    Abstract: Systems, methods, and devices for communicating frames having a plurality of types are described herein. In some aspects, the frames include a compressed frame, such as a compressed management frame or a compressed control frame. In some aspects, a method of communicating in a wireless network includes generating a management frame including a local identifier or a global identifier for a transmitter of the management frame based on a link type over which the management frame is transmitted, a local identifier or a global identifier for a recipient of the management frame based on the link type, a frame check sequence, and information indicating the link type. The method further includes transmitting the management frame.

    Abstract: An access point may advertise (e.g., broadcast) identifying information (e.g., a neighbor report and access point capability information) on a dedicated channel in a wireless network. The identifying information may include information about neighboring access points in the wireless network. The neighboring access points may operate on the dedicated channel, a different primary operating channel, or a combination thereof. A station entering the wireless network may scan the dedicated channel to detect the identifying information from the access point to aid relatively quick discovery of the neighboring access points without scanning multiple channels.

    Abstract: Systems, methods, and devices for communicating packets having a plurality of types are described herein. In some aspects, the packets include a compressed header. In one embodiment, a compression protocol is selected from a plurality of compression protocols to compress a first packet header. The packet may contain a second packet header, which may include information indicative of the compression protocol used to compress the first packet header. The packet may be transmitted, including the first packet header which is compressed using the selected compression protocol.

    Abstract: Devices, systems and methods are described for mitigating interference in a wireless communications network. In particular, the network may be a Wi-Fi network. Multiple approaches may be implemented to mitigate ACI. Further, multiple approaches may be implemented to mitigate non-Wi-Fi interference as well. Each of the approaches may consist of two parts, namely, interference detection and interference mitigation (or reduction). One approach may involve: detecting adjacent channel interference (ACI) in an operating channel of the device; determining a location of the detected ACI in an operating band of the device; and mitigating the detected ACI by communicating via a channel different from the operating channel, the different channel being determined to be further away from the location of the detected ACI.

    Abstract: A method includes receiving, at a wireless device, a frame via a sub-1 gigahertz (GHz) wireless network. The frame includes a signal (SIG) unit including a length field and an aggregation field. The length field may be interpreted as a number of bytes or as a number of symbols based on a value of the aggregation field and based on whether the frame is associated with a 1 megahertz (MHz) bandwidth mode, based on whether the frame includes either a short format preamble or a long format preamble, or based on whether the frame is determined to be a single user (SU) frame or a multi user (MU) frame.

    Abstract: A system and method for reliable multicast communications is disclosed herein. In one aspect, a first station may receive a first multicast frame having a first modulation and coding scheme and a first sequence number. The station may then receive a subsequent negative acknowledgement request having a second modulation and coding scheme and a indicating a second sequence number for previously transmitted multicast frame, with the second modulation and coding scheme having a lower data rate than the first modulation and coding scheme. The station may then selectively acknowledge the negative acknowledgement request based on a comparison of first sequence number and the second sequence number. In another aspect, the station transmits a negative acknowledgement if the second sequence number does not match the first sequence number and may further receive acknowledgement frame from an access point.
