Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LTE communication system cannot support millimeter wave communications due to signal attenuation by oxygen, water vapor, and rain, leading to a reduced coverage range and inefficiency in relay nodes, especially in applications requiring multiple connections like machine-type communications or Internet-of-Things, where conventional one-to-one relay is insufficient.
Innovation Solution
An electronic device for a network control terminal and network node that determines and configures beam-forming capability to select relay nodes, enabling one-to-many relay and improving spectrum resource utilization through spatial multiplexing, by setting conditions for beam-forming and link quality, and generating control signaling to instruct network nodes on their operation as relay nodes.

Engineering Contradiction Analysis
1Productivity
If conventional one-to-one relay is used in LTE system, then relay node can provide basic coverage extension, but operation efficiency is low when multiple connections are required
Solution Approach 1:
The relay node is configured to support multiple UE connections simultaneously through multi-connectivity, allowing a single relay node to serve multiple functions and multiple users, thereby improving operation efficiency and reducing the need for multiple dedicated relay nodes
Solution Approach 2:
Multiple UE connections are merged through a single relay node using multi-connectivity architecture, combining multiple communication paths and resources at the relay node to handle multiple connections efficiently
2Quantity of substance
If millimeter wave communications are used, then spectrum resources are abundant and capacity requirements are met, but signal attenuation by oxygen, water vapor and rain greatly reduces effective communication distance
Solution Approach 1:
A relay node is introduced as an intermediary between the base station and remote UE, receiving signals from the base station and forwarding them to the UE, thereby overcoming the limited direct communication distance of millimeter wave signals while utilizing abundant spectrum resources
Solution Approach 2:
The system uses beamforming technology to concentrate signal energy in specific directions, improving signal quality and effective communication distance in local areas where relay nodes are deployed, while maintaining millimeter wave spectrum utilization
3Area of stationary object
If relay node is deployed to extend coverage in millimeter wave band, then communication range is extended, but spectrum resource utilization efficiency decreases with conventional one-to-one relay
Solution Approach 1:
The relay node is designed to handle multiple UE connections simultaneously through multi-connectivity, making the relay node universally applicable to multiple users and communication paths, thereby improving spectrum resource utilization efficiency while maintaining extended coverage
Solution Approach 2:
The system transitions from one-to-one relay to one-to-many relay by adding the dimension of multiple concurrent connections at the relay node, utilizing multi-connectivity to establish multiple communication dimensions simultaneously, thereby improving resource utilization without sacrificing coverage extension
