JAN 2017 doc.: IEEE 802.11-17/0108-00-00ay Introduction The following text was incorporated into SFD : 11ay shall provide means to extend the DMG spatial sharing mechanism for operation in a multi-channel configuration. The Directional Channel Quality Request and Report measurement types shall be modified to support: Request and report for measurements on multiple channels, and Measurements reports averaged over multiple channels The EDMG spatial sharing mechanism shall enable an EDMG STA to perform concurrent measurements employing multiple RX antenna configurations as are used for receiving multiple streams from the target EDMG STA based on the same measurement configuration. The EDMG spatial sharing mechanism shall enable an EDMG STA to report the average of the results of concurrent measurements using multiple RX antenna configurations in order to reduce the overhead of the measurement report. Based on above, this contribution intends to suggest concrete signaling for 11ay spatial sharing. Submission Slide 2 Kyungtae Jo (LG Electronics)
