According to an embodiment, a user equipment (UE) receives downlink control information (DCI) through a physical downlink control channel (PDCCH), determines a downlink resource allocated to the UE based on a frequency domain resource allocation (FDRA) field included in the DCI, and receives a physical downlink shared channel (PDSCH) in the downlink resource, and in this case, based on that a first bandwidth of the UE supported for the PDCCH is different from a second bandwidth of the UE supported for the PDSCH, the UE determines the downlink resource allocated through the FDRA field based on the second bandwidth other than the first bandwidth.
