Provided are an apparatus and method for transmitting and receiving an uplink (UL) channel. A method for a user equipment (UE) to transmit a UL control channel and a UL data channel to a base station (BS) includes receiving bandwidth part (BWP) configuration information of a BWP set composed of one or more BWPs configured for a UE from a BS, receiving frequency hopping configuration information for a UL control channel and a UL data channel transmitted through one BWP of the BWP set from the BS, and transmitting a UL control channel and a UL data channel to the BS through the single BWP of the BWP set based on the BWP configuration information and the frequency hopping configuration information.
