METHOD AND DEVICE FOR TRANSMITTING OR RECEIVING DOWNLINK CHANNEL FROM MULTIPLE TRANSMISSION RECEPTION POINTS IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2021/162334

A1

Disclosed are a method and a device for transmitting or receiving a downlink channel from multiple transmission reception points (TRPs) in a wireless communication system. A method for receiving a downlink signal by a terminal in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: repetitively receiving downlink control channels including identical downlink control information (DCI) from one or more TRPs at one or more transmission opportunities (TOs); and receiving a downlink signal from a single TRP on the basis of the fact that the DCI includes control information associated with reception of the downlink signal, the fact that a time interval between a particular TO among the one or more TOs and reception of the downlink signal associated with the DCI has a value smaller than a predetermined threshold, and a default transmission configuration indicator (TCI) state, wherein the default TCI state corresponds to a TCI state associated with a control resource set (CORESET) or a search space set having the lowest identifier in the latest slot monitored by the terminal.
