Abstract: For example, an apparatus may be configured to cause an Access Point (AP) Multi-Link Device (MLD) to, during an ongoing communication between a first AP of the AP MLD and a first non-AP wireless communication station (STA) over a first wireless communication channel, communicate a suspend request by a second AP of the AP MLD over a second wireless communication channel, the suspend request configured to request suspension of the ongoing communication between the first AP of the AP MLD and the first non-AP STA; to suspend the ongoing communication between the first AP of the MLD and the first non-AP STA over the first wireless communication channel for a suspension period; and to communicate a frame by the first AP over the first wireless communication channel during the suspension period, the frame communicated between the first AP and a second non-AP STA.

Abstract: Methods and systems herein provide better downlink (DL) data throughput for cell-edge stations (CE STAs). The systems enable protection from a third-party collision during a wideband DL data transmission to the cell edge STA, when the wideband control frame, such as clear-to-send (CTS) or acknowledge (ACK), transmission from a cell edge STA cannot reach the AP. This process can be achieved by designing a new wideband control frame comprising: a legacy preamble sent over the primary 20 MHz channel that can be decoded by the legacy STAs, a new preamble sent over the primary 20 MHz channel that can be used to identify the new wideband control frame (this new preamble has the total signal bandwidth information for the rest of the packet following the new preamble); and duplicate legacy control packets set over the total bandwidth indicated in the new preamble (the legacy control packets can be decoded by the legacy STAs).

Abstract: Logic may comprise hardware and/or code to select a narrow band from a wider channel bandwidth. Logic of communications between devices may select, e.g., a 1 or 2 MHz sub-channel from a wider channel bandwidth such as 4, 8, and 16 MHz and transmit packets on the selected 1 or 2 MHz channel. For instance, a first device may comprise an access point and a second device may comprise a station such as a low power sensor or a meter that may, e.g., operate on battery power. Logic of the devices may facilitate a frequency selective transmission scheme. Logic of the access point may transmit sounding packets or control frames across the sub-channels of the wide bandwidth channel, facilitating selection by the stations of a sub-channel and subsequent communications on the sub-channel between the access point and the station.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of a wakeup packet response. For example, an apparatus may include circuitry configured to cause a first wireless device to transmit a frame comprising mapping information to map a plurality of Modulation and Coding Schemes (MCS) to a respective plurality of preamble lengths; generate a wakeup packet comprising a preamble having a preamble length of the plurality of preamble lengths corresponding to an MCS of a non-wakeup transmission from the first wireless device; and transmit the wakeup packet to a second wireless device.

Abstract: Embodiments may implement a new hierarchical data structure for traffic indication mapping to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames with a partial virtual bitmap based upon the hierarchical data structure for traffic indication mapping. In some embodiments, the MAC sublayer logic may store the traffic indication map and/or the traffic indication map structure in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive, detect, and decode communications with frames comprising the partial virtual bitmap based upon the hierarchical data structure. In some embodiments, indications of buffered data for pages, super-blocks, blocks, sub-blocks, and/or stations may be inverted. In several embodiments, a new association identifier (AID) structure is defined for the new hierarchical data structure for traffic indication mapping.

Abstract: Techniques have been proposed to transmit a wake-up packet at the central 26-tone resource unit of the IEEE 802.11ax OFDMA structure with a low-power wake-up radio packet within the OFDMA allocation. Prior techniques proposed to multiplex transmission of the wake-up packet with IEEE 802.11ax OFDMA PPDUs; leaving the RUs adjacent to the central 26-tone unassigned to function as guard bands. These guard bands are needed to reduce the impact of the adjacent channel interference on the LP-WUR. One embodiment transmits the 26×20 MHz/256=2.03125 MHz wake-up pulse at the center of (or in general anywhere within) the band (e.g., RU5) without requiring the nulling of the seven DC subcarriers. This moves the wakeup pulse inward leaving larger guard bands between the wake-up packet and the adjacent OFDMA allocations. This at least improves the LP-WUR detection performance and will allow assignment of more RUs to IEEE 802.11ax OFDMA PPDUs—Thereby improving overall system throughput and efficiency.

Abstract: A wireless device, system and method. The device includes a processing circuitry is configured to decode duplicate Request to Send (RTS) frames from a first access point (AP) that is part of an Extended Service Set (ESS) including a second AP, the first AP and the second AP buffering data for the device. The processing circuitry is further to cause transmission of duplicate multi-AP channel bonding (MACB) Trigger frames to the first AP and to the second AP in response to the duplicate RTS frames. Each of the duplicate RTS frames and duplicate Trigger frames have a legacy preamble portion over a first bandwidth of a corresponding wireless channel, and a MACB portion over a second narrower bandwidth of the corresponding wireless channel. The processing circuitry is further to decode a first data frame portion from the first AP and a second data frame portion from the second AP.

Abstract: Examples are disclosed for multi-level service discovery. In some examples, a first level of information indicating a service type for a service provided by a first wireless device may be transmitted by the first wireless device to another wireless device. The first level may enable the other wireless device to determine whether the indicated service type at least partially matches a service interest. A second level may then be transmitted by the first wireless device that includes a service identification to enable the other wireless device to determine whether the service substantially matches a service interest for the other wireless device. A third level may then be transmitted from the first wireless device that includes service content information. The third level may be transmitted responsive to the other wireless device requesting the service content information. Other examples are described and claimed.

Abstract: Various embodiments are generally directed to an apparatus, method and other techniques for performing neighbor awareness network (NAN) discovery operations to discover a NAN cluster comprising one or more devices synchronized to a discovery window. In some embodiments, the NAN discovery operation may include communicating a cluster discovery message to join the NAN cluster, waiting a first time period for a response to the cluster discovery message, and joining the NAN cluster based on information in the response to synchronize to the discovery window when the response is received within the first time period. Various embodiments may also include disabling, by the processing circuitry, one or more operations to perform the NAN discovery operations if the response is not received within the first time period.

Abstract: Described herein are various wake-up procedures for user equipments (UEs). A UE may include a low power wake-up radio (LP-WUR) separate from a front end module (FEM). The LP-WUR may remain awake continuously (or at high-frequency intervals) and monitor for a wakeup signal, allowing the FEM to remain powered down in the absence of downlink data. When the LP-WUR detects a wakeup signal configured for the LP-WUR, the LP-WUR may be configured to wake up the FEM to receive incoming downlink data. Various network components may be configured to ensure UEs with LP-WURs receive corresponding wake-up signals.
