  • SIDELINK RESOURCE SELECTION BASED ON USER EQUIPMENT COORDINATION
    Publication number: 20230292347
    Abstract: A method for selecting resources for a transmission between a first UE and a second UE is disclosed. A set of coordination resources is determined at the first UE. The set of coordination resources includes coordination information which may indicate whether the set of coordination resources are preferred resources and/or non-preferred resources. The set of coordination resources is sent to the second UE, and the second UE takes the coordination information into account in the resource selection for its own transmission. For example, the resource selection by the second UE may be based on both the sensing result of the second UE and the received coordination information from the first UE. Alternatively, there source selection by the second UE may be based exclusively or non-exclusively on the received coordination information from the first UE.
