ADAS: Adaptive Switching between Full-Duplex and MU-MIMO for Wi-Fi Networks

Figure 1

Cases of inefficient transmission in FD and MU-MIMO. (a) The case in which the AP initiates an FD transmission when it wins the channel contention. If the transmission time of the receiving node is too long, the AP may have to wait a longer time to send the next frame than when FD is not used; (b) if the data for transmission is not sufficiently large, the CSI overhead may overwhelm the gain from MU-MIMO.
