Patent ID: 7769350

Claim:
A method for adapting at least one system parameter, the method comprising: defining a connection between a transmitter unit and a receiver unit in a radio based communications system, wherein an adaptation frequency at which the system parameter is adapted is dependent on at least one derivative of order n, n=0; 1, of a distance between the transmitter unit and the receiver unit with respect to time, and dynamically determining the at least one derivative during system operation, wherein the adaptation frequency is dynamically determined as v=min{v min +K·(|Δf|)/(f 0 ·T), v max }, wherein v min is a minimum adaptation frequency, v max is a maximum adaptation frequency, Δf is a frequency shift of a radio frequency signal transmitted between the transmitter unit and the receiver unit, f 0 is a nominal radio frequency of the radio frequency signal, T is a signal propagation time of the radio frequency signal, and K is a system constant.
