D2D Resource Configuration via Terminal Sensing Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the Internet of Vehicles (IoV) communication system, there is a conflict in resource allocation between terminal devices using transmission mode 3 and mode 4 in D2D communications, leading to interference, as the network device is unaware of the resource occupation status in the shared resource pool.
Innovation Solution
The terminal device performs resource sensing based on specific transmission parameters, determines an available resource set, and reports it to the network device, assisting in allocating transmission resources to reduce interference.

Engineering Contradiction Analysis
1Productivity
If a resource pool is shared by terminal devices using transmission mode 3 and mode 4, then resource utilization is improved, but interference occurs due to resource allocation conflicts
Solution Approach 1:
The terminal device performs resource sensing to detect the occupation status of resources in the shared resource pool, and feeds back this information to the network device. The network device uses this feedback to adjust resource allocation decisions, avoiding allocation of resources that are already occupied by mode 4 terminal devices, thereby reducing interference while maintaining high resource utilization
Solution Approach 2:
The terminal device performs resource sensing in advance before resource allocation to identify occupied resources. This preliminary detection allows the network device to make informed allocation decisions that avoid conflicts with mode 4 terminal devices, preventing interference before it occurs
2Productivity
If the network device allocates resources to terminal devices using transmission mode 3, then resource allocation efficiency is improved, but the network device cannot avoid conflicts with mode 4 terminal devices due to lack of awareness of resource occupation status
Solution Approach 1:
The terminal device performs resource sensing to detect the occupation status of resources and feeds back this information to the network device. This feedback mechanism enables the network device to make accurate resource allocation decisions that avoid conflicts with mode 4 terminal devices, thereby improving both allocation efficiency and accuracy
Solution Approach 2:
The resource sensing information acts as an intermediary that bridges the network device and mode 4 terminal devices. By obtaining and utilizing this intermediate information, the network device can make informed allocation decisions that avoid conflicts, improving both efficiency and accuracy of resource allocation
