Title:
APPARATUS AND METHOD FOR CANCELING SHADOW AREA IN NEXT-GENERATION WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/174433
Kind Code:
A1
Abstract:
Disclosed is an apparatus for canceling a shadow area of a next-generation wireless communication system, comprising: an antenna & donor (AU) device including an ultrahigh frequency communication unit for allowing the transmission/reception (communication) of an ultrahigh frequency wireless signal with an ultrahigh frequency base station, and a first signal conversion unit for converting the ultrahigh frequency wireless signal, which has been received from the ultrahigh frequency base station through the ultrahigh frequency communication unit, into an optical signal and performing (downlink) transmission on the same through one or more optical lines, and converting an optical signal, which has been received through the one or more optical lines, into an ultrahigh frequency wireless signal and performing transmission (uplink) on the same to the ultrahigh frequency base station through the ultrahigh frequency communication unit; and one or more access point (AP) devices including a WiFi communication unit for communicating with a user terminal through a WiFi signal, and a second signal conversion unit for converting a WiFi signal, which has been received from the user terminal through the WiFi communication unit, into an optical signal and performing transmission (uplink) on the same through one of the one or more optical lines, and converting an optical signal, which has been received through one of the one or more optical lines, into a WiFi signal and performing transmission (downlink) on the same to the user terminal through the WiFi communication unit.
