Patent number: 9008734Abstract: A wireless communication device is disclosed that is capable of reduced power consumption. Uplink and downlink sub-frames in a WiMAX, 802.16m or LTE environment often include several vacant symbols during which power-hungry hardware and software components need not operate at full power. By analyzing a physical layer beacon and control information of a received signal, the specific locations of data bursts can be determined, as well as periods of needed operation of a receiver module to effectively decode those data bursts. The receiver module can otherwise be controlled to operate in a LOW power state during remaining periods of vacant time, thereby conserving power consumption and extending battery life.Type: GrantFiled: December 1, 2011Date of Patent: April 14, 2015Assignee: Broadcom CorporationInventors: Shashidhar Vummintala, Gowrisankar Somichetty, Sriram Rajagopal, Sindhu Verma, Manish Airy, Hariprasad Gangadharan, Ramasamy Palanisamy Pugazhanthi, Felix Varghese, Erik Stauffer

Patent number: 8954230Abstract: In telematics device mounted to a vehicle, an auxiliary processor detects an interrupt from an accelerometer and forwards the interrupt to a main processor—the interrupt wakes up the processor from a sleep mode. The main processor may then compare vehicle voltage and/or a value for a speed parameter to predetermined criteria to determine whether the interrupt was a false positive or if the accelerometer missed a detection of a user cranking up the vehicle. The main processor may also enter a conditional state if monitored information meets a minimum threshold. During the conditional state, the processor may operate according to rules for a current operational state and also according to rules for a changed state. The threshold for deeming a changed operational state is higher than for entering a conditional state to evaluate whether a change of operational state (i.e., on to off, or off to on) occurred.Type: GrantFiled: February 20, 2014Date of Patent: February 10, 2015Assignee: HTI IP, LLCInventors: Deep Kalinadhabhotla, Ivan Neflali Cardenas Perez, Bruce Lighter

Patent number: 8929878Abstract: Transaction identifiers for transactions are managed to mitigate potential mismatches that may occur in the event a message associated with the transaction is not delivered to the intended destination. For example, in the event an access terminal accepts a bearer context request, the access terminal may not immediately release the transaction identifier associated with that transaction. In this way, in the event the access terminal receives a second bearer context request associated with that same transaction identifier (e.g., due to the accept message not reaching the network), the access terminal may send a second accept message in response to the second bearer context request.Type: GrantFiled: May 18, 2010Date of Patent: January 6, 2015Assignee: QUALCOMM IncorporatedInventors: Miguel Griot, Osok Song, Nagaraja Kumar Maganti

Patent number: 8913961Abstract: Systems and methods are disclosed which relate to mitigating the detrimental effects of interference to electronic devices from mobile telephones utilizing any form of time-domain multiplexing technology. A wireless transmitter inside the mobile telephone broadcasts a warning transmission which can be received by affected devices. Once the warning transmission is received by an affected device, the device activates a blanking circuit comprising an actuator and a switch or switches. The switches open for the duration of the interference so that the user does not receive undesired output such as: noise through a speaker, noise through a microphone, or other interference with electrical signals.Type: GrantFiled: November 13, 2008Date of Patent: December 16, 2014Assignee: AT&T Mobility II LLCInventors: Scott Dale Prather, Cameron Kelly Coursey, Herman Chien

Patent number: 8909159Abstract: Embodiments of a system and methodology are disclosed for aperiodic (i.e., non-periodic) feedback of channel-side information, such as channel rank information, to a base station by having the receiver/UE initiate the feedback instead of using a scheduled feedback approach. The autonomous feedback of channel-side information may use one of several different types of physical channel structures for uplink scheduling requests, such as those being discussed for inclusion in the emerging LTE platform standard.Type: GrantFiled: October 22, 2012Date of Patent: December 9, 2014Assignee: Apple Inc.Inventors: Jayesh H. Kotecha, James W. McCoy

Patent number: 8897828Abstract: Power control in a wireless network is disclosed. Transmit power control (TPC) commands may be accumulated by a user equipment (UE). If accumulation is enabled, the UE may receive on a single physical channel an allocation of a scheduled uplink resource and a TPC command. The TPC command may be accumulated with other received TPC commands. A transmit power for an uplink communication based on both the path loss and the accumulated TPC commands may then be calculated by the UE. If accumulation is not enabled, the UE may receive an allocation of a scheduled uplink resource to transmit data at a calculated power level.Type: GrantFiled: August 12, 2004Date of Patent: November 25, 2014Assignee: Intellectual Ventures Holding 81 LLCInventor: Nicholas William Anderson

Patent number: 8897712Abstract: Some demonstrative embodiments include devices, systems and/or methods of wireless communication via multiple antenna assemblies. For example, a device may include a wireless communication unit to transmit and receive signals via one or more quasi-omnidirectional antenna assemblies, wherein the wireless communication unit is to transmit, via each quasi-omnidirectional antenna assembly, a plurality of first transmissions, to receive, in response to the first transmissions, a plurality of second transmissions from another device via one or more of the quasi-omnidirectional antenna assemblies, and, based on the second transmissions, to select at least one selected transmit antenna assembly for transmitting to the other device and a selected receive antenna assembly for receiving transmissions from the other device. Other embodiments are described and claimed.Type: GrantFiled: September 15, 2013Date of Patent: November 25, 2014Assignee: Intel CorporationInventors: Menashe Sofer, Assaf Kasher

Patent number: 8891598Abstract: A communication device operating in time division duplex (TDD) mode using multiple antennas is provided herein. The communication device uses receive channel estimation measurements to perform transmit beamforming and multiple input multiple output (MIMO) transmission, based on self-calibration of the various up/down paths via a method of transmission and reception between its own antennas, thus achieving reciprocity mapping between up and down links. Either user equipment (UE) or a base station may routinely perform this self-calibration to obtain the most current correction factor for the channel reciprocity to reflect the most current operating conditions present during TDD MIMO operation.Type: GrantFiled: December 17, 2013Date of Patent: November 18, 2014Assignee: Magnolia Broadband Inc.Inventors: Sherwin J.

This is accomplished by utilizing cell and mobile phones capable of establishing persistent Internet connections. A software application is provided for the mobile phone that receives inputs entered by a user on the mobile phone's keypad and translates the inputs into commands that are recognized by a multimedia device. For example, the multimedia device may be a television, set top box, or a digital video recorder such as a Tivo or ReplayTV. The software application transmits the data input by the user to the device, either directly, or through at least one central server.
