Abstract: Methods, apparatuses, and computer readable media for MU-RTS and CTS are disclosed. An apparatus of a high-efficiency wireless local-area network (HEW) master station is disclosed. The HEW master station including processing circuitry configured to generate a packet to indicate a multi-user request-to-send (MU-RTS) and to indicate channels on which one or more HEW stations are to transmit a clear-to-send (CTS). The HEW master station further including a transceiver configured to transmit the packet to the one or more HEW stations, and receive clear-to-send responses to the packet on the one or more channels. An apparatus of a HEW station is also disclosed. The HEW station including circuitry configured to receive a packet that indicates a MU-RTS that indicates channels on which the HEW station is to transmit a CTS, and to determine whether to send the CTS.

Abstract: A method for transmit time offset in a UL-MU-MIMO system monitors respective transmit powers, over a wireless channel, for a plurality of stations in the system. A respective transmit time offset is determined for each station in response to the respective transmit power of each station. A poll exchange sequence is initiated in which the transmit time offsets are transmitted to each respective station. An access point can then receive data from the stations at times adjusted by the respective transmit time offsets.

Abstract: A wireless communication device comprises a transceiver configured to communicate information with one or more neighbor devices in accordance with a sync mode of a WiFi communication protocol, and a controller. The controller is configured to monitor for reception of at least one of a response frame or a beacon frame sent by any neighbor device, determine whether to schedule transmission of a service frame, and change operation to a background scan mode when the at least one of the response frame or the beacon frame sent by any neighbor device is undetected for a specified time duration and the transmission of a service frame is unscheduled.

Abstract: Disclosed in some examples are methods, systems, and machine readable mediums which allow for wireless devices with limited echo cancellation capabilities to participate in full-duplex communications. In some examples, by carefully controlling transmission powers and the modulation and coding schemes (MCS) used in the transmissions, both devices can engage in full-duplex communication.
