Abstract:
A method, performed by a wireless device (130), for handling access to a cell (120). The wireless device (130) operates in a wireless communications network (100). The wireless device (130) determines (302), given a first uplink carrier (141) in use during a random access procedure to the cell (120), whether or not a second uplink carrier (142) is to be used during the random access procedure to the cell (120), instead of the first uplink carrier (141). The cell (120) is served by a network node (110) operating in the wireless communications network (100). The wireless device (130) then uses (305), based on a result of the determination, one of the first uplink carrier (141) and the second uplink carrier (142), to continue the random access procedure to the cell (120).
