Configuration method for sidelink configured grant, device and storage medium
View Patent ↗Embodiments of the present application provide a configuration method for a sidelink configured grant, a device and a storage medium. The method includes: sending, by a network device, a parameter for determining sidelink configured grant (CG) transmission resources, where the CG transmission resources have same time domain positions in different frame periods. Since the CG transmission resources determined using the parameter configured via a network have the same time domain positions in different frame periods, a terminal device may accurately determine the time domain position of the CG transmission resource no matter in which frame period the terminal device has received the parameter sent by the network device.
