doc.: IEEE 802.11-16/0644r0 SS Allocation Discussion Since each STA can only decode its own SS information, SS Allocation in Per User Info field is defined by Starting Spatial Stream (3 bits) and Spatial Stream Number (3 bits) . In broadcast Trigger frame, two options exist for SS allocation: Option 1: SS allocation in Per User Info of broadcast Trigger is same as SS allocation in Per User Info of unicast Trigger. Option 2: SS allocation indicate the spatial stream number (3 bits). We prefer option 1. Submission Slide 12 Liwen Chu, Marvell, et. al.
