  • Patent number: 7734978
    Abstract: A receiver capable of switching between a NormalAck scheme that includes an acknowledgement for a single frame in one frame and a BlockAck scheme that includes an acknowledgement for a plurality of frames in one frame. The receiver regards the use of the BlockAck scheme to have been terminated and releases resource being used for the BlockAck scheme and switches to the NormalAck scheme if a data frame requesting the BlockAck scheme is not received within a predetermined period regardless of whether the receiving station has or has not received a data frame requesting the NormalAck scheme.

  • Publication number: 20100020681
    Abstract: Provided is a communication apparatus by which a user can simply set a transmission quality in a network and QoS control effectively functions. QoS type receiving sections (11, 21, 31, 41) are arranged in communication apparatuses (10, 20, 30, 40) on a network, and a user is permitted to specify a QoS type to be requested to the communication apparatuses (10, 20, 30, 40), by operating the QoS type receiving sections (11, 21, 31, 41). When the communication apparatuses (10, 20, 30, 40) perform communication, the network is controlled to ensure the QoS corresponding to the QoS type received by the QoS type receiving sections (11, 21, 31, 41).

  • Patent number: 7620713
    Abstract: Control commands are sent from communication stations (A, B) to devices (D to F), such as a VTR, connected to a communication station (C) via radio networks (NW) provided between the communication stations (A, B) and the communication station (C), thereby controlling the devices (D to F). As a result, video signals outputted from the devices (D to F) via analog wirings (W) are sent from the communication station (C) to the communication stations (A, B) so that videos based on the video signals are displayed in display devices (A11, B11) via the communication stations (A, B). In the communication station (C), identifiers for specifying controllers (A1, B1) which have sent the control commands to the communication stations (A, B) and identifiers for specifying the devices (D to F) controlled are made to respectively correspond to each other, and are stored so that a controller which can be allowed to control is specified.

  • Publication number: 20090122768
    Abstract: In the present invention, when a CP is extended longer than that of a preset schedule, a CP having been set in a subsequent schedule cycle in the preset schedule is omitted until the delay is recovered, that is, until the preset schedule and an actual schedule are synchronized with each other. In case where the CP indicative of a period for executing a communication method in which a QAP does not manage spectrum allocation is extended longer than a period the QAP has set in the preset schedule, subsequent spectrum allocation in a QAP delays from the schedule, so that a power save efficiency of a QSTA drops. The foregoing technique suppresses the drop of the power save efficiency.

  • Publication number: 20070162813
    Abstract: The current Draft IEEE 802.11e standard specifies two types of schemes for obtaining an acknowledgement from a receiving station: BlockAck and NormalAck. The current specifications allow temporary use of NormalAck while transmitting data frames in a BlockAck scheme. The specifications however does not explicitly describe the data frames that are allowed to be transmitted using NormalAck. Should these data frames follow the same rules as in BlockAck schemes, and if the transmitting station has dynamically switched between these two types of schemes, the receiving station can know only with extended delays that unreceived data frames are no longer valid. Therefore, the passing of subsequent, successfully received data frames from the receiving station to an upper layer may be significantly delayed, which is a problem.

  • Patent number: 7157319
    Abstract: A high-precision patterning is conducted with a half-tone resist thickness being prevented from varying due to the presence/absence of a base film. A transmitting portion and two kinds of semi-transmitting portions, providing different quantities of transmitted light, are provided in a photomask for exposing a resist, and a smaller-transimitting-light-quantity semi-transmitting portion is used in a base film-present area and a large-transmitting light-quantity semi-transmitting portion is used in a base-film-free area to regulate luminous exposure while exposing, thereby forming a half-tone resist having uniform thickness.

  • Publication number: 20060155856
    Abstract: A communications device (non-AP QSTA) transmits a request signal to a central control device (HC) so as to establish downlink stream communications from the central control device to the communications device. The request signal indicates a request for an ACK information specify process related to group ACK. The central control device receives, from the communications device, the request signal indicating a request for an ACK information specify process. The central control device transmits, to the communications device, a response signal to the request signal indicating a request for an ACK information specify process. The communications device receives the response signal from the central control device.

  • Publication number: 20050183115
    Abstract: When the operator pushes a switching button provided on a controller, a local communication station selects a remote communication station in accordance with a predetermined order, and in the remote communication station, a device is selected in accordance with a predetermined order. When the operator pushes the switching button provided on the controller again, a message that switching to all devices in the remote communication station has been completed is transmitted to the local communication station, and in accordance with the foregoing order, a remote communication station, which is a remote communication station to be selected next, is selected. In the remote communication station concerned, a device is selected in the same manner in accordance with a predetermined order. With this arrangement, it is possible to easily select a desired content even if contents such as devices are located at a plurality of stations in a dispersed manner.
