20150350934 | UPLINK TIMING ADJUSTMENT IN MULTI-SIM/MULTI-STANDBY DEVICES - A method/apparatus for wireless communication for a multi SIM/multi standby device having a single radio stores an uplink transmission timing of a first radio access technology (RAT) and a first path loss measurement before tuning away from the first RAT to perform an activity with a second RAT. A second path loss of the first RAT is measured after tuning back, and the second path loss measurement is compared to the first path loss measurement. The uplink transmission timing is adjusted based at least in part on the comparison. | 12-03-2015 |
20150302195 | HARDWARE-BASED STACK CONTROL INFORMATION PROTECTION - Techniques for protecting contents of a stack associated with a processor are provided. The techniques include a method including receiving a store instruction from a software program being executed by the processor, the store instruction including control information associated with a subroutine, altering the control information to generate secured control information responsive to receiving the store instruction from the software program, storing the secured control information on the stack, receiving a load instruction from the software program; and responsive to receiving the load instruction from the software program, loading the secured control information from the stack, altering the secured control information to recover the control information, and returning the control information to the software program. | 10-22-2015 |
20150063718 | TECHNIQUES FOR ENHANCING LOW-LIGHT IMAGES - Techniques are described for enhancing quality of a first image that is captured in a low-light environment. In one embodiment, a second image is generated by brightening a plurality of pixels in the first image based on a predefined criteria. A third image is generated using an edge-preserving noise reduction algorithm based on the second image. Further, a composite image is generated by obtaining a weighted average of the first image and the third image. The techniques described herein can be applied to an image and/or to each frame of a video that is captured in low-light environments. | 03-05-2015 |
20140301467 | ADVANCED MERGE MODE FOR THREE-DIMENSIONAL (3D) VIDEO CODING - As part of a video encoding process or a video decoding process, a video coder may determine a first available disparity motion vector among spatial neighboring blocks of a current block of the video data. Furthermore, the video coder may shift a horizontal component of the first available disparity motion vector to derive a shifted disparity motion vector candidate (DSMV). The video coder may add the DSMV into a merge candidate list. | 10-09-2014 |
20140204881 | Systems, Apparatus and Methods for Facilitating Frequency Reuse for Downlink Control Channels - Systems and methods for frequency reuse on downlink control channels (DLCCs) are provided. One method can include determining a first number of symbols to support transmission of control information on a DLCC, and configuring a second number of symbols for transmission of the control information on the DLCC, wherein the second number of symbols is greater than the first number of symbols. The method can also include assigning a number of DLCCs based on the second number of symbols, and transmitting control information over an assigned number of DLCCs to achieve an effective reuse factor less than one. Another method can include identifying fractions of bandwidth in a system having cells, and allocating at least one of the cells to at least one of the fractions of bandwidth in a system. Resource element groups allocated to the fractions of bandwidth can be coordinated across cells to provide frequency reuse. | 07-24-2014 |
20140185496 | LOW LATENCY ARQ/HARQ OPERATING IN CARRIER AGGREGATION FOR BACKHAUL LINK - Described embodiments reduce ARQ/HARQ latency using carrier aggregation and cross-carrier ARQ/HARQ signaling. In embodiments, a wireless backhaul transmission link uses multiple paired carriers with complementary TDD frame timing. In embodiments, backhaul traffic subframes are protected using FEC and/or CRC encoding and ACK/NACK information is generated based on decoding and computing the FEC and/or CRC information for the subframes. The ACK/NACK information may be transmitted on the paired carrier. In embodiments, cross-carrier ARQ/HARQ signaling may reduce ARQ/HARQ latency to less than two TDD subframes. | 07-03-2014 |
20140172945 | LOADING A RE-DIRECTED WEB PAGE ON A WEB BROWSER OF A CLIENT DEVICE IN A COMMUNICATIONS SYSTEM - In an embodiment, a client device transmits a request for an initial web page to a proxy server. The proxy server requests the initial web page on behalf of the client device in response to the client device's request. The proxy server then executes a web page redirection procedure that is independent of interaction with the client device and results in the proxy server obtaining web page content. The proxy server delivers the web page content to a proxy client application on the client device along with instructions for simulating, on the client device, the web page redirection procedure between the proxy client application and a mobile web browser on the client device. The proxy client application on the client device then simulates the web page redirection procedure that occurred at the proxy server as instructed. | 06-19-2014 |
20130176774 | SYSTEM AND METHOD OF REFERENCE CELL TESTING - Systems and methods of testing a reference cell in a memory array are disclosed. In a particular embodiment, a method includes coupling a first reference cell of a first reference cell pair of a memory array to a first input of a first sense amplifier of the memory array. The method also includes providing a reference signal to a second input of the first sense amplifier. The reference signal is associated with a second reference cell pair of the memory array. | 07-11-2013 |
20120046045 | METHODS AND APPARATUSES FOR USE IN ESTIMATING A LOCATION OF A MOBILE DEVICE WITHIN A STRUCTURE - Methods and apparatuses are provided that may be implemented in a mobile device to determine two or more variations between a baseline probability distribution and two or more probability distributions for signals received from two or more sets of transmitters assigned to two or more regions of a structure. The methods and apparatuses may be further implemented to determine whether the mobile device is located in at least one of the two or more regions based, at least in part, on a comparison of the two or more determined variations. | 02-23-2012 |
20100316122 | MULTIVIEW VIDEO CODING OVER MPEG-2 SYSTEMS - A multiplexer may produce an MPEG-2 (Motion Picture Experts Group) System standard bitstream comprising views with nonconsecutive view order indexes. In one example, an apparatus comprises a video encoder that encodes a plurality of views of a scene, a multiplexer that constructs a data structure for signaling that a corresponding MPEG-2 (Motion Picture Experts Group) System standard bitstream comprises a first view of the plurality of views of the scene associated with a first view order index and a second view of the plurality of views of the scene associated with a second view order index, wherein the first view order index and the second view order index are non-consecutive, and an output interface that outputs the data structure. | 12-16-2010 |
