摘要： A data rate is to be determined depending on circumstances. A control unit (30) transmits, at a predetermined frequency, a request signal by which to supply information on a data rate to a targeted radio apparatus compatible with a variable data rate. The control unit (30) receives rate information from the targeted radio apparatus. The control unit (30) sets a data rate used in the case of transmitting data, based on the information on a data rate contained in the rate information. The control unit (30) identifies the reliability level of the data rate contained in the rate information. And when the reliability level is low, the control unit (30) lowers the frequency at which the rate request signal is transmitted.

摘要： A correction unit corrects the phases of received multicarrier signals, respectively, carrier by carrier. A combining unit and a computing unit performs adaptive array processing on the corrected multicarrier signals on a carrier-by-carrier basis. A derivation unit derives, carrier by carrier, a phase for correction to be used by the correction unit, based on error in the multicarrier signals which have undergone the adaptive array processing. The derivation unit updates a frequency for correction about a carrier to which a known signal is assigned, based on error in the carrier, so as to derive a phase for correction and the derivation unit also derives a phase for correction, based on the error in the carrier and the phase for correction in a carrier to which the known signal is assigned.

摘要： A packet communication unit (20) executes radio communications in such a manner as to be accessible to other terminal apparatuses that have already been communicating wirelessly with a base station apparatus. The signal processing unit (22) generates a connection request signal to be transmitted from the packet communication unit (20) to the base station apparatus by way of the other terminal apparatuses. The signal processing unit (22) processes a connection response signal received, from the base station apparatus, by the packet communication unit 20. Such a sequence of operations allows the signal processing unit (22) to perform connection processing between a terminal apparatus and the base station apparatus.

摘要： Using as a reference a known signal assigned to one of a plurality of streams that constitute a packet signal, a control unit applies a cyclic timing shift to known signals assigned to the other streams so as to produce packet signals which are to be transmitted finally. While varying the amount of timing shift, the control unit produces a plurality of packet signals and appends an identification number, with which to uniquely identify each of the plurality of produced packet signals, to each of the packet signals. A baseband processing unit and the like transmit, as a transmission rate inquiry signal, a packet signal constituted by a plurality of streams where the amounts of timing shift are made to differ, and receive a response signal to which the same identification number is appended for the inquiry signal.
