Terminal and radio communication method
A terminal includes a receiving section that receives downlink control information for which cyclic redundancy check (CRC) bits are scrambled with use of a radio network temporary identifier (RNTI) common to one or more terminals, and a control section that controls reception of data associated with a multicast traffic channel (MTCH) with use of a physical downlink shared channel scheduled by the downlink control information in one or more bandwidth parts in a cell. Therefore, it is possible to appropriately control reception of multicast transmission using a physical downlink shared channel.
1. A terminal comprising:
a receiver that receives downlink control information for which cyclic redundancy check (CRC) bits are scrambled in a radio network temporary identifier (RNTI) common to one or more terminals; and
a processor that controls the receiver to receive data associated with a multicast traffic channel (MTCH) in a first physical downlink shared channel (PDSCH) scheduled by the downlink control information in one or more bandwidth parts in a cell,
wherein when the terminal is in each of an idle state and a connected state, the receiver receives first information for reception of the data by using a second PDSCH associated with a multicast control channel (MCCH), the first information for reception of the data including a configuration related to the first PDSCH for the MTCH, and
wherein when the terminal is in an inactive state, the receiver receives, by using system information, second information for reception of the data, the second information for reception of the data including information indicating CORESET for PDCCH scheduling the first PDSCH for the MTCH.
2. The terminal according to claim 1 , wherein quasi-co-location (QCL) relationship used for reception of the second PDSCH associated with the MCCH is determined based on information transferred by system information.
3. A radio communication method for a terminal, the radio communication method comprising:
receiving downlink control information for which cyclic redundancy check (CRC) bits are scrambled in a radio network temporary identifier (RNTI) common to one or more terminals;
receiving data associated with a multicast traffic channel (MTCH) in a first physical downlink shared channel (PDSCH) scheduled by the downlink control information in one or more bandwidth parts in a cell;
receiving first information for reception of the data by using a second PDSCH associated with a multicast control channel (MCCH) when the terminal is in each of an idle state, and a connected state, the first information for reception of the data including a configuration related to the first PDSCH for the MTCH; and
receiving, by using system information, second information for reception of the data when the terminal is in an inactive state, the second information for reception of the data including information indicating a CORESET for PDCCH scheduling the first PDSCH for the MTCH.
4. A base station comprising:
a transmitter that transmits downlink control information for which cyclic redundancy check (CRC) bits are scrambled in a radio network temporary identifier (RNTI) common to one or more terminals; and
a processor that controls the transmitter to transmit data associated with a multicast traffic channel (MTCH) in a first physical downlink shared channel (PDSCH) scheduled by the downlink control information in one or more bandwidth parts in a cell,
wherein when the terminal is in each of an idle state and a connected state, the transmitter transmits first information for reception of the data by using a second PDSCH associated with a multicast control channel (MCCH), the first information for reception of the data including a configuration related to the first PDSCH for the MTCH, and
wherein when the terminal is in an inactive state, the transmitter transmits, by using system information, second information for reception of the data, the second information for reception of the data including information indicating CORESET for PDCCH scheduling the first PDSCH for the MTCH.
5. A system comprising a terminal and a base station, wherein:
the terminal comprises:
a receiver that receives downlink control information for which cyclic redundancy check (CRC) bits are scrambled in a radio network temporary identifier (RNTI) common to one or more terminals; and
a processor that controls the receiver to receive data associated with a multicast traffic channel (MTCH) in a first physical downlink shared channel (PDSCH) scheduled by the downlink control information in one or more bandwidth parts in a cell,
wherein when the terminal is in each of an idle state and a connected state, the receiver receives first information for reception of the data by using a second PDSCH associated with a multicast control channel (MCCH), the first information for reception of the data including a configuration related to the first PDSCH for the MTCH, and
wherein when the terminal is in an inactive state, the receiver receives, by using system information, second information for reception of the data, the second information for reception of the data including information indicating CORESET for PDCCH scheduling the first PDSCH for the MTCH, and
the base station comprises:
a transmitter that transmits the downlink control information.
