1. A method, comprising:
acquiring, by a bandwidth-limited user equipment (UE) having a bandwidth capability, a signal from a network, the signal comprising:
a System Information Block #1 (SIB1) defining a legacy initial bandwidth part (BWP); and
a bandwidth-limited Secondary Synchronization Signal (BL-SSS) indicating support, by the network, for the bandwidth-limited UE;
sending, by the bandwidth-limited UE, a first message to the network indicating the bandwidth-limited UE's choice of an initial BWP;
receiving, by the bandwidth-limited UE, a second message from the network indicating an initial BWP switch;
in response to the initial BWP switching indicated in the second message, sending, by the bandwidth-limited UE, a third message to the network in a first initial BWP that is different from the legacy initial BWP; and
receiving, by the bandwidth-limited UE, a fourth message from the network in a second initial BWP that is different from the legacy initial BWP.
