    Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an AP, that reduce the overhead associated with triggering an uplink transmission from the STA. In some examples, the STA may also calculate its transmit power by decoding a spatial reuse subfield of the trigger frame from the AP and identifying downlink pathloss measurements of the trigger frame. Accordingly, the STA may identify acceptable interference level of the AP and calculate a transmit power in order to minimize interference at the AP. In some aspects, the STA may transmit its uplink packets to a different AP on one or more punctured channels at the calculated transmit power of the STA.

    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.

    Abstract: Systems and methods for wireless communications are disclosed. More particularly, aspects generally relate to techniques for indicating a minimum and maximum channel bandwidth in a frame (e.g., short frame). One or more bits in the frame, for example a management frame, may indicate both minimum and maximum bandwidths for communicating in the network. According to aspects, a wireless terminal may determine the minimum and maximum bandwidths for communicating in the network based on a mapping of different values of the one or more bits to combinations of minimum and maximum bandwidths. While any field in the frame may indicate the minimum and maximum bandwidth, according to aspects, the Basic Service Set (BSS) bandwidth (BW) field may be used for the indication.
