PBCH and SSB Signaling for High-Band NR Initial Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in the New Radio (NR) system is determining the meaning of information transmitted in the PBCH and SSB transmission in high-frequency bands, particularly in unlicensed spectra, where multiple candidate positions and new subcarrier spacings are required, complicating the initial access procedure.
Innovation Solution
The network device sends information such as SSB or SIB1 to the terminal device based on the high-frequency band, enabling the terminal device to determine subcarrier spacing, subcarrier offset, and QCL hypothesis indication, facilitating access to the network for data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a camera and various sensors are mounted on a mobile body to acquire image data and sensor data, then the capability to collect comprehensive information is improved, but the weight and complexity of the mobile body increase
Solution Approach 1:
The patent introduces a server as an intermediary device that stores and manages reference data (image data, sensor data, point cloud data) externally. The mobile body only needs to transmit identification information to the server, which then retrieves and provides the relevant data. This mediator approach allows comprehensive information collection without burdening the mobile body with heavy onboard storage and processing equipment.
Solution Approach 2:
The patent creates digital copies of reference data (image data, sensor data, point cloud data) and stores them on the server. Instead of requiring the mobile body to carry original heavy equipment for each type of data collection, the system uses copied data from the server. This allows the mobile body to access comprehensive information while maintaining lightweight hardware.
2Loss of information
If multiple types of data (image data, sensor data, point cloud data) are stored and managed locally on the mobile body, then data availability is improved, but the device complexity and processing burden increase
Solution Approach 1:
The patent extracts the complex data storage and management functions from the mobile body and places them on an external server. The mobile body only retains lightweight functions for transmitting identification information and receiving processed results. This extraction principle separates the complex data management burden from the mobile platform while maintaining full data availability through server access.
Solution Approach 2:
The server provides universal data management services that can handle multiple types of data (image data, sensor data, point cloud data) through a single unified system. Instead of requiring the mobile body to implement separate specialized systems for each data type, the universal server handles all data types, reducing the complexity on the mobile body while maintaining comprehensive data availability.
3Weight of moving object
If reference data is stored on a server and transmitted to the mobile body as needed, then the weight of the mobile body is reduced, but the response time and data transmission requirements increase
Solution Approach 1:
The patent implements preliminary action by pre-storing all necessary reference data (image data, sensor data, point cloud data) on the server in advance. When the mobile body needs data, it only needs to transmit identification information, and the server can quickly retrieve the pre-prepared data without requiring complex real-time processing or transformation. This preliminary preparation reduces the actual data retrieval time despite the external storage location.
