Abstract
Certain aspects of the present disclosure provide an apparatus for wireless communications. The apparatus generally includes a processing system configured to generate a frame for triggering transmission of a plurality of data units from a plurality of wireless nodes, a first interface configured to output the frame for transmission to the plurality of wireless nodes, and a second interface configured to obtain the plurality of data units after outputting the frame for transmission, wherein the plurality of data units have different lengths.

An apparatus for wireless communication, comprising:
- a first interface configured to obtain a frame for triggering a transmission of a data unit and an indication of a common length of a plurality of data units;
- a processing system configured to:
- determine whether to use a length of the data unit that is less than the common length;
- and
- generate the data unit in response to obtaining the frame, the length of the data unit being based on the determination;
- and
- a second interface configured to output the data unit for transmission.

A station, comprising:
- at least one antenna;
- a first interface configured to obtain, via the at least one antenna, a frame for triggering a transmission of a data unit and an indication of a common length of a plurality of data units;
- a processing system configured to:
- determine whether to use a length of the data unit that is less than the common length;
- and
- generate the data unit in response to obtaining the frame, the length of the data unit being based on the determination;
- and
- a second interface configured to output the data unit for transmission via the at least one antenna.
An apparatus for wireless communication, comprising:
- a processing system configured to generate a multi-user (MU) packet comprising one or more data units, wherein a length of at least one data unit of the one or more data units is less than an advertised length of the at least one data unit, the at least one data unit indicating the advertised length;
- a first interface configured to output the MU packet for transmission to a plurality of wireless nodes;
- and
- a second interface configured to obtain, from the plurality of wireless nodes, one or more packets having one or more acknowledgement frames, each of the one or more acknowledgement frames indicating whether a respective data unit of the one or more data units was successfully decoded.
