Abstract: Systems, methods, and devices for compressing block acknowledgment (ACK) frames/packets are described herein. In some aspects, a method of communicating in a wireless network includes generating a block acknowledgment frame comprising a plurality of fields in the following order: a block acknowledgment identifier field including an identifier of the block acknowledgment frame; a starting sequence control field including at least one of a sequence number and a function of a sequence number of a data unit for which the block acknowledgement frame is sent; and a block acknowledgement bitmap field indicating a received status of a number of data units. The method further includes wirelessly transmitting the block acknowledgment frame.

Abstract: This disclosure describes systems, methods, and devices for paging message enhancement, for example, by allowing packets to accumulate in an access point before sending them to a station. In some implementations, a station may not have an immediate use for a packet waiting in an access point's buffer. The station may save energy and reduce medium occupancy by allowing packets to accumulate at the access point and then receiving the accumulated packets in accordance with certain criteria. Such criteria for accumulation may be based on a Quality of Service (QoS) category, the station address, or the station type. The station may set accumulation parameters, such as a maximum occupied buffer size or a maximum time for which a station's packets are delayed for accumulation.

Abstract: Methods, systems, and/or devices are provided that permit data transmissions over unused television channels. A method operational in a receiver device, includes monitoring one or more repurposed channels within a television broadcast frequency spectrum for data waveforms, wherein waveforms of different bandwidths coexist within the one or more repurposed channels, and at least a larger waveform has a first bandwidth larger than a channel bandwidth for each repurposed channel. The method also includes receiving a waveform over a repurposed channel from among the one or more repurposed channels, wherein the received waveform has a second bandwidth smaller than the channel bandwidth. The method further includes processing the received waveform by applying a downclocking factor to a clock of the receiver device that causes the receiver device to process the received waveform according to the second bandwidth to obtain a data payload from the received waveform.

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: A method includes receiving, at a first station of a peer-to-peer infrastructure-less network, a data packet transmitted from a second station of the peer-to-peer infrastructure-less network. The method also includes determining whether to retransmit the data packet to at least one other station in the peer-to-peer infrastructure-less network or whether to suppress retransmission of the data packet based on received signal strengths of received retransmissions of the same data packets from one or more nearby stations.

Abstract: Systems and methods are provided to improve roaming performance and to minimize disruptions in connectivity. When roaming between a source AP and a target AP, the device determines whether the APs employ different gateways, such as through an ARP exchange. If the source and target APs have different gateways, a DHCP exchange is used to renew the IP address of the device to restore network connectivity.
