Claim 8:
9. A communication method for a terminal apparatus, the communication method comprising:
receiving a setting of an initial downlink (DL) bandwidth part (BWP) via a radio resource control (RRC) message;
receiving a downlink control information (DCI) format that schedules a physical downlink shared channel (PDSCH) in an active DL BWP; and
identifying, in a field in the DCI format, a value corresponding to a resource block set to which the PDSCH is allocated and which is indicated by a start resource block and a number of consecutively allocated resource blocks, wherein
the setting of the initial DL BWP comprises setting a first parameter and a second parameter of a control resource set (CORESET) #0,
a value of an identifier of the CORESET #0 is 0,
the first parameter represents a size of the CORESET #0,
the second parameter represents a size of the initial DL BWP,
a serving cell is set with the initial DL BWP and an additional DL BWP,
one of the initial DL BWP and the additional DL BWP is activated as the active DL BWP,
the identified value is determined based on a size of a DL BWP, the start resource block, and the number of the consecutively allocated resource blocks,
a size of the DCI format in a common search space (CSS) is determined based on the size of the CORESET #0, and when the field in the DCI format is applied to the active DL BWP, the size of the DL BWP is the size of the CORESET #0, and
a size of the DCI format in a user equipment (UE)-specific search space (USS) is determined based on a size of the active DL BWP, and when the field in the DCI format is applied to the active DL BWP, the size of the DL BWP is the size of the active DL BWP.
