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 harsh channel conditions and increased signal attenuation, leading to difficulties in managing radiation patterns effectively to minimize interference and optimize resource reuse.
Innovation Solution
A method for controlling a radiation boundary area by adjusting antenna system parameters based on received information, allowing communication devices to configure their radiation patterns to match the radiation boundary area, thereby optimizing energy density and reducing interference outside the designated area, while enabling network entities to adjust and improve radiation boundary areas dynamically.

Engineering Contradiction Analysis
1Object-generated harmful factors
If directive antennas are used instead of omnidirectional antennas to minimize undesired radiation and reduce interference, then interference towards other users is reduced and resource reuse rate increases, but the system requires increased knowledge and intelligent management by all nodes or base station
Solution Approach 1:
The patent introduces a base station as an intermediary that centrally manages and coordinates the radiation patterns of multiple directive antennas. Instead of requiring all nodes to have intelligent management capabilities, the base station acts as a mediator that allocates spatial resources and controls antenna beamforming, thereby reducing interference while maintaining manageable system complexity.
Solution Approach 2:
The system dynamically adjusts radiation patterns and beam directions based on real-time channel conditions and user positions. The base station continuously optimizes the spatial distribution of radiation energy, adapting the antenna system's behavior to changing environmental conditions, which enables efficient interference management without requiring static complex configurations at each node.
2Reliability
If radiation patterns are shifted from omnidirectional to beam-based to enhance Quality of Service, then the footprint of antenna system patterns becomes a valuable resource, but space allocation and determination of allocated space shape become important and complex
Solution Approach 1:
The patent extends resource allocation from traditional time and frequency dimensions to include the spatial dimension. By utilizing three-dimensional beamforming and spatial multiplexing, the system creates distinct spatial channels for different users, effectively adding a new dimension for resource differentiation. This allows multiple users to share the same time-frequency resources by transmitting in different spatial directions, thereby enhancing QoS while managing spatial allocation through established beamforming techniques.
3Adaptability or versatility
If higher frequency bands (mmWave) are used for V2X communications to leverage 5G capabilities, then spectrum availability and mobility support are improved, but channel-induced attenuation increases and satisfactory QoS becomes difficult to deliver
Solution Approach 1:
The patent combines multiple antenna elements into arrays and merges their radiation patterns through coherent beamforming to create focused, high-gain beams. By combining the signals from multiple antennas constructively in the desired direction, the system achieves sufficient signal strength and penetration through mmWave channels, thereby maintaining QoS reliability despite the inherent attenuation of higher frequency bands.
Solution Approach 2:
The system dynamically changes key radiation parameters including beam direction, beam width, and power distribution across antenna elements. By adapting these parameters in real-time based on channel conditions, the system optimizes signal propagation through the harsh mmWave environment, compensating for atmospheric effects and obstacles to maintain satisfactory QoS while utilizing the benefits of higher frequency bands.
