Block ACK without frame aggregation

Block ACK without frame aggregation

[Ali Abedi]

Hello,

I am interested to know if we can send multiple packets (non-aggregated, 
single packets) and then ask
for a block ACK? I like to know if this functionality has been 
implemented in ath9k or if
it is possible to achieve this with slight code modifications.

What I need:
Frame-SIFS-Frame-SIFS-Frame-SIFS-REQ Block ACK-SIFS-Block ACK

Best,
Ali

I don't think mac80211 supports delayed-BA. :(

I think you should look in earlier drivers from Atheors. Because this
delayed BA for separate packets was introduced before 802.11n in
802.11e perhaps.

Dear Adrian and Kamran,

Thanks for your replies. I think we are not referring to the same concept.
Can you please have a look at the attache diagram. I need the middle one
the immediate BA not delayed BA.


Thanks,
Ali

I don't think the hardware supports immediate-BA. :(
