Methods, systems, and devices for exchanging subband puncture information for network throughput management are described. In some examples, an access point may receive an action frame from a station device, which includes a disabled subchannel bitmap subfield that indicates subband puncturing information based on localized interference detected by the station device. The access point may then determine a negotiated subband puncturing pattern that considers both the station device's and the access point's detected subband puncturing information. Subsequently, the access point may transmit an action frame back to the station device containing this negotiated subband puncturing pattern. Both the access point and the station device may adhere to this negotiated subband puncturing pattern for future unicast frame exchanges, thereby enhancing network efficiency by effectively managing packet transmissions and reducing packet collisions.

The disclosure describes systems and methods for establishing a constant bit rate data pipe between access points and stations. An access point can receive, from a station, a request indicating a bandwidth for a low latency application running on the station. Responsive to acceptance of the request by the access point, the station can withhold transmissions of a request-to-send (RTS) frame to the access point. The access point can determine, based at least on the bandwidth of the request, a frequency by which to send a clear-to-send (CTS) frame to the station. The access point can transmit the CTS frame to the station according to the determined frequency.

In an embodiment, a packaged integrated circuit device includes a package substrate. The package substrate may be flip-chip type package substrate. A layer is disposed on the package substrate. An interposer is disposed on the layer. This layer may have passthrough type through vias permitting electrical interconnections between the package substrate and the interposer. The interposer may have various wiring layers and circuit components therein. One or more dies are disposed on the interposer. A die may be an application specific integrated circuit devices, a high-speed memory device, or the like. The layer has a coefficient of thermal expansion that is between a coefficient of thermal expansion of the interposer and a coefficient of thermal expansion of the package substrate. The layer can function to intermediate stresses or strains arising during manufacturing and/or operation related to thermal expansion differences in components.

The subject technology is directed to signal processing systems and methods. In an embodiment, the subject technology provides an apparatus that includes a first input terminal and a second input terminal configured to receive respective input signals. A first converter and a second converter generate corresponding output signals based on the input signals. A first circuit, coupled to both converters, determines a gain mismatch between them based on their output signals and adjusts at least one of the signals to compensate for the mismatch. By compensating for gain mismatch in the digital domain, the apparatus improves the common-mode rejection ratio (CMRR) and enhances the accuracy and reliability of analog-to-digital conversion. There are other embodiments as well.

An access point (AP) point in a wireless local area network (WLAN) may include circuitry configured to transmit, to a station (STA) in the WLAN, a beacon including a beacon payload. A first set of information elements associated with the access point may be advertised within the beacon payload. The beacon payload may include an indicator indicating that the AP is associated with a second set of information elements that is not advertised in the beacon payload. The STA may include circuitry configured to transmit, to the AP, a request for the second set of information elements. The STA may receive, from the AP and in response to the request, a response including an indication of the second set of information elements.

An access point (AP) may establish multiple virtual networks in a wireless local area network (WLAN) that are associated with a basic service set identifier (BSSID) of the AP and unique service set identifiers (SSIDs). The AP may transmit, to a station (STA) in the WLAN, a beacon including beacon data indicating the BSSID and at least one of an SSID that is not associated with the multiple virtual networks or an indicator that the AP is associated with one or more virtual networks. The STA may determine, based on the BSSID, to connect to a virtual network of the multiple virtual networks. The STA may transmit, to the AP, a request for discovery of the virtual network indicating a unique SSID of the virtual network. The STA may receive, from the AP and based on the request, a response confirming that the virtual network is available.

A user device is configured to provide device assistance to a user of the user device, by performing the steps of: detecting a query provided by the user, the query prompting the user device for help resolving an issue; generating user manual context using a retrieval-augmented generation (RAG) neural network; identifying, from state information about the user device, a subset of the state information that is associated with the query; generating device assistance information for the issue using a local language neural network, the device assistance information containing at least one of: (1) identification of a system action for the user device to perform and (2) a message for the user; in response to the device assistance information identifying the system action, executing the system action at the user device; and in response to the device assistance information containing the message, outputting the message from the user device.

A station (STA) may connect to an access point (AP) via a plurality of wireless links. The STA may determine to transition a power management state of at least a first wireless link, of the plurality of wireless links, to a transitioned state. The STA may transmit, to the AP and over an available wireless link of the plurality of wireless links, a frame including protected data indicating the transitioned state of the first wireless link. The AP may transition the first wireless link to the transitioned state.

Methods, systems, and devices for synchronizing Bluetooth access grants in Wi-Fi-connected devices are described. In some implementations, a method may include establishing a Wi-Fi connection between a first device and a second device, both equipped with Bluetooth capabilities. The method may involve determining a target beacon transmit time for the Wi-Fi connection and synchronizing Bluetooth access grants between the first and second devices based on the target beacon transmit time. Consequently, medium access may be granted to Bluetooth on both the first and second devices simultaneously in response to the synchronized Bluetooth access grants, thereby enhancing the efficiency of medium usage and improving overall device coexistence and performance in Wi-Fi/Bluetooth combination environments.

A mixed-signal unit including a sampler circuit and a tracking filter. The sampler circuit converts a code into a reference signal. In response to comparing an input signal to the reference signal, the sampler circuit produces a bitstream. Upon receiving the bitstream from the sampler circuit, the tracking filter updates the code using information contained in the bitstream. The tracking filter outputs the code to the sampler circuit in response to the tracking filter updating the code.
