Abstract
When a transmission station having a voluntary transmission right transmits FINALL FRAME as a TXOP ending frame to HC, the HC transmits an acknowledgement frame ACK after SIFS following the reception of FINAL FRAME. Here, when the transmitting station has detected that no frame transmission is performed over the communication network from any other ESTAs in PIFS after the transmission of FINAL FRAME, FINAL FRAME is retransmitted in DIFS after the transmission of FINAL FRAME. By performing such a communication management, it is possible to accurately manage a voluntary transmission right even when the communication medium has a low reliability in a network in which one network pathway is time-shared by a plurality of communication apparatuses.
