An apparatus according to an aspect of the present disclosure includes a communication module that includes a transmitter that carries out an uplink transmission of an uplink shared channel (physical uplink shared channel (PUSCH)), and a processor that controls a transmission power used in the uplink transmission based on: a value that is calculated based on a number of resource blocks of the uplink transmission and one of a plurality of numerologies having different subcarrier spacings, and a transmission power command (TPC) included in a downlink control information (DCI) format, wherein information about the one of the plurality of numerologies is received via higher layer signaling; and an input apparatus that accepts an input, wherein the PUSCH contains information based on the input. In another aspect, a system is also disclosed.
