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 plurality of sensor devices that senses environmental data at installation positions is appropriately arranged. Each sensor device includes a device detection unit, a position fixing unit, a sensor unit, and a transmission unit. The device detection unit performs operation of detecting another sensor device in the surrounding area and generates a detection result thereof. The position fixing unit fixes a position of the own sensor device on the basis of the detection result obtained by the device detection unit. The sensor unit senses environmental data at a position fixed by the position fixing unit. The transmission unit transmits the data sensed by the sensor unit.

Abstract: To provide an excellent communication apparatus and communication method which operates with a basic service set belonging to an extended service set. A wireless terminal transmits a frame in which BSS-color and ESS-color which respectively identify a BSS and an ESS to which the own wireless terminal belongs are described. Further, part of a region for storing ESS-color is used as a region for storing BSS-color to secure the number of pieces of BSS-color sufficient to avoid overlapping. An STA stores statistical information regarding a received frame in association with BSS-color and ESS-color and performs cooperative operation within the ESS or between the ESSs.
