Methods, apparatuses, and computer readable media for initial control frames with block
acknowledgement request, where a STA comprises
processing circuitry configured to: decode, from an access point (AP), an ultra-high reliability (UHR) buffer
status report poll (BSRP) trigger frame, the BSRP trigger frame including a
user information field, the
user information field comprising an association identification (AID) field, the AID field indicating an AID of the STA, and the BSRP trigger frame including a common
information field, the common
information field comprising a field, the field indicating a format of a response from the STA, in response to the field indicating the format of the response from the STA is a non-HT duplicate PPDU,
encode, for transmission to the AP, the non-HT duplicate PPDU, and in response to the field indicating the format of the response from the STA is a PPDU,
encode, for transmission to the AP, the PPDU.
