Engineering Contradiction Analysis
1Ease of operation
If all terminal devices communicate in wireless communication manner, then cabling difficulty is resolved, but resource configuration complexity increases
Solution Approach 1:
The patent segments the resource configuration process into distinct phases: resource pool determination, resource parameter acquisition, time-frequency resource determination, and resource configuration information sending. This segmentation simplifies the overall complexity by breaking down the resource management task into manageable, modular steps that can be executed systematically.
Solution Approach 2:
The patent implements preliminary action by pre-determining a resource pool before actual communication occurs. The first terminal device determines the resource pool in advance, acquires resource parameters, and prepares time-frequency resource allocations before needing to communicate with second terminal devices. This preliminary preparation reduces real-time configuration complexity during actual communication operations.
2Productivity
If resource parameters are preconfigured for all terminal devices, then resource allocation speed increases, but adaptability to different device types decreases
Solution Approach 1:
The patent applies local quality by allowing different terminal devices to acquire resource parameters according to their specific device types and capabilities. While the resource pool is determined globally by the first terminal device, individual second terminal devices can obtain customized resource parameters suitable for their specific characteristics, achieving both efficiency and adaptability.
Solution Approach 2:
The patent implements dynamics by making the resource parameter acquisition process flexible rather than static. The system allows terminal devices to dynamically acquire resource parameters based on their device types, communication requirements, and current system conditions. This dynamic approach enables the system to adapt to different device types while maintaining efficient resource allocation.

AI summary
A resource configuration method for a short-range communications field includes obtaining at least one resource parameter; determining a first time-frequency resource based on the at least one resource parameter; and sending at least one piece of resource configuration information to at least one second terminal device. The at least one piece of resource configuration information is used to configure at least one second time-frequency resource used for the at least one second terminal device, and the at least one second time-frequency resource belongs to the first time-frequency resource.
