Method and apparatus for time domain resource allocation (TDRA) of physical downlink shared channel (PDSCH) in wireless communication system

A base station (BS) in a wireless communication system, the BS comprising:

• a radio frequency (RF) module configured to transmit and receive a radio signal;
• and
• a processor functionally connected to the RF module,
• wherein the processor is configured to control the RF module to:
• transmit, to a user equipment (UE), downlink control information (DCI) for allocation of a resource for a physical downlink shared channel (PDSCH) in time-domain,
• wherein the DCI includes a field for an entry among entries included in a time-domain resource allocation (TDRA) table,
• wherein a value of the field is related to an index value of the entry based on the field,
• wherein a location of a first symbol of the resource for the PDSCH in the time-domain is relative to (i) a first symbol of a physical downlink control channel (PDCCH) related to the PDSCH, based on that the value of the field is included in a specific value range, and
• wherein the location of the first symbol of the resource for the PDSCH in the time-domain is relative to (ii) a first symbol in a slot related to the PDSCH, based on that the value of the field is included in a range other than the specific value range.
