Smart Repeater Power Saving via Triggering Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless repeaters in communication systems face high power consumption due to constant monitoring of control channels, especially when not attached to a UE or when the UE is powered off, leading to inefficient relay operations.
Innovation Solution
Implementing a control interface triggering configuration that includes power threshold information, allowing repeaters to operate in a low power state and transition to active monitoring only upon detection of specific energy levels or power profiles in periodic signals, such as synchronization signal blocks, to reduce unnecessary power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeaters constantly monitor control channels to ensure reliable communication, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The repeater transitions from continuous monitoring to periodic monitoring of control channels. It wakes up at predetermined intervals to check for control information and returns to sleep mode, thereby reducing power consumption while maintaining the ability to receive important control signals when needed.
Solution Approach 2:
The repeater autonomously manages its own power state by monitoring energy levels of periodic signals and independently transitioning between active and sleep modes based on detected conditions, without requiring constant external control commands.
2Speed
If repeaters operate in active state to maintain ready communication, then response speed is improved, but power consumption increases
Solution Approach 1:
The repeater dynamically adjusts its operational state based on detected signal conditions. When energy levels of periodic signals indicate active communication needs, the repeater transitions to active state for fast response. When no significant signals are detected, it enters sleep mode to conserve power, creating a dynamic adaptation between speed and energy consumption.
Solution Approach 2:
The repeater performs preliminary detection of periodic signal energy levels during sleep mode before transitioning to active state. This allows it to prepare for potential communication needs without maintaining full active state continuously, optimizing the balance between response readiness and power consumption.
3Productivity
If repeaters monitor control channels frequently to detect communication needs, then communication responsiveness is improved, but energy waste increases
Solution Approach 1:
The repeater implements periodic monitoring at predetermined intervals instead of continuous monitoring. This reduces the frequency of control channel checks to only when necessary, minimizing energy waste from unnecessary monitoring while still maintaining adequate communication responsiveness through strategic wake-up cycles.

AI summary
Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for wireless device (e.g., wireless repeater, wireless relay device, smart repeater, etc.) operation in a low power state, and base station signaling for triggering of wireless repeater control interface configuration. For example, a wireless repeater may operate in a power saving mode and monitor for control information from a base station according to a low power state or a slow state (e.g., according to a long monitoring periodicity relative to a monitoring periodicity associated with a full power state or fast state). Upon detection of triggering signal from a base station, the wireless repeater may transition to monitoring for control information from the base station according to a fast state (e.g., according to a short, or more frequent, monitoring periodicity relative to a monitoring periodicity associated with a low power state).
