Abstract
(EN)
According to an embodiment of the present invention, a method for transmitting a physical uplink shared channel (PUSCH) by a terminal in a wireless communication system comprises the steps of: receiving a higher layer message including information related to a configuration of a PUSCH (multi-TU PUSCH) transmitted in a plurality of time units (TUs), wherein the plurality of time units (TUs) are classified into a plurality of TU groups; receiving a lower layer message related to a spatial relation (RS) applied to transmission of the multi-TU PUSCH; on the basis of the lower layer message, determining beams for each of TU groups remaining after excluding at least one specific TU group from among the plurality of TU groups; determining a beam for the at least one specific TU group on the basis of the beams for each of the remaining TU groups; and transmitting the multi-TU PUSCH on the basis of the determined beams.
