Abstract  Abstract

A user equipment (UE) comprises a processor configured to execute executable instructions to receive configuration information associated with at least two uplink carriers from a base station, the at least two uplink carriers including a supplementary uplink carrier and a normal uplink carrier, select one of the at least two uplink carriers of the base station if a power of a first downlink reference signal from the base station and measured by the UE is below a first threshold value, select a contention-free random access (CFRA) resource associated with a second downlink reference signal on the selected uplink carrier of the base station if a power of the second downlink reference signal from the base station and measured by the UE is above a second threshold value, and perform a random access procedure with the base station by using the selected CFRA resource over the selected uplink carrier.
