The present invention provides a method for random access executed at user equipment (UE), comprising: receiving configuration information from a base station, the configuration information indicating an anchor carrier and/or one or a plurality of non-anchor carriers supporting a random access; selecting a carrier from the anchor carrier and/or the one or plurality of non-anchor carriers supporting a random access as a random access carrier according to the configuration information; and performing a random access by using the random access carrier. The present invention further provides a method for a random access executed at a base station, corresponding UE, and a corresponding base station.
