1. A user equipment (UE), comprising:
a transceiver; and
a processor operably coupled to the transceiver and configured to:
identify a plurality of groups of physical random access channel (PRACH) resources, wherein each of the plurality of groups is associated with a set of features for the UE,
determine a target group of PRACH resources from the plurality of groups, and
perform a random access procedure based on the determined target group of PRACH resources,
wherein the plurality of groups includes a first group of PRACH resources associated with a first set of features for the UE and a second group of PRACH resources associated with a second set of features for the UE, and
wherein the transceiver is further configured to:
receive information on a first uplink (UL) bandwidth part (BWP) associated with the first group of PRACH resources, and
receive information on a second UL BWP associated with the second group of PRACH resources.
