16886 802.19 comment from Alaa Mourad: Add consideration of 802.15.4 HRP UWB and LRP UWB PHYs which both include channel definitions operating in 6 GHz band. Coexistence has not been characterized or analyzed with respect to impulse modulations in the same band. Rejected This is not a comment on the draft amendment, however with respect to the CA document: The IEEE 802 LMSC OPERATIONS MANUAL states as follows "The CA document shall address coexistence with all relevant approved IEEE 802 LMSC wireless standards specifying devices for unlicensed operation. The WG should consider other specifications in their identified target band(s) in the CA document." 802.11 coexistence with non-802.11 systems is addressed in Section 3 of the CA document. There is no LMSC requirement for analysis or simulation or testing. CA document has been amended to acknowledge UWB with the relevant regulations. Refer to 16887 802.19 comment from Benjamin Rolfe: In general, the CAD assumes that the coexistence characteristics of 802.11ax are "just like" legacy 802.11 OFDM, addressing only where new features would differ, which seemed reasonable. However with the expansion of channel plans into bands previously not specified, the 'just like' assumption is no longer true. There are other 802 services in the bands covered by the expanded scope which need to be considered and are not. Expand the analysis to include specifically coexistence between 802.11ax and 802.15.4 UWB systems operating in the bands above 6 GHz. Rejected This is not a comment on the draft amendment, however with respect to the CA document: The IEEE 802 LMSC OPERATIONS MANUAL states as follows "The CA document shall address coexistence with all relevant approved IEEE 802 LMSC wireless standards specifying devices for unlicensed operation.
