| Variable bandwidth assignment and frequency hopping are employed to make efficient use of radio resources. Variable bandwidth assignment is achieved by dynamically allocating different numbers of subcarriers to different mobile terminals depending on their instantaneous channel conditions. The frequency hopping patterns are determined "on-the-fly" based on the current bandwidth assignments. The bandwidth assignments and frequency hopping patterns are signaled to the mobile terminals in a scheduling grant. | ||||||

A base station determines both a transmission interval between scheduling requests which a mobile station transmits before transmitting uplink data and information about radio resources used for transmitting the scheduling requests, based on the status of the mobile station and/or QoS information transmitted from the mobile station. The mobile station generates the scheduling requests. The mobile station controls the transmission of the scheduling requests based on the transmission interval and the radio resources. The mobile station transmits the scheduling requests. The base station detects correlation based on the scheduling requests which are transmitted from the mobile station based on the transmission interval and the radio resources, and feeds delay information back to the mobile station. The mobile station maintains synchronization based on the delay information transmitted from the base station. |

| A high-speed transmission of massive data is performed between a device having a card read/write function and an information terminal wired with an IC card. An information processing terminal defines a data transmitting state allowing a noncontact data communication through the IC card and a data untransmitting state not allowing that noncontact data communication, and the IC card manages the communication state of the information processing terminal. The IC card can perform the data transmission to the terminal side, in dependence upon not the notice from the information processing terminal but whether or not the data is transmitted, so that the synchronization can be easily taken to raise the transfer speed thereby to realize the massive data transmission. | ||||||

| An amplifier circuit performs an amplification of a carrier signal received by a transmitting and receiving unit. The amplifier circuit includes an impedance matching circuit that performs matching of an impedance of the amplifier circuit when the transmitting and receiving unit and the amplifier circuit are connected. A superposition wave generating unit generates a superposition wave which is superimposed on the received carrier signal. A driver outputs an amplified carrier signal which is obtained by adding the superposition wave to the received carrier signal. An amplitude detecting unit detects whether the received carrier signal is a predetermined carrier signal superimposed with a predetermined communication signal, based on changes of an amplitude value of the received carrier signal. When the predetermined carrier signal is detected, the amplifier circuit outputs the amplified carrier signal. | ||||||

| The present invention aims to overcome the drawback with conventional RFID tag devices having a short communication range, and expand the communication range to several times or more that in the conventional scheme. The conventional scheme is based on equilibrium feeding/equilibrium modulation (a two-terminal circuit for antenna operation), whereas the present invention is based on disequilibrium feeding/equilibrium modulation (a three-terminal circuit for antenna operation). The conventional scheme is based on simple rectification of received RF signals, whereas the present invention employs a circuit based on a combination of a stub resonance-based, impedance transformation boosting scheme and a ladder boosting scheme. The conventional scheme is based on ASK or BPSK modulation, whereas the present invention is based on passive modulation, but can employ a QPSK modulation circuit. | ||||||

| A communication device includes a communicator that communicates with an RF tag in a non-contact manner, a communication unit that exchanges data with a host device, and a controller that controls the communicator and the communication unit. Every time the communicator sequentially reads data from the RF tag that passes a communication-feasible region near the communicator at regular time intervals or irregular time intervals, the controller updates first data to be exchanged with the host device by the communication unit so as to include the read data. Also, the controller updates second data to be exchanged with the host device by the communication unit to a value different from a previous value in association with timing with which the first data is updated. | ||||||

| A waveform synthesis technique for radio frequency identification (RFID) transmitters and an RFID system making us of the technique are disclosed. The RFID transmitter in example embodiments synthesizes a continuous transmitter waveform from a symbol alphabet without Nyquist or interpolation filters. High spectral occupancy waveforms are achieved which include the ability to do both linear and nonlinear predistortion with no increase in computational load once the signal set has been adapted to compensate for linear and nonlinear distortion in the transmitter analog circuitry. A polarity generator can be used to impart the required polarity to each waveform. The RFID transmitter can be employed in RFID readers to reduce the computational requirements of the digital signal processor (DSP). | ||||||

| A method for determining the time of receipt by a radio receiver of a binary coded radio message emitted by a sender. A radio signal containing the message is received by the receiver. An analog electrical signal is generated, sampled and optionally demodulated. The data content of the message is determined based upon the demodulated signal as a stream of data bits. The stream of data bits comprises a predetermined signal element whose time of receipt is determined. A digitally stored, constructed comparison signal is created based upon the stream of data bits. The constructed comparison signal is constructed to correspond to the sampled signal, in that a time variable which maximizes a correlation between the constructed comparison signal and the sampled signal is determined, and in that the time variable is then used to correct the time determination of the receipt of the predetermined signal element. | ||||||
