Title:
METHOD FOR MONITORING PHYSICAL DOWNLINK CONTROL CHANNEL, AND DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/029724
Kind Code:
A1
Abstract:
Provided are a method and device for monitoring a PDCCH of a terminal in a wireless communication system. The terminal receives first setting information that provides notification of a monitoring occasion for detecting a wake up signal (WUS), and performs monitoring for detecting the wake up signal in the monitoring occasion. If the wake up signal is not detected in the monitoring occasion, whether to monitor a PDCCH in the next DRX-on period is determined on the basis of second setting information that indicates the operation to be applied to the terminal when the terminal does not detect the wake up signal.
