摘要： Techniques are provided to control the transmit power for data transmission on multiple transport channels having different signal quality (SIR) targets. A single SIR target is maintained for all transport channels, and this SIR target is adjusted based only on active transport channels. For each update interval, a data processor processes at least one data block received in the current update interval on at least one of the transport channels and provides the status of each received data block. A controller increases the SIR target based on an up step if any received data block is erased and decreases the SIR target based on a down step if all received data blocks are good. If any received data block is erased, the down step used to adjust the SIR target may be set to the smallest down step size required by all transport channels with erased data blocks.

摘要： A wireless communication device performance, such as standby time, is improved by adaptively allocating surplus system resources to change quick paging channel parameters at the system, such a system being for example, a base station. Adaptively adjusting the quick paging channel parameters allows available base station resources to be allocated to the quick paging channel, thereby enabling the wireless communication device to demodulate the quick paging channel more reliably. Parameters such as the number of quick paging channels, the data rate used by the paging channel, and the quick paging channel transmit power level are weighed and adjusted.

摘要： A phase lock loop apparatus and method is disclosed. A typical apparatus includes a demodulator receiving a phase error signal from a comparator at a chip rate and providing a phase error update over a symbol period from the phase error signal wherein the chip rate is higher than the symbol rate. A phase discriminator produces a phase error output at the symbol rate from the phase error update based upon a signal modulation type. A loop filter produces one or more phase estimate parameters at a symbol rate from the phase error output and a numerically controlled oscillator (NCO) extrapolates a phase reference at a chip rate from the one or more phase estimate parameters at a symbol rate. The comparator produces the phase error signal to the demodulator based upon the phase reference and an incoming signal.

摘要： A wireless device achieves good performance using a crystal oscillator that is not compensated for temperature. The crystal oscillator provides a reference signal having a temperature dependent frequency error. A control unit estimates the frequency error (e.g., based on a received pilot) and provides a frequency error estimate. A clock generator generates a digital clock, which tracks chip timing, based on the reference signal and the frequency error estimate. A receiver frequency downconverts an input RF signal with a receive LO signal having the frequency error and provides an analog baseband signal. An ADC digitizes the analog baseband signal based on a sampling clock having the frequency error and provides ADC samples. A re-clocking circuit re-clocks the ADC samples based on a digital clock and provides data samples. A digital rotator frequency translates the data samples based on the frequency error estimate and provides frequency-translated samples centered near DC.
