Abstract: PURPOSE: A transmission method is provided to allocate a CP based on maximum distance between base stations in a single frequency network. CONSTITUTION: A BS(Base Station) calculates maximum distance between two base stations in an SFN(Single Frequency Network)(S410). The base station determines the calculated maximum distance as the length of CP(Cyclic Prefix)(S420). The base station transmits an OFDM(Orthogonal Frequency Division Multiplexing) symbol as the length of the CP which is set on SFN(S430).

Abstract translation: 目的：提供一种基于单个频率网络中基站之间的最大距离来分配CP的传输方法。 规定：BS（基站）计算SFN（单频网络）中的两个基站之间的最大距离（S410）。 基站将计算出的最大距离确定为CP的长度（循环前缀）（S420）。 基站发送OFDM（正交频分复用）符号作为在SFN上设置的CP的长度（S430）。

Abstract: PURPOSE: A transmission method for reducing packet transmission time is provided to prevent packet loss of an inter-SFN(Single Frequency Network) handover and to reduce packet transmission time. CONSTITUTION: A mobile broadcasting system uses the number of total packets of burst for the transmission of a broadcasting signal and the number of SFN(Single Frequency Network)s. The mobile broadcasting system determines a duplicate packet for the transmission of a broadcasting signal which is transmitted from single frequency network. The mobile broadcasting system transmits the burst of the broadcasting signal and the burst of single frequency network cell.
