A communication method and a communications device are provided, to improve flexibility of transmitting a physical uplink shared channel resource. In at least some embodiments, first indication information is generated by a network device, where the first indication information is used to indicate one or more frequency hopping bandwidths used by a terminal device to send a physical uplink shared channel resource to the network device. The first indication information is sent by the network device to the terminal device. The methods provided in the embodiments may be applied to a communications system, e.g., vehicle to everything (V2X), vehicle-to-vehicle (V2V), internet of vehicles (IoV), to improve an autonomous driving capability of a vehicle.
