Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). An embodiment of the present disclosure provides a base station, a user equipment (UE), and a method for uplink resource allocation and a method for uplink transmission, which are applied in the field of communication technologies. The method includes that: a base station allocates Bandwidth Part (BWP) resources and intra-BWP Physical Resource Block (PRB) resources to a UE, and then transmits BWP resource indication information and intra-BWP PRB resource indication information to the UE. The BWP resource indication information is used for indicating the BWP resources allocated by the base station to the UE. The intra-BWP PRB resource indication information is used for indicating the intra-BWP PRB resources allocated by the base station, and then the UE receives the BWP resource indication information and the intra-BWP PRB resource indication information transmitted by the base station, and then determines the BWP resources and the intra-BWP PRB resources allocated by the base station according to the BWP resource indication information and the intra-BWP PRB resource indication information so as to perform uplink transmission.
