Abstract: Devices and methods are provided to modify block acknowledgement (BA) and/or block acknowledgement response (BAR) control frames to allow for signalling in the reverse direction (RD) process. The new BA and/or BAR control frame uses previously unused fields that are ignored in directive multi-gigabit (DMG) and enhanced DMG (EDMG) networks. The unused fields are repurposed to include a RD Grant (RDG) and an indication that an aggregated media access control (MAC) protocol data unit (MPDU) (A-MPDU) will follow (the indication is referred to as a More PPDU). The change in the BA and/or BAR frame(s) eliminates the need to send a quality of service (QoS) null frame that is typically sent with the BA and/or BAR frame(s), which improves the efficiency of the RD protocol.
