    Abstract: This disclosure describes systems, methods, and computer-readable media related to phishing and brand protection via copycat detection. In some embodiments, a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbol durations may be determined. A plurality of data streams may be generated by executing a plurality of sliding window operations using a respective shifting window for each of the plurality of OFDM symbol durations. Each of the plurality of data streams may be dissected into a respective plurality of segments using a total number of cyclic prefix (CP) lengths associated with the respective shifting window, wherein each segment of the respective plurality of segments is a vector. A plurality of vector sums corresponding to each of the plurality of data streams may be determined. A Wi-Fi signal may be detected when one of the plurality of vector sums exceeds a threshold.

    Abstract: Embodiments of the present disclosure describe systems and methods for precoding wireless transmissions. Various embodiments may precode rank-one or rank-two wireless transmissions onto four antennas. Various embodiments may precode wireless transmissions using a precoding matrix selected from a group of matrices, wherein different groups of matrices differ in total angular region, number of beams, or angular distance between beams. Other embodiments may be described and/or claimed.

    Abstract: This disclosure describes methods, apparatus, and systems related to an OFDMA uplink resource allocation framework. An access point may determine a first trigger frame including one or more resource block identifications (RBIDs) associated with one or more resource units on a communication channel. The access point may assign at least one of the one or more RBIDs to at least one device of one or more devices. The access point may cause to send the first trigger frame to the least one device The access point may identify a resource request frame including at least in part a resource request indication associated with the at least one of the one or more RBIDs The access point may assign one of the one or more resource units based at least in part on the resource request indication.

    Abstract: This disclosure describes methods, apparatus, and systems related to a high efficiency signal field encoding structure. A device may determine a communications channel having a bandwidth of a frequency band. The device may determine a first group of subchannels of the bandwidth and a second group of subchannels of the bandwidth. The device may determine a high-efficiency signal field to be transmitted on the communications channel to a first device. The device may encode the high-efficiency signal field using the first group of subchannels and the second group of subchannels. The device may cause to send the high-efficiency signal field to the first device.

    Abstract: Technology for decreasing latency for contention based scheduling request (SR) is disclosed. A user equipment (UE) can randomly select a physical random access channel (PRACH) preamble index for a PRACH transmission. The UE can multiplex the PRACH preamble index together with a SR message containing a cell radio network temporary identifier (C-RNTI) and a buffer status report (BSR) for the PRACH transmission. The UE can process, for transmission, to an enhanced node B (eNB), the PRACH preamble index multiplexed with the SR message in a subframe #(n) of the PRACH transmission, wherein n is a subframe number.
