The femto base station generates a sequence of a preamble including information about a frequency band on which the femto base station operates, maps the IWS including the sequence of the preamble to a plurality of subcarriers on a frequency domain, and transmits the IWS to a terminal through the subcarriers. The IWS can be mapped to the plurality of subcarriers positioned on one equal OFDM (Orthogonal Frequency Division Multiplexing) symbol on a time domain or a plurality of preset RUs (Resource Unit).

    摘要: A method for acquiring a multi-cell specific message in a wireless communication system includes receiving a downlink preamble, receiving the multi-cell specific message weighted with the downlink preamble, and decoding the weighted multi-cell specific message by using the received downlink preamble. Accordingly, since a preamble is used to transmit a multi-cell specific message, there is no need to transmit an additional signal in order to estimate a channel of the multi-cell specific message. In addition, a user equipment can acquire the multi-cell specific message by simply performing decoding.

    摘要: A method of transmitting data in a wireless communication system is provided. The method includes generating duplicate data by using repetition coding, the duplicate data being the same as original data, shifting the phase of the duplicate data, and transmitting the original data and the phase-shifted duplicate data. The duplicate data is mapped to a modulation symbol having a different size or phase as that of the original data, thus to reduce the PAPR unlike the general repetition coding.
