1. A terminal, comprising:
reception circuitry, which, in operation, receives information on an indication of a portion of a plurality of candidate unit time resources for aperiodic transmission of a reference signal; and
control circuitry, which, in operation, controls, based on the information, allocation of a time resource used for the aperiodic transmission of the reference signal, wherein
the control circuitry;
determines an antenna port used for transmitting the reference signal in each of the portion of the plurality of candidate unit time resources, based on an association between each of the plurality of candidate unit time resources and the antenna port; and
does not change the association in a case where the reference signal is dropped in at least one candidate unit time resource among the plurality of candidate unit time resources.
