Title:
METHOD FOR RECEIVING DOWNLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM SUPPORTING UNLICENSED BAND, AND DEVICE FOR SUPPORTING SAME
Document Type and Number:
WIPO Patent Application WO/2017/171422
Kind Code:
A1
Abstract:
Disclosed in the present invention are: a method for transmitting and receiving a downlink signal between a terminal and a base station in a Licensed Assisted Access (LAA) system in which the base station or the terminal transmits a Listen-Before-Talk (LBT) based signal; and a device for supporting the same. Specifically, disclosed in the present invention are: a method for allowing a terminal to novelly define a search space to be monitored, in order to receive the downlink control channel corresponding to a specific aggregation level and, on the basis of this, transmitting and receiving the downlink signal between the terminal and the base station; and a device supporting the same.
