Abstract

The invention relates to a wireless base station device for communication with a wireless terminal, a wireless portion control device and a wireless communication method. According to the invention, the communication quality of terminals around communities is improved. The wireless base station device comprises a plurality of wireless portions (R11, R12) which is equipped with a plurality of antennas; a reception power measuring portion (104) for measuring the reception power of uplink signals of a wireless terminal device (MS11) for each antenna; an antenna information manufacturing portion (109) for manufacturing information for expression of antenna combination, according to each adjacent antenna portion and based on information expressing adjacent relations among the wireless portions and the antenna direction of the wireless portions; and an antenna selection portion (111) for selecting an antenna cpmbination alternative used in macro-diversity communication with a wireless terminal based on the measured value of reception power, and for determining the antenna combination used in macro-diversity communication based on the antenna cpmbination alternative and the information expressing the antenna combination.
