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.

Abstract: A wireless communication device, system and method. The device includes a memory, and processing circuitry coupled to the memory. The processing circuitry includes logic to: determine a training field length associated with a directional multigigabit (DMG) CTS frame of another wireless communication device; determine a Clear-To-Send time (CTS_Time) parameter based at least in part on the training field length; determine a transmit opportunity (TXOP) continuation timeout for the device based on the CTS_Time parameter; and set a network allocation vector (NA V) for the device based on the TXOP con-tinuation timeout.

Abstract: Generally discussed herein are devices and methods for MIMO communications. A device can include processing circuitry (e.g., PHY and/or MAC layer circuitry) configured to transmit an enhanced sector sweep (ESSW) frame for each of a plurality of transmit sectors, wherein each of the plurality of transmit sectors correspond to a weight vector for the first plurality of antennas, each ESSW frame including a plurality of training units to simultaneously beamforming train one or more responder STAs, receive an SSW feedback frame, each SSW feedback frame indicating a transmit sector of the plurality of transmit sectors and a receive sector of a corresponding STA of the one or more STAs to be used in communication between the initiator STA and the responder STA, and transmit one or more SSW acknowledgement frames to the one or more responder STAs to verify the transmit sector and receive sector to use for communication.
