Abstract
A terminal according to an aspect of the present disclosure includes a receiving section that receives demodulation reference signal (DMRS) information relating to at least one resource of a DMRS, to which at least one DMRS a first precoder for a beam is applied and a second precoder for superposing signals for a plurality of terminals in the beam is not applied, and a control section that demodulates a physical downlink shared channel (PDSCH) to which the first precoder and the second precoder are applied, based on the DMRS and information relating to the second precoder. According to an aspect of the present disclosure, downlink throughput using the MIMO can be improved.
