Methods are provided for concurrent communications among multiple wireless communications devices. In one novel aspect, the wireless station transmits a wideband signal to a plurality of wireless communications devices using downlink MIMO and/or OFDMA. The wireless station receives a plurality of responding frames from the plurality of wireless communications devices concurrently using OFDMA. In one embodiment, the wireless station transmits a MU indication bit and MU bandwidth assignment information in the downlink MIMO and/or OFDMA frames. In another novel aspect, the uplink responding frames from multiple wireless communications devices are sent on a corresponding narrow concurrently over more than one transmission instance. AP polling or SIFS only is used between two transmission instances. When the concurrent responding frames occupies less than a bandwidth of an available uplink OFDMA bandwidth, the unoccupied bandwidth is either left empty or occupied by one or more duplicated responding frames.
