IEEE P802.11 Wireless LANs Resolutions for Comments related to Extended Range Beacon 2017-04-06 Date: 1, Komukai +81 44 549 Tomoko Adachi Toshiba Saiwai-ku, tomo.adachi@toshiba.co.jp 2283 Kawasaki, Japan Narendar Toshiba Madhavan Newracom Yongho Seok Intel Po-Kai Robert Stacey Intel Revision Notes r1: changed 17/XXXX in resolution column to show this document number. r2: changed resolution that says to Added resolutions for CIDs 5165, 5905, 6554, “Approve” “Accept”. 6560, 7977, 9561, and 9868 and updated the number of CIDs in the abstract. Discussion HE ER SU PPDU Beacon The baseline spec has the following: Rate selection for non-STBC Beacon and non-STBC PSMP frames “10.7.5.1 If the BSSBasicRateSet parameter is not a non-STBC PSMP frame or a non-STBC Beacon frame shall be transmitted in a non-HT PPDU using one of the rates included in the BSSBasicRateSet parameter. If the BSSBasicRateSet parameter is empty, the frame shall be transmitted in a non-HT PPDU using one of the mandatory PHY rates.” With this, up to now, a Beacon other than sent in STBC is always sent in non-HT PPDU for operation in the legacy band. Based on this basic rule, we can assume that all the STAs associated with the AP are within the coverage of non-HT PPDU frames from the AP. As all the STAs other than only supporting DSSS can receive and decode the non-HT PPDU, which means the STAs can set NAV by frames transmitted in non-HT PPDU, the AP can use non-HT PPDU to achieve robust protection.
