Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies due to changes in beam quality caused by user equipment (UE) mobility, leading to reduced network performance, increased retransmissions, and latency.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single beam is used for common channel communication, then device complexity is reduced, but network performance deteriorates due to UE mobility causing beam quality changes
Solution Approach 1:
The patent segments the beam configuration into multiple beams (first set of beams and second set of beams) that can be independently selected and switched based on communication conditions. This allows the system to maintain communication reliability by switching between beam segments when mobility causes quality degradation, while keeping the overall configuration manageable through structured organization.
Solution Approach 2:
The patent implements dynamic beam selection where the network node can switch between different beam sets based on real-time communication threshold assessments. The system dynamically adapts the active beam configuration in response to changing UE mobility conditions, maintaining optimal communication performance without requiring complex static configurations.
2Reliability
If beam sweeping is implemented to adapt to UE mobility, then communication reliability improves, but latency increases due to beam switching overhead
Solution Approach 1:
The patent configures multiple beams in advance (first set of beams and second set of beams) before actual communication occurs. This preliminary beam preparation allows the system to quickly switch between pre-configured beams when mobility changes are detected, reducing the latency that would otherwise be incurred during beam acquisition and alignment.
Solution Approach 2:
The patent employs communication threshold feedback mechanisms where the network node continuously monitors beam quality and compares it against predefined thresholds. When degradation is detected, the system uses this feedback to trigger appropriate beam switching, ensuring that latency is minimized by acting on real-time conditions rather than relying on delayed or predictive adjustments.
3Productivity
If multiple beams are used for common channel communication, then network performance improves, but device complexity increases
Solution Approach 1:
The patent organizes multiple beams into structured segments (first set of beams and second set of beams) with distinct roles and selection criteria. This segmentation allows the system to manage beam complexity through hierarchical organization, where each segment can be independently controlled and switched based on communication needs, making the overall multi-beam system more manageable.
Solution Approach 2:
The patent uses communication threshold parameters to dynamically control beam selection. By changing the active beam configuration based on measurable parameters (signal quality, mobility conditions), the system automates beam management decisions, reducing the operational complexity of managing multiple beams while maintaining optimal network performance.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a request for a first common channel communication. The UE may receive, over at least one beam of a first set of beams, the first common channel communication. The UE may receive, over at least one beam of a second set of beams and based, at least in part, on a communication threshold, a second common channel communication.Numerous other aspects are described.
