Abstract: Systems, methods, and devices for reducing collisions in a wireless communications network are described herein. In one aspect an apparatus for wireless communication is provided. The apparatus includes a transmitter configured to transmit a first message over a communication medium to a plurality of nodes configured to be selectively at least partially powered down during time periods in which the first message is not expected to be transmitted. The first message indicates a subset of the plurality of nodes for which data is available for transmission. The apparatus further includes a controller configured to initiate a process for transmitting the data available to the subset of the plurality of nodes after the first message is transmitted.

Abstract: A method includes transmitting a packet from a first wireless device to a second wireless device, where data within the packet is encoded and a signal representing the packet is modulated in accordance with a modulation and coding scheme (MCS). The method also includes, responsive to receiving an acknowledgement packet that includes a MCS change indicator from the second wireless device via a wireless local area network (WLAN) in response to transmitting the packet, maintaining the MCS when the MCS change indicator has a first value and incrementing the MCS when the MCS has a second value.

Abstract: Systems and methods for communicating in a wireless communication system are described. Various processes for reducing the initial link set up time are described. In one aspect, a method in a wireless communication system is provided. The method includes receiving, at a device, at least two different access request messages each for establishing a link with the device. The method further includes determining a period of time for transmitting access response messages in response to the received access request messages. The method further includes reserving a period of transmission time on a channel for transmitting the access response messages for establishing the link, the reservation based at least in part on the determined period of time. The method further includes transmitting the access response messages during the reserved period of time.

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.
