摘要： There are provided a wireless communication system for providing diversity gains for multicast services and a method of providing a multicast service. According to the wireless communication system, by transmitting, when terminals are partially distributed in each cell, data to areas where no user exists so as to reduce interference between other MBS (Multicast Broadcast System) zones and other cells that transmit only unicast services, performance deterioration may be minimized.
摘要翻译： 提供了一种用于为多播服务提供分集增益的无线通信系统和提供多播服务的方法。 根据无线通信系统，当将终端部分地分布在每个小区中时，通过发送数据到不存在用户的区域，以减少其他MBS（组播广播系统）区域与仅发送单播服务的其他小区之间的干扰，性能 恶化可能最小化。
