1. A method of controlling power in a communication system, the method comprising:
- measuring a plurality of sampled power levels from a received signal at a receiver, wherein the received signal comprises a pulsed noise signal;
correlating the received signal with a known sequence to determine a correlation metric;
determining a signal power excluding power of the pulsed noise signal, wherein the signal power is determined using the correlation metric and the plurality of sampled power levels; and
transmitting an uplink signal at a transmit power at a transmitter wherein the transmit power is based in part on the signal power excluding power of the pulsed noise signal.

Abstract
This disclosure relates to method, device and system for controlling power in a communication system. A plurality of power levels is measured from a received signal that includes a pulsed noise source. The received signal is correlated with a known sequence creating a correlation metric. A signal power is determined based on the correlation metric and the plurality of power levels. An uplink signal is transmitted at a transmit power that is based on the signal power.
