Base station apparatus, terminal apparatus, and communication method

A base station apparatus comprising:

• a transmission unit configured to transmit an RRC (Radio Resource Control) message including first configuration information and an RRC message including second configuration information and to transmit downlink control information (DCI) on a physical downlink control channel (PDCCH),
• a determination unit configured to determine a bit sequence indicated by a first field of the DCI based on time domain resource allocation for receiving physical uplink shared channel (PUSCH) and a resource allocation table indicating a correspondence between the first bit sequence and the time domain resource allocation, and
• a reception unit configured to receive the PUSCH based on the time domain resource allocation, wherein
• in a case that the transmission unit transmits the DCI with a first DCI format, the first configuration information includes a first parameter list, and the second configuration information does not include a second parameter list, the resource allocation table is defined by the first parameter list,
• in a case that the transmission unit transmits the DCI with a second DCI format and the second configuration information includes the second parameter list, the resource allocation table is defined by the second parameter list, and
• in a case that the transmission unit transmits the DCI with a second DCI format and the second in a case that the transmission unit transmits the DCI with a second DCI format and the second configuration information includes a third parameter list, the resource allocation table is defined by the third parameter list.

A communication method for a terminal apparatus, the communication method comprising:

• receiving an RRC (Radio Resource Control) message including first configuration information and an RRC message including second configuration information and to receive downlink control information (DCI) on a physical downlink control channel (PDCCH),
• determining time domain resource allocation for transmitting physical uplink shared channel (PUSCH) based on a bit sequence indicated by a first field of the DCI and a resource allocation table indicating a correspondence between the bit sequence and the time domain resource allocation, and
• transmitting the PUSCH based on the time domain resource allocation, wherein
• in a case that the terminal apparatus receives the DCI with a first DCI format, the first configuration information includes a first parameter list, and the second configuration information does not include a second parameter list, the resource allocation table is defined by the first parameter list,
• in a case that the terminal apparatus receives the DCI with the first DCI format and the second configuration information includes the second parameter list, the resource allocation table is defined by the second parameter list, and
• in a case that the terminal apparatus receives the DCI with a second DCI format and the second configuration information includes a third parameter list, the resource allocation table is defined by the third parameter list.
