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: Systems and methods for improving the performance and stability of bonding radios are provided. One method includes receiving a packet from a client device. Next, the method includes determining whether the received packet is an expected next packet and transmitting the received packet to a next destination if the received packet is the expected next packet. In an event the received packet is not the expected next packet, transmitting the received packet to a queue, setting a timer to wait for the expected next packet, and transmitting a message to the sender of the received packet requesting that the expected next packet be sent.

Abstract: Implementations of the present disclosure relate to a method for decoding error correction. The method comprises detecting a failure of decoding a received frame. After the failure of decoding the received frame is detected, a type of the received frame is determined based on a probability that the received frame follows a prior frame of the received frame in a frame sequence. The method further comprises obtaining a template corresponding to the type of the received frame, and decoding the received frame based on the fixed values in the template. The template includes fixed values corresponding to the type of the received frame. With these implementations, correction ability of the decoding can be obviously improved with assistance of the constructed template.

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: Some examples relate to use of a three-address scheme for forwarding frames in a wireless mesh network (WMN). In an example, a node in a WMN may receive an Ethernet packet from a station outside of the WMN. The Ethernet packet may include a first address scheme comprising a destination address (DA) field, and a source address (SA) of the Ethernet packet. The Ethernet packet may be encapsulated in a second Ethernet packet comprising second address scheme. The second Ethernet packet may be encapsulated in an IEEE 802.11 frame comprising a third address scheme.
