Patent ID: 8520721

Claim:
A method of controlling power in a communication system, the method comprising: correlating a received signal, received at a receiver, with a known sequence to determine a correlation metric over a correlating period of time; measuring a plurality of sampled power levels from the received signal at a frequency whose period is less than the correlating period of time, wherein the received signal comprises a pulsed noise signal, and wherein the pulsed noise signal interferes with the received signal for a portion of the period of time; determining a high-energy metric based upon an average of the plurality of sampled power levels; determining a signal power using the correlation metric and the high-energy metric, wherein at least a portion of the pulsed noise signal power is excluded from the signal power based upon at least 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 determined signal power, wherein the uplink signal is transmitted at a first time based on a slot start time and a first random timing offset, wherein the uplink signal is transmitted while at least a portion of a second signal is transmitted from a second node such that both the uplink signal and the second signal are received, and wherein the second signal is transmitted at a second time based on the slot start time and a second random timing offset.
