Original Abstract Submitted
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.
