Abstract: This application provides a communication method and apparatus. The method is applicable to a first terminal device, and the method includes that the first terminal device receives first uplink grant information. The method further includes that the first terminal device determines a resource for uplink transmission based on a first field in the first uplink grant information, and performs uplink transmission based on the resource. The first field is used for frequency domain resource allocation indication, a length Y of the first field is less than X, where X is a pre-specified value, or X is a length of a second frequency domain resource allocation field associated with a second uplink grant format. The first terminal device does not support the second uplink grant format. Y is related to a quantity N of resource blocks supported or configured by the first terminal device.
