FIELD: physics.
SUBSTANCE: invention relates to execution of random access on user equipment (UE). Method comprises: obtaining configuration information from a base station, wherein configuration information indicates anchor carrier and/or one or more non-empirical carriers supporting random access; selection of carrier from anchor carrier and/or one or multiple non-empirical carriers supporting random access, as a random access carrier in accordance with configuration information; and performing random access using a random access carrier. Present invention further discloses a random access method performed at a base station corresponding to a UE and a corresponding base station.
EFFECT: technical result is providing random access for non-core carriers.
