Patent ID: 8040837

Claim:
A wireless communication apparatus, comprising: a demodulation unit operable to demodulate a received signal to obtain demodulated data; a link information management unit operable (i) to extract received-signal strength information and required-CIR information from the demodulated data, (ii) to obtain a CIR estimate value by estimating a CIR of a second wireless station in a case where the wireless communication apparatus interferes with the second wireless station based on the extracted received-signal strength information, and (iii) to judge whether or not a link of the received signal is concurrently allowable with a link of a signal to be transmitted based on the required-CIR information and the CIR estimate value, where the link of the received signal is data transmission between a first wireless station and the second wireless station; a concurrent transmission link management unit operable (i) to store therein, when the link information management unit judges that the link of the received signal is concurrently allowable with the link of the signal to be transmitted, wireless station identifier information, included in the demodulated data, of the link of the received signal, (ii) to judge whether or not the link of the received signal is concurrently allowable with the link of the signal to be transmitted by comparing the wireless station identifier information of the link of the received signal with wireless station identifier information of links of previously received signals, each of which having been stored in the concurrent transmission link management unit based on a result of a judgment by the link information management unit, and (iii) to generate and output a concurrent transmission timing signal based on a result of the judgment by the concurrent transmission link management unit; and a transmission unit operable to transmit a signal according to a timing that overlaps reception of the received signal based on the concurrent transmission timing signal received from the concurrent transmission link management unit.
