1. A method for wireless communication in a system that supports operation in a narrowband region of a system bandwidth, comprising:
identifying a location of the narrowband region of the system bandwidth as a single resource block within a wideband region of the system bandwidth; and
transmitting an indication of the location of the single resource block within the wideband region of the system bandwidth, wherein the indication comprises a total wideband bandwidth of the system bandwidth and one or more common reference signal (CRS) resource elements (REs) included in the single resource block and is based at least in part on an offset with respect to a center of the wideband region.
