Abstract:
Techniques for packet-loss handling for downlink Multi-User Multiple-input and Multiple-Output (DL MU-MIMO) wireless networking environment are described herein. The techniques described herein help define how a wireless access point should behave when faced with a packet-loss situation of a DL transmission burst in a MU-MIMO wireless network.
Abstract:
Embodiments of a wireless device and methods for rekeying with reduced packet loss in a wireless network are generally described herein. In some embodiments, during rekeying operations a new key for reception may be installed early (i.e., prior to receipt of a rekeying confirmation message). The use of the new key for transmission may be delayed until after receipt of the rekeying confirmation message. The early installation of the new key for reception may allow both the new key and old key to be active at the same time for use decrypting received packets to reduce packet loss during rekeying operations. The rekeying confirmation message may be the fourth message of a four-way handshake for rekeying. In some embodiments, two key identifiers may be alternated between four- way handshakes to prevent deletion of the old key.
Abstract:
Some demonstrative embodiments include devices, systems and/or methods of scheduling communications with a group of wireless communication devices. For example, a wireless communication unit may transmit at least one scheduling frame including an indication of a downlink period allocated for simultaneous transmission from the wireless communication unit to at least one group of a plurality of wireless communication devices, wherein the wireless communication unit is to simultaneously transmit a plurality of different wireless communication transmissions to the plurality of wireless communication devices of the group during the downlink period. Other embodiments are described and claimed.

Some demonstrative embodiments include devices, systems and/or methods of simultaneously communicating with a group of wireless communication devices. For example, a device may include a wireless communication unit to communicate with at least one group of a plurality of wireless communication devices over a wireless communication medium, wherein the wireless communication unit is to reserve the wireless communication medium for a time period, during which the wireless communication unit is to simultaneously transmit two or more different wireless communication transmissions to two or more wireless communication devices of the group, respectively. Other embodiments are described and claimed.
Abstract:
An apparatus of a wireless station (STA) comprises: memory and processing circuitry coupled to the memory. The processing circuity is configured to: encode a management frame including a wake-up radio (WUR) mode element that indicates a default WUR mode state of the STA, wherein the default WUR mode state determines a response of the STA to a wake-up packet; configure the STA to transmit the management frame to one or more wireless devices; enter a power mode in which the STA communicates with the one or more devices using a power save communication protocol; and communicate data, in response to decoding the wake-up packet, with the one or more wireless devices using a signaling protocol determined by the indicated default WUR mode state and the power save communication protocol.
Abstract:
Methods, apparatuses, and computer-readable medium are described for supporting an opportunistic power save mode. An awake state of a station is determined by an access point. The number of unicast and multicast frames that will be transmitted to the station in a current service period is determined. A bit within a bitmap corresponding to the association identifier of the station is determined and set based upon the awake state of the station and the number of frames that will be transmitted to the station. The bitmap is encoded for transmission. The station uses its corresponding bit to determine if the station may enter a doze state.
Abstract:
Wireless devices, methods, and computer readable media for synchronization in a wireless local-area network. A method on a wireless communication device may include tuning to a first subchannel based on a schedule received from an access point (AP) the schedule to indicate that the HEW device is assigned to the first subchannel. The method may further include determining a target beacon receive time and tuning to a second subchannel to receive the target beacon at the target beacon receive time. The method may further include receiving the target beacon on the second subchannel and tuning back to the first subchannel. A method on an AP for synchronization may include transmitting information that indicates a target beacon receive time on a subchannel. The method may include not transmitting to a wireless communication device operating on a second subchannel for a period of time before the target beacon receive time, and transmitting a target beacon on a first subchannel at the target beacon receive time.

For example, a device may include a wireless communication unit to transmit at least one beamforming-training initiation frame to a group of a plurality of wireless communication devices, wherein the wireless communication unit is to receive two or more feedback frames from two or more of the wireless communication devices, wherein the wireless communication unit is to determine two or more beamforming schemes based on the two or more feedback frames, and wherein the wireless communication unit is to simultaneously transmit two or more different wireless communication transmissions to the two or more wireless communication devices, respectively, using the two or more beamforming schemes, respectively. Other embodiments are described and claimed.
Abstract:
Methods, apparatus, and computer-readable media are described for enabling six gigahertz operation based on geolocation precision. A geographic location and an imprecision of the geographic location of an AP are determined. The geographic location and the imprecision are encoded for transmission to a remote entity. In response to the transmission of the geographic location and the imprecision, operating restrictions for the 6GHz band are received. Based on the operating restrictions, interference from the AP on an incumbent system is calculated. An available channel within the 6GHz band based on the calculated interference is determined. Data is encoded for transmission on the available channel.
