Abstract: Apparatuses (including base stations and terminals), systems, and methods for supporting both wideband and narrowband communications are described. In one aspect, a base station supporting first type terminals operating on a first bandwidth and second type terminals operating on a second bandwidth is described, having an information formatter, a transceiver, and a controller. The information formatter generates a Low-end Master Information Block (L-MIB) and a Low-end System Information Block (L-SIB), which are transmitted by the transceiver to first type and second type terminals. The L-MIB includes control information on an L-subframe configuration for supporting a second type terminal and a sub-band configuration of the L-subframe, while the L-SIB includes information on downlink reception and uplink transmission of the second type terminal. When the base station receives a Random Access Channel (RACH) preamble request from one of the terminals, the base station performs the random access procedure.

Abstract: Methods and apparatus are provided for transmitting and receiving a control signal. Indices of Resource Block (RB) sets are transmitted through higher layer signaling. Downlink Control Information (DCI) generated in a short DCI format is transmitted from a Base Station (BS) to a terminal. The DCI includes a first index indicating an RB set having at least one allocated RB and a second index indicating the at least one allocated RB. The terminal determines whether short DCI format is configured to be used. When the short DCI format is configured to be used, the first index and second index are received. The terminal communicates through the at least one allocated RB identified by the first and second indices.
