Solution Overview

Problem

In wireless communication systems, particularly in NR systems that support both layer 2-based and layer 3-based network relays simultaneously, there is a lack of clear methods to determine the actual relay mode adopted during transmission.

Innovation Solution

A method is proposed where a relay terminal receives indication information from a network device regarding the supported relay modes, allowing it to determine whether the network device supports layer 2-based or layer 3-based network relays, and optionally sends request messages for configuration information to ensure proper relay mode configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the NR system supports both layer 2-based and layer 3-based network relays simultaneously, then the system's adaptability and versatility are improved, but the difficulty of determining the actual relay mode increases

Engineering Contradiction:
Improverelay mode supportVSAvoidrelay mode determination
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The network device sends indication information to the relay terminal to explicitly feedback which relay mode is currently active. This feedback mechanism resolves the ambiguity by providing clear information about the actual relay mode being used, allowing the relay terminal to correctly configure itself according to the network's current state.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The network device performs preliminary configuration by sending indication information about the supported relay mode before actual data transmission occurs. This preliminary action ensures that the relay terminal is pre-configured with the correct relay mode information, preventing determination difficulties during actual communication.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If the relay terminal requests configuration information for relay mode determination, then the measurement precision of relay mode is improved, but the loss of time increases

Engineering Contradiction:
Improverelay mode identificationVSAvoidconfiguration time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The network device sends indication information about the relay mode in advance, before the relay terminal needs to request configuration information. This preliminary provision of information eliminates the need for time-consuming requests and responses, as the relay terminal receives the necessary configuration information proactively.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The relay terminal autonomously determines the relay mode by processing the indication information received from the network device, without requiring complex interaction or multiple rounds of communication. This self-service approach reduces time loss by enabling the relay terminal to independently configure itself based on the received indication.

Inventive Principle:
Principle #25Self-service
