Title:
BASE STATION AND USER DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/147060
Kind Code:
A1
Abstract:
Disclosed is a technology for transmitting and receiving a control channel by means of a directional beam. According to an aspect of the present invention, this base station comprises: a scheduling unit for allocating a wireless resource to a user device; and a signal processing unit for processing wireless signals transmitted to and received from the user device, wherein the scheduling unit allocates control information, which is transmitted to the user device, to a wireless resource in a search space specific to the user device, and the signal processing unit transmits the control information to the user device by means of a transmission beam corresponding to the allocated wireless resource among multiple types of transmission beams.
