Abstract: The present technology relates to a wireless communication apparatus and method by which communication can be performed with a higher efficiency. The wireless communication apparatus includes a preamble generation section that generates a preamble that is to be deployed at the top of a transmission frame and includes header information, a midamble generation section that generates a midamble that is to be deployed in the middle of the transmission frame and includes information of at least part of the header information, and a wireless transmission processing section that transmits the transmission frame including the preamble and the midamble. The present technology can be applied to a wireless communication apparatus.

Abstract: Provided is a communication device that favorably implements SR communication and MU communication. A communication device that operates as a base station includes a determination unit that determines a communication status in a BSS of the communication device, and a control unit that controls transmission and reception of a signal regarding connection change of a terminal according to the communication status to and from a surrounding base station. The determination unit determines the presence of a small number of terminals falling outside a distribution of implementation statuses of spatial reuse communication or multi user communication of entire subordinate terminals, and transmits a signal requesting the small number of terminals to be connected to the surrounding base station or transmits a signal inquiring of the surrounding base station acceptance of the small number of terminals.

Abstract: A communication device and a communication method for allowing a communication terminal to be able to search for access points within a short time are provided. A communication device operating as an access point in a wireless network transmits a beacon signal at a predetermined beacon interval on an operation channel selected from available frequency channels. In addition, the communication device performs data transmission and data reception to/from a communication terminal subordinate thereto on the operation channel, and transmits a notification signal including information about the operation channel while switching channels at each predetermined cycle in available frequency channels other than the operation channel.

Abstract: The present technology relates to a wireless communication apparatus and a wireless communication method that make it possible to read necessary information even in a case where a physical header at a top portion of a signal transmitted from a base station of another BSS fails to be received and the signal is received from the middle. The wireless communication apparatus includes a communication section configured to generate and transmit an OFDM signal in which second information is superimposed in a frequency axis direction of the OFDM signal which includes first information destined for one or more subordinate client devices. The present technology can be applied to a wireless communication apparatus and so forth that perform wireless communication, for example, standardized by IEEE 802.11.

Abstract: [Problem] It becomes possible to realize more efficient communication in a wireless local area network (LAN) system. [Solution] There is provided a wireless communication device that functions as an access point of a wireless LAN, including: a generation unit that generates a wireless signal in which allocation information for allocating a plurality of stations to one resource unit is stored; and a transmission unit that transmits the wireless signal to the stations.

Abstract: The present technology aims to achieve flexible transition of a communication apparatus from a centralized communication mode to another mode. A communication apparatus includes: a transition information generation unit that generates a plurality of pieces of different transition information related to transition from a first mode in which centralized communication is performed by an access point to a second mode in which no centralized communication by an access point is performed; and a frame generation unit that generates a frame containing the transition information.
