Abstract: Systems, methods, and computer-readable media for an integrated Wi-Fi Access Point and cellular network Radio Unit (RU) include a communication system interfacing with a wired network for communicating Wi-Fi traffic and cellular network traffic, the communication system integrating a Wi-Fi Access Point (AP) with a cellular network Radio Unit (RU). The Wi-Fi traffic and cellular network traffic can be processed in the communication system. The communication system can interface with at least one programmable Radio Frequency (RF) front end configured for wireless communication over one or more frequency bands for Wi-Fi traffic and one or more frequency bands for cellular network traffic (e.g., 5G, LTE, Wi-Fi).

Abstract: Preamble puncturing configuration information is encoded in a pad field, and alternatively or additionally, in a Service Field, depending on a transmission bandwidth of a Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU). Some implementations also encode one or more parity bits in the pad field or Service field. The PPDU including the preamble puncturing configuration information encodes, in various embodiments, a request to send frame, a clear to send frame, a power save poll frame, or a contention free end frame.

Abstract: A management entity obtains from a first wireless access point a Basic Service Set (BSS) color collision event detected by the first wireless access point. The first wireless access point uses a first BSS color. A color collision event occurs when the first wireless access point receives from a device in a BSS of a different physical wireless access point a frame or PHY Protocol Data Unit (PPDU) that includes the first BSS color. The management entity obtains from the first wireless access point an indication whether the color collision event has been detected for longer than a predetermined duration. When the color collision event has been detected for longer than the predetermined duration, the management computes a probability of the color collision event. The management entity determines whether the color collision event is malicious or benign, and determines whether to maintain the first BSS color.

Abstract: A wireless access point device is full-duplex capable and serves wireless communication for at least first and second wireless client devices. The wireless access point device sends to the first wireless client device a trigger frame that causes the first wireless client device to send an uplink transmission to the wireless access point after a first time interval. The wireless access point device waits a second time interval after the first wireless client is expected to begin sending the uplink transmission. The wireless access point device receives the uplink transmission from the first wireless client device. After the second time interval, and while receiving the uplink transmission from the first wireless client device, the wireless access point device sends to the second wireless client device a downlink transmission that overlaps at least partially in frequency and time with the uplink transmission from the first wireless client device.

Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media for identifying a location of a wireless device. A method for identifying a location of a wireless device includes transmitting a request message to the wireless device for identifying a position of the wireless device; receiving a response message from the wireless device; determining first time information based on a time of flight (ToF) of the request message and the response message, wherein the ToF corresponds to a distance of the wireless device from the AP; receiving a second message from a second AP that includes second time information associated with the request message and the response message; receiving a third message from a third AP that includes third time information associated with the request message and the response message; and transmitting location configuration information to the wireless device for the wireless device to determine a position of the wireless device.

Abstract: A method is provided in which an AP of a MLD AP device may decide to include all out-of-link BSS parameters updates in a beacon frame (beacon). A flag is included in the beacon frame to indicate that all updates are included in the beacon frame and thus the client device that receives the beacon frame should not send probe request frames (probe requests) to obtain these updates. Thus, a non-AP MLD that receives a beacon frame with the above indication and that has all critical BSS parameters corresponding to the Change Sequence Number (CSN) that preceded the updates indicated by the AP, should not send probe requests to obtain the updated parameters. The number of bits to assign to the complete BSS Update Report Indication flag may vary depending on the number of updates to be reported.
