5G Network Entity Interference Control via Radiation Boundary Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, especially in V2X communications, higher frequency bands face challenges in maintaining satisfactory Quality of Service (QoS) due to increased signal power attenuation and interference from other devices, particularly in harsh propagation environments, which can lead to reduced Signal-to-Noise Ratio and interference issues.
Innovation Solution
A method for controlling communications between devices by utilizing a radiation boundary area, where a network entity receives a space allocation non-compliance message from a first communication device, determines interference with a second communication device, and transmits this information to the second device, allowing for adjustments to reduce or eliminate interference and improve communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If higher frequency bands are used in 5G wireless communication, then data transmission capacity and bandwidth are improved, but signal power attenuation and interference increase
Solution Approach 1:
The patent implements a feedback mechanism where communication devices report interference measurements to the network entity. The network entity receives interference indicators from devices and uses this feedback to determine and communicate interference information back to relevant devices, enabling dynamic adjustment of communication parameters to maintain signal quality despite using higher frequency bands
Solution Approach 2:
The network entity acts as an intermediary that collects interference information from communication devices, processes this information, and distributes relevant interference data to appropriate devices. This intermediary role enables coordinated interference management across the network, allowing devices to adjust their transmission parameters based on network-wide interference conditions rather than operating in isolation
2Adaptability or versatility
If radiation boundary areas are allocated to communication devices, then spatial resource utilization is improved, but interference from other devices using the same area increases
Solution Approach 1:
Devices monitor their radiation boundary areas for interference and provide feedback to the network entity. The network entity uses this feedback to identify interference sources and communicates this information back to affected devices, enabling them to adjust their spatial resource usage or transmission parameters to reduce interference while maintaining efficient spatial allocation
Solution Approach 2:
The patent enables dynamic adjustment of communication parameters such as beam direction, transmission power, and resource allocation based on detected interference conditions. When interference is detected in a radiation boundary area, devices can change their transmission parameters to avoid the interfering frequency-time-spatial resources, thereby maintaining spatial resource utilization while reducing interference impact

AI summary
A method for a network entity for controlling a communication between a first communication device and a second communication device. The method includes receiving from the first communication device a space allocation non-compliance (SANC) message having information about a usage of a radiation boundary area by the second communication device, the radiation boundary area being assigned for usage by the first communication device. The method also includes determining an interference between communication signals of the first and second communication devices in the radiation boundary area and transmitting information about the determined interference to the second communication device.
