1. A method of controlling transmit power in a wireless device, wherein a desired transmit power is determined as a result of detection of a receive signal parameter, the method comprising:

  • detecting a desired maximum transmit power;

    generating a sequence of attenuation factors by monotonically increasing a variable at a controlled rate between a starting value and the maximum transmit power; and

    using each attenuation factor in turn to a) reduce the measured value of the received signal power; and

    b) reduce a determined desired value of the transmit power, whereby the transmit power is continually reduced as the variable is increased.
