    Abstract: An apparatus is disclosed that includes a receiver that receives downlink control information that is used for scheduling of a downlink shared channel, via a downlink control channel in a control resource set. The apparatus also includes a processor that determines a starting location in a time domain of the downlink shared channel based on the downlink control information. The apparatus further includes an output device that performs output based on downlink data signal in the downlink shared channel. 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. In another aspect, a system is also disclosed.
