1. A method of performing, by a user equipment, an uplink transmission in a wireless communication system, the method comprising:
receiving radio resource control (RRC) signaling including uplink-downlink (UL-DL) configuration information;
determining each symbol as a downlink, uplink or flexible symbol based on the UL-DL configuration information;
receiving downlink control information (DCI) that includes physical uplink shared channel (PUSCH) resource allocation information regarding a plurality of symbols for the uplink transmission;
determining invalid symbols for the uplink transmission among the plurality of symbols, based on the UL-DL configuration information;
determining remaining symbols except the invalid symbols as a plurality of valid symbols for the uplink transmission among the plurality of symbols; and
performing the uplink transmission in each of symbol sets among multiple symbol sets,
wherein determining the invalid symbols for the uplink transmission among the plurality of symbols, based on the UL-DL configuration information, comprises:
determining a symbol that is indicated as downlink by the UL-DL configuration information as an invalid symbol for the uplink transmission,
wherein each of the multiple symbol sets consists of one or more contiguous valid symbols within the plurality of valid symbols, and
wherein performing the uplink transmission comprises:
omitting the uplink transmission in a symbol set among the multiple symbol sets, based on the symbol set including a single symbol.
