Title:
METHOD FOR TRANSMITTING/RECEIVING PDSCH IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/066631
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method for transmitting/receiving a PDSCH in a wireless communication system, and a device therefor. Particularly, a method by which a terminal receives a PDSCH comprises the steps of: receiving configuration information, the configuration information including (i) first information for configuring semi-persistent downlink transmission and (ii) second information related to control resource sets (CORESETs), the first information including a plurality of configurations related to downlink semi-persistent scheduling (SPS), and (i) a first CORESET, which corresponds to a first CORESET group index, and (ii) a second CORESET, which corresponds to a second CORESET group index, being configured on the basis of the second information; receiving first downlink control information (DCI) based on the first CORESET and second DCI based on a second CORESET, the semi-persistent downlink transmission being activated on the basis of the first DCI and/or the second DCI; and receiving a semi-persistent scheduling PDSCH on the basis of the activation, the SPS PDSCH being associated with a CORESET group index corresponding to a CORESET, which has received DCI by which the semi-persistent downlink transmission is activated.
