  • Patent number: 8406250
    Abstract: A medium access control method is provided in which a control station transmits one specific frame to terminal stations, thereby arranging a schedule of a data transmission time of the control station and each of the terminal stations and allowing a time zone unused by a station for data transmission to be allocated to another station. The control station transmits a schedule frame having defined therein a time occupied by each of the terminal stations, thereby reducing overhead. Also, the completion of the preceding communication performed by another station is detected, thereby effectively using an idle time of a medium and improving transmission efficiency.
    Type: Grant

  • Patent number: 7773498
    Abstract: A transmitting/receiving apparatus includes a packet construction section for dividing continuous data into a plurality of subpackets, and constructing a packet by concatenating the plurality of subpackets; a modulation transmission section for modulating the constructed packet, and transmitting the modulated packet to another apparatus; a training session execution section for checking channel conditions, when a predetermined condition is satisfied, and changing a modulation rule; and a subpacket transmission confirmation section for confirming whether or not a subpacket included in the transmitted packet is transmitted successfully to the transmission destination apparatus.

  • Patent number: 7768922
    Abstract: A communication terminal device of the present invention includes: a packet classification section 103 for classifying the packets by stream types and destinations; a packet accumulation section 104-107 for accumulating the packets classified by the packet classification section, so as to be separately stored based on classification by the stream types and the destinations; a QoS control section 113 for determining a transmission start requirement based on a QoS parameter which defines a transmission quality of a stream; a transmission control section 108 for determining whether the transmission start requirement is satisfied; a framing section 109 for generating the frame by concatenating the packets accumulated in the packet accumulation section if it is determined by the transmission control section that the transmission start requirement is satisfied; and a transmission section 110 for transmitting the frame generated by the framing section to a destination communication terminal device.
