Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face high power consumption due to the need for frequent transmission of common signals by network devices to enable terminal devices to identify and access cells, hindering long-term radio frequency channel shutdown and energy saving.
Innovation Solution
A method where network devices send common configurations of multiple cells in a centralized manner, allowing terminal devices to determine configurations based on received configurations, reducing signaling overheads and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If common signals are sent frequently in each cell, then terminal devices can identify and access cells timely, but signaling overheads increase and power consumption rises
Solution Approach 1:
The patent merges common signal transmissions for multiple cells into a single centralized transmission. Instead of each cell transmitting its own common signals independently, the network device sends common signals for multiple cells through one cell, thereby reducing redundant transmissions and lowering power consumption while ensuring terminal devices can still access any cell in the group.
Solution Approach 2:
The patent implements multi-functionality by enabling a single cell to serve multiple purposes: it not only provides its own common signals but also transmits common signals for other cells in the group. This universal approach allows the network device to reduce the number of active transmission channels while maintaining comprehensive cell coverage and access capability.
2Use of energy by moving object
If common signals of multiple cells are sent in one cell in a centralized manner, then power consumption is reduced, but signaling overheads increase
Solution Approach 1:
The patent segments the common signal transmission task by dividing cells into groups where each group shares a common signal transmission resource. This segmentation allows the network to reduce overall signaling overhead by eliminating redundant transmissions across cell boundaries while maintaining individual cell identity and access functionality through configured associations.

AI summary
A communication method is provided. The method includes: A network device sends, in a first cell, common configurations of M cells and dedicated configurations of N cells of the M cells, where the N cells do not include the first cell; and a terminal device determines cell configurations of the N cells based on the common configurations of the M cells and the dedicated configurations of the N cells. In this manner, the cell configurations of the N cells are compressed, so that signaling overheads of the network device can be reduced, implementing energy saving of the network device.
