Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication systems face challenges in coordinating periodic discontinuous transmission (DTX) mode on the cell side with periodic discontinuous reception (DRX) mode on the user equipment side, leading to inefficiencies in power consumption and service quality, particularly in dense deployment regions with varying data traffic and inter-cell interference.
Innovation Solution
The system configures a device with a cell configuring unit that controls the periodic DTX mode based on load and inter-cell interference conditions, aligning the DTX mode with the DRX mode on the user equipment side, allowing for staggered activation times and extended activation durations to reduce power consumption and inter-cell interference, while ensuring service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If the cell enters sleeping state to save power, then power consumption is reduced, but communication service may be lost when terminal needs data transmission
Solution Approach 1:
The cell operates in periodic DTX mode with alternating activation and sleeping time durations, allowing it to enter low-power states while maintaining scheduled communication windows that align with terminal DRX cycles, thus balancing power savings with service availability
Solution Approach 2:
The network pre-configures DTX parameters including activation time duration and sleeping time duration before terminal connection, and terminals pre-configure corresponding DRX parameters to ensure synchronized wake-up times and avoid communication failures
2Use of energy by stationary object
If small cell on/off is implemented based on random data packet arrival, then power consumption is reduced, but performance loss occurs for traditional users
Solution Approach 1:
Instead of random on/off switching based on packet arrival, the cell adopts periodic DTX with fixed activation and sleeping durations, providing predictable service windows for terminals while maintaining power savings through regular low-power cycles
Solution Approach 2:
The DTX parameters including activation time duration and sleeping time duration are dynamically configurable based on traffic conditions, allowing the system to adapt between more aggressive power saving modes and more service-oriented modes as needed
3Reliability
If the cell extends activation time duration to improve service, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The cell uses periodic DTX operation with configurable activation and sleeping durations, allowing flexible adjustment of the ratio between active service time and power-saving time to balance reliability requirements against power consumption targets
