Solution Overview

Problem

In mobile communication systems, when a User Equipment (UE) initiates a 2-step Random Access (RA) process, especially in scenarios where the UE is not connected to the network or the connection is interrupted, the network side lacks necessary information to configure optimal random access parameters, leading to difficulties in efficient resource allocation and increased failure rates.

Innovation Solution

The UE records and transmits 2-step RA related information, including state, resource configurations, and quality metrics to the network, enabling the network to optimize random access parameters and improve communication performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the 2-step RA process is used to reduce delay and interaction steps, then access speed is improved, but the network side cannot reasonably configure random access parameters because it lacks information about UE state

Engineering Contradiction:

Improveaccess speedVSAvoidnetwork lacks UE state information

Core Design Contradiction:

SpeedVSLoss of information

Solution Approach 1:

The UE records 2-step RA related information (including UE state, scenario, resource configurations, and quality metrics) before accessing the network. This preliminary recording action ensures that when the UE initiates the 2-step RA process, the network can obtain these pre-recorded information to configure appropriate parameters, thus maintaining both fast access speed and informed parameter configuration

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The UE transmits the recorded 2-step RA related information to the network as feedback. This feedback mechanism allows the network to understand the UE's state and conditions, enabling the network to configure reasonable random access parameters while maintaining the fast 2-step RA process

Inventive Principle:

Principle #23Feedback

2Manufacturing precision

If the UE transmits detailed 2-step RA related information to the network, then parameter configuration accuracy is improved, but signaling overhead increases

Engineering Contradiction:

Improveparameter configuration accuracyVSAvoidsignaling overhead

Core Design Contradiction:

Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent extracts only the most essential 2-step RA related information (UE state, scenario, resource configurations, and quality metrics) that the network needs for parameter configuration. By selecting and transmitting only these critical parameters rather than all possible information, the solution achieves accurate parameter configuration while minimizing signaling overhead
