Initial Access Bandwidth Part Configuration for Low-Capability Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminals with poor capabilities fail to work normally due to initial access bandwidth parts configured by the access network device exceeding their capabilities, as indicated by RMSI in existing communication systems.
Innovation Solution
A method for determining an initial access bandwidth part by a first terminal based on a first rule that does not exceed its access bandwidth capability, and a method for configuring RMSI to include separate configuration information for terminals with different capabilities, ensuring the initial access bandwidth part aligns with the terminal's capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the access network device configures the initial access bandwidth part through RMSI, then the system can provide initial access functionality, but terminals with poor capabilities cannot work normally because the configured bandwidth exceeds their capabilities
Solution Approach 1:
The patent segments the initial access bandwidth part configuration by introducing separate configuration parameters for different terminal capability levels. Specifically, it defines first initial access bandwidth part configuration for terminals with poor capabilities and second initial access bandwidth part configuration for terminals with normal capabilities, allowing the system to provide appropriate configurations based on terminal capabilities
Solution Approach 2:
The patent applies local quality by providing different configuration qualities to different terminal types. Terminals with poor capabilities receive a restricted initial access bandwidth part configuration that ensures reliable operation, while terminals with normal capabilities receive a more comprehensive configuration, optimizing performance for each terminal category
2Device complexity
If a single initial access bandwidth part configuration is provided for all terminals, then the configuration process is simple, but terminals with different capabilities cannot both operate optimally
Solution Approach 1:
The patent introduces dynamic configuration selection based on terminal capability indication. The access network device determines terminal capability level and dynamically selects the appropriate initial access bandwidth part configuration, making the system adaptable to different terminal types without requiring complex manual configuration for each terminal
Solution Approach 2:
The patent changes the configuration parameters by introducing capability-based differentiation. It defines specific parameter sets (first configuration for poor capability terminals, second configuration for normal capability terminals) that modify the initial access bandwidth part characteristics based on terminal capabilities, allowing optimized performance across different terminal types

AI summary
A method for determining an initial access bandwidth part, includes: determining, by a first terminal, a first initial access bandwidth part based on a first rule, wherein the first initial access bandwidth part does not exceed an access bandwidth capability of the first terminal, the access bandwidth capability of the first terminal is lower than an access bandwidth capability of a second terminal, and the second terminal is a terminal that determines a second initial access bandwidth part based on a second rule according to remaining minimum system information (RMSI), and wherein the first rule and the second rule are not completely identical or are completely different.
