Merging 5G Control Channels for Multi-Numerology Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G communication systems face inefficiencies due to the need for multiple common control channels across different numerologies, leading to increased overhead, resource waste, and higher complexity and power consumption in terminal devices as they search for and transmit common control channels across various numerologies.
Innovation Solution
A method where a network device sends configuration information for multiple numerologies through a single control channel, allowing terminal devices to receive this information without needing to search for separate common control channels in each numerology, thereby reducing overhead and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a common control channel is transmitted in the resource of each numerology, then the configuration information for each numerology can be indicated, but the overhead of common control channels increases and system resources are wasted
Solution Approach 1:
The patent merges the common control channels of multiple numerologies into a single common control channel. The network device transmits configuration information for multiple numerologies (including second numerology) through a first common control channel in the resource of the first numerology, eliminating the need for separate common control channels in each numerology and reducing overhead.
Solution Approach 2:
The first common control channel serves multiple functions by indicating configuration information for multiple numerologies simultaneously. It not only indicates configuration for the first numerology but also provides configuration information for the second numerology and other numerologies, making a single channel universal across different numerologies.
2Loss of information
If a terminal searches for common control channels in the resource of each numerology, then the configuration information can be obtained, but the complexity and power consumption of the terminal increase
Solution Approach 1:
The patent merges the search process into a single location. The terminal device only needs to search for and receive the first common control channel in the resource of the first numerology, which contains configuration information for multiple numerologies, eliminating the need to search across multiple numerology resources.
Solution Approach 2:
The first common control channel serves as a universal information source for multiple numerologies. The terminal device receives configuration information for the first numerology and other numerologies through this single common control channel, making one channel sufficient for multiple purposes.

AI summary
Provided are an information transmission method, a network device and a terminal device. The method includes: a network device sends first configuration information to a terminal device through a first control channel, wherein the first control channel is a control channel in a resource for which a first numerology is used, the first configuration information is used for indicating configuration in a resource for which a second numerology is used, and the first numerology is different from the second numerology.
