Abstract

Claims (26)

1. A terminal apparatus, comprising:

a reception unit configured to:

when a carrier is set in an unlicensed band, detect a first Physical Downlink Control Channel (PDCCH) in a first type 0 PDCCH common search space set and receive a first Physical Downlink Shared Channel (PDSCH) scheduled by the first PDCCH, and

when the carrier is not set in the unlicensed band, detect a second PDCCH in a second type 0 PDCCH common search space set and receive a second PDSCH scheduled by the second PDCCH; and

a higher layer processing unit configured to manage common Radio Resource Control (RRC) signaling included in the first PDSCH or the second PDSCH, wherein:

a time domain resource configuration of the first PDSCH is a first configuration, and

a time domain resource configuration of the second PDSCH is a second configuration different from the first configuration.

2. A base station apparatus, comprising:

a transmission unit configured to:

when a carrier is set in an unlicensed band, transmit a first Physical Downlink Control Channel (PDCCH) in a first type 0 PDCCH common search space set and transmit a first Physical Downlink Shared Channel (PDSCH) scheduled by the first PDCCH, and

when the carrier is not set in the unlicensed band, transmit a second PDCCH in a second type 0 PDCCH common search space set and transmit a second PDSCH scheduled by the second PDCCH; and

a higher layer processing unit configured to manage common Radio Resource Control (RRC) signaling included in the first PDSCH or the second PDSCH, wherein:

a time domain resource configuration of the first PDSCH is a first configuration, and

a time domain resource configuration of the second PDSCH is a second configuration different from the first configuration.

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

when a carrier is set in an unlicensed band, detecting a first Physical Downlink Control Channel (PDCCH) in a first type 0 PDCCH common search space set and receiving a first Physical Downlink Shared Channel (PDSCH) scheduled by the first PDCCH;

when the carrier is not set in the unlicensed band, detecting a second PDCCH in a second type 0 PDCCH common search space set and receiving a second PDSCH scheduled by the second PDCCH; and

managing common Radio Resource Control (RRC) signaling included in the first PDSCH or the second PDSCH, wherein:

a time domain resource configuration of the first PDSCH is a first configuration, and

a time domain resource configuration of the second PDSCH is a second configuration different from the first configuration.

4. A communication method for a base station apparatus, the communication method comprising:

when a carrier is set in an unlicensed band, transmitting a first Physical Downlink Control Channel (PDCCH) in a first type 0 PDCCH common search space set and transmitting a first Physical Downlink Shared Channel (PDSCH) scheduled by the first PDCCH;

when the carrier is not set in the unlicensed band, transmitting a second PDCCH in a second type 0 PDCCH common search space set and transmitting a second PDSCH scheduled by the second PDCCH; and

managing common Radio Resource Control (RRC) signaling included in the first PDSCH or the second PDSCH, wherein:

a time domain resource configuration of the first PDSCH is a first configuration, and

a time domain resource configuration of the second PDSCH is a second configuration different from the first configuration.
