摘要： Efficient carrier aggregation is enabled in a receiver employing a single frequency source, and dividing the frequency source by different frequency dividing factors to generate two or more RF LO frequencies. Received signals are down-converted to intermediate frequencies by mixing with the respective RF LO frequencies. By utilizing only a single high frequency source, embodiments of the present invention avoid spurious and injection locking issues that arise when integrating two or more frequency sources, and additionally reduce power consumption as compared to a multiple frequency source solution.

摘要： A conversion circuit (20) for converting a complex analog input signal having an in-phase, I, component and a quadrature-phase, Q, component resulting from frequency down conversion of a radio-frequency, RF, signal (XRF) to a frequency band covering 0 Hz into a digital representation is disclosed. It comprises a channel-selection filter unit (40) arranged to filter the complex analog input signal, thereby generating a channel-filtered I and Q components, and one or more processing units (53, 53a-b). Each processing unit comprises four mixers (60-75) for generating a first and a second frequency-translated I component and a first and a second channel-filtered Q component based on two LO signals with equal LO frequency and a 90° mutual phase shift. Furthermore, each processing unit comprises a combiner unit (85, 120) for generating a first, a second, a third, and a fourth combined signal proportional to sums and differences between said frequency translated I and Q components. The first and the fourth combined signals form a first complex signal, and the second and the third combined signals form a second complex signal. Each processing unit further comprises four ADCs (110a-d, 115a-d) for providing digital representations of the first complex signal and the second complex signal for forming said digital representation of the analog complex input signal. A related radio receiver circuit and a related electronic apparatus are also disclosed.

摘要： Teachings herein schedule a data transmission in a variable bandwidth wireless communication system based on the power efficiency of a mobile node. One or more processing circuits, of the mobile node or a network node, determine the value of a control setting that defines a power efficiency configuration of the mobile node. In one embodiment, for example, the power efficiency configuration indicates the mobile node is configured to operate at the maximum power efficiency attainable without the data rate of the data transmission falling below a minimum data rate required by a quality of service. Regardless, the one or more processing circuits select from different possible bandwidths of the data transmission a bandwidth that supports a given data rate and that, according to a power efficiency model that models power efficiency of the mobile node for the different possible bandwidths, yields a power efficiency comporting with the power efficiency configuration.

摘要： A method of scheduling wireless data transmissions between a mobile terminal and a base station using multiple system carrier signals is disclosed. The method comprises the steps of receiving (101) the mobile terminal information from the base station indicating available system carriers; detecting (102) at least one dynamic parameter indicative of the mobile terminal's current capability to handle non-contiguous system carriers; determining (103) from the dynamic parameter whether a situation has occurred where the mobile terminal's capability to handle non-contiguous system carriers has been reduced; modifying (104), in such case, feedback information to be transmitted to the base station; and transmitting (105) the modified feedback information to the base station. By modifying the feedback information in this way the mobile terminal reduces the likelihood that the base station allocates non-contiguous system carriers to the mobile terminal in situations where it has a reduced capability of handling such system carriers.

摘要： A method of scheduling wireless data transmissions between a mobile terminal (701) and a base station using multiple component carrier signals is disclosed. The method comprises the steps of: receiving in the mobile terminal information from the base station indicating available component carriers; detecting in the mobile terminal at least one dynamic parameter indicative of the mobile terminal's current ability to handle component carriers having non-contiguous bandwidths; determining in the mobile terminal in dependence of the at least one dynamic parameter which of the available component carriers to utilize; and transmitting from the mobile terminal to the base station information indicating the component carriers determined to utilize. By doing this the mobile terminal may choose to limit the number of component carriers used in situations where it is disadvantageous, such as situations where the power consumption of supporting multiple component carriers is high or situations where complex hardware is needed.

摘要： The invention relates to a complex intermediate frequency (CIF) mixer stage, methods of operation thereof, and methods of calibration thereof. The CIF mixer stage comprises numerous individual mixers driven by IF clock signals to down-convert received IF signals into a set of signals at baseband frequency which are further combined to form a lower side band signal and an upper side band signal. The IF clock signals used have a predefined phase relationship among them, which involves tuneable phase skews. By calibration of the conversion gains and the phases of the IF clock signals the gain and phase imbalance introduced in a preceding radio frequency mixer stage and/or the CIF mixer stage can be cancelled. Further, in-channel IQ leakage control can be applied to the lower side band signal and/or the upper side band signal. The CIF mixer stage can thus effectively suppress image interference and IQ leakage.

摘要： A user equipment (UE) in a communication system can keep track of the cell/frequency deployment of a network operator preferred by the user, and based on the tracked information, the UE can build up its own user-specific Neighbor Cell List. When the UE is roaming, the UE does received-signal measurements according to cells and carrier frequencies identified in the broadcast Neighbor Cell Lists of the roamed-into network, but the UE also does received-signal measurements (with higher priority) according to the user-specific Neighbor Cell List that it has built up. Accordingly, a UE implementing a user-specific Neighbor Cell List analyzes its radio environment based on received signals and stores information about that environment, including user-preference information that prioritizes cells in the radio environment. The UE can then carry out cell search based on the stored environment and user-preference information.
