1. A terminal comprising:
a transceiver that receives, from a base station apparatus, configuration information designating a Bandwidth Part (BWP) configured for a cell and a system information block 1 (SIB1); and
a processor that designates, based on a parameter included in the configuration information,
a BWP to be activated when the cell is a Special Cell (SpCell) and a configuration is executed with a Radio Resource Control (RRC), or
a BWP to be activated when the cell is a Secondary Cell (SCell) and a Media Access Control (MAC) layer is activated,
wherein the transceiver communicates with the base station apparatus by using the BWP,
wherein the parameter includes a field that is mandatorily present when the cell is the SpCell or the SCell,
wherein the parameter is configured in the configuration information in a case where only an initial BWP is configured for the cell,
wherein the parameter includes a first identity of an uplink BWP and a second identity of a downlink BWP, and the first identity and the second identity have a same value, and
wherein the processor configures the initial BWP based on an information element in the SIB1.
