Sidelink Resource Selection via Type Information Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sidelink communication, determining the appropriate type of resources for a target resource set to be provided to another terminal device is challenging, as existing methods lack clarity on whether the resources are suitable or unsuitable for use by the receiving device, leading to inefficiencies and potential interference.
Innovation Solution
A method where a first terminal device determines type information for a target resource set to be provided to a second terminal device, ensuring the set contains either resources suitable or unsuitable for use by the second device, thereby assisting in resource selection and improving transmission reliability.

Engineering Contradiction Analysis
1Productivity
If a terminal device provides a resource set to another terminal device for resource selection, then resource selection efficiency is improved, but it is unclear whether the resources are suitable or unsuitable for use by the receiving device
Solution Approach 1:
The resource set is segmented into two distinct types: suitable resources and unsuitable resources. This segmentation allows the receiving terminal device to clearly understand which resources it can use and which it should avoid, resolving the information loss about resource suitability while maintaining efficient resource selection.
Solution Approach 2:
Instead of only providing suitable resources, the method inverts the approach by also providing unsuitable resources with explicit type information. This inverted approach ensures that the receiving device has complete information about resource suitability, preventing information loss while improving selection efficiency.
2Reliability
If resource type information is determined and provided, then resource selection reliability is improved, but device complexity increases
Solution Approach 1:
The transmitting terminal device performs preliminary action by determining the type information of resources in advance before transmission. This preliminary classification of resources into suitable and unsuitable types ensures reliable resource selection at the receiving end without requiring complex real-time analysis, thus improving reliability while managing device complexity.
Solution Approach 2:
The method changes the parameter of resource information by adding type information (suitable/unsuitable) to the resource set. This parameter enhancement improves resource selection reliability by providing clear guidance to the receiving device, while the classification process manages complexity through systematic categorization rather than complex algorithms.

AI summary
A method for wireless communication and a terminal device are provided. A first terminal device can determine type information of resources in a target resource set to be provided to a second terminal device, so that the second terminal device can perform resource selection based on the target resource set, thereby improving reliability of transmission. The method for wireless communication includes the following. A first terminal device determines type information of resources in a target resource set to be provided to a second terminal device. The target resource set is used by the second terminal device to perform resource selection. The target resource set contains at least one of: a type of resources suitable for use by the second terminal device or a type of resources unsuitable for use by the second terminal device.
