METHOD FOR TRANSMITTING PUSCH IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR

원문 (중국어)

A method by which a terminal transmits a physical uplink shared channel (PUSCH) in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving a higher layer message including information related to a PUSCH (multi-TU PUSCH) configuration transmitted from multiple time units (TUs); receiving a lower layer message related to a spatial relation RS to be applied to the transmission of the multi-TU PUSCH; determining a beam for the transmission of the multi-TU PUSCH on the basis of the higher layer message and the lower layer message; and transmitting the multi-TU PUSCH on the basis of the determined beam. The multiple TUs are sorted into multiple TU groups, the lower layer message includes information indicating at least one RS to be applied to each TU group from among the multiple TU groups, and the beam is determined for each TU group.
