    Abstract: In embodiments of the present disclosure, there is provided an approach for performing channel scan by utilizing a target wake time (TWT) mechanism. According to embodiments of the present disclosure, a compound AP transmits, to an uplink AP, a request to negotiate a schedule for a TWT session. The compound AP receives a response to the request from the uplink AP. The response comprises timing information of the TWT session. Then, the compound AP performs channel scan during a sleep period determined from the timing information. Data transmission between the compound AP and the uplink AP is disabled during the sleep period. Embodiments of the present disclosure provide an effective way for performing the channel scan, thereby ensuring data delivery and enhancing connection robustness between the compound AP and the uplink AP.

    Abstract: In embodiments of the present disclosure, there is provided an approach for managing Target Wake Time (TWT) clients in a congested environment. According to embodiments of the present disclosure, a TWT client transmits, to an AP, a request to negotiate a schedule for a TWT session. The request comprises a first set of TWT parameters requested by the TWT client. The AP determines, based on respective sets of TWT parameters of existing TWT sessions and the first set of TWT parameters, a second set of TWT parameters for the TWT client to minimize overlap between the TWT session and the existing TWT sessions. The AP transmits a response comprising the second set of TWT parameters to the TWT client. Embodiments of the present disclosure provide an effective way for assigning air resources to multiple TWT clients in a congested environment, thereby reducing collisions among TWT sessions.

    Abstract: Maintenance and monitoring of target wait time (TWT) sessions is described. An example includes establishing at least a first target wake time (TWT) session for a first station, the first TWT session having a first set of parameters defining a wake time, wake duration, and wake interval for service periods of the first TWT session; selecting the first TWT session for health status determination; selecting a check window for the health status determination and monitoring transmissions from the first station within the check window; based at least in part on the monitoring of the transmissions from the first station, calculating a first TWT session health status value for the first TWT session; and determining whether corrective action is required for the first TWT session based at least in part on the first TWT session health status value.

    Abstract: A network device may comprise a plurality of antennas; a processor; and a non-transitory computer readable medium storing a plurality of codebooks, each of the plurality of codebooks comprising instructions to test communication capabilities of the network device using a particular configuration of the plurality of antennas, in response to a first boot of the network device, the processor causing the network device to: load a first codebook of the plurality of codebooks; test the particular configuration of the plurality of antennas associated with the first codebook; store a first result comprising the communication capability of the first codebook; load a second codebook of the plurality of codebooks; test the particular configuration of the plurality of antennas associated with the second codebook; store a second result comprising the communication capability of the second codebook; and select the first codebook or the second codebook based on the first result or the second result.

    Abstract: Systems and methods are provided for upgrading wireless network devices, such as access points (APs). When a first AP needs an upgrade, a network controller of the first AP may identify and select a neighbor AP. The radio(s) of the neighbor AP can be split into multiple logical radios, at least one of which includes a backup virtual AP (VAP). The backup VAP can support client devices originally supported by the first AP, allowing those client devices to roam to the neighbor AP while the first AP is upgrading, and without needing to re-associate with the neighbor AP. From the client device perspective, it appears as though they are still being supported by the first AP. Upon upgrading the first AP, the client devices can roam back to the first AP (without needing to re-associate with the first AP). No downtime is experienced, and no RF holes are generated.

    Abstract: In embodiments of the present disclosure, a method is provided for performing a frame processing operation on a broadcast/multicast frame at a physical access point (AP). A pre-processing operation is performed on the frame at a protocol layer between a physical layer and an upper layer of the AP to obtain a pre-processed frame. The pre-processing operation comprises a common operation to be performed for the plurality of virtual interfaces at the protocol layer. In this way, by performing a pre-processing operation common to the virtual interfaces supported by the physical AP, the consumption of resources caused by the performance of repeated operations in the frame processing operation can be reduced.
