    Abstract: A communication method includes determining, by a network device according a value of a resource bundling granularity, at least one precoding resource block group in a scheduling resource corresponding to the terminal device, where a type of the value of the resource bundling granularity is one of a first-type value and a second-type value, and a precoding resource block group determining method corresponding to the first-type value and the second-type value are different. The method further includes transmitting, by the network device, data to the terminal device by using the at least one precoding resource block group. Based on different values of the resource bundling granularity, different methods are used to determine the at least one precoding resource block group in the scheduling resource.
