1) 802.11ax Performance analysis mentioned in this research paper should be studied also from scheduled access/SA mode and Random access/RA mode perspective.

2) Although the 802.11ax throughput is increased with the increase to 512 clients the "delay response" mentioned for both 802.11ac and 802.11ax could be explored in detailed manner in terms of NS3 based mathematical modelling as there are many other variables which will define this performance number.

Both IEEE 802.11ax Mcs-11 and IEEE 802.11ac Mcs-9 with small client number i.e. 2 and 4 clients have the same good throughput value. Simulation with the 16 to 512 clients IEEE 802.11ax has bigger throughput value than IEEE 802.11ac. At medium client number, both IEEE.802ax Mcs11 and IEEE 802.11ac Mcs-9 shown similar delay response time, but IEEE 802.11ax has a bigger throughput value than IEEE 802.11ac

3) What is the implication of 802.11ax performance when the Contention Window/CW size is changed dynamically is another important aspect to be studied in detailed manner as there are some optimum CW values which could be selected in 802.11ax performance.

4) The performance analysis studies done in Fig 10) and Fig 11) are good but it should be studied further to derive the comparitive analysis of 802.11ac with 802.11ax technology.

5) The usage of the TCP New-Reno protocol as a transport layer protocol in this 802.11ax versus 802.11ac based performance analysis study could be avoided as diferent flavours of TCP could give different performances. MPTCP or other TCP variants have some changes in L4 which might transpire into better performance for 802.11ac PHy and MAC layer but in actual case the performance of 802.11ax is better. Hence TCP-reno could be avoided.

Areas of improvement as per reviews:

There are some important parameters which could be considered in this performance case study. a) usage of adaptive ED thresholds in CSMA technique with #XYZ number of 802.11ax clients and some other number of 802.11ac clients , so on. SA(sched access) versus RA access (random mode) should be included, usage of RU's in UL MUMIMO for OFDMA's performance improvement can be explained in detailed manner.
