Patent ID: 7317751

Claim:
A method comprising: in particular in a base station of a WCDMA system, providing at least a first estimating process and a second estimating process, the method being used for estimating a signal to interference ratio of a signal, wherein for current use with the signal a selection among said estimating processes is made in accordance with a current characteristic or current characteristics of said signal so that an estimating process is selected which is adapted to the current characteristic(s) of said signal, wherein said first estimating process comprises a wideband interference estimation calculated from the wideband signal, that is the signal before despreading, and said second estimating process comprises a narrowband interference estimation calculated from the narrowband signal, that is the signal after despreading, wherein said first estimating process is used when said signal has a lower bit rate than signal used for second estimating process, and said second estimating process is used when said signal has a higher bit rate than signal used for first estimating process.
