Abstract: A new staggered trigger scheme is described herein to address and optimize deployments using a mix of narrowband (NB) data packets with existing Wi-Fi devices. The approach has the access point (AP) sending staggered wideband trigger frames prepended with a legacy preamble. This signalling method allows frequency multiplexing of low-power NB (LP-NB) devices, in addition to time and frequency multiplexing of both LP-NB and wideband devices in both the downlink (DL) and uplink (UL) direction. Furthermore, the scheme allows for the multiplexing of the new wake-up packets with future narrowband and IEEE 802.11ax data packets. Thus, with this unique staggered trigger frame proposal, LP-NB and wake-up devices unable to transmit or decode the legacy 20 MHz preamble, can share the spectrum with legacy devices with full coexistence provided.

Abstract: Mobile platform power management is an important problem especially for battery-powered small form factor platforms such as smartphones, tablets, wearable devices, Internet of Things (TOT) devices, and the like. A wake-up packet scheduler, a packet manager and a padding manager interact and cooperate to insert at least one wake-up packet on a sub-channel in a padding area after a data frame, the wake-up packet usable by a low-power wake-up radio in, for example, an IEEE 802.11 wireless communication environment.

Abstract: This disclosure describes systems, methods, and devices related to enhanced 60 gigahertz (GHz) preamble. A device may generate a frame for 60 GHz transmission, the frame comprising one or more fields to carry information associated with one or more station devices (STAs). The device may generate a modified legacy signal (L-SIG) field comprising one or more subfields for operation in the 60 GHz transmission. The device may generate a modified legacy long training field (L-LTF) for operation in the 60 GHz transmission. The device may utilize 56 subcarriers in the modified L-LTF in the frame. The device may cause to send the frame comprising the modified L-LTF and the modified L-SIG to the one or more STAs.

Abstract: The devices and methods herein can produce a new waveform for transmission that is robust to carrier frequency offset (CFO) errors, and hence, enables implementation of low cost and low power consumption local oscillators at the Internet of Things (IoT) devices. The proposed method builds upon the existing 802.11ax OFDMA architecture, and adds block filtering to each resource unit to reduce out of band (OOB) emissions. Embodiments also define a modified Universal Filtered OFDM (UF-OFDM) technique that adds a Guard Interval (GI) to UF-OFDM, and thus, provides a GI-UF-OFDM architecture. The added GI helps prevent inter-symbol interference (ISI) at the receiver.

Abstract: Methodologies are presented that provide better uplink and downlink data throughput for cell-edge stations (CE STAs) in wireless networks. In downlink, two or more access points (AP) can work in concert to code a signal such that each AP sends a portion of the data during concurrent transmissions. To further enhance the data throughput of a CE STA, each link between the CE STA and one of the APs can have different characteristics or parameters, for example, a different modulation and coding scheme (MCS). The different characteristics or parameters are communicated to the CE STA through one of various signals sent to the CE STA to allow the CE STA to receive the portions of data over the differently configured links.

Abstract: Today's IEEE 802.11 devices operating in the 2.4/5 GHz bands use a 20 MHz channel as a basic operation unit to maintain coexistence with other 802.11 devices. One exemplary aspect is directed toward using a narrower signal bandwidth (e.g. 2 MHz) in the 2.4/5 GHz bands to reduce transmit/receive power consumption or increase transmission range. However, one problem with introducing a narrow bandwidth signal is how to maintain the coexistence between a legacy IEEE 802.11 device that uses a 20 MHz signal bandwidth and a new IEEE 802.11 device that uses a narrower signal bandwidth.

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: Devices, methods, and media described herein can employ the central 26-tone allocation of 802.11ax for transmission of NB beacons and wake-up packets. Having a dedicated narrowband channel for transmission of NB beacons and/or wake-up packets improves the overall spectrum efficiency. Further, the embodiments may use the central 26-tone subchannel for LP-WUR and legacy IEEE 802.11ax OFDMA transmission, but not for the LP-NB IoT devices that have a OFDM waveform. This configuration reduces the implementation cost and test/certification time & cost of IoT devices.
