6843 John Coffey 274.06 Apparently there are two spatial reuse modes, OBSS_PD and SRP-based. ("Apparently", because both are underdefined.) It is widely understood that having multiple different modes to accomplish the same objective is the kiss of death for all of them: cf. especially the 802.11n experience with beamforming. Having multiple modes works against the principles of standardization, reduces the chances of any one mode succeeding, and by tying up scarce Task Group resources delays the entire technology. Either merge all spatial reuse functions into a single, unified, *standardized* mode, or delete them all from the draft. Revise – the two modes of SR are distinct because of the difference in implementation complexity required and the varying estimations of the potential gains to be achieved by each of the mechanisms. The group has a long history of including multiple options and variations of a feature within an amendment based on the understanding that no individual has yet been identified who possesses the ability to foretell the future with enough accuracy to allow the one, true, correct, best variation of a feature to be selected while discarding all others, despite the fancy simulation tools and brilliant mathematical analysis that is usually performed to support each proposed variation and prove that it is the one true solution that will bring about world peace or higher throughput or whatever the PAR describes as the mission of this august body. Rather than merge or delete, the proposed resolution of this comment is to provide a more thorough description of the SRP SR mechanism. TGax editor shall incorporate changes in 11-16-1476r19 6844 John Coffey 274.06 "Set to SR Disallowed to disallow SRP-based spatial reuse". Why restrict the disallowing only to SRP-based spatial reuse? The draft would be vastly improved if all spatial Delete Reject – the current sentence reflects the current opinion of the group. The AP of a BSS can disable the use of OBSS_PD based SR within its BSS.
