A method for controlling a bandwidth used for processing a baseband transmit signal by a transmit path of a transmitter is provided. The method includes generating a first comparison result by comparing, to a threshold value, a first number of physical resource blocks allocated to the transmitter for a first transmission time interval. Further, the method includes generating a second comparison result by comparing, to the threshold value, a second number of physical resource blocks allocated to the transmitter for a subsequent second transmission time interval. The method additionally includes adjusting the bandwidth based on the first and the second comparison results.

A communication device is described comprising a transmitter configured to transmit data according to a retransmission protocol, a determiner configured to determine whether, for a transmission time scheduled according to the retransmission protocol, there was a transmission gap within a predetermined time interval before the transmission time or to determine whether there will be a transmission gap within a predetermined time interval after the transmission time and a controller configured to control the transmitter to perform an initial transmission of data or a retransmission of data according to the retransmission protocol at the transmission time based on the result of the determination.

A radio receiver includes an in-phase channel and a quadrature channel, the channels being provided in parallel at a respective input with quadrature modulated radio frequency signals; and an error correction loop for detecting and correcting an imbalance in gain between at least part of the in-phase channel and a corresponding part of the quadrature channel, wherein the error correction loop comprises: a detector adapted to calculate Error_det=|I'|&#x2212;|Q&#x2032;|, where I&#x2032; and Q&#x2032; are the in-phase and quadrature channels respectively; a loop filter arranged to receive Error_detfrom the detector and calculate loop_filter_out+=K* Error_det, where Kis the loop filter constant and loop_filter_outhas an initial value of 1; and a multiplier arranged to receive loop_filter_outfrom the loop filter and adjust the signal of the quadrature channel by multiplying the signal by loop_filter_out.
