Relay Mode Determination in NR Wireless Networks
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
