Related Comments in Subclause 9.4.2.220 5393 Geonjung Ko 93.14 9.4.2.220 When an AP uses the Dual Beacon, a non-AP STA that receives RAPS elements from both Beacon frames of two PPDU formats would initialize its OBO counter twice. Then the STA may have less probability to access the random access RU than a STA that receives one Beacon frame. When an AP uses the Dual Beacon, the RAPS element should be included only in one format of Beacon frame between two formats of Beacon frames. Revised. The Dual Beacon mechanism is deleted.

5391 Geonjung Ko 95.24 9.4.2.222 When an AP uses the Dual Beacon, even if the STA receives any Beacon frame between Beacon frames of two PPDU formats, all STAs in the BSS shall start to use the BSS Color at the same time. e.g. at the TBTT of non-HE format Beacon frame. Need a clarification on a setting of the Color Switch Countdown field. When an AP uses the Dual Beacon, a value of 0 indicates that the switch occurs at the current TBTT if the element is carried in a format Beacon frame or at the next TBTT of a non-HE format Beacon frame if the element is not carried in a nonHE format Beacon frame.

Related Comments in Subclause 11.1.3.10 3055 Abhishek Patil 141.00 11.1.3.10 Only HE STAs can understand an HE Beacon in Extended PPDU format. Such beacon need not carry information that is relevant to non-HE/legacy STAs. This will help reduce the size of HE Beacon. Add a sentence which implies that an HE beacon may not include fields/IEs that apply only to legacy STAs. Revised. The Dual Beacon mechanism is deleted.
