Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a retransmission protocol in a wireless local area network (WLAN). The retransmission protocol enables a sending station (STA) to communicate additional parity bits associated with an original transmission that included forward error correction (FEC) encoded codewords. Several techniques are described for a receiving STA to indicate which portions of the original transmission was not properly received. The receiving STA may store the original transmission for use with additional parity bits in a subsequent transmission. The sending STA may communicate the additional parity bits in a subsequent transmission to assist the receiving STA recover the data from the original transmission.

Abstract: A method includes, prior to authenticating a mobile device, receiving by an access point a first message from the mobile device, determining that the mobile device is to be authenticated prior to responding to the first message, and sending to an authentication server a second message that includes an authentication request and the first message. The method also includes receiving from the authentication server a third message that includes a response to the authentication request and that further includes the first message.

Abstract: Systems, methods, and devices for transmitting data are described herein. In some aspects, a method comprises generating a first message. The first message may comprise an allocation of a first station to a first frequency channel and a second station to a second frequency channel. The method further comprises transmitting the first message over the first frequency channel and the second frequency channel. The method further comprises transmitting, after transmission of the first message, a second message to the first station using the first frequency channel. The method further comprises transmitting, after transmission of the first message, a third message to the second station using the second frequency channel.

Abstract: Systems, methods, and devices for high-efficiency wireless frequency division multiplexing are provided. A method includes exchanging, at an access point, at least one frame reserving a wireless medium with at least one of a first and second wireless device. The method further includes receiving a first communication on a first set of wireless frequencies from the first wireless device. The method further includes receiving a second communication, at least partially concurrent with the first communication, on a second set of wireless frequencies from the second wireless device. The method further includes transmitting at least one acknowledgment of the first and second communication. The first set and the second set are mutually exclusive subsets of a set of wireless frequencies available for use by both the first and second wireless device.

Abstract: A communication device for allocating tones is described that includes a processor and instructions in memory in electronic communication with the processor. The communication device determines whether a bandwidth for signal transmission is 20, 40, 80 or 160 megahertz (MHz). The communication device respectively allocates tones for 20, 40, 80 or 160 MHz as follows: for a very high throughput (VHT) signal A1 (VHT-SIG-A1): 52, 104, 208, 416; a VHT signal A2 (VHT-SIG-A2): 52, 104, 208, 416; a VHT short training field (VHT-STF): 12, 24, 48, 48; one or more VHT long training field(s) (VHT-LTF(s)): 56, 114, 242, 484; a VHT signal B (VHT-SIG-B): 56, 114, 242, 484; and a data field (DATA): 56, 114, 242, 484. The communication device also transmits the signal.

Abstract: An acknowledgment (ACK) frame has two parts: a group ACK part and a scheduling information part. In the group ACK part, an ACK/NACK indicator is included for a previous uplink (UL) transmission per station (STA). In the scheduling information part, information included for the following UL transmission per selected STA may comprise, for example, one or more of: a number of selected STAs, a media access control (MAC) address of each selected STA, a data transmission duration per selected STA, a transmission rate per selected STA, a request transmission duration, a pilot transmission order, or a STA transmission order.

Abstract: A method and apparatus for managing access to a wireless medium by one or more stations (STAs) in a wireless network. A device determines a first transmit opportunity for a first STA of the one or more STAs in the wireless network. The device enables the first STA to access the wireless medium for a duration of the first transmit opportunity by broadcasting a first grant message to the one or more STAs in the wireless network. The first grant message indicates allocation of the first transmit opportunity to the first STA. The device may selectively adjust the duration of the first transmit opportunity based at least in part on one or more properties of the wireless network.
