Publication number: 20240121760Abstract: A first wireless device may communicate with a second wireless device using sidelink resources. Some of the sidelink resources may be allocated for communications using transmissions via multiple slots (e.g., multiple consecutive slots). A size of the multiple slots for the transmission may be determined based on a size threshold of the multiple slots, an amount of data to be sent, and/or a quantity of consecutive sidelink resources in available sidelink resources.Type: ApplicationFiled: September 29, 2023Publication date: April 11, 2024Inventors: Huifa Lin, Hyoungsuk Jeon, Esmael Hejazi Dinan, Bing Hui, Nazanin Rastegardoost
