## Abstract

Various embodiments disclosed herein provide for facilitating updating of slot format used for establishing the new radio sidelink. According an embodiment, a system can receiving a slot format over a sidelink, wherein the slot format comprises a first release parameter and a transmit period. The system can further facilitate determining whether the first release parameter matches a second release parameter stored in the memory. The system can further facilitate, in response to the determining indicating that the first release parameter matched the second release parameter, updating a resource map used to transmit data, resulting in an updated resource map. The system can further facilitate transmitting the slot format based on the transmit period.
