Solution Overview
Problem
Current coverage enhancement methods in terrestrial networks are inadequate to meet the increased coverage requirements of non-terrestrial networks due to the longer propagation distances in satellite systems.
Innovation Solution
A method for determining the number of repeated transmissions in non-terrestrial networks by using a first parameter that includes a set of repeated transmission times or a list of repeated transmission times specifically set for non-terrestrial networks, and optionally using offset values to adjust the number of repeated transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current coverage enhancement methods in terrestrial networks are used, then the methods are simple to implement, but they cannot meet the coverage enhancement requirements in non-terrestrial networks due to long propagation distances
Solution Approach 1:
The patent implements dynamic adaptation by introducing a switchable mechanism that allows the system to select between terrestrial network parameters and non-terrestrial network parameters based on the network type. The network device can dynamically configure and indicate different parameter sets (first parameters for NTN, second parameters for TN) to terminal devices, enabling the same coverage enhancement method to adapt to both terrestrial and non-terrestrial network environments with different propagation characteristics
Solution Approach 2:
The patent changes the parameters used for coverage enhancement by introducing a first parameter set specifically designed for non-terrestrial networks with different propagation characteristics. The network device configures and indicates these modified parameters (such as adjusted repeated transmission times, power levels, or resource allocations) to terminal devices, allowing the system to optimize coverage enhancement for satellite-based networks while maintaining compatibility with terrestrial networks through parameter selection
2Reliability
If the number of repeated transmissions is increased to meet NTN coverage requirements, then coverage enhancement is improved, but system resource consumption and complexity increase
Solution Approach 1:
The patent segments the parameter configuration by creating distinct first parameters for non-terrestrial networks and second parameters for terrestrial networks. This segmentation allows the system to apply appropriate parameter sets based on network type, avoiding the unnecessary complexity of handling all parameter variations in a single unified configuration. The network device and terminal device are divided into functional modules that separately process NTN-specific and TN-specific parameters

AI summary
The present disclosure provides a method for determining a number of repeated transmissions, an apparatus and a storage medium. The method includes: receiving first indication information, where the first indication information is used to indicate use of a first parameter to determine the number of repeated transmissions; determining a first number of repeated transmissions by using the first parameter. The first indication information is received, and according to the indication of the first indication information, the first number of repeated transmissions is determined by using the first parameter. Because the first parameter in the embodiments is a parameter set to meet greater coverage enhancement requirements, the first number of repeated transmissions determined by using the first parameter can ensure that repeated transmission requirements of an NTN network are met, thereby further ensuring greater coverage enhancement requirements of the NTN network.
