Apparatus and system

A system comprising a base station and an apparatus, wherein

• the base station comprises:
• a transmitter that transmits downlink control information that is used for scheduling of a downlink shared channel, via a downlink control channel in a control resource set;
• and
• a processor that designates a starting location in a time domain of the downlink shared channel based on the downlink control information,
• wherein when the downlink shared channel overlaps with the control resource set, a resource to which the downlink control information is mapped is not available for the downlink shared channel, and
• wherein a field value in the downlink control information indicates an index for designating one of a plurality of starting locations that are provided in advance, and
• the apparatus comprises:
• a receiver that receives the downlink control information;
• a processor that determines a starting location in a time domain of the downlink shared channel based on the downlink control information;
• and
• an output device that performs output based on downlink data signal in the downlink shared channel.
