Title:
MEHOD FOR TRANSMITTING AND RECEIVING PHYSICAL DOWNLINK SHARED CHANNEL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/029749
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method for transmitting and receiving a physical downlink shared channel (PDSCH) in a wireless communication system, and a device therefor. Particularly, a method by which user equipment (UE) receives a PDSCH in a wireless communication system comprises the steps of: receiving configuration information for the PDSCH, the configuration information including a plurality of TCI state configurations; receiving activation information, the plurality of TCI state configurations being activated by the activation information, and the activation information including mapping information about the activated TCI state configurations and code points of a transmission configuration indication (TCI) field in downlink control information; receiving the DCI including the TCI field; and receiving a plurality of PDSCH transmission occasions on the basis of the indication, through the TCI field, of a specific code point mapped to a plurality of TCI states, wherein the plurality of PDSCH transmission occasions correspond to the same transport block, the plurality of PDSCH transmission occasions are received in a time area resource on the basis of time division multiplexing (TDM), and the number of the plurality of PDSCH transmission occasions can be determined on the basis of the number of TCI states mapped to the specific code point.
