摘要： A spreading code generating apparatus carries out M-sequence multiplication and zero value addition of generated orthogonal codes to obtain channel identification codes, and then carries out inverse Fourier transform of the channel identification codes to generate spreading codes and inverse spreading codes. A transmitting apparatus and a receiving apparatus store the spreading codes and the inverse spreading codes generated by the spreading code generating apparatus, respectively, and use a single code respectively selected from the stored codes to carry out spread spectrum communication. With the use of the spreading codes for spreading, the input signal is spread over a wide frequency band with uniform power on the frequency axis. Thus, transmission characteristics are improved, and multiplexing capacity is increased.

摘要： In serial transmission of a mixture of isochronous data and anisochronous data, communications through a transmission path with a high ratio of occurrence of transmission errors may disturb images during streaming reproduction and produce noise in sound. To solve this problem, the isochronous data that has not been successfully received is retransmitted by using an anisochronous region. Thus, a transmission error of the isochronous data can be reduced without impairment of isochronous characteristics of the data.

摘要： A method, performed by an access point controls transmission of a data stream from a station, by determining whether or not to admit the transmission of the data stream. The method includes receiving, from the station, a QoS registration request frame, indicating a request for transmission of a data stream, and including information indicating a QoS requirement comprising information indicating a required interval between a start of two successive time periods during which the station is permitted to transmit the data stream. A schedule for the transmission of the data stream subject to the QoS requirement is calculated when the transmission is admitted and a QoS registration response frame, including information indicating the schedule is transmitted to the station.

摘要： A station includes a reservation request transmitter, a bandwidth request transmitter, and a data transmitter. The reservation request transmitter transmits a reservation request to an access point during a contention slot specified by the access point. The contention slot is periodically allocated by the access point. The bandwidth request transmitter transmits a bandwidth request to the access point using a first allocated bandwidth allocated to the station as a response to the reservation request. The bandwidth request has a first data structure different from a second data structure of the reservation request, and includes information indicating a required bandwidth for transmitting a data to be transmitted. The data transmitter transmits the data using a second allocated bandwidth allocated to the station based on the required bandwidth.

摘要： Method and apparatus for controlling transmission of a data stream from a station. A QoS registration frame is received, via an access point, from the station. The QoS registration frame includes information indicating a request for transmission of a data stream from the station, and information indicating a minimum required interval and a maximum required interval for an interval which is between start points of two successive durations of a medium dedication. Each duration of the medium dedication represents a time period in which the station is permitted to transmit the data stream. A schedule for the transmission of the data stream is calculated by setting a new interval which is between the minimum required interval and the maximum required interval, when the transmission is admitted. A QoS response frame, which includes information indicating the schedule, is then transmitted from the access point to the station.
