A communication device, a communication method and a communication system that enable an increase in channel capacity at cell edges of a plurality of cells. Data transmission is implemented by transmission stations, which are base stations of adjacent cells, by MIMO transmission. A relay station receives radio waves that are transmitted by both the transmission station and the transmission station, and acquires data transmitted by the transmission station and data transmitted by the transmission station. The relay station transmits data to reception stations in adjacent cells according to multi-user MIMO transmission. The data transmitted by the transmission station is received by the reception station via the relay station, and the data transmitted by the transmission station is received by the reception station via the relay station. The present invention can be used in cellular systems.

摘要:
After checking a status of frequency band usage of a primary system by preliminary sensing, a master node transmits to slave nodes a sensing request containing a target frequency band for cooperative sensing. The slave nodes perform spectrum sensing according to specified parameters and send, as responses, results thereof to the master node. The master node collectively receives these results, comprehensively determines the sensing results of the slave nodes, and makes a final determination on whether or not the target frequency band is available.
摘要:
An ink jet recording apparatus is provided with a black head and a plurality of color heads. The black head has a predetermined number of first orifices aligned at predetermined intervals (e.g. 0.0169 mm) in a sub scanning direction (direction in which a print medium travels). The plurality of color heads eject different colored ink drops. Each color head has the predetermined number of second orifices aligned in the sub scanning direction perpendicular to the main scanning direction. The second orifices of adjacent color heads are aligned in a main scanning direction perpendicular to the sub scanning direction.
