METHOD FOR TRANSMITTING AND RECEIVING DATA REPEATEDLY TRANSMITTED IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE FOR SAME

WIPO Patent Application WO/2021/029747

A1

Disclosed are a method for transmitting and receiving downlink data in a wireless communication system, and a device for same. Specifically, a method for a user equipment (UE) to receive downlink data in a wireless communication system includes the steps of: receiving setting information for power measurement related to beam reporting; receiving a reference signal for the power measurement on the basis of the setting information; performing the power measurement on the basis of the reference signal; receiving downlink control information (DCI) through a reception beam determined on the basis of the power measurement; and receiving a plurality of transmission occasions on the basis of the DCI, wherein the DCI may include a transmission configuration indication (TCI) field, a plurality of TCI states may be indicated on the basis of the TCI field, the plurality of transmission occasions may correspond to the same transport block, the plurality of transmission occasions may be received in different time domain resources on the basis of time division multiplexing (TDM), and the number of the plurality of transmission occasions may be determined on the basis of the number of the plurality of TCI states.
