Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If network entities activate network energy saving modes to reduce power consumption, then energy efficiency is improved, but network operational capability deteriorates
Solution Approach 1:
The patent segments network energy saving modes into multiple distinct modes (first network energy saving mode, second network energy saving mode, etc.), each with different operational characteristics. This allows the network to select appropriate levels of power reduction based on traffic conditions, balancing energy savings with operational capability requirements.
Solution Approach 2:
The patent implements dynamic selection of network energy saving modes based on real-time traffic conditions. The network entity monitors traffic and dynamically transitions between different energy saving modes, adjusting operational capability according to current network demands rather than using a static fixed mode.
2Loss of energy
If network entities enter energy saving modes with reduced functionality, then power consumption decreases, but UE operational complexity increases
Solution Approach 1:
The network entity transmits advance information about the selected energy saving mode and associated UE operations to the UE before the mode is activated. This preliminary notification allows the UE to prepare for the changed operational state, reducing the complexity impact by providing advance warning and configuration details.
Solution Approach 2:
The patent establishes a feedback mechanism where the network entity monitors UE operations during energy saving modes and can adjust the mode selection or parameters based on UE performance and traffic conditions. This feedback loop optimizes the balance between power savings and UE operational simplicity.
3Loss of energy
If network entities transmit detailed operating state information to UEs, then energy saving effectiveness is improved, but signaling overhead increases
Solution Approach 1:
The patent applies different levels of detail in operating state information transmission based on local network conditions and UE requirements. The network entity can transmit comprehensive operating state details when needed for optimal energy savings, while using simplified signaling when network conditions allow for less detailed communication, thus balancing energy savings with signaling overhead.

AI summary
Methods, systems, and devices for wireless communications are described. A network entity may select a network energy saving mode from a set of network energy saving modes based on traffic conditions. The network entity may transmit a message indicating the network energy saving mode, a set of operating states corresponding to the network energy saving mode, and one or more time durations corresponding to the set of operating states, the set of operating states associated with one or more operating parameters corresponding to the one or more time durations. After transmitting the message, the network entity may activate the network energy saving mode for one or more components based on the one or more time durations. The UE may receive the message and perform one or more operations in accordance with the one or more operating parameters for the one or more time durations based on receiving the message.
