Terminal apparatus, base station apparatus, and communication method

A base station apparatus comprising:

• transmitting circuitry configured to transmit a Physical Downlink Control Channel (PDCCH) including a Downlink Control Information (DCI) format for determining a first spatial filter and a second spatial filter;
• and
• receiving circuitry configured to receive a Physical Uplink Shared Channel (PUSCH) scheduled by the DCI format in a slot set, wherein:
• the first spatial filter is applied to the PUSCH in a first slot subset of the slot set, and the second spatial filter is applied to the PUSCH in a second slot subset of the slot set,
• a number of slots of the first slot subset in a first part of one period during which the first spatial filter is continuously mapped, and a number of slots of the second slot subset in a second part of the one period during which the second spatial filter is continuously mapped, are determined based on a Radio Resource Control (RRC) parameter, and
• the first slot subset comprises the same number of slots as the second slot subset, and the number of slots in the first slot subset remains the same in each one period.

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

• receiving a Physical Downlink Control Channel (PDCCH) including a Downlink Control Information (DCI) format for determining a first spatial filter and a second spatial filter;
• transmitting a Physical Uplink Shared Channel (PUSCH) scheduled by the DCI format in a slot set;
• and
• applying the first spatial filter to the PUSCH in a first slot subset of the slot set, and applying the second spatial filter to the PUSCH in a second slot subset of the slot set, wherein;
• a number of slots of the first slot subset in a first part of one period, during which the first spatial filter is continuously mapped, and a number of slots of the second slot subset in a second part of the one period, during which the second spatial filter is continuously mapped, are determined based on a Radio Resource Control (RRC) parameter, and
• the first slot subset comprises the same number of slots as the second slot subset, and the number of slots in the first slot subset remains the same in each one period.
