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.

Femtocell handset assisted clock correction

A method for managing power control of enhanced dedicated channel (E-DCH) uplink (UL) channels of at least one user equipment (UE) that is located on a femtocell base station (FBS), is provided herein. The method includes calculating, for the UE, a maximum dedicated physical control channel (DPCCH) power level. The method also includes lower, by the FBS, a DPCCH power level for the UE when the actual DPCCH power level is exceeding the maximum DPCCH power level for the UE. The lowering of the DPCCH power level is independent of a signal-to-interference (SIR) target for the FBS.

Power management of user equipment located on a femtocell base station

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.

Dynamically controlling a Femtocell base station downlink range for interference avoidance

Embodiments of the present invention provide a system, method, and apparatus of adjusting a wireless communication signal. In some demonstrative embodiments the method may include, for example, allocating a plurality of spectral components to an adjustment signal based on a spectral range of the wireless communication signal to be adjusted by the adjustment signal, wherein one or more of the spectral components are included in the spectral range. Other embodiments are described and claimed.

System, method and device of adjusting a wireless communication signal

Briefly, a wireless system and a method of dynamically allocating one or more medium access blocks of a first communication network within one or more medium access blocks of a second wireless communication network, wherein the first wireless communication network operates according to a first wireless medium access scheme and the second wireless communication network operates according to a second wireless medium access scheme.

System, apparatus and method of allocating medium access blocks

Embodiments of a method for acquisition of GPS signals and a GPS receiver with sample time error and frequency offset compensation are generally described herein. Other embodiments may be described and claimed. In some embodiments, GPS signals are resampled at a plurality of sample rates for each of a plurality of predetermined frequency offsets to compensate for sample time error and frequency offset of a crystal oscillator. The resampled GPS signals may be cross correlated for each of the predetermined frequency offsets. In some embodiments, the sample time error and the frequency offset of the crystal oscillator may substantially exceed a time and frequency drift of reference clocks on GPS satellites.

Some embodiments of the invention provide devices, systems and methods of point to multipoint communication. For example, an apparatus in accordance with an embodiment of the invention includes a resource allocator to allocate a wireless communication channel resource to one or more stations of a wireless communication system based on a net benefit function that takes into account an overhead incurred by controlling the allocation of said channel resource.

Device, system and method of point to multipoint communication

Briefly, a wireless communication system having two or more wireless communication devices. The wireless communication device includes a transmitter to transmit a signal over a wireless channel and to determine a bandwidth of the wireless channel and a power level of the signal based on a quality value of the wireless channel. A method of varying the bandwidth of the wireless channel is also provided.

System, apparatus and method of varying channel bandwidth

A method of apparatus to free at least a portion of memory space of a memory device from at least a portion of a stored data block, wherein the freeing is based on the block sequence number of the stored data block and/or a quality indicator value related to at least a portion of the stored data block. Other embodiments may be described and claimed.

Method and apparatus for freeing memory

A method and apparatus to free at least a portion of memory space of a memory device from at least a portion of a stored data block, wherein the freeing is based on the block sequence number of the stored data block and a quality indicator value related to at least a portion of the stored data block. The apparatus may include a receiver to receive at least the portion of the data block transmitted according to an error correction scheme.

A receiver is to receive an encoded data block that was encoded using a convolutional encoder and includes source bits and error detection bits. The receiver may include a Viterbi decoder, a de-mapper and an error detection unit. The error detection unit is to determine whether an error correction capability of the Viterbi decoder is sufficient to recover the source bits from the encoded data block. The Viterbi decoder is to decode the encoded data block only if the encoded data block is not free of errors and if the error correction capability of the Viterbi decoder is sufficient to recover the source bits from the encoded data block.

System and method for error detection in encoded digital data

An apparatus and a communication device including a turbo decoder to decode a block of encoded data bits that includes information bits and error detection code bits. The turbo decoder is able to produce a decoded block which includes decoded information bits and decoded error detection code bits. The Turbo decoder is able to determine from the decoded error detection code bits and calculated error detection code bits possible error patterns of the error detection code bits and is able to generate from the possible error patterns and/or from the error detection code bits reliability metrics.

Iterative decoding process

Method and apparatus of memory management

Decoding an encoded block of data is accomplished by partitioning the block into a first and a second sub-block and performing forward and backward iterative calculations on the sub-blocks in separate processes. Based on results of the iterative calculations an output matrix may be calculated for each sub-block. The outputs may be combined.
