1. One or more baseband processors associated with a user equipment (UE) with reduced bandwidth (BW) support at both Radio Frequency (RF) and baseband, the baseband processor configured to perform operations comprising:
decoding configuration information, received from a base station, of one or more Common Search Spaces (CSSs) for M-PDCCH (Physical Downlink Control CHannel for MTC), the configuration information specifying a physical resource block (PRB) set for MDPCCH and a starting subframe of the M-PDCCH, the starting subframe being a function of a system frame number (SFN) or a function of an extended SFN, wherein the PRB set specifies a number of PRB pairs in the PRB set, and wherein a type of a scrambling of the configuration information is based on a type of a CSS of the one or more CSSs of the configuration information;
wherein the one or more CSSs are differentiated based on one or more enhanced coverage (EC) levels that are available to the one or more baseband processors, each CSS of the one or more CSSs configured for paging to a particular EC level of the one or more EC levels, the CSS defining, for the particular EC level, for one or more repetition levels;
determining an EC level; and
based on the EC level, monitoring for M-PDCCH transmissions according to the CSS associated with the determined EC level.
