Hello Simone, 802.11ax followers,

 

I have read the submission 13-1001r7 HEW simulation scenarios document. I have some suggested changes to the submission:

 

Issue #1: Common parameters for all scenarios and scenario specific parameters

 

Each scenario should define:

1.       The topology / the world of the test case, including:

a.      the locations of the APs and the STAs

b.      the channel model and penetration losses

c.      primary channels of the APs or the rule how APs select their primary channel

2.       The traffic that is transmitted and delay and packet loss that is acceptable for the traffic.

 

I am not sure does each simulation scenario need to specify the PHY and MAC parameters. The MAC and PHY parameters could be common for all simulation scenarios. The common MAC and PHY parameters could work as default parameter values. Thus, the reader does not need to remember the MAC and PHY settings for each simulation scenario.

At the moment there are some differences in transmission powers of the STAs and APs. For instance scenario 1 uses 17 dBm for STAs and 23 dBm for APs, while Scenario 2 uses 21 dBm for STAs and 24 dBm for APs. I propose to define that transmission power is the maximum transmission power that devices may use and set it to 21 dBm for STAs and 24 dBm (or 30dBm as in scenario 4) for APs.

 

Issue #2: 13-1001r7 Sections summary at page 7 summarizes the scenarios. Management and Homogeneity parameters are only defined in this table, i.e. they are not present in any scenario descriptions. Does anyone have text to explain the use of these parameters in detailed simulation scenarios descriptions?  At least these parameters could be added to the scenario specific parameters.

 

I can write these changes to 13-1001r7.  Your comments are welcome!

Cheers,

               Jarkko
