Initial Access Configuration for Light NR Terminal Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional initial access methods in new radio (NR) systems fail to meet the complex transmission requirements of light terminal devices with smaller bandwidth and lower power consumption.
Innovation Solution
A method for transmitting initial access configuration information involves a first terminal device receiving information from a network device and determining additional information based on predefined or known parameters, such as offsets or correspondences, to reduce signaling overheads and accommodate different types of terminal devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional initial access methods are used, then the transmission requirements for light terminal devices are not met, but the system can still operate with standard terminal devices
Solution Approach 1:
The patent applies local quality by providing different initial access configuration information tailored to different terminal device types. The network device determines whether to send first initial access configuration information (for second terminal devices) or second initial access configuration information (for first terminal devices) based on device characteristics, allowing customized configuration for light terminal devices with smaller bandwidth while maintaining standard configuration for conventional devices.
Solution Approach 2:
The patent implements dynamics by making the initial access configuration adaptive and changeable based on terminal device type. The network device dynamically selects and sends appropriate configuration information (first or second) according to the capabilities of the accessing terminal, enabling the system to adapt to varying device requirements rather than using a fixed configuration approach.
2Adaptability or versatility
If separate initial access configuration information is sent for different terminal device types, then adaptability improves, but signaling overhead increases
Solution Approach 1:
The patent extracts only the necessary differentiated configuration information for light terminal devices rather than transmitting complete separate configurations. By identifying and sending only the specific initial access configuration parameters that differ for first terminal devices (with smaller bandwidth), the system reduces signaling overhead while still providing tailored support for different device types.
Solution Approach 2:
The patent applies partial action by sending only the essential initial access configuration information needed for light terminal devices to function, rather than transmitting full configuration sets. The network device sends minimal differentiated parameters (first initial access configuration information) that enable light terminal devices to operate with their smaller bandwidth capabilities without overwhelming them with unnecessary configuration data.

AI summary
This application provides a method and an apparatus for transmitting initial access configuration information. The method includes: a first terminal device receiving first information that is sent by a network device and that includes initial access configuration information corresponding to a second terminal device. 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.
