Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless communication systems lack support for recording and optimizing random access (RA) resource configurations for multiple feature combinations, leading to potential mismatches between terminal capabilities and network resource allocations.

Innovation Solution

A terminal records feature information applicable to RA, such as SDT, RedCap, and RAN slicing, and reports this information to the network device, enabling the network device to optimize RA resource configurations accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the network device configures RA resources without recording terminal capability information, then the configuration process is simple, but the availability and effectiveness of RA resource configurations deteriorates

Engineering Contradiction:

Improveavailability of RA resource configurationsVSAvoidcomplexity of terminal operations

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The terminal autonomously determines and records its own capability information (SDT, RedCap, RAN slicing) without requiring network configuration or complex manual setup. The terminal self-identifies its features and stores them for later use in RA resource selection, eliminating the need for network-side configuration of terminal capabilities.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The terminal performs capability recording in advance before actual RA resource selection is needed. By pre-determining and storing capability information, the terminal prepares necessary data ahead of time, enabling efficient RA resource configuration without adding complexity during the actual communication process.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If the terminal records feature information for RA, then the alignment between terminal capabilities and network resources is improved, but the operational complexity increases

Engineering Contradiction:

Improvealignment of terminal capabilities and network resourcesVSAvoidoperational simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The terminal automatically determines its own capability information (SDT, RedCap, RAN slicing) and records it without requiring user intervention or complex configuration procedures. This self-service approach maintains operational simplicity while achieving capability-network alignment.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The terminal uses the recorded capability information as feedback to guide its RA resource selection process. By continuously referring to its own capability records, the terminal ensures alignment with network resources without requiring complex external configuration or manual adjustment.

Inventive Principle:
