Abstract: A terminal according to one aspect of the present disclosure includes a receiving section that receives an indication of a transmission configuration indication (TCI) state to be applied to a plurality of types of channels, and at least one of first configuration information related to a control resource set (CORESET) and second configuration information related to a search space, and a control section that judges, based on at least one of the first configuration information and the second configuration information, the TCI state to be applied to a specific CORESET related to terminal-specific and non-terminal-specific reception. The specific CORESET is a CORESET other than a CORESET configured by using a system information block or a master information block. According to one aspect of the present disclosure, it is possible to appropriately recognize a TCI state.

Abstract: A terminal according to one aspect of the present disclosure includes a receiving section that receives downlink control information including a resource assignment of a physical uplink shared channel and a value of an antenna port indication, and a control section that controls transmission of a demodulation reference signal (DMRS), based on an association between the value, the number of code division multiplexing (CDM) groups, and a DMRS port. The number of the CDM groups for DMRS configuration type 1 is larger than 2, and the number of the CDM groups for DMRS configuration type 2 is larger than 3. According to one aspect of the present disclosure, an appropriate number of DMRS ports can be used.

Abstract: A terminal, as disclosed, includes: a processor that, for a plurality of physical downlink shared channels (PDSCHs) transmitted from a plurality of transmission reception points (TRPs), respectively, controls transmission of capability information for indicating a first maximum number regarding a number of layers per PDSCH and a second maximum number regarding a total number of layers of the plurality of PDSCHS; and a receiver that receives the plurality of PDSCHs. The processor controls reporting of a single channel state information (CSI) for the plurality of TRPs, the single CSI indicating a first rank and a second rank that are determined according to a set of ranks based on higher layer signaling. In other aspects, a radio communication method, a base station, and a system are also disclosed.

Abstract: A terminal receives a radio frame having a second slot pattern to be used in a case in which a modulation system (FTN) different from a modulation system in a case of using a first slot pattern is applied. The terminal applies for the second slot pattern a configuration of an uplink and a downlink according to a time division duplex in the radio frame by using a reference subcarrier spacing same as that for the first slot pattern.
