Patent number: 8830929Abstract: A wireless combination device includes a first wireless transceiver configured for communication via a first wireless network over a first band, and a second wireless transceiver configured for communication via a second wireless network over a second band that overlaps the second band. The combination device includes a medium allocation scheduler coupled to the first wireless transceiver and second wireless transceiver for implementing spaced-mode operation that intentionally inserts idle gaps in transmissions via the second wireless network when triggered by the presence of at least one spaced-mode triggering condition. The idle gaps allow wireless transmissions via the first wireless network to be received by the combination device with higher probability, and without the need for clear to send (C2S) protection.Type: GrantFiled: June 15, 2011Date of Patent: September 9, 2014Assignee: Texas Instruments IncorporatedInventors: Yanjun Sun, Ariton E.

Patent number: 8830818Abstract: System(s) and method(s) are provided for forward handover under radio link failure. A configurable criterion for radio link failure (RLF) is established through a reference threshold for a channel quality metric; the threshold (CQITH) can be determined at least on a quality-of-service basis or a per-terminal basis. A low-overhead indication of RLF is conveyed as a NULL CQI when the channel quality metric is below threshold. Onset of RLF triggers preparation of forward handover (FHO) at a terminal within a predetermined timer, during which normal service can resume if link quality recovers above CQITH. Forward handover is pursued once timer elapses. Preparation at the terminal can be complemented by preparation implemented in advanced to RLF condition, in accordance to a disparate threshold applied to terminal's measurements. Preparation of FHO includes backhaul exchange of operational information like buffered data, and context.Type: GrantFiled: June 6, 2008Date of Patent: September 9, 2014Assignee: QUALCOMM IncorporatedInventor: Aleksandar Damnjanovic

Patent number: 8830906Abstract: A system includes a networking enabled system and a packet radio system. The packet radio system includes a wireless interface and a packet interface. The packet interface includes at least two queues, each queue configured to store a certain class of packets of Ethernet. A cable is operative to transport the packets from the networking enabled system to the packet interface using Ethernet signaling. The packet interface is configured to ascertain from time to time the rate at which the packets are sent from the queues over the wireless interface, and according to the rate, indicate dynamically to the network enabled system the classes of packets for which packets are to be sent over the cable for storage in the appropriate queues. The network enabled system is configured to send, over the cable, packets of classes indicated by the packet interface, while holding back other packets.Type: GrantFiled: August 31, 2010Date of Patent: September 9, 2014Assignee: Siklu Communication Ltd.Inventors: Leonid Shousterman, Itzhak Ben-Bassat, Yigal Leiba

The backhaul subframe includes two slots among. Among single carrier frequency division multiple access (SC-FDMA) symbols that constitute the backhaul subframe, an orthogonal cover (OC) sequence is applied to the SC-FDMA symbol which the modulation symbol has been mapped into, and later the backhaul subframe is transmitted. The generated modulation symbol is mapped according to the same pattern as the two slots.Type: GrantFiled: July 29, 2010Date of Patent: July 29, 2014Assignee: LG Electronics Inc.Inventors: Min Seok Noh, Sung Ho Moon, Kyu Jin Park, Jae Hoon Chung

Patent number: 8780686Abstract: The memory storage, transmission and processing demands of a vectored DSL system are reduced by sampling a subset of DSL tones in the DSL tone range used in the vectored system. This data is smoothed (denoised) to further reduce the data's size, sacrificing some fidelity or precision as a result. Finally, lossless entropy coding or the like is performed to encode the FEXT cancellation data for storage and use. The resulting data is less likely to cause transmission bottlenecks in the vectored system, can be stored and used more efficiently for both on-chip and off-chip vectoring implementations, and can be readily updated in various ways.Type: GrantFiled: July 22, 2011Date of Patent: July 15, 2014Inventors: Nicholas P.

Patent number: 8760998Abstract: Ambiguity (e.g., confusion) associated with access point identifiers may be resolved by querying candidate target access points and/or by using historical records indicative of one or more access points that the access point has previously accessed. For example, messages may be sent to access points that are assigned the same identifier to cause the access points to monitor for a signal from an access terminal that received the identifier from a target access point. The target access point may then be identified based on any responses that indicate that a signal was received from the access terminal. In some aspects the access points subject to being queried may be selected using a tiered priority. In addition, it may be determined based on prior handoffs of a given access terminal that when that access terminal reports a given identifier, the access terminal usually ends up being handed-off to a particular access point.Type: GrantFiled: February 4, 2013Date of Patent: June 24, 2014Assignee: QUALCOMM IncorporatedInventors: Aleksandar M. Gogic, Chandrasekhar T. Sundarraman, Sanjiv Nanda, Peerapol Tinnakornsrisuphap, Rajarshi Gupta

Patent number: 8755305Abstract: A wireless networking device adapter for provisioning a wireless network using new or existing track lighting. The adapter securely engages the track light channel and supports a commercially available wireless access point (WAP) device. A lock mechanism on the adapter prevents unexpected disengagement of the adapter from the track light channel, yet allows for operator removal. A power converter within the adapter powers the WAP device from the electrical power provided by the track light channel. Multiple adapters communicate to form a mesh network to improve wireless network fault tolerance, or may operate in a repeater mode configuration or some combination.Type: GrantFiled: July 10, 2012Date of Patent: June 17, 2014Inventors: Girish Altekar, Murray Freeman
