Abstract

Method and apparatus for controlling transmission power in a closed loop power control system, wherein power control commands are based on the energy of the previous power control commands. In one embodiment, the method compares changes in the received energy of received power control commands against expected changes in those commands based on previously transmitted power control commands, and identifies suspicious responses to said previously transmitted power control commands. Hypothesis testing of the received power control commands is performed accordance any identified suspicious responses.
