The present disclosure provides a frequency hopping configuration method and device. The method is applied to a base station, and the base station configures at least one bandwidth part BWP for a terminal. The method comprises: configuring a frequency hopping rule for each configured BWP; when the terminal is instructed to perform uplink transmission hopping, determining, according to the configured hopping rule, a hopping rule corresponding to a BWP currently being used by the terminal; and sending the corresponding hopping rule to the terminal, such that the terminal determines a second frequency domain resource position after frequency hopping has been performed according to the corresponding frequency hopping rule and a first frequency domain resource position prior to performing frequency hopping, and performs uplink transmission at the second frequency domain resource position. Therefore, the present disclosure enables a terminal to complete uplink transmission frequency hopping according to a frequency hopping rule indicated by a base station, thereby reducing the complexity of uplink scheduling, while also reducing the fragmentation of system resources and improving the efficiency of system resource utilization.
