Abstract
Embodiments herein relate for example to a method performed by a wireless device in a first wireless communication system that is deployed on a frequency resource. The wireless device receives information indicating a PRB offset and a corresponding channel raster offset. The channel raster offset is an offset in frequency between a channel raster, used by the wireless device (105) in a cell search process, and the frequency resource. The PRB offset indicates an offset between the frequency resource and an inner frequency resource on which a second wireless communication system is deployed. In the frequency domain, the second wireless communication system is deployed on at least one higher frequency resource above the inner frequency resource and at least one lower frequency resource below the inner frequency resource. The wireless device determines, based on the received information, an adjustment in frequency applicable for the frequency resource on which the first wireless communication system is deployed.
