Abstract: In single user OFDM wireless communication, the serial bit stream in a Medium access control Protocol Data Unit (MPDU) to be transmitted may be split up and routed in parallel through different encoding modules. In one embodiment the entire bit stream may be processed through an LDPC, and the output of the LDPC module split up before being routed to different Modulation Modules that each select a separate MCS for the associated sub-band. In another embodiment the bit stream may be split up before being processed separately through multiple LDPC modules, and the output of each LDPC module may then be routed to a different associated Modulation Module for selection of a separate MCS for the associated sub-band.

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.

Abstract: Devices and methods of limiting wideband STA communication are generally described. The STA receives, over a primary channel, a wakeup frame containing an indication of a SP or CBAP to acquire a wideband TXOP over a wide bandwidth channel including the primary channel and a secondary channel and a control trailer having an indication of the wide bandwidth channel. Prior to the SP/CBAP, the STA opens reception from the primary channel to the wide bandwidth channel. The STA then communicates with another STA over the wide bandwidth channel and subsequently reduces reception from the wide bandwidth channel to the primary channel. The wakeup frame originates from an AP/PCP or the other STA, and contains fields indicating the wakeup frame length and SP or a sensing time length prior to the CBAP.

Abstract: Embodiments of a station (STA) and method for communication on primary and secondary channel resources are generally described herein. The STA may transmit a grant frame to indicate a transmission of a data payload by the STA during a grant period. The grant frame may indicate whether the data payload is to be transmitted on primary channel resources or on secondary channel resources. The STA may transmit the data payload to a destination STA on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources. The grant frame may be transmitted on the primary channel resources and on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources.
