Abstract
The present technology improves an effective rate in a case where joint transmission is performed once in multi-APs that perform joint transmission, and then a weight is changed and joint transmission is performed again. A wireless base station includes a wireless control unit and a communication unit. The wireless control unit generates weight update information for updating a first weight to a second weight, the first weight being a weight used in joint transmission previously performed with another wireless base station, the second weight being a weight used for performing the joint transmission after the joint transmission using the first weight. The communication unit notifies the another wireless base station of the weight update information.
