Abstract: A communication apparatus determines whether or not the communication apparatus and one or more other communication apparatuses capable of performing coordinated communication by coordinating with the communication apparatus to use a predetermined frequency band can obtain channel state information from one or more communication partner apparatuses that perform the coordinated communication, and selects a communication method for performing the coordinated communication from among a plurality of communication methods based on a result of the determination.

Abstract: A communication apparatus receives a radio frame complying with an IEEE802.11 series standard, acquires information of a WUR (Wake-up Radio) Discovery element included in the received frame, and decides, based on the information of the WUR Discovery element, a WUR channel used to wait for a WUR Discovery frame.

Abstract: A communication apparatus transmits a frame including frequency band allocation information for communication based on Orthogonal Frequency Division Multiple Access (OFDMA), and determines whether to permit or prohibit Spatial Reuse Parameter (SRP) based communication in accordance with a communication partner apparatus of each of a plurality of terminal stations in a network managed by the communication apparatus. The communication apparatus, in a case where it is determined that the SRP based communication is to be prohibited, transmits the frame including information indicating that the SRP based communication is prohibited.

Abstract: A communication device, which complies with an IEEE802.11 standard and performs communication by assigning an Association identifier (AID) to a partner device, determines the AID to be assigned to the partner device from a first range of AID values if the partner device is a first device compatible with a frame that is transmitted with a destination designated by a range of the AID, and determines the AID to be assigned to the partner device from a second range different from the first range if the partner device is a second device not compatible with the frame that is transmitted with the destination designated by the range of the AID.

Abstract: A communication apparatus that includes a transceiver capable of communicating with the first another communication apparatus operable in accordance with information of a schedule for causing another communication apparatus to operate in a communicable state and the second another communication apparatus inoperable in accordance with the information on the schedule is provided, the information being contained in a first radio signal transmitted by the communication apparatus. The communication apparatus controls, by the schedule, the transceiver so as to transmit the second radio signal for limiting transmission of a radio signal by the second other communication apparatus in at least a part of a period in which the first other communication apparatus operates in a communicable state in a case where the first radio signal is transmitted.

Abstract: In order to solve at least one of the problems that occur if connection cannot be established with some of a plurality of other communication apparatuses, a content transmission apparatus accepts an instruction for content playback using a plurality of other communication apparatuses; determines that communication connection cannot be established with some other communication apparatuses of the plurality of the other communication apparatuses; and performs a predetermined notification to a user in response to determination that the communication connection cannot be established with the some other communication apparatuses of the plurality of the other communication apparatuses.

Abstract: A communication apparatus having a first communication function of periodically transmitting a predetermined signal and communicating with another apparatus and a second communication function of communicating with another apparatus by producing an electric field or magnetic field determines whether a partner apparatus exists in a communicable range of the second communication function, and controls the first communication function to stop transmission of the predetermined signal in the case where it is determined that the partner apparatus exists in the communicable range.

Abstract: A communication control system constituted by a communication terminal, a management apparatus that manages the communication terminal, and a wireless communication network in which the communication terminal and the management apparatus are communicable with each other.

Abstract: A server that provides a plurality of types of content to another device selectively executes a control function or a function of being controlled in response to a type of a request from the other device, the request requesting the server to provide at least one of the plurality of types of content, and an operational status of the control function or the function of being controlled. The control function is a function of a controller that establishes and controls a wireless network. The function of being controlled is a function of a controlled component in a wireless network established and controlled by another controller.

Abstract: In a managing device in a communication system including both a first terminal that carries out a control procedure with the managing device and starts data communication, and a second terminal that starts data communication without carrying out the control procedure, the start of data communication by the second terminal is recognized. Then, after recognizing the start of the data communication by the second terminal, when the start of a control procedure is requested from the first terminal, the control procedure is changed.

Abstract: A server that provides a plurality of types of content to another device selectively executes a control function or a function of being controlled in response to a type of a request from the other device, the request requesting the server to provide at least one of the plurality of types of content, and an operational status of the control function or the function of being controlled.

Abstract: A telephone control apparatus connected to an exchange accommodating a plurality of lines. The apparatus calls a connected communication terminal in accordance with a calling signal inputted from the exchange. In the apparatus, response information corresponding to the type of calling signals is stored in RAM 12 in advance. The type of a calling signal inputted from the exchange is discriminated, and response information is read out of the RAM12 in accordance with the discrimination result, to determine a corresponding response process. Further, a telephone exchange apparatus which accommodates a plurality of outside lines and which selects and seizes one of the outside lines by outgoing calling from an extension. Upon outgoing call operation from an extension, the stored information is referred to and one of the plurality of outside line is selected based upon a number of incoming calls received on each of the outside lines or the time period each one of the outside lines has been occupied in communication.
