System access method and apparatus of a narrowband terminal in a wireless communication system supporting wideband and narrowband terminals

摘要

A system access method of a narrowband terminal is provided for supporting both wideband and narrowband terminals in a cellular radio communication system. The method includes broadcasting a Shared CHannel (SCH) for a terminal to acquire system synchronization; transmitting a Low-end Master Information Block (L-MIB) including control information on an L-subframe configuration for supporting a second type terminal and a sub-band configuration of the L-subframe; transmitting a Low-end System Information Block (L-SIB) including information on downlink reception and uplink transmission of the second type terminal; and performing a random access procedure, when an attach request is received from one of the first type terminals and the second type terminals.

1. A signal transmission method of a base station in a wireless communication system supporting first type terminals operating on a first bandwidth and second type terminals operating on a second bandwidth, the signal transmission method comprising:
broadcasting a Synchronization CHannel (SCH) for a terminal to acquire system synchronization; transmitting a Low-end Master Information Block (L-MIB) including control information on an L-subframe configuration for supporting a second type terminal and a sub-band configuration of the L-subframe; transmitting a Low-end System Information Block (L-SIB) including information on downlink reception and uplink transmission of the second type terminal; and performing a random access procedure, when a Random Access Channel (RACH) preamble request is received from one of the first type terminals and the second type terminals.
