Terminal apparatus, base station apparatus, and communication method

A base station apparatus comprising:

• higher layer processing circuitry configured to generate System Information Block 1 (SIB1);
• and
• a transmitter configured to transmit the SIB1, and to transmit physical downlink control channel based on first information included in the SIB1,
• wherein, the SIB1 includes second information indicating a first frequency location and first bandwidth of initial downlink band width part (BWP),
• in a case that the SIB1 includes third information indicating a second frequency location and second bandwidth of the initial downlink BWP, a frequency location and bandwidth of the initial downlink BWP is indicated by the third information,
• in a case that the SIB1 does not include the third information, the frequency location and the bandwidth of the initial downlink BWP is indicated by the second information, and
• the transmitter is configured to transmit the physical downlink control channel based on the first information, regardless of whether the SIB1 includes the third information.

A communication method for a terminal apparatus comprising:

• receiving System Information Block 1 (SIB1);
• and
• monitoring physical downlink control channel based on first information included in the SIB1,
• wherein, the SIB1 includes second information indicating a first frequency location and first bandwidth of initial downlink band width part (BWP),
• in a case that the SIB1 includes third information indicating a second frequency location and second bandwidth of the initial downlink BWP, a frequency location and bandwidth of the initial downlink BWP is indicated by the third information,
• in a case that the SIB1 does not include the third information, the frequency location and the bandwidth of the initial downlink BWP is indicated by the second information, and
• the monitoring the physical downlink control channel is based on the first information, regardless of whether the SIB1 includes the third information.
