Terminal apparatus, base station apparatus, and communication method

A base station apparatus comprising:

• a transmitter configured to transmit a PDCCH to which DCI is mapped or to transmit a PDSCH including a random access response grant;
• and
• a receiver configured to receive a PUSCH, wherein
• frequency hopping for the PUSCH is performed based at least on the DCI or the random access response grant,
• in a case that the PUSCH is scheduled by the DCI with a CRC scrambled by a TC-RNTI, a frequency hopping interval corresponding to the frequency hopping is one slot,
• in a case that the PUSCH is scheduled by the random access response grant, the frequency hopping interval is one slot, and
• in a case that the PUSCH is scheduled by the DCI with a CRC scrambled by at least one of a C-RNTI, a CS-RNTI, or an MCS-C-RNTI, the number of slots for the frequency hopping interval is determined by a certain higher layer parameter.

A communication method used in a terminal apparatus, the communication method comprising the steps of:

• receiving a PDCCH to which DCI is mapped or receiving a PDSCH including a random access response grant;
• and
• transmitting a PUSCH, wherein
• frequency hopping for the PUSCH is performed based at least on the DCI or the random access response grant,
• in a case that the PUSCH is scheduled by the DCI with a CRC scrambled by a TC-RNTI, a frequency hopping interval corresponding to the frequency hopping is one slot,
• in a case that the PUSCH is scheduled by the random access response grant, the frequency hopping interval is one slot, and
• in a case that the PUSCH is scheduled by the DCI with a CRC scrambled by at least one of a C-RNTI, a CS-RNTI, or an MCS-C-RNTI, the number of slots for the frequency hopping interval is determined by a certain higher layer parameter.
