Patent ID: 7657275

Claim:
A method of controlling transmit power for a data transmission in a wireless communication system, comprising: detecting for a transmit power spike based on a first set of at least one criterion, the transmit power spike being a sudden change in the transmit power and used to determine whether to adjust the transmit power in accordance with a first state or a second state; if a transmit power spike is not detected, adjusting the transmit power based on transmit power control (TPC) decisions in accordance with the first state, wherein the transmit power is increased by a first amount for each TPC decision indicating an increase in transmit power and decreased by a second amount for each TPC decision indicating a decrease in transmit power; and if a transmit power spike is detected, adjusting the transmit power based on TPC decisions in accordance with the second state and further to reduce change in the transmit power and reduce adverse effect of the transmit power spike, the reduced change in the transmit power resulting in greater errors in the transmit power versus directly applying the TPC decisions in accordance with the first state.
