NOV 2016 doc.: IEEE 802.11-16/1484r1 Introduction Several motions on multi-BF in coping with polarization antenna were approved and the following text was incorporated into SFD [1]: The 11ay beamforming protocol supports multi-beamforming for multiple array antennas. Multi-beamforming means that a transmitter simultaneously sends SSW frames in multiple polarized directions. 11ay provides the means of multi-beamforming capability exchange in which the initiator and responders exchange the information on whether they have the capability of multi- beamforming. This contribution provides details on multi- beamforming through dual-polarization antenna. Submission Slide 2 Kyungtae Jo (LG Electronics)
NOV 2016 doc.: IEEE 802.11-16/1484r1 Recap: Multi-beamforming for 11ay [2] Before entering DTI, Multi-BF capability exchange may be done, in which the initiator and responders exchange the information about BF and MIMO capabilities including Multi-BF capability indication bit . According to the indicators, BF procedure is set up and proceeded through dual-polarized antenna in parallel. Submission 3 Kyungtae Jo (LG Electronics)
NOV 2016 doc.: IEEE 802.11-16/1484r1 Multi-BF with Same Sector through Polarized Antenna Initiator transmits sectors with the same sector ID through dual polarization antenna. Initiator can perform BFs for all responders regardless of the polarization capability of responders. Submission Slide 4 Kyungtae Jo (LG Electronics)
NOV 2016 doc.: IEEE 802.11-16/1484r1 Multi-BF Capability Signaling in EDMG Capabilities element for 11ay The following text is included in SFD [1]: A non-AP or non-PCP EDMG STA declares that it is an EDMG STA by transmitting the EDMG Capabilities element. BF capability can exchange by EDMG Capabilities element for 11ay. EDMG Capabilities element can be composed based on DMG Capabilities element. E.g. Field Bit Description Field Bit Description 0 BF in single-pol. channel is supported. 0 BF in single-pol. channel is supported. PCP/AP Dual- pol. BF Support STA Dual-pol. BF Support 1 BF in dual-pol. channel is supported. 1 BF in dual-pol. channel is supported. Submission Slide 5 Kyungtae Jo (LG Electronics)
NOV 2016 doc.: IEEE 802.11-16/1484r1 Multi-BF Capability Exchange EDMG Capabilities element exchange including Multi- BF capability First, PCP/AP transmits EDMG Capabilities element to STAs. EDMG Capabilities element includes the information whether PCP/AP can support the dual-polarization. The responders transmit EDMG Capabilities element with multi- BF capability of STAs to PCP/AP after they received EDMG Capabilities element with multi-BF capability of PCP/AP. BF procedures between PCP/AP and STAs proceed through dual- polarized antenna allocated by multi-BF capability exchanges. Submission Slide 6 Kyungtae Jo (LG Electronics)
