Sidelink Resource Scheduling for Terminal Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sidelink communication systems, terminal devices lack the ability to autonomously perform resource scheduling, relying on network devices for resource allocation, which can lead to network pressure and inefficient resource management.
Innovation Solution
A method and apparatus that enable terminal devices to request sidelink resource scheduling from a network device, allowing them to perform resource scheduling within a user group based on assigned configuration information, thereby reducing network pressure and improving resource allocation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If terminal devices rely on network devices for resource allocation, then resource scheduling can be centralized managed, but network pressure increases and terminal devices lose autonomous scheduling capability
Solution Approach 1:
The patent divides the resource scheduling function into two segments: network devices allocate resource pools to terminal devices, while terminal devices autonomously schedule resources within their allocated pools. This segmentation reduces network device burden while enabling terminal device autonomy.
Solution Approach 2:
Terminal devices are enabled to self-manage resource scheduling within their allocated pools without continuous network intervention. The patent implements this by allowing terminal devices to autonomously select and manage resources based on their communication needs, reducing dependency on network devices.
2Ease of operation
If network devices allocate resources to terminal devices, then resource allocation can be controlled centrally, but terminal devices cannot autonomously perform resource scheduling
Solution Approach 1:
The scheduling function is segmented between network and terminal devices. Network devices perform high-level resource pool allocation, while terminal devices handle low-level autonomous scheduling within their pools. This segmentation improves both terminal autonomy and overall system efficiency.
Solution Approach 2:
The patent implements dynamic resource scheduling where terminal devices can flexibly allocate resources within their pools based on real-time communication needs. This dynamic approach improves resource allocation efficiency while maintaining terminal device autonomy.
3Extent of automation
If terminal devices autonomously select resources from resource pools, then terminal device autonomy is achieved, but resource allocation may be less optimized compared to network-controlled scheduling
Solution Approach 1:
The patent segments scheduling responsibilities: network devices ensure overall resource distribution and pool allocation (providing optimization), while terminal devices handle autonomous selection within pools (providing autonomy). This segmentation achieves both goals simultaneously.
Solution Approach 2:
Network devices perform preliminary resource pool allocation to terminal devices before terminal devices need to schedule resources. This preliminary action ensures optimized resource distribution is established in advance, allowing terminal devices to autonomously schedule without compromising overall optimization.

AI summary
The present disclosure relates to a method and apparatus for requesting scheduling sidelink resources, and a storage medium. The method is applied to a terminal device, and includes: sending a sidelink terminal message to a network device, wherein the sidelink terminal message comprises a request initiated by the terminal device for performing sidelink resource scheduling by the terminal device; receiving a response message corresponding to the sidelink terminal message sent by the network device; in response to that the response message is a first response message indicating that the request from the terminal device is approved, obtaining assigned sidelink resource configuration information from the first response message; and performing sidelink resource scheduling for respective terminal devices within a user group including the terminal device based on the assigned sidelink resource configuration information.
