1. A method of transmitting and receiving, by a user equipment (UE), a physical channel in a wireless communication system, the method comprising:
receiving configuration information;
receiving control information including a plurality of L pieces of beam information (spatial relation information, Transmission Configuration Indication (TCI) state); and
performing transmission of an uplink channel or reception of a downlink channel based on the control information,
wherein a repetitive transmission scheme combining two or more of i) Spatial Division Multiplexing (SDM), ii) Frequency Division Multiplexing (FDM) or iii) Time Division Multiplexing (TDM) is configured based on the configuration information,
a plurality of m transmission occasions are configured based on the repetitive transmission scheme,
each of the transmission occasions is indexed based on a positive integer i including 0,
the plurality of pieces of beam information respectively relate to the transmission occasions based on the order of the plurality of transmission occasions based on a predefined rule, and
based on the number L of beam information being smaller than the number m of plurality of transmission occasions (TOs), the rule is predefined so that the beam information relating to (i) an index of beam information mapped to TO (i−L) and (ii) an index determined based on a specific offset value is mapped to the TO i with i>=L.
