Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to Wi-Fi systems including frame extensions in transmission frames. Lengths of frame extensions may be determined based on transmission bandwidths and transmission data rates of the frames. Lengths of frame extensions may also be determined based on an amount of useful data in a final symbol of the frame. An access point (AP) may determine frame extension lengths for use in transmitting to stations (STAs) based on reception capabilities of the STAs. An AP may determine frame extension lengths for STAs to use in transmitting frames.
