5G Base Station Sleep Mode Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in reducing power consumption and operational costs, especially with the increased demand for higher data rates and connectivity, as they often require continuous operation of base station components, leading to inefficiencies and increased energy usage.
Innovation Solution
Implementing a mechanism for base stations to enter a sleep mode based on uplink and downlink traffic needs, allowing components to power down during low-activity periods without disconnecting connected user equipment, and synchronizing with user equipment to refrain from transmitting during these periods, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base station components operate continuously to meet growing data rate and connectivity demands, then network reliability and service quality are improved, but power consumption and operational costs increase
Solution Approach 1:
The base station dynamically transitions between active and sleep modes based on real-time traffic conditions. During low-activity periods, the base station enters sleep mode to reduce power consumption, while during high-activity periods, it transitions to active mode to maintain service quality, thus resolving the contradiction between continuous operation and energy efficiency
Solution Approach 2:
The base station implements periodic sleep cycles with defined active and sleep periods. This periodic operation allows the base station to conserve energy during low-traffic intervals while ensuring availability during high-traffic intervals, balancing reliability requirements with power consumption reduction
2Use of energy by moving object
If base station enters sleep mode to reduce power consumption, then energy efficiency is improved, but connection stability and user equipment connectivity may be affected
Solution Approach 1:
Before the base station enters sleep mode, it performs preliminary actions including notifying user equipment of upcoming sleep periods and completing any pending data transmissions. This ensures that user equipment can adjust its transmission schedule and avoids disruption during the sleep mode transition, maintaining connection stability
Solution Approach 2:
The system implements feedback mechanisms where user equipment reports traffic needs and connectivity requirements to the base station. The base station uses this feedback to determine optimal sleep mode entry timing and duration, ensuring that sleep mode transitions do not adversely affect connection stability for active users

AI summary
Wireless communications systems and methods related to network power saving are provided. In one embodiment, a base station (BS) of a wireless communication network determines to enter a sleep mode. The BS transmits, to one or more user equipment (UEs) of the wireless communication network, a communication signal indicating that the BS will enter the sleep mode. The BS operates in the sleep mode for a sleep mode period. In one embodiment, a UE receives, from a BS, a communication signal indicating that the BS will enter a sleep mode for a sleep mode period. The UE refrains, during one or more sleep windows of the sleep mode period, from performing uplink communications.
