Base Station DTX DRX Configuration for Network Energy Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid increase in energy consumption in mobile communication networks, particularly in millimeter wave bands, due to the deployment of various types of base stations and radio access points, leads to performance degradation and inefficiencies in signal transmission, necessitating a method to optimize energy usage without compromising service quality.
Innovation Solution
Implementing a network energy saving technique that involves configuring discontinuous transmission (DTX) and discontinuous reception (DRX) operations based on the state of terminals within service coverage and service quality, using DTX configuration information and DRX configuration information transmitted in RRC messages, and activating/deactivating these operations through MAC control elements or DCI, allowing for energy-saving transmission-off operations.

Engineering Contradiction Analysis
1Productivity
If base stations and radio access points are widely deployed to support wide system bandwidth and high-frequency transmission, then service coverage and data capacity are improved, but energy consumption increases rapidly
Solution Approach 1:
The patent implements discontinuous transmission (DTX) and discontinuous reception (DRX) operations that periodically activate and deactivate transmission/reception functions based on traffic conditions. The base station configures DTX/DRX parameters including cycle lengths, on-duration timers, and offset values to create periodic operational patterns that reduce energy consumption during low-traffic periods while maintaining service availability
Solution Approach 2:
The patent dynamically adjusts transmission and reception operations based on real-time traffic conditions and terminal states. The base station monitors traffic load, terminal activity, and service quality requirements to dynamically switch between active and dormant states, configuring DTX/DRX parameters adaptively to balance energy savings with service quality maintenance
2Use of energy by moving object
If discontinuous transmission and discontinuous reception operations are activated to save energy, then energy consumption is reduced, but service quality may deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where terminals report their states, traffic conditions, and service quality metrics to the base station. The base station uses this feedback to adjust DTX/DRX configuration parameters, ensuring that energy-saving operations do not compromise service quality. The feedback loop enables continuous optimization of the balance between energy consumption and service quality
Solution Approach 2:
The patent applies different DTX/DRX configuration parameters to different terminals or terminal groups based on their specific service quality requirements, traffic patterns, and channel conditions. High-priority terminals or those with stringent service quality requirements receive configurations that maintain higher service levels, while other terminals receive more aggressive energy-saving parameters
3Adaptability or versatility
If DTX and DRX operations are configured separately with independent parameters, then energy saving flexibility is improved, but device complexity increases
Solution Approach 1:
The patent combines DTX and DRX configuration into a unified framework where the base station manages both operations through integrated parameter sets. By merging the configuration process and using coordinated parameter adjustments, the patent reduces the operational complexity for both the base station and terminals while maintaining the flexibility benefits of separate DTX and DRX operations

AI summary
A method of a base station may comprise: transmitting discontinuous transmission (DTX) configuration information for a DTX operation to a terminal; transmitting discontinuous reception (DRX) configuration information for a DRX operation to the terminal; and transmitting information indicating activation of at least one of the DTX operation and the DRX operation to the terminal, wherein the DTX operation and the DRX operation are configured separately.
