Abstract: Improving backscattering and, specifically, a physical Layer transmit mode for improving the Signal-to-Interference Ratio (SIR) of backscatter signals may be provided. A transmitter may determine a Backscatter Device (BKD) to send a transmission to for backscattering. The transmitter may determine a width of a puncture in the transmission. Next, the transmitter may transmit the transmission to the BKD. The transmitter may receive feedback from a receiver about decoding a backscattered signal generated using the transmission. The transmitter may adjust the width of the puncture for a subsequent transmission based on the feedback.

Abstract: Crest Factor Reduction (CFR) parameters are determined for a dual band Power Amplifier (PA). A first band of the dual band PA is associated with a first Multi-Link Operation (MLO) link and a second band of the dual band PA is associated with a second MLO link. Determining the CFR parameters comprises determining based on a configuration of the first MLO link and the second MLO link. A first portion of the CFR parameters is provided to a first crest factor reduction block. First portion of the CFR parameters comprises a first clipping threshold associated with the first band and first filter coefficients associated with the first band. A second portion of the CFR parameters is provided to a second crest factor reduction block. The second portion of the CFR parameters comprises a second clipping threshold associated with the second band and second filter coefficients associated with the second band.

Abstract: A method may be provided. One or more packets from a client may be received, in a block based modulation environment, at one or more switchable antennas of an access point. The access point may have a plurality of switchable antennas. Each switchable antenna may have an antenna state. The plurality of switchable antennas may be switched among such that at least five of the antenna states are sampled. Angle of arrival of the client may be calculated based on the at least five of the antenna states.

Abstract: Techniques for distributed computation are provided. A plurality of edge computing devices available to execute a computing task for a client device is identified, and a first latency of transmitting data among the plurality of edge computing devices is determined. A second latency of transmitting data from the client device to the plurality of edge computing devices is determined, and a set of edge computing devices, from the plurality of edge computing devices, is determined to execute the computing task based at least in part on the first and second latencies. Execution of the computing task is facilitated using the set of edge computing devices, where the client device transmits a portion of the computing task directly to each edge computing device of the set of edge computing devices.

Abstract: Optimal determination of transmit power level for MLDs in A Wireless Local Area Network (WLAN). An AP can establish synchronous downlink multi-link operations with another MLD. A first link and a second link between the AP and the MLD both operate in a same sub-band. The AP can then determine the same power level for both the first link and second link. After establishing the same power level, the AP can then determine a second power level for the first link and a third power level for the second link. The second power level is greater than the third power level. The AP can then provide the second power level for the first link and the third power level for the second link.

Abstract: Optimal determination of a Wireless Local Area Network (WLAN) sounding method and system may be provided. An Access Point (AP) selects a subchannel for the partial sounding. The AP then sounds the selected subchannel. A client station responds with Channel State Information (CSI). The AP can receive the CSI, from the client station, in response to the sounding. Based on the CSI from the selected subchannel, the AP extrapolates the CSI to determine predicted CSI for a wider bandwidth channel.
