摘要： An automatic frequency control (AFC) system in an electronic device is operated by using an AFC-algorithm component to determine a frequency error corresponding to a difference between a frequency of a signal output from a signal generator and a received signal frequency. The frequency error determined by the AFC-algorithm component is multiplied by a scaling factor, which is set to zero after an adjustment has been made to change a frequency of the signal output from the signal generator. The scaling factor is increased from zero to one over time. The scaled frequency error is used to determine whether to adjust the frequency of the signal output from the signal generator.

摘要： Methods and apparatus are described for estimating a path-loss difference between uplink and downlink communications at a first node communicating with a second node in a communication system. A quantity of access request preambles transmitted by the first node to the second node before an acknowledgement from the second node of successful receipt of a preamble is received at the first node is determined. A difference between an uplink path-loss attributed to communications from the first node to the second node and a downlink path-loss attributed to communications to the first node from the second node is estimated based on the transmitted preamble quantity determination. Once the path-loss difference is estimated, the estimate can be used for many purposes, such as to determine a transmission power of the first node.

摘要： Methods, receivers, and computer program products for defining asymmetric decision regions of a symbol space to interpret transmitted power control commands are disclosed. A method of determining transmitted power control commands at a receiver can include defining a first decision region of a symbol space associated with a first power control command at the receiver and a second decision region of the symbol space associated with a second power control command at the receiver where the first and second regions are asymmetric with one another. Methods of determining a transmitted power control command during soft handover mode in a wideband code division multiple access communications system are also discussed wherein a first determination of a combined power control command received from a plurality of transmitters can be combined with a second determination of the combined power control command received from the plurality of transmitters to provide a combined power control command.

摘要： Methods and devices for detecting a symbol in a radio channel and for cell identification are disclosed. A signal is received from the radio channel and the signal is filtered by a filter being responsive to the symbol thereby establishing a first signal. A second signal dependent on the noise floor of the received signal is established—whereby a time interval expected to include multi-path components being excluded or suppressed. A third signal being the ratio between the first signal and the noise floor is established, and the presence of the symbol is detected by detecting a peak in the third signal.

摘要： The automatic frequency correction value applied by a receiver is altered to minimize long-term drift of a path delay profile. In one embodiment, the phase or timing error resulting from constant frequency corrections is accumulated, and an estimated frequency correction value is selectively quantized into an actual frequency correction value in response to the accumulated phase/timing error. The quantized value above or below the estimate is selected to minimize the accumulated phase/timing error that gives rise to path delay profile drift. In another embodiment, a timing circuit measures the instantaneous path delay profile drift incurred with each frequency correction, and integrates the instantaneous drift measurements over time to yield a path delay profile drift. The drift (or its rate of change) is then used to adjust a frequency correction value so as to minimize the drift.

摘要： A user equipment (UE) in a mobile communications system is operated in a manner that alleviates or avoids an overload condition in the UE. This involves operating a receiver of the UE to receive one or more data blocks via a channel. In response to a user equipment overload condition being detected, a channel quality indicator (CQI) value is reported to a serving base station, wherein the reported CQI value represents a channel quality that is lower than an actual quality of the channel. The UE is then operated in a manner that is consistent with the reported CQI value. UE overload conditions include overheating, and an inability to process received data blocks at the rate at which they are being received.

摘要： A method for generating a power control command in a transceiver in a wireless communication system, where the method comprises the steps of calculating, at the beginning of a predefined time period, a quality measure reference value, generating, repeatedly during the predefined time period, an estimated quality measure value of a signal received at the transceiver; generating a power control command in dependence of the estimated quality measure value and the quality measure reference value; and generating, a number of times during the predefined time period, a modified quality measure reference value from the quality measure reference value. The step of generating the power control command comprises comparing the estimated quality measure value with the modified quality measure reference value. A power control unit, comprising a quality measure estimator, a calculator, a first controller, a second controller and an inner loop element, is configured to implement the method.
