Abstract

Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a relay node may determine a first predicted motion of a first vehicle including a first wireless communication device having a first established communication channel with the relay node. The relay node may determine that the first predicted motion will trigger a communication condition for the first vehicle and a second wireless communication device having a second established communication channel with the relay node. The relay node may reserve radio resources for a third communication channel between the first wireless communication device and the second wireless communication device.
