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.

Abstract: An arrangement (400) for a user equipment, UE, is disclosed. The arrangement (400) comprises an acquiring unit (401) configured to acquire neighboring cell information relating to a plurality of neighboring cells. An assignment unit (403) is provided to assign a priority indicator to each neighboring cell based on the neighboring cell information. Also, a measurement unit (404) is provided to perform measurements on the basis of the assigned priority indicators. The arrangement (400) is arranged such that measurements can be performed more frequently for a neighboring cell having a first priority indicator compared with another neighboring cell having a second priority indicator, which second priority indicator is comparatively lower than the first priority indicator. The disclosure also presents corresponding methods, computer program products and devices.
