Abstract:
1. A radio apparatus for transmitting a packet signal composed of a plurality of streams, the radio apparatus comprising: a generator which uses as a reference a known signal assigned to one of a plurality of streams forming a packet signal and generates a packet signal to be finally transmitted, by applying a cyclic timing shift within the known signal to a known signal assigned to another stream; and a communicator which transmits the packet signal generated by said generator, wherein said generator varies an amount of the cyclic timing shift for each of a plurality of packet signals and appends an identification number, with which to uniquely identify each of the plurality of generated packet signals, to the each packet signal, and wherein said communicator transmits the packet signal, composed of the plurality of streams, whose cyclic timing shift amount is made to differ and to which the identification number is appended, as an inquiry signal on a transmission rate, and receives a response signal to which the same identification number as the inquiry signal is appended and which includes information related to the transmission rate.
