Abstract
A cellular communication system is disclosed in which user equipment (UE) initiates a random access channel (RACH) procedure by sending one or more messages, comprising a random access preamble, to a 5G base station, using one or more uplink carriers of a plurality of such carriers available for use by the UE. The base station selects an uplink carrier for initial access by the UE and informs the UE, as part of the RACH procedure, of the UL carrier selected by the base station.
