摘要： A method of operation of a mobile telecommunication system includes: measuring a received reference signal; removing a guard portion from the received reference signal; determining a noise variance estimate from both a noise region of the received reference signal and a noise sample in a signal region of the received reference signal, or calculating a dispersion power of a noise region of the received reference signal and determining the noise variance estimate based on at least a dispersion power; and calculating a signal to noise ratio from the noise variance estimate for adjusting a receiver device.

摘要： A method of operation of a mobile telecommunication system includes: measuring a measured target power and a measured server power; predicting a future target power and a future server power for a prediction tap number from when the measured target power and the measured server power are measured; computing an estimation error and a prediction error associated with the future target power and the future server power; determining a handoff hysteresis level based on the estimation error and the prediction error; and sending a handoff trigger for transferring a mobile station from a server station to a target station when the future target power minus both the future server power and the handoff hysteresis level is greater than zero.
