SIGNALING TECHNIQUES TO SUPPORT DOWNLINK (DL) MULTI-USER MULTIPLE-INPUT MULTIPLE-OUTPUT (MU-MIMO) IN 60 GHZ WIRELESS NETWORKS
First Claim
1. An apparatus, comprising:
- logic, at least a portion of which is in hardware, the logic to decode a physical layer (PHY) header of a physical layer convergence procedure (PLCP) protocol data unit (PPDU) addressed to a plurality of stations (STAs), determine whether the PPDU is addressed to a STA based on the PHY header, and in response to a determination that the PPDU is addressed to the STA, identify one or more spatial streams assigned to the STA based on the PHY header.

Abstract
Signaling techniques to support DL MU-MIMO in 60 GHz wireless networks are described. According to various such techniques, a transmitting 60 GHz-capable device may be configured to include DL MU-MIMO control information in a PHY header of a PPDU that comprises respective data for multiple receiving devices. In some embodiments, the DL MU-MIMO control information may include information identifying each such receiving device. In various embodiments, the DL MU-MIMO control information may include information specifying—for each such receiving device—one or more respective spatial streams that are assigned to that receiving device. Other embodiments are described and claimed.

10. An apparatus, comprising:
-
logic, at least a portion of which is in hardware, the logic to select a plurality of stations (STAs) to which to address a physical layer convergence procedure (PLCP) protocol data unit (PPDU) and address the PPDU to each of the plurality of STAs by including a respective identifier for each of the plurality of STAs in a physical layer (PHY) header of the PPDU; and a radio interface to transmit the PPDU via a plurality of spatial streams, the PHY header to identify a respective assignment of one or more of the plurality of spatial streams to each of the plurality of STAs. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. At least one non-transitory computer-readable storage medium, comprising a set of instructions that, in response to being executed by circuitry of a station (STA), cause the STA to:
-
decode a physical layer (PHY) header of a physical layer convergence procedure (PLCP) protocol data unit (PPDU) addressed to a plurality of STAs; determine whether the PPDU is addressed to the STA based on the PHY header; and in response to a determination that the PPDU is addressed to the STA, identify one or more spatial streams assigned to the STA based on the PHY header. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
