This paper studies the throughput of the IEEE 802.15.3c millimeter-wave (mm-Wave) WPAN system that is based on the hybrid multiple access of CSMA/CA and TDMA. In order to study the throughput of this system, we construct a novel analytical model by considering hybrid multiple access. Our throughput analysis shows that the throughput is significantly affected by the length of access time of CSMA/CA. A large length of access time of CSMA/CA will cause a low data transmission time in TDMA, while a short length of access time of CSMA/CA will cause a large number of data transmission collisions in CSMA/CA. The failure of data transmission channel release due to the collisions will lead to an increase in the unused data transmission time in TDMA. In order to improve the throughput, we introduce a private channel-release time to avoid the failure of data transmission channel release and provide the optimum access time of CSMA/CA, thereby maximizing the throughput. The proposed method can significantly improve the throughput of the IEEE 802.15.3c mm-Wave WPAN system.
