Wireless Signal Sending for Energy-Saving Node Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high energy consumption of wireless networks, particularly in 5G networks, is a significant operational expense for mobile network operators, with a substantial portion attributed to active antenna units, necessitating energy-saving technologies.
Innovation Solution
A method involving a first wireless communication node sending indication information to a second node in a deactivated, closed, or incommunicable state to control signal transmission, reducing energy consumption by managing signal sending based on terminal device measurements, location, and switching probabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication nodes continuously transmit signals to maintain network coverage and responsiveness, then network reliability and responsiveness are improved, but energy consumption increases significantly
Solution Approach 1:
The patent implements dynamic state transitions for wireless communication nodes between active, inactive, and closed states. Nodes can be deactivated or closed when not needed, and reactivated upon receiving indication information from neighboring nodes, allowing the network to adapt its energy consumption patterns to actual traffic conditions while maintaining responsiveness.
Solution Approach 2:
The patent uses indication information transmitted by active nodes to pre-activate or prepare neighboring nodes before they are actually needed for communication. This allows nodes to be in a ready state rather than completely dormant, reducing activation delay while still avoiding continuous full-power operation.
2Use of energy by moving object
If wireless communication nodes are deactivated or closed to save energy, then energy consumption is reduced, but network coverage and signal availability decrease
Solution Approach 1:
The patent merges the coverage areas of multiple wireless communication nodes by coordinating their activation states. When one node is deactivated, neighboring nodes remain active or are quickly reactivated to cover the same geographic area, ensuring continuous network coverage through combined node operations.
Solution Approach 2:
The patent introduces indication information as an intermediary mechanism that coordinates between active and deactivated nodes. This information carrier enables deactivated nodes to be selectively reactivated based on network conditions, allowing coverage to be dynamically adjusted without permanent loss of service area.
3Use of energy by moving object
If wireless communication nodes operate in inactive or closed states, then energy consumption is minimized, but communication capability and service availability are reduced
Solution Approach 1:
The patent creates a dynamic communication system where nodes can transition between full operation, partial operation, and dormant states based on actual communication needs. This allows the network to adapt its communication capability to match traffic patterns, maintaining full capability when needed and reducing it when not needed to save energy.
Solution Approach 2:
The patent changes the operational parameters of wireless communication nodes, specifically their transmission power and state (active/inactive/closed), based on indication information from the network. This allows flexible adjustment of communication capability to balance energy consumption and service availability.
