1. A method for network access carried out in a user equipment (UE), the method comprising:
acquiring at least one of a plurality of synchronization signals transmitted from a base station, each synchronization signal identifying a synchronization resource usable for identifying an associated access channel resource of a sequence of access channel resources;
synchronizing to the base station based on the at least one synchronization signal;
obtaining, from the base station, information identifying a first access channel resource and a second access channel resource;
transmitting an access preamble in the first access channel resource, and
transmitting, based on meeting a repetition criteria, said access preamble in the second access channel resource for enhanced coverage operation.
