“…Additionally, Sangdeh and Zeng [144] address joint MU-MIMO and OFDMA optimization by using deep supervised learning (DSL). The solution, called DeepMux, is executed at the APs and relies on DNNs to minimize the impact of channel sounding and find a near-optimal resource allocation policy.…”

“…This DNN-based WiFi control strategy achieves significant improvements in system throughput, average transmission delay, and packet retransmission rate. In order to improve the efficiency of downlink MU-MIMO-OFDMA transmission in 802.11ax networks, a deep learning-based channel detection (DLCS) and deep learning-based resource allocation (DLRA) approach is proposed in the literature [30]. DLCS utilizes the compression capability of DNN to compress the frequency domain CSI during the feedback process.…”

“…We store the raw angle values (before converting to the corresponding quantized index) of all the Ψ angles for all the subcarriers of all the simulated packets. From this generated data, we obtain the 50th percentile values of all the Ψ angles and use them as our fixed values instead of computing them for the compressed beamforming representation as shown in (6). The beamformee and the beamformer both will have complete information about the fixed vector of the Ψ angle values.…”

“…An alternative approach to reduce the amount of information required in beamforming feedback is to transmit partial compressed beamforming feedback information. In the compressed beamforming methodology described in Section III, information about two types of angles is transmitted as the beamforming feedback, namely, Φ in (5) and Ψ in (6). However, if only Φ angle information is transmitted in the feedback, the number of angles that need to be reported in the feedback is halved.…”
