Network Relay for Wireless Data Delivery Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In densely populated areas, existing wireless communication systems face network overload due to increased user demand, leading to poor user experience as terminal devices may not receive data from network devices with small coverage areas, especially when they are in motion or experience downlink channel quality issues.
Innovation Solution
A method where a first network device, supporting a first radio access technology, negotiates with a second network device, supporting a second radio access technology, to send target data including radio resource indication information, system information, RRC layer data, or MAC layer data to terminal devices, ensuring communication even if the terminal device cannot directly receive from the second network device.

Engineering Contradiction Analysis
1Productivity
If a second network device with small coverage is deployed within the first network to reduce load, then network overload is alleviated, but terminal devices may fail to receive data due to movement or channel quality issues
Solution Approach 1:
The first network device acts as an intermediary between the second network device and terminal devices. It receives data from the second network device, performs protocol conversion and repackaging, then forwards it to terminal devices through the first RAT. This mediator approach allows terminal devices to access the second network's data stream indirectly, ensuring reliable reception even when direct access to the second network device is unavailable due to movement or channel quality issues.
2Area of stationary object
If the first network device sends data directly to terminal devices using the first RAT, then coverage is expanded and access is simplified, but network overload occurs in densely populated areas
Solution Approach 1:
The patent merges the coverage advantage of the first RAT with the capacity advantage of the second RAT. The first network device maintains wide coverage using the first RAT while simultaneously leveraging the high-capacity second network device for data delivery. By combining these two networks' strengths through protocol conversion and coordinated data transmission, the system achieves both expanded coverage and enhanced network capacity.
3Reliability
If a second network device with small coverage is deployed to improve service quality, then user experience is enhanced, but terminal devices in motion or with poor channel quality cannot access the second network
Solution Approach 1:
The first network device performs multiple functions: it maintains wide coverage for all terminal devices, manages protocol conversion between first and second RATs, and acts as a relay for data from the second network device. This multi-functional approach ensures that terminal devices regardless of their mobility state or channel quality can access services through the universal first network device, which in turn accesses the high-quality second network when appropriate.

AI summary
A method and an apparatus for wireless communication are provided. The method includes: negotiating, by a first network device, with a second network device to determine target data, where the first network device supports wireless communication based on a first radio access technology RAT, and the second network device supports wireless communication based on a second RAT; and sending, by the first network device based on the first RAT to a terminal device, the target data and RAT type indication information that is used to indicate the second RAT. In this way, user experience can be improved.
