Abstract
The invention relates to a method for estimating the C/I density and interference probability in the uplink. According to the invention, two or more base stations synchronously measure signal strength and signal identity in the uplink in their own and each other's channels. By measuring over a sufficiently long time, a statistical basis for how the signal strengths from mobiles connected to a respective base station are distributed is obtained. From the basis, density functions for the signal strength from traffic to its own and, respectively, another station can be formed. Due to the synchronous measuring method, the functions can be normalized and a C/I or C/I+N density function can be formed, from which the interference probability can be calculated (FIG. 1).
