Terminal Control for Base Station Discontinuous Transmission Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies have not effectively standardized methods to reduce energy consumption in base stations, leading to potential channel or signal drops during inactive periods due to discontinuous transmission and reception by base stations.
Innovation Solution
A terminal is equipped with a control unit to manage the base station's discontinuous transmission and reception, including a communication unit for reception and a reception unit to handle control information, determining the activation or deactivation of physical downlink control channels during inactive periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the base station performs discontinuous transmission and reception to reduce energy consumption, then energy efficiency is improved, but channel or signal drops may occur during inactive periods
Solution Approach 1:
The base station implements discontinuous transmission and reception by periodically switching between active and inactive states. During inactive periods, the base station stops monitoring physical downlink control channels to save energy, while during active periods it恢复正常 monitoring and transmission operations
Solution Approach 2:
The system dynamically adjusts the base station's transmission and reception states based on traffic conditions and energy saving requirements. The base station can flexibly transition between continuous and discontinuous operation modes, optimizing the balance between energy consumption and signal reliability
2Loss of energy
If the base station dynamically activates or deactivates discontinuous transmission and reception, then energy saving is improved, but physical layer signaling may be dropped during inactive periods
Solution Approach 1:
The base station periodically activates and deactivates discontinuous transmission and reception based on predetermined cycles or triggering conditions. During deactivated periods, physical layer signaling is intentionally dropped to save energy, while during activated periods normal signaling is restored
Solution Approach 2:
The patent converts the potential harm of signal drops during inactive periods into a beneficial energy saving opportunity. By intentionally accepting signal drops during predetermined inactive periods, the system achieves significant energy reduction while maintaining acceptable communication performance during active periods

AI summary
A terminal includes: a control unit configured to expect that a base station performs a discontinuous transmission function for activating or deactivating a transmitter unit; a communication unit configured to perform reception from the base station, based on the expected discontinuous transmission function; and a reception unit configured to receive control information related to the discontinuous transmission function from the base station. The control unit determines whether or not to expect to receive, from the base station, a physical downlink control channel for an indication of dynamically activating or deactivating at least one of a cell discontinuous transmission or a cell discontinuous reception during an inactive period in the discontinuous transmission function.
