Title:
METHOD AND DEVICE FOR TRANSMITTING OR RECEIVING SIGNAL ON BASIS OF SPACE PARAMETER IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/177782
Kind Code:
A1
Abstract:
Disclosed are a method and a device for transmitting or receiving a signal on the basis of a space parameter in a wireless communication system. A method for performing downlink reception or uplink transmission by a terminal in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: transmitting information related to a beam switching time of the terminal to a base station; receiving, from the base station, downlink control information (DCI) including information on the downlink reception or the uplink transmission; and on the basis of the beam switching time and a predetermined threshold value, applying one space parameter set among multiple space parameter sets so as to perform the downlink reception or the uplink transmission, wherein at least one of the beam switching time and the predetermined threshold value may be based on at least one of subcarrier spacing, the position of a frequency, a capability of the terminal, and a cyclic prefix (CP)-related configuration.
