    Abstract: Examples are disclosed for providing flexible clear channel assessment (CCA) detection thresholds in a wireless local access network (WLAN). In some examples, an apparatus for dynamically setting a clear channel assessment (CCA) threshold in a wireless local area network (WLAN) may comprise a processor component, a radio coupled to the processor component, and logic for execution by the processor component to establish a CCA threshold for a wireless channel of the WLAN, send a first wireless message to one or more wireless station (STA) devices in wireless proximity to the apparatus informing the one or more STA devices of the established CCA threshold and instructing the one or more STA devices to avoid CCA levels exceeding the CCA threshold on the wireless channel and send a second wireless message to a wireless access point (AP) device associated with the apparatus informing the AP device of the established CCA threshold and instructing the AP device to broadcast use of the CCA threshold on the wireless channel. Other examples are described and claimed.

    Abstract: Embodiments of low-power wake-up packet generation are generally described herein. A wireless device modulates an LP-WUR (low-power wake-up radio) bit sequence with an LP-WUR pulse to obtain a plurality of modulated LP-WUR signals, each modulated LP-WUR signal having a 1× symbol duration. The wireless device multiplexes, in a time domain, an OFDMA (orthogonal frequency division multiple access) signal with a 4× symbol duration with four modulated LP-WUR signals, to generate a multiplexed signal. The wireless device encodes for transmission of the multiplexed signal to a peer device to wake up a WLAN (wireless local area network) radio of the peer device and to another device with an OFDMA signal.

    Abstract: Some new low power architecture devices may, e.g., be associated with in a new device category in the IEEE 802.11ah Standard for devices with low power architecture. Some new low power architecture devices may only to support a subset of modulation and coding schemes (MCSs). Some new low power architecture devices negotiate the use of the subset of MCSs with an access point. Further new low power architecture devices address power consumption through modifications to the architecture of the new low power device. For instance, many new low power architecture devices remove, modify or bypass portions of the front-end transmitter circuitry and/or the front-end receiver circuitry such as a power amplifier, a low noise amplifier, predistortion circuitry, digital-to-analog and analog-to-digital converter resolutions, and stages of filtering.

    Abstract: This document discusses, among other things, apparatus and methods for transmit beamforming sounding. An example method for communicating over a wireless network having multiple sub-carrier frequencies can include assigning a first pilot signal to a first sub-carrier frequency for transmission with a first symbol, transmitting the first symbol from a first wireless device, receiving the first symbol at a second wireless device, determining channel time and phase offset using the first pilot signal, and estimating transmit beamforming channel state information using the first pilot signal.

    Abstract: Embodiments of a wireless station to operate as a per-symbol relay device and method for retransmission of symbols between client devices and a master device using millimeter-wave links is generally disclosed herein. In some embodiments, the relay device may receive one or more of independent symbol streams from the master device. Each independent symbol stream may comprise packets that include groups of one or more symbols. Each group within a packet may be destined for a different one of the client devices. The relay device may separately decode each symbol or group of symbols to generate an independent stream of symbols for retransmission to the client devices using beamforming. The relay device may be arranged to receive, decode, and retransmit each symbol or group of symbols within a delay that is bounded by the number of symbols in the group.

    Abstract: Embodiments of a mobile device transmitter and methods for transmitting signals in different signal dimensions are generally disclosed herein. The mobile device transmitter comprises a mapper to map a block of two or more input modulation symbols to different signal dimensions comprising two or more spatial dimensions, and linear transform circuitry to perform a linear transform on the block of mapped input modulation symbols to generate a block of precoded complex-valued output symbols such that each output symbol carries some information of more than one input modulation symbol. The mobile device also comprises transmitter circuitry to generate time-domain signals from the blocks of precoded complex-valued output symbols for each of the spatial dimensions for transmission using the two or more antennas. The precoded complex-valued output symbols are mapped to different signal dimensions comprising at least different frequency dimensions prior to transmission.
