的业务增长点。面对此类高速率业务,如何更有效地利用无线频谱资源和功率资源成为迫切需要解决
MBMS技术的引入实现了点到多点利用的问题。E-共享资源下发业务数据,从一定程度上提高了无线
MBMS频资源的利用率。为了更进一步地提升E-多基站协作、分层编码、喷泉码传输、终端协谱效率,
MBMS作传输和动态MBSFN区域配置成为未来E-技术发展的新趋势。其中动态MBSFN区域配置已
有一些初步研究成果,主要分为基于小区位置和基于用户数的配置策略。仔细分析他们各自的优缺点,提出更完善的动态MBSFN区域布置策略是目前工作的方向。例如下一步可以从用户分布的角度出发,更一步地优化配置策略,提升系统频谱和功率资源的利用率。
