  • Patent number: 8849336
    Abstract: A femtocell power control module is operative to: obtain at least one uplink communication characteristic associated with the uplink signals 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.

  • Patent number: 8626186
    Abstract: Control unit within a femtocell base station is arranged to detect a transmission collision situation and resolves it by adjusting the timing of the transmission signal and consequently the frame position gradually over time. The adjustment (or shift) is performed in a slow enough rate such that the User Equipments currently connected (camped) to the femtocell base station remain connected. Additionally, a method is also provided. The method comprises: detecting neighboring base stations; detecting frame boundaries of the transmitting signal of each detected neighboring base station; calculating optimal transmit position; setting transmit position to calculated optimal transmit position; and maintaining optimal transmit position by gradually adjusting transmit position over time.

  • Patent number: 8559345
    Abstract: 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.

  • Patent number: 8522065
    Abstract: 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).
