1. A method for wireless communications by a base station (BS), comprising:
generating a primary synchronization signal (PSS) utilizing a first code sequence and a cover code applied to the first code sequence over a first number of symbols within one or more subframes, wherein the cover code comprises a binary sequence; and
transmitting the PSS to a first type of a user equipment (UE) that communicates on one or more narrowband carrier regions, wherein the one or more narrowband carrier regions is within a guard-band of a wider carrier bandwidth.
