Prioritizing Wireless Resource Reception to Avoid Beam Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G new radio (NR) technology, user equipment (UE) supporting multiple panels faces challenges in receiving multiple downlink channels or reference signals using different beams, as the UE's behavior is unknown when different beams are associated with the same panel, leading to potential collisions and degraded performance.
Innovation Solution
The proposed solution involves prioritizing the reception of a first resource over a second resource when certain conditions are met, such as overlapping resources, lack of TCI state configuration for the second resource, or specific information associations between the resources. This prioritization allows the UE to manage beam associations effectively and avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple downlink channels or reference signals are received using different beams simultaneously, then the UE can receive more channels/signals, but beam collisions occur when different beams are associated with the same panel
Solution Approach 1:
The patent introduces a prioritization mechanism that changes the parameter of beam association by establishing a hierarchy between multiple beams. When multiple beams are associated with the same panel, the system determines a prioritization order and applies different association rules based on this order, allowing the UE to selectively associate beams with panels to avoid collisions while maximizing channel reception capability.
2Reliability
If the UE prioritizes reception of a first resource over a second resource, then reception reliability is improved, but resource utilization efficiency decreases
Solution Approach 1:
The patent applies local quality by differentiating the handling of different resources based on their specific characteristics and association relationships. Instead of uniform treatment, the system evaluates each resource's TCI state, panel association, and prioritization status to apply appropriate reception rules locally, ensuring reliable reception of critical resources while maintaining efficient utilization of less critical ones.
