H04J 3/06

US Classification:

370503, 370256, 370521

Abstract:

A system and method for synchronously transmitting media data is described. Synchronization data may be transmitted by a cycle master for receipt by one or more cycle slaves. A cycle slave may update an internal state based on the synchronization data received from the cycle master. The cycle master may transmit media data to multiple cycle slaves. The media data output by the cycle slaves may be determined, in part, by the internal state. In one embodiment, the media data may determine which cycle slave receives particular media data.

QUALCOMM Incorporated - San Diego CA

International Classification:

H04J 1/00

US Classification:

370227, 370230, 370252, 370401

Abstract:

An access point and an integrated circuit including processor are disclosed operating the transceiver to create a station link table for a link to the station, a channel quality estimate of the home channel, an other channel quality sample log for at least one other channel and an other channel quality estimate based upon the other channel sample log. The processor using the station link table and the channel quality estimate of the home channel to determine if the access point has difficulty meeting the minimum required bandwidth and responds to difficulty by determining if the other channel can meet the minimum required bandwidth and schedule changing the home channel to the other channel.

Steven J. Kuhn - Santa Clara CA, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

G01R 31/08
H04B 7/00

US Classification:

3702301, 370310, 37039521, 37039542

Abstract:

A device or chip can be designed and/or programmed to select different sets of wireless link rate determination operations that account for different degrees of presentation time sensitivity that correspond to different classes of traffic. The device or chip can infer or explicitly determine presentation time sensitivity based, at least in part, on traffic class. The selected wireless link rate operations select link rates for the different classes of traffic. A first set of the wireless link rate determination operations can choose a smoother and more stable wireless link rate for the wireless traffic class that conveys presentation time sensitive content. A second of the wireless link rate determination operations can choose a fastest possible wireless link rate, which may be more susceptible to jitter and delay, for a traffic class that is less sensitive.

Appl. No.:

13/090784

Inventors:

Roshan R. Baliga - Bangalore, IN
Steven J. Kuhn - Santa Clara CA, US

Assignee:

Atheros Communications, Inc. - San Jose CA

International Classification:

G06F 15/173
G06F 15/16

US Classification:

709209, 709239

Abstract:

A forwarding device can establish a communication link with both a source device and a destination device to extend the communication range of the source device by forwarding data from the source device to the destination device. A coordinating device can be configured to identify a forwarding client through which to communicate with a client station that is inaccessible to the coordinating device via a direct communication link, based on the throughput achieved on communication links between the coordinating device, the inaccessible client, and accessible clients. The throughput achieved on the communication links can be determined by exchanging training packets, receiving acknowledgement messages in response to the training packets, and subsequently analyzing the received acknowledgement messages. Based on the calculated throughputs, one of the accessible clients can be designated as the forwarding client with respect to the coordinating device and the inaccessible client.

QUALCOMM ATHEROS, INC. - San Jose CA

International Classification:

H04L 12/56

US Classification:

370389

Abstract:

A path selection unit selects a network communication path from a plurality of available network communication paths for transmitting data from a hybrid network device to a destination network device. A packet transmit unit determines path connection characteristics associated with the selected network communication path. The packet transmit unit generates a hybrid network packet for transmitting the data to the destination network device based, at least in part, on the path connection characteristics associated with the selected network communication path. The packet transmit unit transmits the hybrid network packet to the destination network device via the selected network communication path.

US Classification:

370252, 370336

Abstract:

Described embodiments are directed to systems, methods, and apparatuses for dynamically scheduling channel dwell times across two or more channels across a single radio using Multi-Channel Concurrency. Communications may be transmitted and/or received over a first channel of the radio during a first dwell time of a dwell period and over a second channel of the radio during a second dwell time of the dwell period. Some embodiments include adjusting the dwell period and/or dwell time spent actively transmitting or receiving on two or more channels based on measured channel utilization metrics, to drive toward a balanced utilization across the two or more channels. Other embodiments include adjusting the dwell period and/or dwell time of multiple channels based on latency information and/or priority information of at least one of the channels.

International Classification:

H04L 29/06

US Classification:

709231

Abstract:

Dynamic control by a source device of sink buffer size for audio and/or video streaming over an error-prone channel. The sink buffer size may be determined based on a type of application for a media stream being transmitted from the source device to the sink device for presentation. The techniques may select a buffer size that is smaller for gaming applications, larger for interactive media applications, and even larger for non-interactive media types. The techniques adjust the time delta between a shared clock reference and time reference values of a transport stream that are used by the sink device to determine decoding or presenting of media frames of the transport stream relative to a shared clock reference. In addition, the techniques may account for transceiver latency at the source device due to scanning or multiple concurrent connections.
