station reduces the number of downstream reference signals to save power, then power consumption is reduced, but communication reliability may deteriorate
Solution Approach 1:
The patent changes multiple parameters of downstream reference signals simultaneously to maintain communication reliability while reducing power consumption. These parameters include: transmission timing (periodic intervals), power spectrum density (adaptive power levels), frequency resources (resource block allocation), and spatial parameters (beamforming weights). By coordinating changes across these parameters, the system achieves power reduction without compromising communication reliability.

AI summary
A method, device and system for regulating power consumption are provided in the embodiments of the present invention. A method for regulating power consumption includes: obtaining, by a base station, an application point and a configuration parameter; sending, by the base station, an indication message to a terminal according to the application point and configuration parameter; regulating, by the base station, the power consumption of the base station by using the configuration parameter at the application point; the configuration parameter comprises cell antenna information or system bandwidth information; the indication message instructs the terminal to use the configuration parameter at the application point. Under the condition that user's normal communication is remained, the number of cell antennas or the cell bandwidth is dynamically changed. This reduces the power consumption of the network device.
