Abstract
One aspect of a user terminal according to the present invention includes: a receiving section that receives a downlink shared channel transmitted from a plurality of transmission/reception points; and a control section that controls transmission of a transmission confirmation signal corresponding to the downlink shared channel, based on downlink control information including at least one of a count value and a total value of DL assignment jointly controlled in the plurality of transmission/reception points.

A terminal comprising:
- a receiver that receives downlink control information (DCI) transmitted from each of a plurality of transmit/receive points (TRPs) in a same serving cell and receives a physical downlink shared channel (PDSCH) scheduled by the DCI;
- and
- a processor that controls, based on a counter downlink assignment indicator (DAI) and a total DAI, the counter DAI and the total DAI being jointly counted between the plurality of TRPs and included in the DCI, generation of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook corresponding to the PDSCH.
A radio communication method for a terminal, comprising:
- receiving downlink control information (DCI) transmitted from each of a plurality of transmit/receive points (TRPs) in a same serving cell;
- receiving a physical downlink shared channel (PDSCH) scheduled by the DCI;
- and
- controlling, based on a counter downlink assignment indicator (DAI) and a total DAI, the counter DAI and the total DAI being jointly counted between the plurality of TRPs and included in the DCI, generation of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook corresponding to the PDSCH.
A system comprising a terminal and a base station, wherein
- the terminal comprises:
- a receiver that receives downlink control information (DCI) transmitted from each of a plurality of transmit/receive points (TRPs) in a same serving cell and receives a physical downlink shared channel (PDSCH) scheduled by the DCI;
- and
- a processor of the terminal that controls, based on a counter downlink assignment indicator (DAI) and a total DAI, the counter DAI and the total DAI being jointly counted between the plurality of TRPs and included in the DCI, generation of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook corresponding to the PDSCH, and
- the base station comprises:
- a transmitter that transmits the DCI and the PDSCH from at least one of the plurality of TRPs in the same serving cell;
- and
- a processor of the base station that controls to jointly count the counter DAI and the total DAI, included in the DCI, between the plurality of TRPs.
