摘要： The present technology relates to a wireless communication device and method, and a wireless communication terminal and method which allow for increased transmission opportunities using multi-link aggregation.
A communication control device transmits a first parameter and a second parameter. The first parameter is used for setting of communication in which a wireless communication terminal uses a plurality of links. The second parameter is used for setting of communication in which the wireless communication terminal uses a single link. It is possible to apply the present technology to a wireless communication system.-

摘要： A communication device determines a communication quality with a base station, requests a neighboring base station for a transition judgment information to transmit information to become a judgment criterion of the communication quality to be included in a Beacon signal at a stage before the communication quality degrades to an extent that the base station is immediately switched, and selects a base station with which a communication connection should be established on the basis of the transition judgment information included in the Beacon signal transmitted in response to the transition judgment request. The communication device is applicable to a communication system in the wireless LAN.

摘要： The present disclosure relates to a wireless base station and a terminal device that can shorten time required for sounding information collection by a plurality of wireless base stations and suppress deterioration of following accuracy. When a wireless base station as a master performs channel measurement with a terminal device, it is possible to transmit channel measurement frames in wireless base stations including the wireless base station at the same timing or at different timings only by instructing another wireless base station to perform a channel measurement, and also transmitting a Sounding Trigger frame including a transmission timing and a transmission stream of a channel measurement frame once. The present disclosure can be applied to communication systems in wireless LAN.

摘要： To provide a communication apparatus that realizes data sharing and coordinate transmit of shared data. A communication apparatus that operates as an access point includes: a communicating unit configured to transmit and receive wireless signals; and a control unit configured to control communication operations in the communicating unit, the communication operations including a communication operation for sharing data to be simultaneously transmitted to a single communication terminal between adjacent access points and a communication operation for recognizing that sharing of the data has been completed. The control unit is configured to perform control when transmitting the shared data simultaneously with the adjacent access points so as to multiplex the shared data with a transmission stream addressed to another communication apparatus and transmit the shared data as a multi-user multiplexed stream.

摘要： 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.
