| 20110194534 | ESTABLISHING COLOCATED SECOND CELL USING A SECOND SCRAMBLING CODE BY A FEMTO BASE STATION - In a cellular communications network, it may be desirable for a large number of basestations to share one or a small number of scrambling codes. When a basestation identifies a desired scrambling code, which is also being used by another nearby basestation, steps are taken such that a location area update is triggered whenever a mobile communications device moves from a coverage area of the nearby basestation into a coverage area of said basestation. Further, the basestation establishes a first cell, using the desired scrambling code, and also establishes a second cell also served by the basestation, using a second scrambling code. By ensuring that mobile devices are preferentially served by the second cell, the possibility of interference with the nearby basestation is reduced. | 08-11-2011 |
| 20110105110 | DYNAMICALLY CONTROLLING A FEMTOCELL BASE STATION DOWNLINK RANGE FOR INTERFERENCE AVOIDANCE - A femtocell power control module is operative to: obtain at least one uplink communication characteristic associated with the uplink signal transmitted by the at least one cellular communication device and received by the femtocell base station; estimate, from the obtained uplink communication characteristic, the power level of the downlink signals transmitted by the femtocell base station, as received by the at least one cellular communication device; if the estimated power level of the downlink signals transmitted by the femtocell base station as received by the at least one cellular communication device exceeds a predefined threshold power level, reduce the power level of the downlink signals transmitted by the femtocell base station to a reduced power level. | 05-05-2011 |
| 20110060935 | Generating A Random Number In An Existing System On Chip - A system for generating a true random number and implemented within an existing System on Chip (SoC) is provided herein. The system includes one or more sub circuitry synchronous modules configured to operate in a specified nominal clock rate, wherein each sub circuitry synchronous modules yields expected deterministic results when operating in its nominal clock rate; and a control module configured to clock the one or more sub circuitry synchronous modules each in a clock rate higher than its respective the nominal clock rate and beyond a specified value, to yield a non deterministic behavior of the one or more sub circuitry synchronous modules, resulting in one or more random signals, wherein the system is implemented within an existing system on chip (SOC). | 03-10-2011 |
| 20100273474 | FEMTOCELL HANDSET ASSISTED CLOCK CORRECTION - A method of improving frequency accuracy of a clock unit adapted to clock a femtocell local cellular communication home base station is provided. The method comprising: providing a local cellular communication home base station having an oscillator adapted to operate as a clock therein, wherein at least one cellular communication device is camped thereto, and wherein the at least one camped cellular communication device is further in communication with at least one neighboring cellular communication base station which is associated with an oscillator adapted to operate as a clock therein; periodically applying a derivative operator over periodically obtained local communication parameters and periodically obtained neighboring communication parameters thereby generating derivative communication parameters over time; and correcting the accuracy of the frequency of the clock in the femtocell local cellular communication home base station using the derivative communication parameters over time. | 10-28-2010 |
