Abstract: An example method for selectively filtering Wi-Fi signals is presented. A first radio and a second radio of a wireless networking device (WND) are respectively operated on a first channel and a second channel. The first channel and the second channel are respectively within a first sub-band of a first frequency band and second sub-band of a second frequency band. A control unit of the WND may select one of a first filter or a second filter based on the first channel, and one of a third filter or a fourth filter based on the second channel. After the filters are selected, signals over the first channel are communicated through a selected one of the first filter or the second filter, and signals over the second channel are communicated through a selected one of the third filter or the fourth filter.

Abstract: Systems and methods are provided by which all APs in a particular deployment can be used to assist in the out-of-band discovery of 6 GHz radios by client devices. That is, a series of iterative operations can be performed to: (I) determine the state of 6 GHz radios in a zone/deployment area; (II) identify what radios can be considered near-neighbors to non-6 GHz radios for purposes of advertising one or more of the 6 GHz radios; (Ill) rank neighboring 6 GHz radios for a given non-6 GHz radio based on certain radio metrics; and (IV) ultimately determine those 6 GHz radios that can be advertised by the given non-6 GHz radio.

Abstract: Systems and methods are provided for optimizing the scheduling of Orthogonal Frequency-Division Multiple Access (OFDMA) transmissions in the downlink (DL) direction. A two-stage mechanism can be implemented when effectuating DL OFDMA transmission involving multiple modulation and coding schemes (MCS) in a single transmit burst. A first stage of the two-stage mechanism may use radio frequency (RF) boosting/de-boosting of Resource Units (RUs) such that the average input power to an AP power amplifier (PA) may remain under a saturated PA output power to ensure PA linearity. If RF boosting/de-boosting is not supported, an alternative mechanism for OFDMA grouping (to rigid grouping) can be employed to skip higher MCS.

Abstract: Examples described herein provide selective filtering by a network device for continuous 5 GHz and 6 GHz operation. Examples may include receiving, by the network device, a first signal in a 5 GHz band, and generating, by the network device, a second signal in a 6 GHz band. Examples may include selecting, by the network device, a first filter or a second filter to be applied the first signal in the 5 GHz band, wherein the first filter allows a lower frequency band to pass than the second filter in the 5 GHz band, selecting, by the network device, a third filter or a fourth filter to be applied to the second signal in the 6 GHz band, wherein the third filter allows a lower frequency band to pass than the fourth filter in the 6 GHz band, and simultaneously applying, by the network device, the selected first or second filter to the first signal and the selected third or fourth filter to the second signal.

Abstract: Systems and techniques are described that are directed to filter frequency response shift compensation, including compensating for shifting in the rejection band of the filter. Compensation for the shifting in the rejection band can include applying a pre-distortion to attenuate edge resource units (RUs), and applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme reduce bandwidth in the channel, thereby dropping the out of band RUs. Front ends provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front ends can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio. The radio can then apply a digital pre-distortion to compensate for the shifting in the rejection band.

Abstract: One embodiment can provide a method and a system for performing multiple radio frequency allocation. During operation, the system including a controller can receive, a Wi-Fi channel allocation and a filter bank configuration associated with a Wi-Fi radio transceiver. The system can determine one or more Internet of things (IoT) radio transceivers operating with the Wi-Fi radio transceiver. For a respective IoT radio transceiver, the system can perform the following operations: determining a set of scores based on a set of constraints associated with an application type for the IoT radio transceiver; and computing a weighted average score based on the set of scores; and determining a channel allocation for the IoT radio transceiver based on the weighted average score and the Wi-Fi channel allocation.

Abstract: A non-transitory computer-readable medium, network device, and method for enabling simultaneous transmit and receive in the same Wi-Fi band within a device by obtaining a first information corresponding to a first set of signals to be transmitted wirelessly by a first antenna of a first device; transmitting, by the first antenna of the first device, the first set of signals; receiving, by a second antenna of the first device, a second set of signals comprising (a) the first set of signals transmitted by the first antenna of the first device and (b) a third set of signals transmitted by a second device different than the first device; determining a third information corresponding to the third set of signals by canceling the first set of signals from the second set of signals, wherein the third information comprises an estimation of the third set of signals transmitted by the second device.

Abstract: Systems and techniques are described that are directed to filter frequency response shift compensation, including attenuation compensation. Attenuation compensation can apply a pre-distortion to compensate for the magnitude of attenuated resource units (RUs). Additionally, filter frequency response shift can involve applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme can reduce bandwidth in the channel, thereby dropping the affected RUs. The attenuation compensation is implemented using front ends that provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front end can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio. The radio then applying a digital pre-distortion to a signal input into the one or more filters to compensate for the attenuated RUs.
