TECHNIQUES FOR GROUP-BASED SPATIAL STREAM ASSIGNMENT SIGNALING IN 60 GHZ WIRELESS NETWORKS |
摘要 |
Techniques for group-based spatial stream assignment signaling in 60 GHz wireless networks are described. 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 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. Other embodiments are described and claimed. |

1. An apparatus, comprising:
logic, at least a portion of which is in hardware, the logic to determine a group identifier (ID) for a downlink multi-user multiple-input multiple output (DL MU-MIMO) group comprising a station (STA) based on DL MU-MIMO group management information comprised in a received management frame, determine whether a physical layer convergence procedure (PLCP) protocol data unit (PPDU) is addressed to the DL MU-MIMO group comprising the STA based whether a physical layer (PHY) header of the PPDU comprises the group ID for the DL MU-MIMO group comprising the STA, and in response to a determination that the PPDU is addressed to the DL MU-MIMO group comprising the STA, identify one or more spatial streams assigned to the STA based on the PHY header. |
