1. A method comprising:
configuring a user equipment (UE) with a list of resources;
receiving, by the UE, an indication from a base station in a wireless communication network, wherein the indication allows the UE to select one or more resources from the list of resources to carry out an initial transmission of a contention resolution message and a re-transmission containing a non-zero repetition of the contention resolution message for a random access procedure in the wireless communication network;
