Title:
WIRELESS RELAY DEVICE HAVING INTERFERENCE CANCELLATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2012/091195
Kind Code:
A1
Abstract:
The present invention relates to a wireless relay device, and particularly, to a wireless relay device having an interference cancellation function, wherein efficient data transmission is enabled by cancelling the interference phenomenon between an uplink and a downlink, which occurs in a relay node of an LTE system. According to the present invention, a wireless relay device having an interference cancellation function is a wireless relay device which provides a downlink signal applied from a base station to a terminal and provides an uplink signal applied from the terminal to the base station, wherein the wireless relay device comprises: a highly directional backhaul antenna that has a first beam width for transmitting and receiving a signal with said base station; an access antenna that has a wider second beam width than the first beam width of the highly directional antenna for transmitting and receiving a signal with said terminal; and a relay processing means that relays, to the base station or the terminal, the signals applied from the highly directional backhaul antenna and the access antenna.
