Abstract: A method and apparatus for decoding a frame control header message in a wireless communication transmission are disclosed. The method comprises assuming at least some of the bits comprising the frame control header message are constant across multiple frames or are known a priori and generating metrics at least from the bits of the frame control header message that are assumed to be constant or are known a priori. The method further comprises decoding the metrics, for example, with a Viterbi decoder or using chase combining, to yield the decode frame control header message.

Abstract: Embodiments of methods and means for auto-correlating wireless signal samples are provided. Such embodiments include local normalization of each signal sample by a root mean square level of samples that preceded it, prior to any summation of the auto-correlation procedure. These auto-correlated signal samples are then used to distinguish downlink from uplink signals present within the signal sample set. Other embodiments include auto-correlation techniques in which no normalization is performed at any time with respect to the summation procedure. Such auto-correlated samples are then scanned to detect a preamble symbol or symbols within the signal samples. Reliable and expeditious wireless communications under WiMAX 802.16e and other protocols can be achieved in accordance with the present embodiments.

Abstract: This disclosure describes methods, apparatus, and systems related to applying channel smoothing to beamformed vectors in wireless communications between a transmitter device and a receiver device. In a first aspect, a device is disclosed that identifies disruptions between at least two first beamforming vectors on adjacent frequencies in a communication channel between the device and a first device of a plurality of user devices. The device determines one or more second beamforming vectors proximate to the identified disruption. The device utilizes the one or more second beamforming vectors to smooth the communication channel between the device and the first device of the plurality of user devices.

Abstract: Described herein is an apparatus having at least two antennas to communicate over multiple communication channels. The apparatus can further include processing circuitry coupled to the at least two antennas to measure isolation in the communication channels while the communication channels are operating in a radar mode to select a channel having highest isolation among the communication channels. The processing circuitry can further perform radar detection over the channel having highest isolation. Other systems and methods are described.

Abstract: Embodiments of an access point (AP) station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN) (i.e., EHT) are generally described herein. In some embodiments, a comb resource unit (RU) structure may be used to distribute tones of an RU across a wider bandwidth for narrow RU power spectral density (PSD) boosting for longer-range transmission in EHT to meet ETSI and/or FCC limitations.
