Solution Overview
Problem
Existing wireless communication networks face challenges in dynamically managing beamformed communication links due to static compatibility determinations based on limited factors, which do not account for varying propagation conditions and device capabilities, leading to inefficiencies in link activation and deactivation.
Innovation Solution
The wireless device and network node implement mechanisms to determine compatibility states of beamformed communication links based on current radio signal characteristics, allowing for dynamic de-activation and re-activation of links in response to changing propagation conditions and device capabilities, enabling adaptive management of beam-pair links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If beamformed communication links are managed with static compatibility determinations based on limited factors, then device complexity is reduced and ease of operation is improved, but adaptability to varying propagation conditions and device capabilities deteriorates
Solution Approach 1:
The patent implements dynamic compatibility determination for beamformed communication links by continuously monitoring radio signal characteristics (RSRP, RSRQ, SINR) and device capability states. The compatibility state is not fixed but dynamically updated based on current propagation conditions and device capabilities, allowing the system to adapt to changing environments while maintaining manageable complexity through automated monitoring and evaluation procedures.
2Productivity
If beamformed communication links are managed with static compatibility determinations, then ease of operation is improved, but network performance deteriorates due to inefficiencies in link activation and deactivation
Solution Approach 1:
The patent employs feedback mechanisms where the wireless device continuously monitors radio signal characteristics and device capability states for each beamformed communication link. This feedback information is used to dynamically evaluate compatibility states and trigger appropriate actions (activation, deactivation, or maintenance of links). The feedback loop ensures efficient link management by automatically responding to changing conditions without requiring manual intervention, thus improving productivity while maintaining ease of operation.
3Adaptability or versatility
If dynamic compatibility determination based on current radio signal characteristics is implemented, then adaptability to propagation conditions is improved, but use of energy increases due to continuous monitoring and evaluation
Solution Approach 1:
The patent implements periodic monitoring and evaluation of radio signal characteristics and device capability states for beamformed communication links. Instead of continuous real-time monitoring, the system performs compatibility determinations at periodic intervals or triggered by specific events (such as changes in propagation conditions or device state). This periodic approach maintains real-time adaptability while significantly reducing energy consumption compared to continuous monitoring, as the wireless device can enter low-power states between evaluation periods.
