Title:
METHOD FOR TRANSMITTING/RECEIVING NARROWBAND PDCCH IN NARROWBAND-SUPPORTING WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/156521
Kind Code:
A1
Abstract:
The present specification discloses a method for a terminal receiving a narrowband PDCCH in a narrowband-supporting wireless communication system, and a device therefor. Specifically, the method comprises the steps of: receiving search space-related information from a base station via upper layer signaling; and receiving, from the base station, a narrowband PDCCH from the search space, which comprises one or more narrowband PDCCH candidates, wherein the search space includes a first search space defined on the basis of the search space-related information, and a second search space having the same type as that of the first search space, wherein, when one portion of the first search space and the second search space overlap, at least one NPDCCH candidate, in the first search space, overlapping with the second search space is dropped.
