Sidelink Resource Selection with Assisting Device Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR technology faces challenges in efficiently managing resource usage among user equipment (UE) and assisting devices (ADs) in sidelink communications, leading to potential interference and reduced reliability due to inadequate resource exclusion techniques.
Innovation Solution
The proposed solution involves an apparatus that receives resource usage schedules from assisting nodes and devices, combines them to identify excluded resources, and transmits data on alternative resources, thereby improving resource selection and reservation techniques for sidelink communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource usage schedules from multiple assisting nodes are combined to identify excluded resources, then the reliability of sidelink communications is improved, but the device complexity increases due to additional scheduling and combination operations
Solution Approach 1:
The resource usage schedules from multiple assisting nodes are segmented and individually processed before being combined. Each assisting node's schedule is handled separately through receiving, processing, and combining operations, which manages the complexity by breaking down the overall task into manageable segments rather than processing all schedules simultaneously as a single complex operation.
2Object-affected harmful factors
If resource usage schedules are received and combined from multiple assisting nodes, then interference is reduced through accurate resource exclusion, but the loss of time increases due to additional processing steps
Solution Approach 1:
Resource usage schedules from assisting nodes are received and combined in advance before the actual sidelink transmission occurs. By performing the scheduling and resource exclusion operations preliminarily, the system identifies and excludes interfering resources beforehand, allowing the actual transmission to proceed without additional processing delays and thus reducing the overall time loss.

AI summary
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for sidelink resource selection with AD usage awareness. A UE may receive, from one or more ANs, one or more resource usage schedules associated with one or more ADs in communication with the one or more ANs. The UE may combine the one or more resource usage schedules associated with the one or more ADs into a combined resource usage schedule. The usages may be associated with the combined resource usage schedule, which may be indicative of excluded resources for a transmission of the UE. The UE may transmit, based on the combined resource usage schedule, the transmission of the UE on a resource other than the excluded resources.
