Solution Overview

Problem

Current 3GPP NR protocol-based beam management procedures are controlled by the network side, which cannot anticipate issues such as beam inapplicability due to user equipment (UE) movement or excessive emission by certain antenna panels.

Innovation Solution

An electronic apparatus and method for wireless communications where the user equipment (UE) determines physical layer beam management events and initiates beam management procedures, including beam sweeping, reporting, activation, and selection, to address spatial beam issues dynamically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If beam management is controlled by the network side, then the network side can take control of wireless resources from an overall perspective, but the network side cannot know in advance about spatial beam problems such as beam inapplicability due to UE movement or excessive emission by certain antenna panels

Engineering Contradiction:

Improvebeam management adaptabilityVSAvoidbeam management latency

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The UE autonomously detects physical layer beam management events (such as beam failure, beam blockage, or antenna panel issues) and independently initiates beam management procedures without waiting for network side detection or instruction. This self-service mechanism enables the UE to respond immediately to spatial beam problems, reducing latency while allowing the network side to maintain overall resource control through configuration and coordination.

Inventive Principle:

Principle #25Self-service

2Reliability

If the network side controls beam management procedures, then resource control is centralized, but the response to physical layer beam events is delayed

Engineering Contradiction:

Improvebeam management controlVSAvoidbeam management response speed

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The beam management functionality is segmented into two parts: (1) Network side performs high-level resource control, configuration, and coordination; (2) UE performs low-level physical layer beam event detection and immediate response. This segmentation allows both centralized control reliability and fast local response speed to be achieved simultaneously.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The network side pre-configures the UE with beam management parameters, event detection thresholds, and procedure configurations before the UE encounters physical layer beam issues. This preliminary action enables the UE to immediately execute appropriate beam management procedures upon detecting events, reducing response latency while maintaining network control.

Inventive Principle:

Principle #10Preliminary action
