Network Entity Mode Management for Energy Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communications systems face challenges in balancing power consumption and network accessibility, as frequent broadcasts of signals like SIBs and SSBs enhance access but increase power usage, while infrequent broadcasts reduce access speed and efficiency.
Innovation Solution
A mode transitioning framework that allows network entities to switch between energy-saving modes by deactivating periodic signals like SSBs when no user equipment is actively using the network, while monitoring for uplink trigger messages to resume broadcasts, ensuring accessibility without excessive power use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network entity frequently broadcasts signals like SIBs and SSBs, then network accessibility is improved, but power consumption increases
Solution Approach 1:
The network entity transitions between active and energy-saving modes based on periodic monitoring of uplink trigger messages. During energy-saving mode, periodic signals are deactivated, and the entity periodically monitors for trigger messages at configured occasions. When triggered, it resumes active broadcasting, creating a periodic cycle between low-power and high-accessibility states that balances energy consumption with network accessibility requirements
Solution Approach 2:
The network entity dynamically adjusts its operational state between active mode (frequent broadcasting for high accessibility) and energy-saving mode (reduced broadcasting for low power consumption). This dynamic transition is controlled by the presence or absence of uplink trigger messages, allowing the system to adapt its power consumption and accessibility characteristics in real-time based on actual network needs
2Use of energy by moving object
If the network entity deactivates periodic signals to save power, then power consumption is reduced, but network accessibility deteriorates
Solution Approach 1:
The network entity implements a feedback mechanism where user equipment can send uplink trigger messages to indicate their need for network access. The network entity monitors these trigger messages during configured occasions and uses this feedback to determine whether to transition from energy-saving mode back to active mode, ensuring that accessibility is maintained when actually needed while allowing power savings when no devices require access
Solution Approach 2:
The system allows user equipment to self-initiate network access by transmitting uplink trigger messages when needed. This enables the network to remain in energy-saving mode without continuous broadcasting, while individual devices can independently request service when required, eliminating the need for constant proactive broadcasting by the network entity
3Speed
If the network entity monitors for uplink trigger messages continuously, then network responsiveness is improved, but power consumption increases
Solution Approach 1:
The network entity monitors for uplink trigger messages periodically at configured monitoring occasions rather than continuously. This periodic monitoring approach maintains network responsiveness to user equipment needs while significantly reducing power consumption compared to continuous monitoring, as the entity can enter low-power states between monitoring occasions

AI summary
Certain aspects of the present disclosure provide techniques for wireless communications in a network. A method includes receiving, from a first user equipment, a first uplink trigger message in a receive direction while in a first energy mode, wherein while in the first energy mode, the network entity is configured to: deactivate any synchronization signal blocks (SSBs) in the receive direction; monitor for uplink trigger messages during one or more configured uplink trigger occasions; and transitioning from the first energy mode to a second energy mode based at least in part on the first uplink trigger message, wherein while in the second energy mode, the network entity is configured to: activate one or more SSBs in the receive direction; and monitor for uplink trigger messages during the one or more configured uplink trigger occasions.
