20100098080 | Payload Header Suppression with Conditional Field Suppression - A conditional payload header suppression is disclosed to improve compression, by providing the flexibility to dynamically introduce fields/header bytes, which change temporarily or infrequently in packets. The embodiment also uses a dynamic mask as part of the payload header suppression packet to indicate which of the conditionally suppressed header bytes are present in the packet sent over the air or the communication medium. An embodiment of this invention increases the header compression for packets such as IP/UDP/RTP (VOIP) and TCP ACK in communication networks, such as WiMax. | 04-22-2010 |
20110026446 | Variable short interframe space - Apparatuses, systems, and methods for transmitting data frames over data networks with varying Interframe Space (IFS) times are disclosed. A system embodiment may comprise a mobile computing device with an integrated wireless networking card. The card may receive a transmission of several data frames. While receiving the several data frames, the networking card may determine that a response will need to be transmitted back to the sending station after the sending station sends the last frame of data. After a short period of delay following the end of the last transmitted frame the card may immediately begin transmitting a preamble of the response, while still demodulating and processing data of the transmitted frames. Upon finishing data processing of the remaining frames, the card may generate the content for the rest of the response, such as a block acknowledgment. | 02-03-2011 |
20110080887 | AGGREGATED TRANSMISSION IN WLAN SYSTEMS WITH FEC MPDUs - In various embodiments, a wireless device may determine the quality of a channel by transmitting at least one packet to another device and receiving from that other device an indicator of the quality of the channel. Based on the quality indicator, the device may determine an estimated packet error rate, and subsequently transmit few enough packets that if the estimated percentage of those packets fail, there will be time to retransmit them. | 04-07-2011 |
20110149723 | Packet-loss handling for downlink multi-user multiple- input and multiple-output wireless network - Techniques for packet-loss handling for downlink Multi-User Multiple-input and Multiple-Output (DL MU-MIMO) wireless networking environment are described herein. The techniques described herein help define how a wireless access point should behave when faced with a packet-loss situation of a DL transmission burst in a MU-MIMO wireless network. | 06-23-2011 |
20110154038 | Multi-band/multi-link secure key generation and delivery protocol - A method is described for negotiating the use of multi-link ciphering and for the generation of unique keys for each of the links using a single 4-way handshake protocol exchange. | 06-23-2011 |
20110158110 | METHOD AND SYSTEM FOR MULTIBAND RATE SCALING - A system and method for multiband rate scaling for communication, particularly wireless communication. A band is used as a parameter for wireless communication performance when a wireless communication channel has a plurality of available bands for communication. A selected communication band may be switched to another available communication band, where the switching may be based on a desired performance determination. | 06-30-2011 |
20110188518 | Coded bit padding - A method is described for adding coded bit padding for a orthogonal frequency division multiplexing (OFDM) data transmission device. | 08-04-2011 |
20110268094 | Systems and methods for uplink multi-user multiple input multiple output (MU MIMO) medium access and error recovery - Embodiments of systems and methods for uplink multi-user multiple input multiple output (MU MIMO) medium access and error recovery are generally described herein. Other embodiments may be described and claimed. | 11-03-2011 |
20120082040 | METHOD AND APPARATUS FOR COLLISION DETECTION IN WIDER BANDWIDTH OPERATION - Embodiments of systems and methods for providing collision detection in a wider bandwidth are generally described herein. Other embodiments may be described and claimed. | 04-05-2012 |
20120163354 | SINGLE MPDU FRAME SIGNALING - Embodiments of systems and methods for providing single MPDU frame signaling are generally described herein. Other embodiments may be described and claimed. | 06-28-2012 |
20130132500 | SELECTION OF A MASTER IN A PEER-TO-PEER NETWORK ENVIRONMENT - A system, apparatus and method for selecting master devices in a peer-to-peer communication environment. Devices select a master to facilitate their synchronization, and rendezvous according to a schedule of availability windows broadcast by the master as part of periodic synchronization frames. Devices capable of serving as master advertise their selection metrics, which are converted into a master preference value by a selection algorithm applied uniformly by all devices in the environment. Individual devices may identify the best local master and synchronize to it, yielding a cluster of synchronized peers. Clusters may then be synchronized to masters at further range. Individual devices conserve power by being automatically synchronized instead of having to individually discover other devices and services, and can power off their radios without sacrificing discoverability. Synchronization and peer-to-peer communication as provided herein coexists with other device demands, such as Bluetooth® operations, infrastructure-based communications and so on. | 05-23-2013 |
20130132501 | SYNCHRONIZATION OF DEVICES IN A PEER-TO-PEER NETWORK ENVIRONMENT - A system, apparatus and method for synchronizing devices in a peer-to-peer communication environment. Devices select a master to facilitate their synchronization, and rendezvous according to a schedule of availability windows broadcast by the master. Devices may attend some or all of the availability windows, during which they may send and receive unicast and/or multicast messages. Individual devices conserve power by being automatically synchronized instead of having to individually discover other devices and services, and can power off their radios without sacrificing discoverability. Synchronization and peer-to-peer communication as provided herein coexists with other device demands, such as Bluetooth® operations, infrastructure-based communications and so on. | 05-23-2013 |
20130148529 | METHOD AND SYSTEM FOR MULTIBAND RATE SCALING - A system and method for multiband rate scaling for communication, particularly wireless communication.

20150078366 | MULTI-CARRIER CONFIGURATION, ACTIVATION AND SCHEDULING - Embodiments of block acknowledgements request apparatus, systems, and methods are generally described herein. Other embodiments may be described and claimed. An aggregated block of a plurality of data frames is received from an originator transmission, with each data frame including a medium access control (MAC) header. An acknowledgement policy that is solicited by the originator is identified in a quality of service field in at least one of the MAC headers of the received transmission. A single block acknowledgement is transmitted to the originator acknowledging receipt of one or more of the plurality of data frames in the aggregated block of data frames. | 03-19-2015 |
