APPARATUS AND METHOD FOR USING GUARD BAND AS DATA SUBCHANNEL IN COMMUNICATION SYSTEM BASED FREQUENCY OVERLAY

摘要

A method and an apparatus for using protection band as data subcarrier for transmitting the signal in a communication system are provided to increase frequency efficiency by utilizing protection band as data subcarrier. A frequency synchronization is obtained through preamble about a first FA(300). The information about a first addition radio resource is received(302). By using the whole radio resource including the first addition radio resource, the first network entry procedure is performed(304). Among the first network entry process execution, the frequency overlay decided operation is negotiated(306). The information about the second addition radio resource is received(308). By using the whole radio resource including the second addition radio resource, the secondary network entry procedure is performed(310).
