Title:
METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/261877
Kind Code:
A1
Abstract:
Disclosed are a method and device for transmitting and receiving a signal in a wireless communication system. A method for receiving a downlink signal according to an embodiment of the present disclosure may comprise the steps of: receiving configuration information about the state of a transmission configuration indicator (TCI) of a downlink signal from a base station, wherein the TCI state information includes quasi co-location (QCL) information for configuring a QCL relationship between the downlink signal and a reference signal; and receiving the downlink signal from the base station on the basis of the TCI state information. The reference signal for the downlink signal may be set on the basis of measurement object information for a radio resource management (RRM) measurement configured by the QCL information, a non-serving cell rather than a serving cell of a terminal, and a non-serving cell signal.
