Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sidelink resources are supported for different sidelink services, then resource utilization and service flexibility are improved, but the complexity of determining how to use these resources increases
Solution Approach 1:
The patent applies preliminary action by having the first terminal determine a target sidelink resource from multiple candidate resources before actual communication begins. The network side device or second terminal provides configuration indication information that pre-specifies which resource should be used, eliminating the need for real-time complex decision-making during communication.
Solution Approach 2:
The patent introduces configuration indication information as an intermediary mechanism between the available resources and the selection process. This intermediary carries instructions from the network side device or second terminal that guide the first terminal's resource selection, simplifying the complexity of managing multiple resources.
2Adaptability or versatility
If multiple sidelink resources are supported, then service execution capability is improved, but data loss risk increases due to unclear resource allocation
Solution Approach 1:
The patent ensures reliable data transmission by performing preliminary resource determination before communication starts. The target sidelink resource is selected and configured in advance based on configuration indication information, ensuring both terminals agree on the correct resource and eliminating data loss due to resource ambiguity.
Solution Approach 2:
The patent implements feedback through the configuration indication information mechanism, where the network side device or second terminal provides feedback about which resource should be used. This feedback loop ensures that the first terminal selects the correct resource, preventing data loss and ensuring reliable communication.
3Adaptability or versatility
If multiple sidelink resources are supported, then communication flexibility is improved, but energy consumption increases due to monitoring multiple resources
Solution Approach 1:
The patent extracts the resource selection burden from the terminal by having the network side device or second terminal provide configuration indication information that specifies the target resource. This extraction reduces the terminal's energy consumption by eliminating the need to actively monitor and evaluate multiple candidate resources for selection.
Solution Approach 2:
The patent applies self-service by having the first terminal simply follow the configuration indication information provided by the network side device or second terminal. The terminal doesn't need to independently analyze multiple resources, saving energy while still achieving flexible communication.

AI summary
Disclosed in embodiments of the present disclosure are a Sidelink communication method, an apparatus, and a storage medium, which can be applied to systems such as Internet of Vehicles, V2X and V2V. The method is performed by a first terminal, and comprises: receiving configuration indication information sent by a network side device or a second terminal; and determining, according to the configuration indication information, a target Sidelink resource used for Sidelink transmission among a plurality of candidate Sidelink resources. Therefore, when the first terminal and the second terminal execute a Sidelink service, the Sidelink transmission is performed on the determined target Sidelink resource, so that the execution of the Sidelink service can be ensured, data loss is avoided, energy consumption can be saved, and resource waste can be avoided.
