Reduced capability/complexity NR bandwidth part configuration
A configuration to allow a UE to receive a BWP configuration that supports RC NR. The UE sends information to a network indicating a UE capability of the UE. The UE receives, based on the UE capability, information indicating a BWP associated with a first BWP, the second BWP having a frequency range equal to or less than the first BWP. The UE receives at least one of control information or data based on the indicated first BWP and the second BWP.
