摘要： This disclosure describes systems, methods, and devices related to multi-user uplink channel sounding. A device may determine a channel sounding sequence with one or more access points (APs), wherein the channel sounding sequence comprises a null data packet announcement (NDPA) communicated with at least one of the one or more APs. The device may determine a first group of station devices (STAs) associated with a first basic service set (BSS). The device may cause to send a trigger frame to the first group of STAs to solicit an uplink NDP from each STA of the first group of STAs. The device may identify a first uplink NDP received from a first STA of the first group of STAs. The device may identify a second uplink NDP received from a second STA of a second group of STAs.

摘要： The application relates to ultra-low latency data transmission in Wireless Local Area Networks (WLANs). An apparatus used in a non-Access Point Station (non-AP STA), includes processor circuitry configured to cause the non-AP STA to, when there is urgent data that must be transmitted in uplink without waiting for a scheduled slot: generate a Protocol Data Unit (PDU) from the urgent data; and transmit the PDU on a resource unit pre-assigned for urgent transmission, wherein the resource unit is multiplexed for uplink transmission from multiple non-AP STAs.

摘要： Systems, apparatuses and methods may provide for technology that generates, via a first neural network such as a grid network, a first vector representing a prediction of future behavior of an autonomous vehicle based on a current vehicle position and a vehicle velocity. The technology may also generate, via a second neural network such as an obstacle network, a second vector representing a prediction of future behavior of an external obstacle based on a current obstacle position and an obstacle velocity, and determine, via a third neural network such as a place network, a future trajectory for the vehicle based on the first vector and the second vector, the future trajectory representing a sequence of planned future behaviors for the vehicle. The technology may also issue actuation commands to navigate the autonomous vehicle based on the future trajectory for the vehicle.

摘要： This disclosure relates to a method for radar signal detection, the method comprising: scanning a radio channel by a scanning filter in a first frequency subband to provide an incoming signal; detecting a potential radar signal in the incoming signal based on prior knowledge of a structure of the radar signal; and if the potential radar signal is detected, keeping the scanning filter in the first frequency subband; if no potential radar signal is detected, adjusting the scanning filter to a second frequency subband.

摘要： Optical signaling is implemented by modulating visible light with variable pulse position modulation (VPPM). VPPM is a composite waveform and its optical signal includes a Start Frame Delimiter (SFD) which indicates start of optical signaling. To identify modulated lights, the duty cycle is periodically changed in the waveform to induce an AM envelope at a frequency higher than the response of the human eye. The signal is then sampled via a camera producing an alias frequency that produces noticeable blinking. Because the communication is asynchronous, the desired camera frame rate (fc) in relationship to the modulation bit rate timing clock (or symbol rate, fs) is only approximate. Consequently, a frequency offset develops between the camera frame rate (fc) and the symbol rate (fs) in transmission of long packets. The disclosed embodiments provide a detection algorithm, system and apparatus to provide clock offset tracking and correction.

摘要： A communication device can be configured to detect radar signals within an operating channel. The communication device can include a mixer, filter, scanning and spreading circuit and a radar signal detector. The mixer can be configured to modulate a received communication signal based on an oscillating signal to generate a modulated signal. The filter can have a first bandwidth and be configured to filter the modulated signal. The scanning and spreading circuit can be configured to control the oscillating signal to scan an operating channel having a second bandwidth. The second bandwidth can be greater than the first bandwidth. The radar signal detector can be configured to detect a radar signal within the scanned operating channel.

摘要： An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.

摘要： Systems, apparatuses and methods may provide for technology that obtains categorization information and corresponding uncertainty information from a perception subsystem, wherein the categorization information and the corresponding uncertainty information are to be associated with an object in an environment. The technology may also determine whether the corresponding uncertainty information satisfies one or more relevance criteria, and automatically control the perception subsystem to increase an accuracy in one or more subsequent categorizations of the object if the corresponding uncertainty information satisfies the one or more relevance criteria. In one example, determining whether the corresponding uncertainty information satisfies the relevance criteria includes taking a plurality of samples from the categorization information and the corresponding uncertainty information, generating a plurality of actuation plans based on the plurality of samples, and determining a safety deviation across the plurality of actuation plans, wherein the relevance criteria are satisfied if the safety deviation exceeds a threshold.
