Abstract:
A method of wireless communication includes a random access channel configuration for narrow bandwidth operations within a wider LTE system bandwidth. A first random access channel (RACH) configuration is broadcast for a regular device. A second RACH configuration is broadcast for a narrow bandwidth device. The narrow bandwidth device operates in a narrower bandwidth than the regular device.
