Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU). For example, an apparatus may include circuitry and logic configured to cause a wireless station to transmit a first PPDU to a second wireless station, the first PPDU including a preamble, a header, and a first PLCP Service Data Unit (PSDU), the header including a synchronization (sync) indicator to indicate that the second wireless station is to synchronize a second PPDU to the first PPDU; and to receive the second PPDU from the second wireless station, the second PPDU spaced from the first PPDU by less than a Short Inter Frame Space (SIFS), the second PPDU including a Byte Count, and a second PSDU, the second PPDU including no preamble or a short preamble, which is shorter than the preamble of the first PPDU.

Abstract: Exploratory beamforming training techniques for 60 GHz devices are described. In one embodiment, for example, an apparatus may comprise a station (STA) comprising logic, at least a portion of which is in hardware, the logic to identify an exploratory link quality associated with an exploratory beamforming configuration for a directionally-beamformed wireless link, determine whether to revert to a previous beamforming configuration for the directionally-beamformed wireless link based on the exploratory link quality, and in response to a determination to revert to the previous beamforming configuration, send a frame comprising a rollback notification for the directionally-beamformed wireless link. 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.

Abstract: Techniques to enable dynamic bandwidth management at the physical layer level while maintaining backwards compatibility in wireless systems is provided. Furthermore, techniques for reducing the occurrence of exposed nodes are provided. A transmitter may transmit a frame including an indication that a PHY layer sub-header defining a bandwidth associated with a channel is present. Furthermore, the transmitter may transmit a third frame after receiving a second frame from a receiver to indicate to legacy stations that the TXOP was successful.
