ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYMBOL DISTRIBUTING METHOD AND SYSTEM FOR MULTIMEDIA BROADCAST MULTICAST SERVICE SINGLE FREQUENCY NETWORK SUB-FRAME
摘要：
The present invention provides an Orthogonal Frequency Division Multiplexing (OFDM) symbol distributing method for Multimedia Broadcast multicast service Single Frequency Network (MBSFN) sub-frame. According to the uniform configuration rules, an OFDM symbol distributing system distributes the OFDM symbols in all MBSFN sub-frames bearing the transmission of the Multi-cell transmission Multimedia Broadcast Multicast Service (MBMS) in the MBMSFN domain. The present invention also correspondingly provides an OFDM symbol distributing system for MBSFN sub-frame. By configuring the OFDM symbols occupied by the PDCCH in the MBSFN sub-frame bearing the Multi-cell transmission MBMS, the present invention increases the frequency of the OFDM symbol that is occupied by the PDCCH bearing the MBMS in the MBSFN sub-frame, so as to effectively use the resource and avoid the interference to the PDCCH due to the MBMS data transmission to a certain extent.
摘要（中）：

本发明提供了一种用于多媒体广播多播服务单频网（MBSFN）子帧的正交频分复用（OFDM）符号分配方法。 根据统一配置规则，OFDM符号分配系统在MBMSFN域中携带多小区传输多媒体广播多播服务（MBMS）的传输的所有MBSFN子帧中分配OFDM符号。 本发明还相应地提供了一种用于MBSFN子帧的OFDM符号分配系统。 通过配置携带多小区传输MBMS的MBSFN子帧中的PDCCH占用的OFDM符号，本发明增加了在MBSFN子帧中携带MBMS的PDCCH占用的OFDM符号的频率，因此 为了有效地利用资源，并且在一定程度上由于MBMS数据传输而避免对PDCCH的干扰。
