NTN Wireless Node Default Configuration Indexing

Solution Overview

Problem

Existing wireless communication systems in non-terrestrial networks (NTNs) face inefficiencies due to an undesired number of transmissions and bits required for configuring user equipment (UE), leading to increased latency, reduced throughput, and higher power consumption.

Innovation Solution

The proposed solution involves a method where a wireless communication node configures a list of default configurations associated with indices and provides these indices to the UE, allowing the UE to apply the corresponding default configurations efficiently, thereby reducing the number of transmissions and bits required.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If detailed configuration information is transmitted to UE in NTN, then configuration accuracy is improved, but transmission overhead and latency increase

Engineering Contradiction:

Improveconfiguration accuracyVSAvoidlatency

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The network pre-configures multiple default configuration sets with different parameters (e.g., different numbers of repetitions, different payload sizes) and assigns each set an index. The UE stores these pre-configured options locally, so during actual communication, the network only needs to transmit an index rather than the entire configuration, dramatically reducing transmission overhead and latency while maintaining configuration accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of transmitting the full configuration information repeatedly, the system creates compact copies in the form of configuration indexes that reference pre-stored configuration templates. The UE receives and applies the configuration by copying the referenced template, which reduces the amount of data that needs to be transmitted over the air interface.

Inventive Principle:

Principle #26Copying
