Patent ID: 8594647

Claim:
A method for self-adaptive adjustment of pilot power of Femto Cell, comprising: initializing pilot power of a Femto Cell, and determining, by the Femto Cell, an adjustment value of the pilot power according to a signal-to-noise ratio reported by a Home User Equipment (HUE) in real time, wherein initializing the pilot power of the Femto Cell comprises: obtaining a Received Signal Coding Power (RSCP) threshold of edge pilot power of the Femto Cell through link budget; setting a pilot power threshold of the Femto Cell based on a maximum downlink transmission power of the Femto Cell; and setting an initial value of the pilot power of the Femto Cell as a smaller one from the RSCP threshold of the edge pilot power of the Femto Cell or the pilot power threshold, wherein obtaining the RSCP threshold of edge pilot power of the Femto Cell through link budget comprises: introducing a radius of the Femto Cell and a number of indoor walls into a link budget reference formula PL=37+20 log d+qW to calculate link loss, where PL is the link loss or path attenuation, and its unit is dB; d is the radius of Femto Cell, and its unit is meter; q is the number of indoor walls and varies depending on d; adding an effective demodulation threshold of the HUE to the link loss to obtain the RSCP threshold of the pilot.
