Narrowband terminal system system access device and apparatus in wireless communication system supporting broadband and narrowband terminals

摘要

A signal transmission procedure performed by a base station in a wireless communication system that supports first type terminals operating in a first bandwidth and second type terminals operating in a second bandwidth, the transmission method comprising Signal: broadcast a shared channel, SCH, for a second type terminal to obtain system synchronization; transmitting a lower end master information block, L-MIB, which includes control information about a subframe configuration L to support the second type terminal and a subband configuration of subframe L; transmitting a lower end system information block, L-SIB, which includes information on downlink reception and uplink transmission of the second type terminal; and perform a random access procedure, when a random access channel preamble, RACH, is received from one of the first type terminals and the second type terminals.
