Abstract: Logic may calculate predicted phase rotations based upon more than one previously determined phase rotation. Logic may access memory to store and retrieve previously determined phase rotations to calculate predicted phase rotations. Logic may determine channel information updates such as channel state information and phase correction information from pilot tones that do not travel close to the direct current (DC) tone or the band edge (or guard) tones and replace the missing phase rotations with predicted phase rotations. Logic may skip phase tracking from pilot tones that have traveled close to the DC tone or the edge tones or that experience channel fading, which may result in a predicted phase rotation being more accurate than a phase rotation determined by processing the corresponding pilot tone.

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: Techniques to manage dwell times for pilot rotation are described. An apparatus may comprise a memory configured to store a data structure with a set of modulation and coding schemes (MCS) available to an orthogonal frequency division multiplexing (OFDM) system, each MCS having an associated pilot dwell time. The apparatus may further comprise a processor circuit coupled to the memory, the processor circuit configured to identify a MCS to communicate a packet using multiple subcarriers of the OFDM system, and retrieve a pilot dwell time associated with the MCS from the memory, the pilot dwell time to indicate when to shift a pilot tone between subcarriers of the multiple subcarriers during communication of the packet. Other embodiments are described and claimed.

Abstract: Logic may determine channel information updates such as channel state information and phase correction information from pilot tones that do not travel close to the DC tone or the band edge tones. Logic may skip channel updates and phase tracking from pilot tones that have traveled close to the DC tone or the edge tones. Logic may use channel estimates and phase rotations that are obtained from previous locations of the pilot tones instead of pilot tones that are adjacent to the DC tone or the edge tones. Logic may access memory to store the channel information such as the phase correction information previously obtained and the channel state information previously obtained and derived from processing pilot tones at locations adjacent to the symbol indices next to the DC tone and the edge tones.

Abstract: Examples are disclosed for transmitting data via a relay communication links. In some examples, a wireless device may receive a packet having a physical layer convergence protocol (PLCP) header that indicates whether the packet also includes a relay header placed before a media access controller header. The packet may be dropped or the relay header may be decoded based on a determination of whether the PLCP header indicates that the packet includes the relay header. Other examples are described and claimed.

Abstract: This disclosure describes systems, methods, and devices related to an extreme high throughput (EHT) signaling structure. A device may establish a communication channel with one or more station devices (STAs). The device may generate an extreme high throughput signal field (EHT-SIG) of a header, wherein the EHT-SIG field comprises information associated with resource allocations (RUs). The device may generate a frame comprising the header. The device may assign a first RU to a first station device. The device may assign a second RU to the first station device, wherein the first RU or the second RU is an aggregation of a 26-tome RU and a neighboring RU. The device may cause to send the frame to the first station device.

Abstract: This disclosure describes systems, methods, and devices related to enhanced bandwidth selection for wireless devices. A device may generate a request frame with at least one of a first indication of a bandwidth for which a second device is to measure a first noise level or a second indication of a resource unit for which the second device is to measure a second noise level. The device may send the request frame to the second device. The device may identify a response frame received from the second device, the response frame having a third indication of the first noise level or the second noise level and a fourth indication of the bandwidth or the resource unit. The device may determine, based on the first noise level or the second noise level, a parameter associated with a subsequent frame to send to the second device.

Abstract: Logic may define one or more wake-up preambles suitable for high data rates for a wake-up radio (WUR) packet. Logic may define wake-up preamble with different counts of symbols. Logic may generate a wake-up preamble as two microsecond pulses of orthogonal frequency-division multiplexing (OFDM) symbols in a four megahertz (MHz) bandwidth. Logic may generate and receive a high data rate (HDR) WUR preamble or a low data rate (LDR) WUR preamble. The HDR preamble may signal a data rate of 250 kilobits per second and the LDR preamble may signal a data rate of 62.5 kilobits per second. The HDR preamble bit count may be twice a bit count of the LDR preamble. The HDR preamble may be 32 bits. The duration of transmission of the HDR may be 64 microseconds and duration of transmission of the LDR may be 128 microseconds.
