According to various such techniques, a 60 GHz-capable transmitting device may be configured to define one or more DL MU-MIMO groups, each of which may comprise one or more respective 60 GHz-capable receiving devices. In various embodiments, the 60 GHz-capable transmitting device may include a DL MU-MIMO group ID within DL MU-MIMO control information in a PHY header of a PPDU in order to indicate that the PPDU is directed to a DL MU-MIMO group corresponding to that DL MU-MIMO group ID. In some embodiments, DL MU-MIMO control information may comprise information specifying spatial stream assignments for the 60 GHz-capable receiving devices of that DL MU-MIMO group.

Abstract: This disclosure describes enhanced directional multi gigabit (EDMG) physical layer convergence procedure (PLCP) protocol data unit (PPDU) frames and frame formats for wireless networks. The frame can include a legacy portion and a non-legacy portion. The legacy portion of the frame can be transmitted using a legacy sample (or chip) rate. The non-legacy portion of the frame can be transmitted using a second, different sample (or chip) rate. A transition interval field may be defined between the legacy and the non-legacy portions of the frame, the transition interval field having a predetermined time duration. In one embodiment, the transition interval field can be defined and/or used in connection with one or more standards (for example, a IEEE 802.11ay standard). The various embodiments disclosed herein can be used to facilitate hardware implementation, increase vendor-agnostic compatibility, and allow for accurate, vendor agnostic time-of-flight (ToF) measurements.
