    摘要： A technique for calibrating a receiver apparatus comprising at least one analog signal processing component and an intermediate frequency, or IF, mixer for converting IF signals comprising an in-phase, or I, signal and a quadrature-phase, or Q, signal to baseband frequency signals is provided. The IF mixer is arranged downstream of the at least one analog signal processing component. A method implementation of the technique comprises the steps of determining, in a digital processing domain downstream of the IF mixer, a metric which is affected by a frequency dependency of an imbalance between I and the Q signal, or IQ-imbalance, over a signal bandwidth, generating, based on the metric thus determined, a calibration signal configured to at least partially compensate a frequency-dependency of the IQ imbalance, and feeding the calibration signal to the at least one analog signal processing component so as to calibrate the at least one analog signal processing component.

    摘要： This disclosure provides a microwave radio transmitter apparatus comprising an antenna arrangement and a precoder module connected to the antenna arrangement. The precoder module comprises an estimation module. The precoder module is configured to receive a number N of signals s1, . . . , sN and to generate N phase-adjusted transmit signals TX1, . . . , TXN. The antenna arrangement comprises N antenna elements ai, i=1, 2, . . . , N. Each antenna element ai is configured to obtain a respective phase-adjusted transmit signal TXi from the pre-coder and to transmit the respective phase-adjusted transmit signal TXi. The precoder module is configured to obtain an observation receive signal RX, the observation receive signal comprising signals transmitted from the N antenna elements. The estimation module is configured to estimate for each antenna element ai a phase difference between the corresponding transmit signal TXi and the observation receive signal RX. The precoder module is configured to adjust each transmit signal based on the estimated phase difference.

    摘要： Aspects of the present disclosure provide an apparatus and method of utilizing a filtered transmit power margin calculation, rather than an instantaneous Tx power, to determine whether or not to trigger an Event 6D report. The filtered transmit power margin may take into account not only the user equipment's transmit power and the maximum transmit power level, but in addition, a received maximum power reduction value.
