METHOD OF CLOSED LOOP POWER CONTROL ADJUSTED BY SELF-INTERFERENCE
First Claim
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 delay spread of the received signal from the mobile device; and
modifying power control command generation based on said delay spread so as to limit increases in the mobile device transmit power as the delay spread increases.

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. The amount of self-interference is determined based on the delay spread of the channel.
