| 20080198760 | TRAINED DATA TRANSMISSION FOR COMMUNICATION SYSTEMS - Various embodiments are described for a trained data transmission for communication systems. | 08-21-2008 |
| 20090122694 | Method for signaling information by modifying modulation constellations - Methods and systems for communicating in a wireless network may distinguish different types of packet structures by modifying the phase of a modulation constellation, such as a binary phase shift keying (BPSK) constellation, in a signal field. Receiving devices may identify the type of packet structure associated with a transmission or whether the signal field is present by the phase of the modulation constellation used for mapping for the signal field. In one embodiment, the phase of the modulation constellation may be determined by examining the energy of the I and Q components after Fast Fourier Transform. Various specific embodiments and variations are also disclosed. | 05-14-2009 |
| 20090213865 | Techniques for channel access and transmit queue selection - Various embodiments are disclosed for techniques to perform channel access decisions and to select a transmit queue. These decisions may be performed, for example, based upon the age and number of packets in a queue. These techniques may allow a node to improve the length of data bursts transmitted by the node, although the invention is not limited thereto. | 08-27-2009 |
| 20100165896 | Power saving in peer-to-peer communication devices - Apparatuses, systems, methods, and computer program products to save power in peer-to-peer communication devices associated with wireless communication networks are disclosed. Embodiments generally comprise wireless communications devices. A device may associate or connect with an access point and communicate with another device also connected to the access point. The devices may establish a direct link as part of a tunneled direct link system (TDLS) network. After establishing the direct link, the devices may negotiate a wakeup schedule, enabling both devices to enter power saving modes to conserve power. The devices may maintain the direct link while in power saving modes, enabling the devices to periodically exit the power saving modes and transfer buffered data. | 07-01-2010 |
| 20100208579 | ADAPTIVE USE OF A TRANSMIT OPPORTUNITY - Various embodiments are described to adaptively use a transmit opportunity. | 08-19-2010 |
| 20100322130 | Techniques for broadcast/multicast delivery in wireless networks - An embodiment of the present invention provides an apparatus including a transceiver operable for broadcast/multicast traffic delivery in a wireless network, wherein the transceiver is adapted to identify local broadcast traffic and limit a broadcast domain to a basic service set (BSS) servicing the local broadcast traffic. | 12-23-2010 |
| 20110013524 | TRAINED DATA TRANSMISSION FOR COMMUNICATION SYSTEMS - Various embodiments are described for a trained data transmission for communication systems. | 01-20-2011 |
| 20110044392 | Systems And Methods For High-Throughput Wideband Wireless Local Area Network Communications - A frame format provides for wideband wireless local area network communications and informs narrower-band communication units when the channels are occupied by wider-band communication units. In some embodiments, the frame format includes a channelization field identifying channels that are used for communicating subsequent wideband fields of a packet, and a wideband-header field communicated on the identified channels. The wideband-header field may identify sub-fields that may be present in the wideband-header field, and may identify the presence of a wideband-data field. A long-compatibility field may be present that provides protection at the MAC level. The long-compatibility field may transport MAC frames that may include medium-reservation information compatible with narrower-band communication units. | 02-24-2011 |
| 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 |
| 20110149936 | METHODS FOR TRANSMITTING CLOSELY-SPACED PACKETS IN WLAN DEVICES AND SYSTEMS - A wireless local area network (WLAN) device transmits a header over an air interface, at a first modulation rate. The header may include an indication of a second modulation rate that will be used to transmit a consolidated payload. The device further transmits the consolidated payload at the second modulation rate. The consolidated payload includes multiple data units. In one embodiment, the consolidated payload includes delimiters with validation fields associated with the various data units. | 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 |
