Title:
METHOD AND APPARATUS FOR PERFORMING DOWNLINK TRANSMISSION AND RECEPTION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/080660
Kind Code:
A1
Abstract:
A method and apparatus for performing downlink transmission and reception in a wireless communication system are disclosed. The method by which a terminal performs downlink reception in a wireless communication system, according to an embodiment of the present disclosure, may comprise the steps of: receiving, from a base station, configuration information regarding a plurality of control resource sets (CORESETs); and receiving, on the basis of the plurality of CORESETs, a physical downlink control channel (PDCCH) from the basis station. Here, the plurality of CORESETs may include a first CORESET associated with a plurality of TCI states and a second CORESET associated with a single TCI state. On the basis that a first search space set configured in the first CORESET is linked to a second search space set configured in the second CORESET, a specific TCI state from among the plurality of TCI states associated with the first CORESET, and the single TCI state associated with the second CORESET may be applied to repetitive transmission of the PDCCH.
