Title:
BASE STATION DEVICE AND TRANSMITTING METHOD
Document Type and Number:
WIPO Patent Application WO/2012/108155
Kind Code:
A1
Abstract:
The present invention provides a base station device capable of improving the throughput of a whole network by minimizing interference between respective base stations (MeNB and HeNB).
In a communication system including a plurality of base stations, which transmit a signal by using any of a plurality of different ABS (Almost Blank Subframe) patterns which are sub frame ABS patterns represented by the combination of a transmission sub frame for transmitting a signal and a non-transmission sub frame for suspending the transmission of the signal, a determining unit (104), on the basis of the presence or absence of the interference between an HeNB (100) and other base stations except for the HeNB (100), determines the ABS pattern used by the HeNB (100) from among the plurality of ABS patterns, and a transmitting unit (105) transmits a signal to a terminal connected to the HeNB (100) in accordance with the determined ABS pattern.
