Abstract: A wireless communication unit comprises a transmitter comprising a power amplifier, an inner feedback power control loop having a power control logic module comprising loop priming logic module operably coupled to the power amplifier, and a switchable outer digital loop comprising switchable logic module. The loop priming logic module is arranged to set a power reference value for controlling the power amplifier prior to a ramping operation of the power amplifier and the switchable logic module switching the switchable outer digital loop on or off, thereby restricting adverse transient behavior of the power amplifier.

Abstract: A wireless subscriber communication unit comprises a transmitter having a power amplifier and a feedback power control loop having a power control function arranged to set an output power level of the power amplifier. The power control function is arranged to perform a back-off of the output power prior to completion of a transmission burst.

Abstract: Methods and device for transmitting a sequence of transmission bursts in a wireless device. The method includes transmitting a sequence of transmission bursts according to a transmission schedule. The method is characterized by: receiving, at a radio frequency integrated circuit, prior to a transmission of at least one transmission burst of the sequence, information representative of the timing of the transmission of the at least one transmission burst; and generating timing signals, by the radio frequency integrated circuit that implement the transmission schedule. A wireless device includes a base band integrated circuit adapted to determine a transmission schedule of a sequence of transmission bursts. The wireless device is characterized by including a radio frequency integrated circuit that is adapted receive information representative of the timing schedule and to autonomously control a transmission of the sequence of transmission bursts.

Abstract: A control loop has a control slope associated therewith. The control loop is provided to control a unit under control. A method of regulating the control slope comprises the step of measuring the control slope of the control loop and modifying a parameter associated with the unit under control in order to maintain the control slope within a desired range. Lock of the control loop is therefore maintained.
