Abstract: A first communication device determines that a trigger frame and another frame are to be transmitted to at least a second communication device. The first communication device determines whether the second communication device announced support of aggregation of buffer status report (BSRP) trigger frames with additional frames. In response to the first communication device determining that the second communication device announced support of aggregation of BSRP trigger frames with additional frames, the first communication device generates an aggregate media access control protocol data unit (A-MPDU) to include the BSRP trigger frame and the other frame, and transmits the A-MPDU within a packet. In response to the first communication device determining that the second communication device did not announce support of aggregation of BSRP trigger frames with additional frames, the first communication device transmits a packet having only the BSRP trigger frame.
