Apparatuses, computer readable media, and methods for resource allocation signaling in uplink frames in wireless networks are disclosed. An apparatus of an access point including processing circuitry is disclosed. The processing circuitry may be configured to encode a first frame and encode second frames for one or both of DL OFDMA or MU-MIMO. The second frames may include data for a plurality of stations. The processing circuitry may be configured to encode a resource allocation for each of the plurality of stations to transmit one or more third frames comprising an acknowledge to the corresponding one or more second frames in accordance with one or both of OFDMA or MU-MIMO. The resource allocation is to be encoded in one or both the first frame and each of the one or more second frames. The resource allocation in the second frames includes the resource allocation for the corresponding station.
