Abstract: A communication apparatus and a communication method are provided by which an upper network including a plurality of network groups is formed. A base station transmits a first frame requesting communication for estimating a structure of an upper network to another base station and returns a reply of a second frame to a first frame from the other base station. Then, the base station estimates a structure of the upper network and decides a structure attribute of the base station itself in the upper network on the basis of information acquired through the communications. Then, the base station notifies the other base station or a subordinate terminal of a result of the decision of the structure attribute.

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.
