Abstract: A host device may include a first wireless communication circuit, a second wireless communication circuit including a proxy router, and a host processor communicatively coupled to the wireless communication circuits. The host device may receive, via the second wireless communication circuit, an advertisement message from a client device. The advertisement message may include a request for communication of data with a network. The host device may determine at least one of a communication policy preference of the host device and a network connection property of the host device. The proxy router may select the first or the second wireless communication circuit for use by the host device to communicate the data with the network. The host device may provide, via the second wireless communication circuit, a connection request to the client device, and then transfer, using the selected wireless communication circuit, the data between the client device and the network.

Abstract: Disclosed herein are system, method, and computer program product embodiments for selectively decoding a multicast subframe in a multi-user frame for a wireless communications protocol. Embodiments include transmitting a request frame including a multicast group address for a multicast group to an access point (AP). The AP can determine a multicast identifier for the multicast group based on the multicast group address in the request frame. The AP can also transmit a response frame including the determined multicast identifier to a station (STA). The STA can receive a multi-user frame containing a multicast subframe from the AP. The STA can determine whether the multicast subframe is destined for the STA based on the determined multicast identifier and a multicast identifier stored in a preamble of the multi-user frame. The STA can determine whether to decode the multicast subframe based on the determination of whether the multicast subframe is destined for the STA.

Abstract: An access point selects a channel access policy for an electronic device in a wireless local area network (WLAN). During operation, an interface circuit of the access point receives a channel access preference from the electronic device. The channel access preference includes: a multi-user trigger-based channel access technique, a single-user contention-based channel access technique, or both. The interface circuit selects the channel access policy for the electronic device based, at least in part, on the received channel access preference. The channel access policy can also be selected based at least in part on a communication performance metric associated with communication in the WLAN. The interface circuit communicates the selected channel access policy to the electronic device, which subsequently accesses a communication channel and communicates packets with the access point in accordance with the channel access policy.

Abstract: A client device can be configured to identify data to be communicated with a network. In some examples, the client device can determine one or more transient properties of the client device and/or receive a connection request from a host device that is connected to the network, where the connection request comprises one or more connection properties of the host device. In some instances, the client device can also be configured to determine whether the host device is capable of transmitting the data to the network based at least in part on the one or more transient properties of the client device and the one or more connection properties of the host device and/or establish a connection with the host device in accordance with determining that the host device is capable of transmitting the data to the network.

Abstract: An interface circuit in an electronic device (such as an access point) may provide a group wake-up packet to a group of recipient electronic devices in a set of recipient electronic devices. During operation, the interface circuit may select the group in the set of recipient electronic devices, where the group includes at least one of the recipient electronic devices. Then, the interface circuit may provide the group wake-up packet for the recipient electronic devices in the group with information that specifies that a subset of the recipient electronic devices in the group transition from a low-power mode. For example, the information may include a bitmap that specifies the subset and an identifier of the group. Note that the electronic device may dynamically define the group. Alternatively, the recipient electronic devices in the group may be static.

Abstract: This document describes multicast communication between wireless devices. A scheduling frame may be wirelessly transmitted by a wireless device. The scheduling frame may include a multicast address indicating a group of intended receiving devices for a payload frame. The scheduling frame may further include scheduling information indicating an order for the group of intended receiving devices to transmit acknowledgement information for the payload frame. A payload frame may also be wirelessly transmitted by the wireless device. The payload frame may include payload information intended for the group of intended receiving devices. Additionally, acknowledgement frames may be wirelessly received by the wireless device from at least a subset of the group of intended receiving devices. The acknowledgement frames may be received according to the order indicated in the scheduling information.

Abstract: A client device and a host device may create a local connection for providing wide area network access, such as Internet access, to the client device. In some embodiments, the client device may have limited network capabilities and may not be able to access the Internet without the host device. The client device may provide its speed and direction in a message to potential host devices. A host device may calculate a suitability metric, based on the speed and direction of the client as well as connection properties of the networks, which indicates an ability for the host device to connect the client device to the Internet. The host device may provide the suitability metric within a connection request to the client device. Based on the suitability metric and/or other factors, the client device and the host device may establish the local connection.
