Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in managing connections between remote terminals and relay terminals when using non-3GPP protocols, such as wired or WLAN connections, due to the lack of effective connection management methods.
Innovation Solution
A wireless communication method and devices that enable connection management, including establishment, release, and resumption of relay connections by acquiring and transmitting information related to the connection between terminals via non-3GPP interfaces, allowing network devices to manage these connections effectively.

Engineering Contradiction Analysis
1Productivity
If the same time resource is allocated for downlink and uplink transmissions in TDD mode, then the time resource utilization is improved, but the downlink control information cannot be transmitted in time for uplink feedback
Solution Approach 1:
The patent segments the time resource allocation by introducing a dedicated first time resource for downlink control information transmission and a second time resource for uplink feedback transmission. This segmentation allows the control information to be sent before the uplink data transmission, resolving the timing conflict while maintaining efficient resource utilization.
Solution Approach 2:
The patent applies preliminary action by transmitting the downlink control information in the first time resource before the uplink feedback transmission in the second time resource. This preliminary transmission of control information ensures that the uplink feedback can be sent in time without delaying the overall communication process.
2Productivity
If FDD mode is used for simultaneous downlink and uplink transmissions, then the time resource utilization is improved, but the device complexity increases due to requiring both TDD and FDD modes
Solution Approach 1:
The patent makes the time resource allocation method universal by demonstrating that it can be applied to both TDD and FDD communication modes. The method provides a flexible framework that works across different modes without requiring separate complex configurations for each mode, thereby reducing overall device complexity while maintaining high time resource utilization.
3Productivity
If downlink control information is transmitted in the same time resource as uplink feedback, then the time resource utilization is improved, but the feedback timing cannot be guaranteed
Solution Approach 1:
The patent segments the time resources into distinct first and second time resources for downlink control information and uplink feedback respectively. This segmentation guarantees that the feedback timing is met by ensuring sufficient time separation between control information transmission and feedback transmission, while still maintaining efficient overall time resource utilization.

AI summary
A wireless communication method, a network device and a terminal device are provided. The method includes: acquiring, by a network device, target information, where the target information is information related to a connection between a first terminal and a second terminal; where the first terminal and the second terminal are connected via a first interface, and the first interface is not an interface defined by a 3rd generation partnership project (3GPP) protocol.
