摘要： In a cellular radio communication system, a base station or a mobile station has a TA (Time Alignment)-range-out detection function, so that when a TA-range-out state that is unable to compensate with a guard interval is detected, the transmission condition of an uplink signal at the mobile station is changed by the mobile station autonomously or by the base station and the mobile station cooperatively.

摘要： Even though a network with communication rate large fluctuations is applied to a remote monitoring system, data communication delay time is kept smaller for which a shorter communication delay time is demanded and a high throughput is implemented. A sensor equipped terminal sends measurement data to a network interconnection device. A priority level determining unit of the device sorts the data into first data necessary to be delivered to a monitoring center within requested communication delay time and second data not necessarily to be delivered to the center within requested communication delay time. A transmission buffer unit is a buffer storing the first and second data accumulated in first and second data accumulating units in sending the data to a wide area network by FIFO. A transmission control unit dynamically controls a rate in causing the data to come in the transmission buffer unit based on a network communication rate.

摘要： Provided is a wireless communication system, comprising: a wireless communication apparatus which performs adaptive modulation for changing a modulation method and an encoding rate of a data channel, and transmits/receives a signal via MIMO multiplexing. The control information comprises first control information to be used for a MIMO stream separation process and second control information not to be used for the MIMO stream separation process. The selections in the second control information are changed corresponding to selected first control information. The wireless communication apparatus determines the first control information at an update timing of the first control information by referring to the first control information table, determine selections of the second control information based on the determined first control information, and select one of the selections of the second control information among the determined selections of the second control information at an update timing of the second control information.

摘要： In a remote monitoring system including a monitoring center, a sensing information collecting station, and one or more sensing terminals, the sensing information collecting station collects measurement results measured by the sensing terminals, classifies the collected measurement results into priority information and general information, and transmits priority information and general information to the monitoring center. The monitoring center transmits response information to received priority information to the sensing information collecting station. The sensing information collecting station estimates network condition from a delay time based on the response information and decreases the transmission rate of general information when the estimated network condition is more congested. Thereby, even if the network condition fluctuates, desired information such as statistical information on measurement results and measurement results meeting a predetermined condition is communicated stably at low delay.
