Terminal Discontinuous Reception Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The method for saving power consumption in base stations has not been standardized in conventional technology, which is crucial for achieving carbon neutrality and Sustainable Development Goals (SDGs).
Innovation Solution
A terminal is provided with a transmission unit and a control unit that assumes the base station enables a discontinuous reception function, disabling the receiver unit when transmitting signals. This allows for the reduction of power consumption in base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station operates continuously to maintain communication readiness, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The base station implements discontinuous reception where the receiver unit operates periodically rather than continuously. The receiver is enabled during specific reception periods to receive uplink signals from terminals, and disabled during other periods to save power, while still maintaining communication reliability through scheduled operations
Solution Approach 2:
The receiver unit's operational state is dynamically adjusted based on communication needs. The base station controls the receiver unit to be in an enabled state during reception periods and a disabled state during non-reception periods, creating a dynamic power management system that adapts to traffic conditions
2Reliability
If the receiver unit is continuously enabled to receive signals, then signal reception reliability is improved, but power consumption increases
Solution Approach 1:
The receiver unit is enabled during specific reception periods and disabled during other periods. This periodic operation allows the base station to maintain signal reception capability when needed while significantly reducing power consumption during idle periods when no uplink signals are expected
Solution Approach 2:
The terminal is configured with knowledge of the base station's discontinuous reception pattern, allowing the terminal to self-adjust its transmission timing to coincide with the base station's reception periods, eliminating the need for continuous receiver operation

AI summary
A terminal includes: a transmission unit configured to transmit a signal to a base station; and a control unit configured to assume that the base station enables a discontinuous reception function for disabling a receiver unit when transmitting the signal.
