Apparatus, system and method of transmitting a PPDU

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 processor, enable the at least one processor to cause an Enhanced Directional Multi-Gigabit (DMG) (EDMG) wireless communication station (STA) to generate a transmission of an EDMG Orthogonal Frequency Division Multiplexing (OFDM) Multi User (MU) Physical Layer (PHY) Protocol Data Unit (PPDU) for a plurality of users, wherein the instructions, when executed, cause the EDMG STA to:

• generate a plurality of space-time stream flows corresponding to the plurality of users, respectively, a space-time stream flow corresponding to a user comprising one or more space-time streams corresponding to the user, wherein generating the plurality of space-time stream flows corresponding to the plurality of users comprises encoding the EDMG OFDM MU PPDU with an independent flow per user, and maintaining a common space-time stream numeration over all users of the plurality of users, wherein generating the plurality of space-time stream flows corresponding to the plurality of users comprises:
• building symbols of an EDMG Short Training Field (EDMG-STF) and an EDMG Channel Estimation Field (EDMG-CEF) of the space-time stream flow corresponding to the user;
• generating scrambled bits of the space-time stream flow corresponding to the user by scrambling bits of a data field for the user;
• encoding the scrambled bits of the space-time stream flow corresponding to the user into encoded bits of the space-time stream flow corresponding to the user according to a Low-Density Parity-Check (LDPC) code;
• and
• mapping the encoded bits of the space-time stream flow corresponding to the user into constellation points over one or more spatial streams of the space-time stream flow corresponding to the user;
• and
• map the plurality of space-time stream flows corresponding to the plurality of users to a plurality of transmit chains, wherein the one or more space-time streams corresponding to the user are based on the symbols of the EDMG-STF and EDMG-CEF of the space-time stream flow corresponding to the user, and on the constellation points over the one or more spatial streams of the space-time stream flow corresponding to the user.
