Abstract
Embodiments herein relate to a method in a user equipment (10) for acquiring system information relating to a cell (11,14) in a radio communications network. The cell (11,14) is served by a network node (12,12′,15) and the user equipment (10) is capable of receiving signals on more than one downlink carrier simultaneously. The user equipment (10) creates autonomous gaps on a downlink carrier, which downlink carrier to use for creating autonomous gaps on is based on a received indication from the network node (12,12′,15) and/or a pre-determined rule. The indication or pre-determined rule specifies the downlink carrier. The user equipment (10) then acquires the system information of the cell (11,14) on the downlink carrier using the created autonomous gaps.
