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： 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.

For example, in one embodiment the Rake receiver circuit comprises one or more processing circuits that are configured to generate Rake combining weights in a first mode of operation as first combining weights calculated from channel estimates corresponding to a set of Rake signal fingers.

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： A method of detecting a desired signal within a composite signal provides for suppression of interfering signal(s). The method, implemented in a wireless communication apparatus, for example, includes receiving the composite signal and obtaining sample values therefrom. At least some of the sample values include desired and interfering signal components. The method further includes generating an interfering signal channel estimate by: forming sample pairs for some or all of the sample values; identifying sample pairs of interest as those sample pairs in which the interfering signal component is the same; and calculating the interfering signal channel estimate as an average value determined from one or more of the sample pairs of interest. The method further includes detecting desired signal symbols from the composite signal in a joint detection process that functionally depends on the interfering signal channel estimate.
