Solution Overview

Problem

Current wireless communication systems face challenges in effectively managing and allocating resources across multiple independent links, which are essential for efficient communication in multi-user, multi-beam scenarios, particularly in 5G and mmW systems, where links operate independently and require distinct resource management.

Innovation Solution

The solution involves determining interactions between multiple wireless communication links and dynamically allocating resources based on these interactions, enabling independent processing and management of each link, including channel sensing, control information transmission, power control, and beam management across multiple links.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If multiple independent wireless communication links are managed with unified resource allocation, then system complexity is reduced, but communication efficiency and reliability deteriorate due to inability to optimize each link independently

Engineering Contradiction:
Improveresource management complexityVSAvoidcommunication efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent segments resource allocation into link-specific allocations, where each wireless communication link receives dedicated resource allocation independently. The network device determines resource allocation for first resources associated with a first link and second resources associated with a second link separately, allowing each link to be optimized independently while maintaining manageable system complexity through structured segmentation.

Inventive Principle:
Principle #1Segmentation

2Productivity

If resources are allocated independently for each link, then communication efficiency improves, but system complexity and coordination overhead increase

Engineering Contradiction:
Improvelink utilization efficiencyVSAvoidresource allocation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements segmentation by dividing resource allocation into distinct link-specific allocations. The network device performs independent resource allocation for each wireless communication link, determining first resources for the first link and second resources for the second link separately. This segmentation enables efficient link-specific optimization while maintaining manageable complexity through structured organization of allocation processes.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If beam information is transmitted only on the affected link, then link independence is maintained, but communication reliability deteriorates due to lack of backup transmission paths

Engineering Contradiction:
Improvelink independenceVSAvoidbeam information delivery reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies multi-functionality by enabling a single link to serve multiple purposes: it functions as both a data transmission link and a control information transmission link for other links. Specifically, first resources on the first link can carry beam information related to the second link, allowing the first link to universally handle both its own control information and control information for the second link, thereby improving reliability through redundant transmission paths while maintaining link independence.

Inventive Principle:
Principle #6Universality (Multi-functionality)
