METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA IN AN ORTHOGONAL FREQUENCY MULTIPLEXING SYSTEM

摘要

A method and apparatus for transmitting and receiving data in an Orthogonal Frequency Division Multiplexing (OFDM) system are provided, in which a Base Station (BS) generates a signal of a broadcast channel, determines whether the broadcast channel signal includes Reference Symbols (RSs) used for channel estimation, determines to apply a maximal puncturing pattern to a Resource Block that defines the broadcast channel, if the broadcast channel signal includes Rs, includes puncturing information about a downlink signal in the broadcast channel signal, maps the broadcast channel signal including the puncturing information to Resource Elements according to the maximal puncturing pattern, and transmits the mapped broadcast channel signal.
