1. A method of controlling the transmit power of a mobile device in a mobile communication network, said method comprising:
- generating power control commands for controlling a transmit power of a mobile device by comparing a received signal quality of a received signal from the mobile device to a signal quality target;
determining a level of self-interference in the received signal from the mobile device; and
modifying power control command generation when the level of self-interference is the dominant impairment in the received signal to constrain increases in the mobile device transmit power.

Abstract
A method and apparatus for controlling the transmit power of a mobile device in a mobile communication network takes the level of self-interference into account to perform inner-loop power control. For normal inner-loop power control, a signal quality estimate is compared to a signal quality target and power control commands are generated based on the comparison. When self-interference is the dominant impairment in the received signal, a “fast break” is introduced to change inner-loop power control command generation.
