    Abstract: This disclosure describes systems, and methods related to determining carrier frequency offset of a wireless communication channel based on a determined phase difference. In some embodiments, an access point is caused to receive one or more streams comprising one or more encoded long training field (LTF) symbols over the wireless communication channel from one or more user devices. The access point then determines a first phase of the wireless communication channel upon receipt of a first LTF symbol, and determines a second phase of the wireless communication channel upon receipt of a second LTF symbol. The access point next determines a phase difference between the first phase and the second phase. Based on the determined phase difference, the access point determines a carrier frequency offset of the wireless communication channel. Lastly, the access point modifies the wireless communication channel based at least in part on the determined CFO.

    Abstract: Embodiments of block acknowledgements request apparatus, systems, and methods are generally described herein. Other embodiments may be described and claimed. An originator operating in a frame-aggregating mode sends a multiple-frame data block to a receiver. The block may include a header for each frame. The header may have an indicator set to indicate a block acknowledgement request. When the multiple-frame block is received with the header of each frame indicating a block acknowledgement request, the receiver may respond with a block acknowledgement for the entire block of frames, without waiting for a separate block acknowledgement request to be sent by the originator following the multiple-frame block.

    Abstract: Methods, apparatus, systems and articles of manufacture to request non-primary wireless channel utilization are disclosed. An example wireless access point device includes memory and processing circuitry configured to: establish connectivity with a narrow-band wireless station on a primary channel, the narrow-band wireless station operating within a bandwidth less than a full-band of the wireless access point device, monitor a non-primary channel within a portion of the full-band to collect monitoring information, transmit the monitoring information about the non-primary channel to the narrow-band wireless station on the primary channel, and in response to acceptance of the non-primary channel by the narrow-band wireless station, establish connectivity with the narrow-band wireless station on the non-primary channel.

    Abstract: Devices and techniques for identification of a station device for spatial frequency reuse are provided. In some embodiments, the identification of the station device can be based on interference information obtained by the station device and sent to a first AP device. The interference information can be indicative or otherwise representative of respective amounts of interference between the station device and each (or, in some embodiments, at least one) of one or more second AP devices. The first AP device can determine the one or more second AP devices, and can send identifying information indicative of the second AP device(s). The first AP device can rely on or otherwise leverage at least the interference information to determine if the AP device can transmit to the station device simultaneously or nearly simultaneously in a defined frequency with downlink transmission(s) from at least one of the second AP device(s).

    Abstract: This disclosure describes systems, methods, and devices related to channelization for 6 GHz band. A device may determine a frequency allocation based on a 6 gigahertz (GHz) band channelization, wherein the 6 GHz channelization includes: one or more frequency allocations associated with one or more bandwidths, wherein the one or more frequency allocations are represented by one or more frequency indices. The device may cause to send a frequency index associated with the frequency allocation to a station device of one or more station devices, wherein the frequency index is based on at least one of the first bandwidth, the second bandwidth, or the third bandwidth.

    Abstract: Embodiments of the disclosure provide auto-detection in wireless telecommunications. Certain embodiments provide or otherwise implement a specific sequence of bits and/or symbols for auto-detection. The specific sequence of bits can be embodied in or can include output codebits from an encoder in a communication device that can send a wireless transmission including the specific sequence. In one embodiment, the encoder can compute or otherwise generate cyclic redundancy checks (CRCs) or other types of validation checks at the communication device. The specific sequence can be determined using the payload of a packet frame. Both the manner in which the specific sequence is generated and the temporal order in which the specific sequence is received relative to other payload in the packet frame can provide specificity to the sequence.
