Abstract: A receiver 10 and method in the receiver for cell search to find an actual base station having a carrier frequency in a radio communications network 1. The receiver detects a first signal representative of a base station 12,14,16,18 by performing slot synchronisation, frame synchronization, cell identification, measurement of a signal quality of the first signal and comparison of the measured signal quality with a first threshold value. When a first signal having a signal quality that is greater than the first threshold value has been detected, the receiver searches for at least one second signal representative of a base station for at least one frequency offset comprised in a set of offsets S3. Further, when one or more second signals are detected, the receiver selects the signal with the highest signal quality, and detects a broadcast radio channel representative of a base station for the selected signal.
