Terminal Discontinuous Reception Control for Base Station Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The method for saving power consumption of 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 reception unit to receive control information from a base station indicating the status of a discontinuous reception function, and a control unit to determine whether the base station has enabled this function based on the control information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station continuously operates the receiver unit to maintain communication readiness, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The base station implements discontinuous reception by periodically activating and deactivating the receiver unit according to a predetermined cycle. The terminal receives control information indicating the activation status and transmits uplink signals only during active periods, achieving periodic communication that reduces power consumption while maintaining necessary communication reliability.
2Use of energy by moving object
If the base station disables the receiver unit to save power, then power consumption is reduced, but communication responsiveness deteriorates
Solution Approach 1:
The base station transmits control information to the terminal in advance indicating whether the receiver unit is activated. This preliminary notification allows the terminal to prepare uplink transmissions appropriately, ensuring that communication can resume quickly when the receiver is activated without significant delay, thus maintaining responsiveness while enabling power savings during inactive periods.
3Use of energy by moving object
If the base station implements discontinuous reception function, then power consumption is saved, but system complexity increases
Solution Approach 1:
A control information mechanism serves as an intermediary between the base station's receiver activation status and the terminal's transmission behavior. The control information carries activation status indicators that coordinate the terminal's uplink transmissions with the base station's receiver state, managing the discontinuous reception system with minimal complexity through standardized signaling.

AI summary
A terminal includes: a reception unit configured to receive control information from a base station indicating an indication related to a discontinuous reception function for the base station to disable a receiver unit; and a control unit configured to determine whether or not the base station has enabled the discontinuous reception function, based on the control information.
