20100226343 | METHOD AND SYSTEM FOR SHARED COMMUNICATION MEDIUM IN WIRELESS COMMUNICATION SYSTEMS - Performing distributed contention-free communication channel reservation for wireless communication, is disclosed. One implementation involves providing access to a shared communication channel in a wireless network including multiple wireless stations, by performing distributed channel time reservation for contention-free access to a shared wireless channel by each wireless station, based on a prior successful contention by the wireless station for access to the channel in a wireless network. | 09-09-2010 |
20100265392 | METHOD AND SYSTEM FOR PROGRESSIVE RATE ADAPTATION FOR UNCOMPRESSED VIDEO COMMUNICATION IN WIRELESS SYSTEMS - Uncompressed video information is transmitted over a wireless communication medium from a wireless sender device to a wireless receiver device. Progressive transmission data rate adaptation is performed on original uncompressed video pixel information. The progressive transmission data rate adaptation is performed on selected pixel information to obtain a rate-reduced pixel information. The rate-reduced pixel information requires a lower transmission data rate than the original frame. The rate-reduced pixel information is transmitted over the wireless communication medium to the wireless receiver device. At the receiver, a reverse operation is performed to recover the original uncompressed video pixel information. | 10-21-2010 |
20110069636 | METHOD AND SYSTEM FOR AD-HOC COMMUNICATIONS OVER MILLIMETER WAVE WIRELESS CHANNELS IN WIRELESS SYSTEMS - A method and system for wireless data communication for peer wireless stations in a network is provided. A pair of peer wireless stations perform discovery on a predefined wireless communication channel to discover each other. Upon peer wireless stations successfully discovering one another, a wireless communication channel is selected to setup a connection between the peer wireless stations for data communication on the selected wireless communication channel. The peer wireless stations then perform connection setup and data communication over the selected wireless channel. In one implementation, the network comprises a wireless local area network (WLAN) for ad-hoc Independent Basic Service Set (IBSS) peer-to-peer communication. Further, the peer wireless stations conduct millimeter wave (mmWave) directional data transmissions between the peer wireless stations on the selected wireless data communication channel. | 03-24-2011 |
20110069647 | METHOD AND SYSTEM FOR WIRELESS COMMUNICATION OF AUDIO IN WIRELESS NETWORKS - A method and system for audio transmission in a wireless communication system which transmits digital video and digital audio in High-Definition Multimedia Interface (HDMI) format. Position information of audio packets within the HDMI frame is obtained. Digital audio information including the position information is transmitted from a data source device to a data sink device via a wireless communication medium. At the data sink device, an HDMI frame is reconstructed by inserting received audio packets into horizontal and vertical blanking periods of the HDMI frame. | 03-24-2011 |
20110070928 | METHOD AND SYSTEM FOR ANNOUNCEMENT TIME OF IDLE TIMEOUT FOR POWER SAVING OPERATIONS IN WIRELESS NETWORKS - A method and system for wireless communication over a wireless communication medium is provided. A schedule is generated which indicates when a wireless communication station may enter a power saving state in an announcement time (AT) period, based on an idle timeout interval in the AT period. The AT period comprises a period after a beacon transmission in a beacon interval. | 03-24-2011 |
20110096681 | METHOD AND SYSTEM FOR DIGITAL CONTENT PROTECTION LOCALITY CHECK WITH ADAPTIVE TIMELINE IN WIRELESS COMMUNICATION SYSTEMS - A method and system for data communication in a wireless network is provided. A wireless transmitter transmits a locality check message from a wireless transmitter to a wireless receiver over a wireless communication medium. Upon receiving a locality check response message from the wireless receiver, the wireless transmitter marks the locality check response message as valid even if it arrives after an original locality check time period since transmission of the locality check message, but before the end of an adjusted locality check time period. The adjusted locality check time period comprises said original locality check time period adjusted by delays in processing layers at the transmitter and wireless communication medium access delays in data communication between the wireless transmitter and the wireless receiver. | 04-28-2011 |
20110116458 | METHOD AND SYSTEM FOR SELECTIVE SCALABLE CHANNEL-BASED STATION ENABLEMENT AND DE-ENABLEMENT IN TELEVISION BAND WHITE SPACES - A method and system for wireless communication in a TV band white space spectrum is provided. A wireless master device keeps track of available wireless communication channels in a white space spectrum. The master device performs an enablement process for enabling a corresponding client device to transmit on a wireless channel. During the enablement process, the master device allows the client device to select a wireless channel for communication from among: a specific operating wireless channel, a subset of the available wireless channels, and all available wireless channels. | 05-19-2011 |
20110310253 | METHOD AND SYSTEM FOR SELF-ENABLING PORTABLE TELEVISION BAND DEVICES - Embodiments of the invention provide a method and system for determining wireless channel interference in a television (TV) band white space spectrum. Upon sensing a signal on a wireless channel from a wireless white space device that transmits a unique device identifier, interference by the wireless white space device on the wireless channel is determined. A report of the channel interference by the wireless white space device is generated and may be utilized to cease the interference. | 12-22-2011 |
