Solution Overview

Problem

In wireless communication systems, existing methods for transmitting beam information between terminals and base stations are inefficient, leading to unnecessary resource allocation and increased signaling overhead, particularly in scenarios requiring beam recovery procedures.

Innovation Solution

A method where a terminal transmits beam information specifically for cells requiring recovery, allowing the base station to determine whether to perform beam recovery or deactivation, thereby minimizing resource allocation and reducing signaling overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If beam information is transmitted for all cells, then the base station has complete information for beam management, but signaling overhead and unnecessary resource allocation increase

Engineering Contradiction:
Improvebeam management reliabilityVSAvoidsignaling overhead
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential beam information for cells requiring recovery procedures, excluding unnecessary information from cells that do not require recovery. This selective extraction reduces signaling overhead while maintaining the reliability needed for beam management in critical cells.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different beam information transmission strategies to different cells based on their specific requirements. Cells requiring recovery receive detailed beam information, while cells without recovery needs receive minimal or no information, optimizing the balance between reliability and signaling overhead for each cell's specific needs.

Inventive Principle:
Principle #3Local quality

2Reliability

If beam recovery procedure is performed for all cells, then comprehensive beam management is achieved, but resource allocation efficiency decreases

Engineering Contradiction:
Improvebeam recovery reliabilityVSAvoidresource allocation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies partial beam recovery procedures only to cells that actually require recovery, rather than uniformly applying recovery procedures to all cells. This partial action approach maintains reliability for affected cells while improving overall resource allocation efficiency by avoiding unnecessary recovery operations in cells without beam failure.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If comprehensive beam information is transmitted, then the base station can make informed decisions, but unnecessary resource allocation occurs

Engineering Contradiction:
Improvebase station decision-making capabilityVSAvoidresource allocation waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent extracts and transmits only the necessary beam information for cells requiring recovery, removing unnecessary information that would lead to wasted resource allocation. This selective information transmission enables the base station to make informed decisions for affected cells while avoiding energy waste from processing and allocating resources for cells that do not need recovery.

Inventive Principle:
Principle #2Taking out (Extraction)
