Abstract

This disclosure describes systems, methods, and devices related to channel access flow for wireless communication. A device may establish a multiuser multiple input and multiple output (MU-MIMO) transmission opportunity by determining a DMG clear to send-to-self frame or a Grant frame, determining a control trailer, and sending a DMG clear to send-to-self frame with a control trailer appended thereto or a Grant frame with a control trailer appended thereto to a group of intended MU-MIMO transmission recipients. The recipients may receive one or more frames of the subsequent MU-MIMO transmission.
