July 2018 doc.: IEEE 802.11-18/2089r2 Abstract Resolution of CIDs 3297, 3361, 3480, 3658, and 3688 is presented. Submission Slide 2 Solomon Trainin, Qualcomm
July 2018 doc.: IEEE 802.11-18/2089r2 Beaconing role Make known of the presence of the network Network Management: Scan, Neighbor report DMG beamforming BTI, A-BFT, ATI/DTI Submission Slide 3 Solomon Trainin, Qualcomm
July 2018 doc.: IEEE 802.11-18/2089r2 Proposal DMG Beacon format The beacon PPDU contains RX TRN s The TDD slot structure and the TDD slot schedule elements are optionally presented in the beacon Presence of the Extended schedule element is mandatory New IE DMG STA Tx Power and Rx Sensitivity parameters element is introduced to be conveyed in the DMG Beacon Submission Slide 4 Solomon Trainin, Qualcomm
July 2018 doc.: IEEE 802.11-18/2089r2 Proposal (continuation) Alternative beaconing procedure One DMG beacon frame is transmitted per each Tx antenna configuration that is established to communicate with the associated STA Submission Slide 5 Solomon Trainin, Qualcomm

July 2018 doc.: IEEE 802.11-18/2089r2 HOW TRP, G_ADD_SENS and TRN field may be used When a STA receives a beacon from the AP, its measured receive power is ??? When the AP receives a PPDU from this STA, using the same antenna configuration ??? Substituting ??? pattern reciprocity) We have that the STA should maintain P to make sure it doesn t create interference at the AP. (Note that All the elements on the right-hand side are known to the STA) ???= ?????+ ??? ???? ??? ???????? + ??? ???? ???????? + ??? ??? ????? ??? ??= ??????+ ??? ??? ???????? = ??? ??? ???? (Assuming AP antenna ???? + ??? ??? ?????+ ??? ???? min_sensitivity ??????+ ??? ??? AP TX antenna gain in direction ? - direction to the STA ??? ??? AP RX antenna gain in direction ? ??? ???(?) STA TX antenna gain in direction ? direction to the AP the STA may estimate ? based on TRN field appended to the PPDU ??? ???(?)- STA RX antenna gain in direction ? ????? Total Radiated Power at the AP (published in the SSW field) ??? ?????? Total Radiated Power at the STA know to the STA. Submission Slide 7 Solomon Trainin, Qualcomm
July 2018 doc.: IEEE 802.11-18/2089r2 HOW TRP, G_ADD_SENS and TRN field may be used cont. For example, if the TRP is 10dBm, and the STA receives the beacon at - -54dBm. If the STA transmits at 10dBm (TRPSTA) and the STA and the AP have antenna reciprocity, the AP receives at -54dBm In order for the STA to cause interference at the AP with receive power less that -78dBm, it needs to either reduce the TRP, or use an antenna pattern that has lower gain in the direction of the AP.
