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: A communication device and a communication method that transmit and receive wireless packets are provided.
A communication device includes a control unit that determines a subcarrier to be a null tone according to information applied to a packet and a transmission unit that generates a multi-carrier signal in which the determined subcarrier is set as a null tone and wirelessly transmits the signal. The control unit determines a position of a subcarrier and the number of subcarriers to be a null tone or a position of a subcarrier in correspondence with the information and, in addition, changes a subcarrier to be a null tone according to temporal variation of the information.-

Abstract: The present disclosure relates to a transmission apparatus and a transmission method, a reception apparatus and a reception method, and a communication system that make it possible to implement stabilized communication irrespective of a fluctuation of a communication environment in a WLAN (Wireless LAN, WaveLAN).
When a transmission apparatus transmits a data signal to a reception apparatus, the reception apparatus returns a response signal including a feedback parameter (FP) to the transmission apparatus. In a case where a reception situation of the reception apparatus is poor and improvement of it is necessitated on the basis of the FP, the transmission apparatus adjusts transmission power or the like to improve the reception situation of the reception apparatus. The present disclosure can be applied to a communication system in a WLAN.-

Abstract: A WiFi communications mechanism in which simultaneous transmission is negotiated and beamforming communications performed towards at least one station (STA), while nulling is performed towards one or more other access points (APs) to reduce interference. Omni-directional transmissions are utilized in a manner to overcome preamble interferences, which is used in combination with synchronizing symbol intervals to eliminate interference from symbol transitions. The enhanced simultaneous transmission protocol allows two APs to transmit simultaneously without interfering with one another.
