Engineering Contradiction Analysis
1Adaptability or versatility
If conventional initial access methods are used, then light terminal devices can access the system, but the transmission requirements cannot be met due to bandwidth and power limitations
Solution Approach 1:
The patent segments the initial access configuration by dividing terminal devices into different types (light terminal devices and non-light terminal devices) and providing differentiated configuration information for each type. This segmentation allows the system to tailor the access procedure to the specific capabilities of each device category, ensuring that light terminal devices with limited bandwidth and power resources receive optimized configurations that meet their transmission requirements while maintaining reliable access.
2Reliability
If differentiated configuration information is sent to light and non-light terminal devices, then transmission requirements are met, but signaling overhead increases
Solution Approach 1:
The patent implements a dynamic configuration approach where the network device determines the type of terminal device and selectively sends different configuration information based on the device type. For light terminal devices, a simplified configuration is provided that adapts to their limited capabilities, while non-light terminal devices receive comprehensive configurations. This dynamic adaptation ensures transmission requirements are met for each device type while optimizing signaling overhead by avoiding unnecessary configuration details for devices that cannot utilize them.
3Loss of information
If simplified access configuration is used for light terminal devices, then signaling overhead is reduced, but access efficiency for diverse device types deteriorates
Solution Approach 1:
The patent applies local quality by providing customized configuration information tailored to the specific needs and capabilities of different terminal device types. Light terminal devices receive simplified configurations optimized for their limited bandwidth and power resources, while non-light terminal devices receive comprehensive configurations that enable full utilization of system resources. This localized optimization ensures that each device type achieves maximum access efficiency appropriate to its capabilities, rather than using a one-size-fits-all approach that would compromise performance for either group.

AI summary
This application provides a method and an apparatus for transmitting initial access configuration information. The method includes: A first terminal device receives first information that is sent by a network device and that includes initial access configuration information corresponding to a second terminal device. Specifically, the first terminal device may obtain second information, required by the first terminal device, based on a relationship such as a difference relationship between the second information required by the first terminal device and the first information. The second information includes initial access configuration information corresponding to the first terminal device. Therefore, the network device side does not need to specially send the second information to the first terminal, and signaling overheads are reduced. In this way, transmission requirements of a plurality of types of terminal devices on initial access configuration information in different scenarios can be met.
