SR Behavior Overview CIDs 11360 Myles 27.9 289.00 802.11ax includes two spatial methods. Both methods are relatively complex and there are doubts about how well they work. It appears both are included because of these doubts.. Presumably the hope is that one mechanism does actually work. However, standards are supposed to be generally about standardising proven mechanisms (preferably one to reduce complexity and risk) or mechanims that are known to work rather than standardising experiments. The 802.11ax draft should be modified to remove at least one of the SR mechanisms. The TG should be confident that the remaiing mechanism actually works. If not then both mechanisms shoukd be removed. Reject – There is no doubt that the SRP SR mechanism is effective when an opportunity to use it is identified. The SRP mechanism relies on measured information that might be subject to some error, but engineering always must include margin for error. The OBSS PD SR mechanism has been proven, in various situations, through simulation, to be effective in producing good outcomes. The standard of quality of the evidence presented in support of the OBSS PD SR mechanism is no different than the standard that has been applied to various other features and functions which have been included in previously approved 802.11 standard amendments, and there are other features that have been included in the past that have been included with a much lower bar of quality of evidence. 11357 Alfred 27.9 289.54 It is still difficult to understand what values of the SIG-A related to which of the features.
