Embodiments of this application relate to a resource configuration method, a terminal device, and a network device. The method includes: determining a frequency domain offset between a plurality of transmission resource chunks allocated by a network device, where the frequency domain offset is a frequency domain offset between a first transmission resource chunk and a second transmission resource chunk, and the first transmission resource chunk and the second transmission resource chunk are any two consecutive resource chunks on an uplink transmission in the plurality of transmission resource chunks; and determining the plurality of transmission resource chunks according to the frequency domain offset, wherein the plurality of transmission resource chunks are configured for a frequency hopping transmission.
