A method for wireless communication, the method comprising: transmitting a single aggregated physical protocol data unit, APPDU, including at the beginning a single physical layer convergence procedure, PLCP, preamble for all of a plurality of physical protocol data units, PPDUs, packed into the single APPDU, whereby each of the plurality PPDUs comprises a PLCP header and does not comprise a PLCP preamble and there is no short interframe space, SIFS, time duration between the PPDUs packed into the single APPDU, wherein each of the plurality of PPDUs is intended for a different one of a plurality of target apparatuses (101,..., 106; 120a,..., 120f), and characterized in that the PLCP header of each of the plurality of PPDUs is transmitted with a same data rate and a same modulation scheme as the single PLCP preamble, wherein the same data rate is slower than a rate of a data frame of each of the plurality of PPDUs; transmitting, after the single APPDU and after waiting the SIFS time duration, a block acknowledgement request, BAR, message to a first of the plurality of target apparatuses (101,..., 106; 120a,..., 120f) to request acknowledgment of a PPDU of the plurality of PPDUs, said PPDU being intended for the first of the plurality of target apparatuses (101,..., 106; 120a,..., 120f); receiving, after the BAR and after waiting the SIFS time duration, a block acknowledgment, BA, message from the first of the plurality of target apparatuses (101,..., 106; 120a,..., 120f) based on transmitting the BAR message, wherein the BA message indicates successful reception of the PPDU intended for the first of the plurality of target apparatuses (101,..., 106; 120a,..., 120f); and repeating the step of transmitting the BAR message and receiving the BA message for each of the plurality of target apparatuses (101,..., 106; 120a,..., 120f). transmitting a single aggregated physical protocol data unit, APPDU, including at the beginning a single physical layer convergence procedure, PLCP, preamble for all of a plurality of physical protocol data units, PPDUs, packed into the single APPDU, whereby each of the plurality PPDUs comprises a PLCP header and does not comprise a PLCP preamble and there is no short interframe space, SIFS, time duration between the PPDUs packed into the single APPDU, wherein each of the plurality of PPDUs is intended for a different one of a plurality of target apparatuses (101,..., 106; 120a,..., 120f), and characterized in that the PLCP header of each of the plurality of PPDUs is transmitted with a same data rate and a same modulation scheme as the single PLCP preamble, wherein the same data rate is slower than a rate of a data frame of each of the plurality of PPDUs; whereby each of the plurality PPDUs comprises a PLCP header and does not comprise a PLCP preamble and there is no short interframe space, SIFS, time duration between the PPDUs packed into the single APPDU, wherein each of the plurality of PPDUs is intended for a different one of a plurality of target apparatuses (101,..., 106; 120a,..., 120f), and characterized in that the PLCP header of each of the plurality of PPDUs is transmitted with a same data rate and a same modulation scheme as the single PLCP preamble, wherein the same data rate is slower than a rate of a data frame of each of the plurality of PPDUs; transmitting, after the single APPDU and after waiting the SIFS time duration, a block acknowledgement request, BAR, message to a first of the plurality of target apparatuses (101,..., 106; 120a,..., 120f) to request acknowledgment of a PPDU of the plurality of PPDUs, said PPDU being intended for the first of the plurality of target apparatuses (101,..., 106; 120a,..., 120f); receiving, after the BAR and after waiting the SIFS time duration, a block acknowledgment, BA, message from the first of the plurality of target apparatuses (101,..., 106; 120a,..., 120f) based on transmitting the BAR message, wherein the BA message indicates successful reception of the PPDU intended for the first of the plurality of target apparatuses (101,..., 106; 120a,..., 120f); and repeating the step of transmitting the BAR message and receiving the BA message for each of the plurality of target apparatuses (101,..., 106; 120a,..., 120f).
