Terminal Resource Sensing and Reporting for D2D
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing resource sensing and reporting methods in terminal devices, as defined in Release 14, are inadequate to meet the higher requirements of Release 15 and later communication standards, particularly in terms of adaptability and efficiency for D2D communication systems like the Internet of Vehicles.
Innovation Solution
The method allows terminal devices to flexibly select and report wireless time-frequency resources by determining their own sensing and reporting methods, enabling them to provide measurement results to network devices for improved resource scheduling, which includes configuring indices for time, frequency, and resource availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminal devices use the resource sensing and reporting methods defined in Release 14, then the implementation is simple and follows existing standards, but the methods cannot meet the higher requirements of Release 15 and later communication standards
Solution Approach 1:
The patent enables terminal devices to dynamically select between different resource sensing and reporting methods based on network configuration and communication requirements. The terminal can switch between autonomous resource selection and network-scheduled resource reporting, making the system adaptive to different Release versions and traffic conditions while managing complexity through flexible configuration.
2Ease of operation
If terminal devices autonomously select and report resources without network scheduling, then the resource allocation flexibility is improved, but the resource allocation efficiency and spectrum utilization may deteriorate
Solution Approach 1:
The patent implements a two-stage approach where the network device first pre-configures resource pools and parameters for terminal devices, then terminals autonomously select specific resources from these pre-defined pools. This preliminary network configuration ensures efficient and fair resource distribution while allowing terminals operational flexibility in selecting actual transmission resources.
3Measurement precision
If terminal devices perform comprehensive resource sensing across all available resources, then the resource selection accuracy is improved, but the sensing time and energy consumption increase
Solution Approach 1:
The patent enables terminal devices to focus resource sensing efforts on locally relevant resources within configured resource pools rather than scanning all system resources. The network configures specific resource pools with particular time-frequency characteristics suitable for each terminal's communication needs, allowing accurate resource selection with reduced sensing scope and lower time-energy cost.

AI summary
Embodiments of the present application provide a resource reporting method, a terminal device, and a network device. The terminal device may select a resource to listen to, and select a resource to report. In addition, the resource listening approach and the resource reporting approach can be flexibly determined. Therefore, the communication requirements of Release 15 or higher releases can be satisfied. The method comprises: a terminal device reports to a network device the measurement result of a first wireless time-frequency resource used for terminal-to-terminal communication, wherein the terminal device is a terminal device supporting a network scheduling mode of a terminal-to-terminal communication resource.
