MU-MIMO enabled uplink OFDMA MAC protocol in dense IEEE 802.11ax WLANs
IEEE 802.11ax supports orthogonal frequency division multiple access (OFDMA) for uplink (UL) transmissions where stations (STAs) access randomly chosen resource units (RUs) in a distributed manner. Nevertheless, as the number of STAs increases, frequent collisions can occur, which lead to throughput...
