Abstract

A User Equipment, UE, supporting communication in a multicarrier radio communication system and a method therein for receiving information from a Radio Base Station, RBS, are provided. The method comprises determining 310 a bandwidth by which the UE will receive information, the bandwidth comprising a plurality of subcarriers. The method also comprises adjusting 320 a bandwidth of the UE to correspond to the determined bandwidth by which the UE will receive information; and fine tuning 330 a local oscillator of the UE such that a centre frequency of a local oscillator does not coincide with a predetermined subcarrier transmitted from the RBS.
