Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network device reconfigures communication resources using broadcast signals when the network device moves and communication resources change, then the communication resource can be updated, but signaling overheads and implementation complexity increase
Solution Approach 1:
The terminal device pre-measures multiple candidate communication resources (N resources) before the network device moves. When resource change is needed, the terminal device can immediately select from pre-measured resources without waiting for reconfiguration, thus reducing signaling overhead while maintaining adaptability
Solution Approach 2:
The patent extracts the measurement and selection function from the network device to the terminal device. The terminal device independently measures and selects communication resources, removing the need for the network device to send reconfiguration broadcast signals, thereby reducing signaling overhead and implementation complexity
2Adaptability or versatility
If the network device reconfigures communication resources using broadcast signals when the network device moves and communication resources change, then the communication resource can be updated, but signaling overheads increase
Solution Approach 1:
The terminal device performs preliminary measurement on N candidate communication resources before the network device moves. This advance preparation eliminates the need for subsequent reconfiguration signaling, reducing signaling overhead while ensuring the terminal device can quickly adapt to resource changes
Solution Approach 2:
The terminal device autonomously measures, selects, and determines communication resources without requiring network device intervention or broadcast signals. This self-service approach eliminates reconfiguration signaling overhead while maintaining the ability to adapt to moving network devices

AI summary
A communication method and a related device, applicable to a non-terrestrial network (NTN) communication scenario such as a satellite network. In the method, a terminal device receives first information sent by a network device, where the first information includes N pieces of configuration information, the N pieces of configuration information are respectively used to configure N communication resources, and N is an integer greater than 1; the terminal device receives second information sent by the network device, where the second information indicates M communication resources in the N communication resources, and M is a positive integer less than or equal to N; and the terminal device measures at least one of the M communication resources.
