Patent number: 11856392Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.Type: GrantFiled: June 1, 2021Date of Patent: December 26, 2023Assignee: QUALCOMM IncorporatedInventors: Steven Cheng, Remi Gurski, Kuo-Chun Lee, Tom Chin, Guangming Shi

Patent number: 8787433Abstract: A modem (for example, a modem within a cellular telephone) includes a plurality of Wireless Communication System Modem Sub-Circuits (WCSMSCs). Each WCSMSC receives a control signal generated by a corresponding one of a plurality of programmable timers. Each timer receives the same sequence of count values from a wall clock counter. A processor that controls overall modem operation can program a timer to generate a control pulse at a particular count time of the wall clock counter. The processor can also program a timer to generate a periodic control signal. The control signals output from the timers orchestrate when the various WCSMSCs start operating in the processing of a frame. By virtue of the programmability of the timers, the wall clock timer system is programmable to generate customized control signals such that frames of new and different protocols having arbitrary frame structures can be processed by the same modem/timer system.Type: GrantFiled: October 30, 2008Date of Patent: July 22, 2014Assignee: Qualcomm IncorporatedInventors: Arunava Chaudhuri, Iwen Yao, Jeremy H.

Patent number: 8726138Abstract: A method and apparatus for decoding of tailbiting convolutional codes (TBCC) are disclosed. The proposed modified maximum-likelihood TBCC decoding technique preserves error correction performance of optimal maximum-likelihood based TBCC decoding, while the computational complexity is substantially decreased since a reduced number of decoding states has been evaluated. Compare to other sub-optimal TBCC decoding algorithms, modified maximum-likelihood TBCC decoding achieves improved packet error rate performance with similar computational complexity.Type: GrantFiled: October 13, 2008Date of Patent: May 13, 2014Assignee: QUALCOMM IncorporatedInventors: Ju Won Park, Brian Banister, Je Woo Kim, Jong Hyeon Park, Matthias Brehler, Remi Gurski, Tae Chang

Patent number: 8458380Abstract: A flexible and reconfigurable digital system (for example, a wireless modem) includes a set of sub-circuits. Each sub-circuit includes a task manager and an amount of configurable hardware circuitry for performing a type of operation on a data stream. The task manager of a sub-circuit can configure and control the configurable hardware of the sub-circuit. A central processor configures and orchestrates operation of the sub-circuits by maintaining a set of task lists in a tightly coupled memory. Each task list includes task instructions for a corresponding sub-circuit. The task manager of a sub-circuit reads task instructions from its task list and controls its associated hardware circuitry as directed by the instructions. A timestamp task instruction and a push task instruction and the task list architecture allow modem sub-circuits to be easily reconfigured to operate in accordance with either a first air interface standard or a second air interface standard.Type: GrantFiled: March 2, 2009Date of Patent: June 4, 2013Assignee: Qualcomm IncorporatedInventors: Arunava Chaudhuri, Iwen Yao, Jeremy H.

Patent number: 8281111Abstract: A system and method to execute a linear feedback-shift instruction is disclosed. In a particular embodiment the method includes executing an instruction at a processor by receiving source data and executing a bitwise logical operation on the source data and on reference data to generate intermediate data. The method further includes determining a parity value of the intermediate data, shifting the source data, and entering the parity value of the intermediate data into a data field of the shifted source data to produce resultant data.Type: GrantFiled: September 23, 2008Date of Patent: October 2, 2012Assignee: QUALCOMM IncorporatedInventors: Erich Plondke, Lucian Codrescu, Remi Gurski, Shankar Krithivasan

Patent number: 7085295Abstract: Techniques to search for pilots over code space in a CDMA system. In one aspect, the pilot search is performed using a number of substages, and the search windows for each substage are selected such that the relevant code space is searched while reducing search time. In one specific implementation, two substages are used to search for pilots. The detect substage searches through (e.g., fixed-size) search windows to detect for peaks in the received signal. The dwell substage then searches through (e.g., variable-size) search windows to re-evaluate the detected peaks and remove noise peaks. The dwell windows may be formed such that a code space as small as possible is searched (to reduce search time) but large enough to account for possible drift in the detected peaks. Variable number of peaks may be provided by the dwell substage for the variable-size dwell windows.Type: GrantFiled: October 25, 2001Date of Patent: August 1, 2006Assignee: Qualcomm IncorporatedInventors: Remi Gurski, Serguei A.
