11. A user equipment which performs a data communication method, the user equipment comprising:
a transceiver; and
a processor coupled to the transceiver and configured to:
receive a higher layer signal indicating a change of a reference point of a start symbol to which a physical downlink shared channel (PDSCH) is assigned;
detect a format of downlink control information (DCI) including PDSCH scheduling information from a physical downlink control channel (PDCCH), the DCI including a cyclic redundancy check (CRC) scrambled to one of a cell radio network temporary identifier (C-RNTI), a modulation and coding scheme cell RNTI (MCS-RNTI), or a configured scheduling RNTI (CS-RNTI); and
determine the start symbol to which the PDSCH is assigned, based on information about the format of the DCI, mapping type information of the PDSCH, and an offset value between a slot in which the PDCCH is located and a slot in which the PDSCH is located.
