    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: 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 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.

    Abstract: A first wireless access point uses a first radio access technology in a heterogeneous wireless network. The heterogeneous wireless network includes the first wireless access point and a second wireless access point using a second radio access technology. The first wireless access point determines one or more performance characteristics of traffic management and traffic between a first client device and the first wireless access point using the first radio access technology and the second wireless access point using the second radio access technology. The first wireless device (access point or some other network device) calculates one or more traffic indicators based on these performance characteristics. The first wireless device further communicates at least one of the one or more traffic indicators to the second wireless access point. The communicated traffic indicators are for use by the second wireless access point to schedule radio resources of the second RAT.
