摘要： A network unit of an own cell is operated in a radio communication system utilizing a radio interface that includes a radio frame made up of a number of sub-frames. The own cell serves one or more user equipments. Operation includes obtaining information about a scheduling of MBSFN data transmissions in one or more neighboring cells. The information thereby obtained is used to generate an information signal that, for a given sub-frame, enables the one or more user equipments to determine whether neighboring cell measurements can be performed using a unicast group of Orthogonal Frequency Division Multiple access (OFDM) symbols. The information signal is transmitted to the one or more user equipments, which can then use the information to determine how to locate cell-specific reference symbols when doing measurements of neighboring cells.

摘要： Techniques are disclosed for determining which channelization codes are used for an interfering HS-PDSCH transmission without knowing whether a neighboring UE targeted by that transmission has had its 64QAM capability activated by higher layer signaling. The average amplitude is measured for each of several possible groups of channelization codes for each of one or more nearby UEs that might be the targets of interfering HS-PDSCH messages. Testing whether the amplitude is approximately the same across the codes in a possible combination of channelization codes yields a metric value that indicates whether that particular combination of codes is likely to be transmitted to a given UE. A second metric that detects the most likely modulation for possible groups of channelization codes is also calculated. The metrics are combined to determine which combination of channelization codes and modulation scheme is most likely being used for addressing the neighboring UE.

摘要： Methods and apparatus for providing automatic gain control (AGC) for received multi-carrier signals are disclosed. A receiver circuit comprises a common analog signal path, which includes an analog variable-gain circuit and an analog-to-digital converter, and further comprises first and second carrier-specific, digital variable-gain circuits corresponding to first and second carriers of the received multi-carrier signal, respectively. The receiver circuit further includes a gain control circuit configured to control the analog and digital variable-gain circuits and to allot gain adjustments to the analog variable-gain circuit based on a difference between carrier signal levels for the first and second carriers. In some embodiments, the gain control circuit selectively operates in an all-carrier mode, in which analog gain adjustments are calculated from both of the carrier signal levels, or in an unequal-priority mode, in which analog gain adjustments are calculated from only one of the first and second carrier signal levels.

摘要： Methods and apparatus for processing a received multi-stream (MIMO) signal, and in particular for estimating a per-code traffic-channel-to-pilot power ratio for the MIMO signal are disclosed. An exemplary method includes the calculation of an average symbol amplitude or average symbol power level from a plurality of de-spread traffic channel symbols received in a first transmission slot and the estimation of a corresponding pilot symbol amplitude or pilot symbol power level, based on an estimated propagation channel response and at least one of a plurality of precoding vectors used to generate the MIMO signal. A per-code traffic-channel-to-pilot power ratio for the first transmission slot is computed by dividing the average symbol amplitude or average symbol power level by the corresponding pilot symbol amplitude or pilot symbol power level.

摘要： A method and apparatus provide for setting processing delay assignments in a CDMA receiver using a flat-channel placement or using a dispersive channel placement, in dependence on characterizing the channel as flat or dispersive. For example, a receiver maintains a logical flag reliably indicating the current channel state as flat or dispersive, and assigns or otherwise sets processing delays—e.g., for received signal demodulation—using a flat-channel placement algorithm or a dispersive-channel placement algorithm. The flat-channel placement algorithm generally provides better performance in flat-channel environments, and the dispersive-channel placement algorithm generally provides better performance in dispersive channel environments. Such processing may be regarded as activating a simplified processing delay placement grid that offers better performance if the channel truly is flat, with the underlying advantage of providing a reliable mechanism for detecting flat channel conditions.

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： A processing circuit and method generate signal quality estimates based on scaling measured inter-symbol interference (ISI) in a received signal according to a cancellation metric corresponding to ISI cancellation performance of the receiver. By accounting for ISI cancellation performance of the receiver based on a simple scaling metric, accurate received signal quality measurements are obtained in a manner that accounts for un-cancelled ISI in the received signal without requiring use of potentially complex multipath combining weight calculations in the signal quality calculation. Signal quality estimation results may be used for sending corresponding Channel Quality Indicators, communication link transmit power control commands, etc. In some embodiments, the cancellation metric is maintained as a dynamic value based on measured ISI cancellation performance, while in other embodiments the cancellation metric comprises a pre-configured value stored in memory, for example.
