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.

Claims (52)

1. 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 (STAB), 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.

2. The apparatus of claim 1 , wherein the header portion comprises a sequence of bits, and wherein a bit of the sequence of bits is to have a first value to indicate the SC modulation scheme, and a second value to indicate the OFDM modulation scheme.

3. The apparatus of claim 1 , wherein the EDMG-Header A immediately follows the legacy header.

4. The apparatus of claim 1 , wherein the wireless communication band includes a bonded channel including at least two 2.16 Gigahertz (GHz) channels.

5. The apparatus of claim 4 , wherein the wireless communication band includes the bonded channel including a 4.32 GHz channel consisting of two 2.16 GHz channels.

6. The apparatus of claim 4 , wherein the wireless communication band includes the bonded channel including a 6.48 GHz channel consisting of three 2.16 GHz channels.

7. The apparatus of claim 1 , wherein the non-legacy header includes MU-MIMO parameters including information relating to the SSs.

8. The apparatus of claim 7 , wherein the information relating to the SSs includes information regarding a number of SSs.

9. The apparatus of claim 1 , wherein the non-legacy header includes information relating to training sequences.

10. The apparatus of claim 1 , wherein the EDMG MU PPDU includes:

a Short Training Field (STF);

a Channel Estimation field (CE) following the STF;

a Training (TRN) field following the CE.

11. The apparatus of claim 1 , further including a processor, a radio and one or more directional antennas.

12. The apparatus of claim 11 , further including an input unit and an output unit.

13. 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:

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.

14. The product of claim 13 , wherein the header portion comprises a sequence of bits, and wherein a bit of the sequence of bits is to have a first value to indicate the SC modulation scheme, and a second value to indicate the OFDM modulation scheme.

15. The product of claim 13 , wherein the EDMG-Header A immediately follows the legacy header.

16. The product of claim 13 , wherein the wireless communication band includes a bonded channel including at least two 2.16 Gigahertz (GHz) channels.

17. The product of claim 16 , wherein the wireless communication band includes the bonded channel including a 4.32 GHz channel consisting of two 2.16 GHz channels.

18. The product of claim 16 , wherein the wireless communication band includes the bonded channel including a 6.48 GHz channel consisting of three 2.16 GHz channels.

19. The product of claim 13 , wherein the non-legacy header includes MU-MIMO parameters including information relating to a number of SSs and information relating to training sequences.

20. The product of claim 13 , wherein the EDMG MU PPDU includes:
