Base Station DRX Configuration for Terminal Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of terminal devices managed by a base station device leads to an increased load, and existing discontinuous reception (DRX) settings lack flexibility, making it challenging to optimize power consumption effectively in wireless communication systems.
Innovation Solution
A base station device that refers to stored discontinuous reception information to selectively transmit data during specific reception periods, adjusting transmission times based on response information received from terminal devices, allowing for flexible DRX settings and reduced load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base station device determines and manages DRX settings for each terminal device, then the terminal device can achieve flexible discontinuous reception and reduced power consumption, but the base station device experiences increased processing load
Solution Approach 1:
The terminal device autonomously selects an appropriate DRX setting from multiple candidates provided by the base station, based on its own operation status and requirements. This self-selection mechanism eliminates the need for the base station to determine and manage DRX settings for each terminal, thereby reducing base station processing load while maintaining flexible and adaptive DRX configurations tailored to each terminal's needs
2Use of energy by moving object
If the base station device manages multiple terminal devices with individual DRX settings, then each terminal can optimize power consumption, but the overall system complexity and processing requirements increase
Solution Approach 1:
The base station device pre-provides multiple candidate DRX settings to the terminal device before the terminal needs to make a selection. The terminal then autonomously selects the most appropriate setting based on its current operation status. This preliminary provision of multiple options enables optimized power consumption without requiring continuous base station intervention, thereby reducing ongoing system processing load
Solution Approach 2:
The terminal device independently determines the optimal DRX setting from the provided candidates based on its own operation status, eliminating the need for the base station to continuously manage and adjust DRX settings for each terminal. This self-service approach allows each terminal to optimize its power consumption while the base station maintains a simplified role

AI summary
A base station device includes: a communication unit configured to wirelessly communicate with a terminal device; a storage unit; and a control unit. The control unit is configured to refer to discontinuous reception information, stored in the storage unit, which indicates a plurality of discontinuous reception settings, transmit transmission data to the terminal device in at least a portion of a first reception period of time corresponding to at least one of the discontinuous reception settings, and transmit the transmission data to the terminal device in at least a portion of a second reception period of time corresponding to at least another one of the discontinuous reception settings in a case that it is determined that response information with respect to the transmitted transmission data is not received.
