Abstract: A method for harmonic channel detection is provided. The method comprises receiving, by a first AP working on a first channel, a beacon frame transmitted by a second AP and parsing the beacon frame to obtain information of a second channel indicated in the beacon frame. The method further comprises determining a plurality of candidate harmonic channels and validating that the second channel is one of the candidate harmonic channels. In addition, the method further comprises validating that the beacon frame is transmitted on the second channel based on a sequence number and a TBTT indicated in the beacon frame and discarding the beacon frame. Implementations of the present disclosure can reduce harmonic frames from being reported to a controller at upper layer, and improve the performance of the network.

Abstract: Implementations of the present disclosure relate to resource allocation for clients of multiple co-hosted virtual access points (VAPs). A method comprises determining, by an access point (AP), a plurality of trigger frames for a plurality of clients connected to a plurality of VAPs of the AP based at least in part on respective workload levels of the plurality of clients. A trigger frame indicates a resource unit of one of the plurality of VAPs available for at least one corresponding client to access to the VAP. The method also comprises transmitting, by the AP, the plurality of trigger frames in parallel to the plurality of clients. By transmitting separate trigger frames for different clients in parallel, the efficiency of trigger frames can be improved and higher quality of service and lower collision will be provided.

Abstract: In embodiments of the present disclosure, there is provided an approach for selecting a channel puncturing scheme based on channel qualities. A method comprises detecting channel interference between neighbor access points (APs), and determining whether a preamble puncturing needs to be enabled based on some puncturing conditions. After determining that a preamble puncturing needs to be enabled, scores for candidate puncturing patterns are calculated based on channel qualities of the sub-channels in the channel, and a proper puncturing pattern can be selected based on the respective scores. Embodiments of the present disclosure can help AP to achieve an effective and better puncturing scheme in real deployment.

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: Operation of a wireless network access point (AP) to communicate with a first set of one or more wireless client devices using a wireless protocol in which spatial reuse of channels is supported via at least a dynamically configurable basic service set (BSS) identifier of the wireless AP. The BSS identifier is utilized to identify overlapping BSSs (OBSSs). A first set of one or more wireless client devices communicate using a wireless protocol in which spatial reuse of channels is supported via at least a dynamically configurable BSS identifier of the wireless AP. The BSS identifier is utilized to identify OBSSs. Unauthorized network activity is detected based on the BSS identifier and a received BSS identifier associated with the received transmissions. A dynamic adjustment is made to one of the BSS identifiers of the AP or the received BSS identifier in response to detected unauthorized network activity.

Abstract: Systems and methods are described for prioritizing channel access to uplink (UL) multi-user (MU) data capable active stations (STAs) by dynamically adapting a MU enhanced distributed channel access (EDCA) parameter set to provide for increased access to the channel by the UL MU data capable active STAs when the total number of active STAs associated to the AP less the number of active UL MU capable STAs exceeds the number of active UL MU data capable STAs; and by dynamically adapting the MU EDCA parameter set to equal a legacy EDCA parameter set to reduce collisions between the UL MU data capable STAs when the number of active UL MU data capable STAs exceeds or equals the total number of active STAs associated to the AP less the number of active UL MU data capable STAs.
