Abstract
Some demonstrative embodiments include apparatuses, devices, systems and methods of multi-user (MU) wireless communication. For example, a wireless station may generate a MU Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU) including a header field and a plurality of Spatial Streams (SSs) of Media Access Control (MAC) Protocol Data Units (MPDUs) to a plurality of users, the header field including an indication of a plurality of modulation schemes corresponding to respective ones of the plurality of users; and process transmission of the MU PPDU to the plurality of users over a wireless communication band.

An apparatus comprising memory circuitry, and one or more processors, the one or more processors to:
- generate an Extended Directional Multigigabit (EDMG) Multi-User (MU) Physical Layer Convergence Protocol Data Unit (PPDU) for a MU transmission, the PPDU comprising a header portion and a data portion, the data portion including a plurality of Media Access Control (MAC) Protocol Data Units (MPDUs) in a plurality of Spatial Streams (SSs) and addressed to a plurality of wireless stations (STAs), wherein:
- the header portion indicates a modulation scheme for the MU transmission, the modulation scheme including a Single Carrier (SC) modulation scheme or an Orthogonal Frequency Division Multiplexing (OFDM) modulation scheme;
- the header portion includes a legacy header, and a non-legacy header following the legacy header, the non-legacy header including a first non-legacy header EDMG-Header A, and a second non-legacy header EDMG-Header B, the EDMG-Header B indicating a plurality of Modulation and Coding Schemes (MCSs) on a per SS basis;
- modulate the SSs according to the modulation scheme and to the MCSs;
- and
- cause transmission of the EDMG MU PPDU to the plurality of users over a wireless communication band.
A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one computer processor, cause a wireless station to:
