Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated control channel resources are allocated for different D2D communication types, then transmission quality for specific communication types is improved, but resource use efficiency deteriorates
Solution Approach 1:
The control channel resources are segmented into common control resources and dedicated control resources. Common control resources are shared by all D2D devices, while dedicated control resources are allocated only when specific communication requirements arise. This segmentation allows the system to maintain high resource efficiency while providing quality guarantees for specific communication types when needed.
Solution Approach 2:
The resource allocation is made dynamic rather than static. The network can dynamically allocate dedicated control channel resources based on real-time communication requirements, traffic conditions, and channel states. When specific communication types require enhanced quality, dedicated resources are allocated; otherwise, common resources are used, optimizing overall resource efficiency.
2Reliability
If separate control channel resources are used for first-type D2D communication, then transmission quality for first-type communication is improved, but system complexity increases
Solution Approach 1:
The control channel resource allocation mechanism is designed to be universal, supporting both common and dedicated resource modes within a unified framework. The same resource allocation procedures and signaling mechanisms are used regardless of whether common or dedicated resources are allocated, reducing system complexity while maintaining the ability to provide differentiated quality for different communication types.
3Adaptability or versatility
If dedicated control channel resources with unique physical parameter configurations are allocated, then adaptability for diverse communication types is improved, but resource configuration complexity increases
Solution Approach 1:
Different physical parameter configurations are applied locally to dedicated control channel resources based on specific communication type requirements, while common control resources use standard configurations. This allows the system to maintain simplicity for general operations while providing customized configurations for specific communication scenarios such as high-speed vehicular communication or IoT applications.

AI summary
Embodiments of the present application disclose a device-to-device (D2D) communication method, a method for assigning a D2D communication resource, and apparatuses thereof. The D2D communication method comprises: determining a usable resource in a D2D communication resource; and sending scheduling assignment (SA) information correlated to at least one D2D device by using a first control channel resource in a D2D control channel resource, wherein the first control channel resource is only used to transmit control information correlated to first-type D2D communication, and a first physical parameter configuration of the first control channel resource is different from a physical parameter configuration of another control channel resource in the D2D control channel resource. For the methods and apparatuses in the embodiments of the present application, a control channel resource independent of other D2D communication is used, so that at the same time when transmission quality of specific-type D2D communication is improved, use efficiency as the specific-type D2D communication and other D2D communication coexist on a spectrum resource is improved.
