NR Sidelink Auxiliary Resource Timing Before Validity Expiry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the enhancement of new radio (NR) Sidelink Mode 2, the auxiliary resource set sent by one user equipment to another may become outdated before it can be used, leading to inefficiencies and reduced communication performance.
Innovation Solution
The method involves determining a window end time domain position for the resource selection window based on a specified time domain position offset, ensuring that the auxiliary resource set is sent and received before it becomes outdated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the auxiliary resource set is sent using traditional resource selection window, then the resource selection process can be completed, but the auxiliary resource may become outdated before being used
Solution Approach 1:
The patent applies preliminary action by calculating and determining the window end time domain position in advance, before the auxiliary resource set transmission begins. This pre-determined time boundary ensures that the resource selection window closes before the auxiliary resource becomes outdated, preventing the use of expired resources while maintaining the feasibility of resource selection.
2Adaptability or versatility
If the resource selection window is extended to accommodate later transmission, then transmission flexibility is improved, but outdated resources may be selected
Solution Approach 1:
The patent implements dynamics by making the resource selection window time-boundary adaptive rather than fixed. The window end time domain position is dynamically calculated based on the current time and the validity period of the auxiliary resource, allowing the system to adjust the transmission timing window to match the resource validity window while preventing outdated resource selection.
3Reliability
If the auxiliary resource set is transmitted immediately, then resource validity is maintained, but transmission timing constraints are reduced
Solution Approach 1:
The patent applies parameter changes by introducing a calculated time parameter (window end time domain position) that transforms the transmission timing from an immediate or fixed constraint to a dynamically adjusted parameter. This parameter is derived from the current time and resource validity period, allowing the system to maintain resource validity while providing controlled timing flexibility without excessive complexity.

AI summary
The present disclosure relates to an auxiliary resource set-based communication method and apparatus, and a storage medium. The auxiliary resource set-based communication method is executed by a first user equipment and comprises: determining a window end time domain position of a resource selection window, the resource selection window being a time window for the first user equipment to send an auxiliary resource set to a second user equipment, and the window end time domain position being determined on the basis of a specified time domain position offset; and sending the auxiliary resource set to the second user equipment on the basis of the window end time domain position. The present disclosure can alleviate the situation that auxiliary resources cannot be used because the auxiliary resources are outdated due to the fact that the auxiliary resources indicated by the auxiliary resource set are received after the window end time domain position.
